Comparative effectiveness of aerobic, resistance, and combined training on cardiovascular disease risk factors: A randomized controlled trial

Neural Mechanisms in Cardiovascular Health and Disease

Although the neurocardiac axis is central to cardiovascular homeostasis, its dysregulation drives heart failure and cardiometabolic diseases. This review examines the bidirectional interplay between the autonomic nervous system and the heart, highlighting the role of this interplay in disease progression and its therapeutic potential. The autonomic nervous system modulates cardiac function and vascular tone through its sympathetic and parasympathetic branches. However, in heart failure, chronic sympathetic overdrive and parasympathetic withdrawal exacerbate myocardial remodeling and metabolic dysfunction, both of which are exacerbated by cardiometabolic conditions such as obesity and diabetes. These conditions are increasingly recognized to impair neurocardiac regulation, thereby promoting inflammation and adverse outcomes. An important emerging area concerns neuroimmune control, in which the brain orchestrates systemic inflammation through circuits involving the bone marrow, spleen, and other organs, thereby amplifying cardiovascular damage. This neuroimmune axis integrates peripheral signals to influence immune responses that contribute to disease progression. Lifestyle factors, such as stress, sleep, exercise, and diet, affect autonomic and immune balance and, thus, cardiovascular disease. Therapeutically, targeting neurocardiac and neuroimmune pathways pharmacologically or via neuromodulation (eg, vagal or splenic nerve stimulation) offers promise although the clinical translation of the latter remains challenging. In this review, we synthesize preclinical and clinical data to highlight the neurocardiac axis as a critical nexus in heart failure and cardiometabolic disease. Harnessing neuroimmune and neurocardiac interactions may inform precision approaches to reduce the burden of these conditions.

The effect of different exercise types on migraine frequency in individuals with migraine: A pilot study

OBJECTIVES

This study aimed to evaluate the effects of different types and combinations of exercise on migraine attacks and accompanying comorbidities.

BACKGROUND

Combining aerobic and resistance exercises may yield more significant improvements in patients with migraine.

METHODS

This parallel-group randomized controlled study included 24 participants, who were then divided equally into three groups: an aerobic exercise group, a combined exercise group (aerobic and resistance exercises), and a control group. It was conducted at Ege University Hospital between September 2022 and March 2024. Following a 1-month baseline headache diary period, both intervention groups participated in the same aerobic exercises 3 days a week for 12 weeks. The combined exercise group performed five resistance exercises targeting the neck, upper back, and shoulder muscles alongside the aerobic exercises 3 days a week for 12 weeks. Measurements were taken at baseline, after the 3-month intervention period, and after a 2-month follow-up period. The primary outcome was the number of migraine headache days per month. Secondary outcomes included anxiety and depression levels, aerobic capacity, physical activity status, and migraine-related quality of life.

RESULTS

The number of migraine days per month significantly decreased in both the aerobic and combined exercise groups during the post-intervention period, while no significant change was observed in the control group (p < 0.001 for aerobic and combined exercise groups, p = 0.166 for control group). Migraine headache frequency showed a statistically significant decrease in the combined exercise group compared to the aerobic exercise group (p = 0.027). Additionally, both exercise groups showed significant improvements in aerobic capacity (p < 0.001 for both) and physical activity levels (p < 0.001 and p = 0.001, respectively) post-intervention, which were not observed in the control group (p = 0.747 for aerobic capacity, p = 0.05 for physical activity levels). Although no significant effect on depression scores was observed in either exercise group, anxiety scores significantly decreased in the combined exercise group from pre- to post-intervention (p = 0.037). Significant improvements in migraine-related quality of life were observed in both intervention groups (p = 0.018 and p = 0.001, respectively), with no significant difference (p = 0.934). Neither significant change was observed in depression and anxiety scores nor migraine-related quality of life in the control group (p = 0.593, p = 0.438 and 0.081 respectively).

CONCLUSIONS

Aerobic and combined exercise groups showed a reduction in monthly migraine headache frequency without any side effects, with the reduction being statistically more significant in the combined exercise group.

The effect of exercise on cardiovascular disease risk factors in sedentary population: a systematic review and meta-analysis

Objective

The aim of this study (PROSPERO CRD42023443860) was to determine the dose-response associations of exercise on cardiovascular disease risk factors in sedentary populations using systematic evaluation and meta-analysis.

Methods

We conducted a systematic search of the literature up to July 2024 using PubMed, Web of Science, and SCOPUS. Of the 72,704 search records initially identified, 15 studies were considered eligible for systematic evaluation and meta-analysis. The methodological quality of the included literature was assessed using the Cochrane Risk Assessment Tool. Using a random-effects model, we pooled standardized mean differences (SMDs) with 95% confidence intervals (CIs) for key cardiovascular risk factors.

Results

Exercise improved systolic blood pressure [SMD = -0.33 (95% CI, -0.62 to -0.05), p = 0.02], diastolic blood pressure [SMD = -0.52 (95% CI, -0.92 to -0.12), p = 0.01], and resting heart rate [SMD = -0.30 (95% CI, -0.50 to -0.10), p = 0.004]. However, no significant effects were observed for total cholesterol [SMD = -0.03 (95% CI: -0.24 to 0.18), p = 0.78], HDL cholesterol [SMD = 0.06 (95% CI: -0.16 to 0.27), p = 0.6], LDL cholesterol [SMD = -0.21 (95% CI: -0.59 to 0.18), p = 0.29], triglycerides [SMD = -0.11 (95% CI: -0.42 to 0.21), p = 0.51], or body mass index [SMD = 0.01 (95% CI: -0.16 to 0.17), p = 0.94].

Conclusion

Regular exercise with a duration of 30-40 min per session and a frequency of 3-5 sessions per week significantly improves blood pressure and resting heart rate in sedentary populations, but does not appear to affect lipid profiles or body mass index.

Addition of aerobic physical activity to resistance exercise for hip osteoarthritis (PHOENIX): a randomised comparative effectiveness trial

BACKGROUND

Exercise is recommended for hip osteoarthritis, but the most effective programmes for management of symptoms are unknown. We aimed to investigate whether adding aerobic physical activity to resistance exercise would improve hip pain and function more than resistance exercise alone in individuals with hip osteoarthritis.

METHODS

PHOENIX was a randomised comparative effectiveness trial done in Melbourne, Australia. We recruited people with a clinical diagnosis of symptomatic hip osteoarthritis. Participants were randomly assigned (1:1, by use of a web-based system) to aerobic physical activity and resistance exercise or resistance exercise only. Both groups received a home exercise programme and nine consultations with a physiotherapist over 3 months. The co-primary outcomes were change in hip pain severity (numerical rating scale [NRS] 0-10, with higher scores indicating worse outcomes) and function (Western Ontario and McMaster Osteoarthritis Index [WOMAC]; scale 0-68, with higher scores indicating worse outcomes) at 3 months. Analyses were done in the intention-to-treat population. People with lived experience of hip osteoarthritis were involved in the design of the study. This trial is registered with the Australian New Zealand Clinical Trial Registry (ACTRN 12619001297112), and is complete.

FINDINGS

Between Oct 15, 2019, and Sept 13, 2022, 196 participants (134 [68%] women and 62 [32%] men) were randomly assigned to aerobic physical activity and resistance exercise (n=97) or resistance exercise only (n=99). At 3 months, aerobic physical activity and resistance exercise was not more effective in improving hip pain severity (mean difference 0·3 [95% CI -0·3 to 0·8; p=0·36]) or function (mean difference -0·9 [95% CI -3·6 to 1·8; p=0·51]) compared with resistance exercise alone, with both showing a mean improvement in pain (2·4 [SD 1·9] with aerobic physical activity and resistance exercise vs 2·2 [2·1] with resistance exercise only) and function (7·0 [10·4] with aerobic physical activity and resistance exercise vs 8·9 [10·8] resistance exercise only). There were 24 related adverse events with aerobic physical activity and resistance exercise, and 31 with resistance exercise only, none of which were serious.

INTERPRETATION

Despite improvement in pain and function in both groups, adding moderate-intensity aerobic physical activity to resistance exercise did not lead to superior outcomes. Future work could consider higher intensity interval training before concluding no symptomatic benefit of adding aerobic exercise or physical activity to resistance exercise.

Exercise Training Modalities in Young and Middle-Aged Adults With Prehypertension or Hypertension: A Systematic Review and Network Meta-Analysis

Aims

The question of how to choose the right type of exercise to lower blood pressure and cardiovascular risk factors in people worldwide with high blood pressure is not yet fully understood. Thus, the aim of this study was to investigate the effects of various exercise training on blood pressure and cardiovascular risk factors among young and middle-aged adults with prehypertension or hypertension.

Design

Systematic review and network meta-analysis.

Methods

We searched five electronic databases to identify randomized controlled trials that compare exercise training versus a sedentary or sham control group in young and middle-aged adults with prehypertension or hypertension. Review Manager 5.3, Stata15.0, and R4.2.1 software estimated the efficacy of exercise training modalities.

Results

We included 19 eligible articles with 1590 participants to assess five exercise trainings. Our findings indicated that low-middle intensity aerobic exercise (mean difference (MD) = -8.08, 95% confidence interval (CI) = -13.58, -2.58) was superior to all exercise strategies (high-intensity aerobic exercise: MD = -6.53, 95% CI = -12.51, -0.56; high-intensity resistance exercise: MD = -4.95, 95% CI = -11.07, 1.17; low-middle-intensity resistance exercise: MD = -3.49, 95% CI = -12.36, 5.39) compared with control group in lowering systolic blood pressure. Compared with the control strategy, high-intensity resistance exercise (MD = -4.75, 95% CI = -8.00, -1.50), high-intensity aerobic exercise (MD = -4.27, 95% CI = -7.08, -1.45) could lower diastolic blood pressure. The effects of different exercise patterns on cardiovascular risk factors, the results indicated that only low-middle-intensity aerobic exercise significantly improved body mass index (MD = -0.55, 95% CI = -7.08, -1.45), total cholesterol (MD = -19.07, 95% CI = -36.42, -1.72), triglycerides (MD = -14.32, 95% CI = -23.16, -5.48), high-density lipoprotein (MD = 2.29, 95% CI = 0.85, 3.73), and low-density lipoprotein (MD = -13.90, 95% CI = -22.18, -5.63). In addition, no intervention affects heart rate.

Conclusion

Compared with other types of exercise, aerobic exercise can significantly improve systolic blood pressure, while high-intensity resistance or aerobic exercise may significantly improve diastolic blood pressure. In addition, AE-LM is effective in the reduction of risk factors that are contributors to the development of cardiovascular disease. Therefore, this study provides strong evidence to support the selection of appropriate exercise modalities for hypertensive patients.

Exercise interventions to improve physical frailty and physical frailty components in older adults with hypertension: A systematic review

Physical frailty and hypertension are both highly prevalent among older adults. Furthermore, physical frailty may impact the risk-benefit ratio of pharmacological hypertension treatment. Thus, it may be prudent to focus on physical activity and exercise interventions to achieve better patient outcomes that addresses both conditions. This systematic review aimed to investigate the effects of exercise interventions on physical frailty components and hypertension-related outcomes in older adults with hypertension. PubMed/Medline, Embase, Cochrane Library, Cinahl and PEDro were searched for exercise trials in older adults with hypertension, measuring physical frailty or physical frailty components. Preferred Reporting Items for Systematic Review and Meta-Analysis protocol (PRISMA-P) and Physiotherapy Evidence Database (PEDro) scale were used for internal validity. The searches retrieved 4965 titles without duplicates. Ninety-four potential full texts were evaluated, and 30 original studies were included in the review. Mean methodological quality of the included studies was 5.7 out of 10. Only one study measured frailty (using a cumulative deficit model) in older adults with hypertension. Different types of exercise training demonstrated improvements in components of physical frailty. This systematic review shows that there is no evidence whether exercise ameliorates the effects of physical frailty and hypertension and there is a need for more data to be generated.

Moderate intensity continuous training, combined moderate-intensity continuous training vs combined high-intensity interval training in adults with hypertension: Randomized controlled trial

BACKGROUND AND PURPOSE

Despite all efforts to treat hypertension, it is still responsible for 10.8 million deaths annually. The aim of this study was to compare the effects of continuous moderate-intensity training, strength training combined with continuous moderate-intensity training and strength training combined with high-intensity interval training in adults with high blood pressure.

METHODS

A 12-week randomized control trial was performed. A total of 100 volunteers, 51 women and 49 men with hypertension participated. The sample was randomly assigned into three intervention groups and one control group.

RESULTS

All intervention groups significantly improved their hemodynamic parameters, body composition, lipid profile, glucose, and physical fitness as compared to the control group. Both combined training groups showed greater improvements than the moderate-intensity continuous training group. However, the strength group combined with the moderate-intensity continuous group showed the greatest benefits in systolic, diastolic and mean arterial pressure, of -13.4 mmHg, -6.8 mmHg and -8.9 mmHg respectively, abdominal circumference, upper and lower limb strength and VO₂peak, versus the continuous moderate-intensity group; it also achieved greater reductions in systolic and mean blood pressure, up to -6.8 mmHg and 4.3 mmHg respectively, than the strength group combined with the high intensity interval group.

CONCLUSION

Performing a strength training program combined with continuous moderate intensity training, 2 days per week for 12 weeks, produces significant improvements in cardiometabolic biomarkers, body composition, and physical condition of adults with hypertension, with these adaptations being superior to those produced by continuous moderate-intensity training and strength training combined with high-intensity intervallic training.

The effect of exercise therapy on pain, fatigue, bone function and inflammatory biomarkers individuals with rheumatoid arthritis and knee osteoarthritis: a meta-research review of randomized controlled trials

Background

Accumulating evidence suggested the potential role of exercise in alleviating rheumatoid arthritis (RA). However, whether exercise improves physical function (walk test, grip strength, muscle strength, joint assessments) and inflammatory biomarkers in patients with RA is unclear. This umbrella meta-analysis aimed to examine the effect of exercise in patients with RA.

Method

PubMed, Scopus, Web of Science, Embase, and Cochrane Central Library databases were systematically searched for meta-analyses of randomized control trials (RCTs) to retrieve relevant studies. The effect sizes were pooled using a random-effects model, with standardized or weighted mean differences (SMDs or WMDs) and 95% confidence intervals (CIs) as summary statistics.

Results

Seventeen studies were included. The improving effects of exercise on fatigue levels (SMD = -0.28, 95% CI: -0.44, -0.13), pain intensity (ES = -0.50, 95% CI: -0.87, -0.14), disease activity score in joints (DAS) (WMD = -0.54, 95% CI: -0.99, -0.09; and SMD = -0.47, 95% CI: -0.64, -0.30), and ESR (ES = -0.85, 95% CI: -1.66, -0.03) were significant. No significant impact on the hand grip, muscle strength, walk test, joints and inflammatory biomarkers was observed.

Conclusion

Exercise significantly reduces fatigue, pain, DAS, and ESR in RA but shows no impact on grip strength, muscle strength, walk test, joints, or other inflammatory biomarkers. This highlights its role in symptom management rather than broad physiological changes.

A Pilot 24-Week 'Bulk and Cut' Dietary Protocol Combined with Resistance Training Is Feasible and Improves Body Composition and TNF-α Concentrations in Untrained Adult Males

Background/Objectives: This study piloted a 24-week bodybuilding program combining resistance training (RT) with a dietary bulk-and-cut protocol in middle-aged adult males. Methods: Seven untrained males (33 ± 3.0 years; BMI = 35.0 ± 4.6 kg/m2; body fat = 36 ± 5%) completed a 24-week intervention combining RT with a dietary protocol consisting of 12-week cycles of caloric bulking (0-12 weeks) and cutting (12-24 weeks). The participant retention rate was 64%, while compliance with training was 96.7%, and adherence to dietary cycles was over 93%. To assess the preliminary efficacy of the intervention, venous blood samples and measurements of body composition (BodPod), muscle strength, and VO2max (cycle ergometer) were collected at baseline (week 0) and following the bulking (week 12) and cutting (week 24) cycles. Circulating lipids (triglycerides, total, low-density, and high-density cholesterol), C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) were measured in serum. Results: The training led to significant increases in muscle strength, especially in the deadlift (+46%, p < 0.001) and squat (+65%, p < 0.001). Improvements in body composition were characterized by an increase in fat-free mass and a decrease in body fat percentage over the 24-week intervention (+3% and -6%, respectively, p < 0.05). Lipids, CRP, IL-6, and IL-10 did not change significantly, but there was a notable reduction in TNF-α (time effect p = 0.05, pη2 = 0.39), with 15% lower concentrations at week 24 compared to baseline, indicating reduced inflammation. Conclusions: Overall, the pilot intervention achieved high compliance and adherence rates, leading to improvements in body composition and lower resting TNF-α concentrations in a group of middle-aged males with obesity.

The Effects of Concurrent Training Versus Aerobic or Resistance Training Alone on Body Composition in Middle-Aged and Older Adults: A Systematic Review and Meta-Analysis

Introduction and Aim: The beneficial effects of aerobic training (AT) on preventing excess fat mass, and of resistance training (RT) on skeletal muscle adaptation, are well established. However, the effects of concurrent training (CT) compared to AT or RT alone on body composition in middle-aged and older adults are less understood, and therefore, the focus of this meta-analysis. Methods: Three databases, including PubMed, Web of Science, and Scopus, were searched from inception to March 2024. Randomized trials were included if they compared CT versus either AT or RT, and included body composition measures such as fat mass, body fat percentage, waist circumference, visceral fat mass, lean body mass (LBM), muscle mass/volume, or muscle or muscle fiber cross-sectional area (CSA), in middle-aged (50 to <65 years) and older adults (≥65 years). Weighted mean differences (WMD) or standardized mean differences (SMD) and 95% confidence intervals (CIs) were calculated using random effects models. Results: A total of 53 studies involving 2873 participants were included. Overall, CT increased body weight and LBM significantly more, trending toward significantly larger increases in muscle mass and CSA, compared with AT alone. However, there were no significant differences between CT and RT alone, for body weight, BMI, body fat percentage, fat mass, waist circumference, or visceral fat mass. Conclusions: CT is as effective as AT for decreasing body fat measures and as effective as RT for increasing muscle mass in middle-aged and older adults, and it should be recommended accordingly.

The Sustained Athlete Fitness Exam-Outcomes of U.S. National Senior Games Athletes

BACKGROUND/OBJECTIVES

Physical fitness screening measures for older athletes are lacking in clinical and research arenas. This study aims to define the Sustained Athlete Fitness Exam (SAFE), a comprehensive tool developed using age and sex-based normative data from U.S. National Senior Games athletes, and to investigate any SAFE differences by age, sex, sport, or exercise volume.

METHODS

This cross-sectional study engaged 4,659 U.S. National Senior Games athletes (Mage = 67.65, SD = 9.12, 59.1% female). Athletes completed health history questions and physical performance measures addressing cardiovascular, muscular, flexibility, and balance subscales. Scoring applied age and sex norms from the study population. Outcomes were compared by age group, sex, sport, and exercise volume.

RESULTS

All 22 National Senior Games sports were represented in the study population. Health histories revealed low rates of chronic conditions, with 28.5% reporting none. Median weekly cardiovascular and resistance exercise volumes were 240 and 30 min, respectively. Of the 20 points possible on the SAFE, scores ranged from 2 (0.2%) to 20 (0.8%), with a median of 13. SAFE scoring demonstrated minimal differences by age group or sex and aligned predictably by sport. Higher exercise volumes were associated with superior SAFE composite scores, with nearly all subscales following this trend.

CONCLUSION

The SAFE and associated norms offer population-specific comparisons previously unavailable for older athletes, with a tool able to address multiple domains of physical fitness while avoiding ceiling and floor effects. Significance/Implications: These findings provide the opportunity to improve assessment, treatment, preventative medicine, and training support for a growing demographic.

A 10-week multicomponent outdoor exercise program improves hemodynamic parameters and physical fitness in cardiovascular disease adult and elderly patients

This study aimed to assess the effects of a 10-week multicomponent outdoor exercise program on hemodynamic, physical fitness and psychological variables in subjects with CVDs. Twenty participants (12 M and 8 F; age 68.5 ± 8.6 years; BMI 28.49 ± 4.98 kg/m2) suffering from CVDs participated in this randomized controlled study and were allocated into two groups: an experimental group (EG; 6 M, 5 F) who underwent a multicomponent training (i.e., cardiorespiratory, resistance, mobility and breathing exercises; 60’, 2d·wk-1), or a wait-list control group (CG; 6 M, 3 F) who did not engage in any PA. Hemodynamic parameters were assessed through resting heart rate (RHR) and peripheral blood pressure (P-SBP/P-DBP). Physical fitness was assessed via a 30″ chair stand test (30CST), timed up and go (TUG) test, handgrip strength (HGS) test, and 2’ step test (TMST). The health status and quality of life (QoL) were evaluated with short form-12 (SF-12) and World Health Organization QoL (WHOQoL-bref), respectively. After the intervention, EG showed significant reduction in hemodynamic parameters (RHR p < 0.001, ES = 0.98; P-SBP p < 0.001, ES = 0.53; P-DBP: p < 0.001, ES = 0.78), physical fitness (30CST p < 0.001, ES = 0.92; TUG p = 0.001, ES = 0.67; TMST p < 0.05, ES = 0.79) and physical component of SF-12 (PSC-12 p < 0.05, ES = 0.42) compared to CG; no significant changes were observed in HGS, QoL and mental health component of the SF-12 (p > 0.05). The findings showed significant improvements in hemodynamic parameters and physical fitness suggesting the effectiveness of the multicomponent outdoor exercise program in adults and elderly with stabilized CVDs.

Exercise Training After Myocardial Infarction Enhances Endothelial Progenitor Cells Function via NRG-1 Signaling

Vascular regeneration after myocardial infarction (MI) is essential to improve myocardial ischemia, delay post-infarction ventricular remodeling, and improve the long-term prognosis of MI. Endothelial progenitor cells (EPCs) play important roles in the functional repair and homeostatic maintenance of the vascular endothelium. Exercise training stimulates EPC mobilization and increases the number of circulating EPCs, which has beneficial effects on the restoration of vascular integrity and hemodynamic reconstitution. After post-MI exercise training, cardiac function, the myocardial infarct area, and capillary density in the peri-infarct zone were measured. Bone marrow-derived EPCs were isolated from mice to measure the proliferation, migration, and in vitro angiogenesis of EPCs after myocardial infarction exercise. The expression of NRG-1/ErbB4 signaling factor and related proteins in downstream PI3K/AKT signaling pathway were detected, and the level of autocrine NRG-1 in EPCs was detected. Post-MI resistance training, aerobic exercise training, and combined exercise training increased EPC mobilization and proliferation, migration, and tube-forming capacity, promoted myocardial vascular regeneration, improved cardiac function, and reduced infarct size. Exercise training upregulated NRG-1 expression in EPCs, and NRG-1/ErbB4 signaling activated the downstream PI3K/Akt signaling pathway. Moreover, EPCs may have a positive feedback autocrine loop with NRG-1 to improve the function of EPCs and promote vascular repair and regeneration in mice with MI. Exercise training after MI promotes the function of bone marrow-derived EPCs through NRG-1/ErbB4/PI3K/AKT signaling, thus exerting a role in angiogenesis.

Assessment of cardiovascular risk and physical activity: the role of cardiac-specific biomarkers in the general population and athletes

The first part of this Inter-Society Document describes the mechanisms involved in the development of cardiovascular diseases, particularly arterial hypertension, in adults and the elderly. It will also examine how consistent physical exercise during adolescence and adulthood can help maintain blood pressure levels and prevent progression to symptomatic heart failure. The discussion will include experimental and clinical evidence on the use of specific exercise programs for preventing and controlling cardiovascular diseases in adults and the elderly. In the second part, the clinical relevance of cardiac-specific biomarkers in assessing cardiovascular risk in the general adult population will be examined, with a focus on individuals engaged in sports activities. This section will review recent studies that suggest a significant role of biomarkers in assessing cardiovascular risk, particularly the presence of cardiac damage, in athletes who participate in high-intensity sports. Finally, the document will discuss the potential of using cardiac-specific biomarkers to monitor the effectiveness of personalized physical activity programs (Adapted Physical Activity, APA). These programs are prescribed for specific situations, such as chronic diseases or physical disabilities, including cardiovascular diseases. The purposes of this Inter-Society Document are the following: 1) to discuss the close pathophysiological relationship between physical activity levels (ranging from sedentary behavior to competitive sports), age categories (from adolescence to elderly age), and the development of cardiovascular diseases; 2) to review in detail the experimental and clinical evidences supporting the role of cardiac biomarkers in identifying athletes and individuals of general population at higher cardiovascular risk; 3) to stimulate scientific societies and organizations to develop specific multicenter studies that may take into account the role of cardiac biomarkers in subjects who follow specific exercise programs in order to monitor their cardiovascular risk.

Long Non-Coding RNAs in Diabetic Cardiomyopathy: Potential Function as Biomarkers and Therapeutic Targets of Exercise Training

Recent studies emphasize the beneficial effects of exercise on diabetic cardiomyopathy (DCM), adding to the growing body of evidence that underscores the role of exercise in improving health outcomes. Despite this, a notable gap persists in the number of healthcare providers who actively prescribe exercise as a therapeutic intervention for DCM management. In addition, exercise modulates the expression of lncRNAs, which play a pivotal role in DCM progression. Further investigation into this relationship may facilitate the identification of novel biomarkers and therapeutic targets for DCM. This review consolidates recent advances in identifying lncRNAs biomarkers in DCM, summarizing the current knowledge on dysregulated lncRNAs and their molecular mechanisms. Additionally, it offers new insights into the mechanistic roles of lncRNAs, highlighting their potential as biomarkers and therapeutic targets for DCM. Overall, this review aims to inform future research and reinforce the significance of addressing diabetes-related cardiovascular diseases to potentially improve clinical outcomes.

Impact of combined exercise on blood DNA methylation and physical health in older women with obesity

This study examined the effects of a 14-week combined exercise program on blood DNA methylation (DNAm) and its potential biological pathways in normal-weight, overweight, and obese older women. A total of 41 participants were assessed at baseline, 7 weeks, and 14 weeks into the training. Their whole-blood DNAm profiles were measured using the Infinitum MethylationEPIC BeadChip, alongside physical and biochemical health evaluations. The results showed notable health improvements, with decreases in blood pressure and cholesterol levels in the overweight and obese groups. Blood triglycerides were reduced only in the overweight group. Physical performance also improved across all groups. At 14 weeks, 1,043 differentially methylated positions (DMPs) were identified, affecting 744 genes. The genes were linked to biological processes, such as cellular metabolism, with significant pathway enrichment related to oxidative phosphorylation and chemical carcinogenesis. Additionally, the overweight group experienced significant reductions in methylation levels at eight lipogenesis-related genes. Protein EpiScore analysis revealed decreased levels of CCL11, VEGFA, and NTRK3 proteins at 14 weeks compared to baseline. Despite these significant molecular changes, there was no observable difference in DNAm age after the intervention. This study highlights how combined exercise can modify DNAm patterns in older women, particularly in lipogenesis-related genes, but suggests that further research is needed to understand the full implications for biological ageing.

A Comparison of Physical Activity and Exercise Recommendations for Public Health: Inconsistent Activity Messages Are Being Conveyed to the General Public

We examined the similarities and differences between government-supported public health activity recommendations from the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), the National Health Service (NHS), the Department of Health and Aged Care (DHAC), and one of the most renowned public health activity recommendations, the 10,000 Steps Program. The findings derived from our evaluation suggest a lack of consistency in public health activity recommendations, including the nomenclature used to describe aerobic activity, the amount of time required per week to meet the minimum recommendation for moderate and vigorous activity, and variations in the intensities required to meet aerobic activity recommendations. We also found that moderate-intensity activity (3.0 to less than 6.0 METS) is achieved across the lifespan with normal (i.e., mean), rather than vigorous, walking speeds; this suggests the MET level for moderate-intensity activity may need to be re-examined. The suggested strength activities must also be considered to ensure that the activities maintain or improve strength in the general public. Among the reviewed recommendations, none distinguished between physical activity and exercise, which may contribute to the low levels of exercise participation among the general public. Since exercise is medicine, the most recognized government-supported public health activity recommendations should place a greater emphasis on exercise over physical activity. Moreover, given the low levels of activity in the general public, more care should be given to provide a consistent, clear, and direct message regarding activity recommendations.

Physical activity interventions implemented for older people in Sub-Saharan Africa: a scoping review

BACKGROUND

Sub-Saharan Africa mirrors global patterns with an expanding elderly demographic, frequently characterised by a high incidence of non-communicable diseases (NCDs), manifesting as multimorbidity. Physical activity (PA) is a validated intervention for managing the increasing prevalence of NCDs in this demographic.

OBJECTIVE

This review aimed to elucidate the extent of PA interventions implemented in Sub-Saharan Africa for managing NCDs in older people (OP).

ELIGIBILITY CRITERIA

This review synthesised randomised controlled trials published in English since 2010, focusing on PA interventions for managing NCDs or associated risk factors in OP in Sub-Saharan Africa.

SOURCES OF EVIDENCE

The Joanna Briggs Institute methodology for scoping reviews was implemented with searches in the following databases: PubMed, EBSCOhost (Academic Search Premier AfricaWide Information, CINAHL, Health Sources Premier Academic/Nursing), Scopus and ProQuest.

CHARTING METHODS

Extraction and reporting adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Reviews framework, ensuring rigorous and systematic synthesis.

RESULTS

A total of 3754 studies were initially identified, with 67 studies ultimately included after applying the exclusion criteria. The synthesised trials tested primarily supervised structured PA interventions (n=30), education on PA and lifestyle (n=30) and combined structured PA with lifestyle education (n=7). A structured supervised PA regimen combining aerobic exercise at 60-80% of maximum heart rate (three 45-60 min sessions per week) and resistance training starting at 50% of one-repetition maximum (3 weekly sessions of three sets with 10-12 repetitions per muscle group), progressively increasing to 60%, was the most effective in reducing risk factors associated with NCDs in this cohort.

CONCLUSION

This analysis confirms that a structured PA regimen paired with lifestyle education significantly mitigates NCDs in Sub-Saharan Africa's elderly population. Furthermore, it highlights the imperative for further investigation into non-pharmacological strategies, especially those targeting hypertension, diabetes and cognitive health disorders.

Effect of aerobic training versus resistance training for improving cardiorespiratory fitness and body composition in middle-aged to older adults: A systematic review and meta-analysis of randomized controlled trials

This systematic review and meta-analysis aimed to examine the influence of aerobic training (AT) versus resistance training (RT) on cardiorespiratory fitness and body composition in middle-aged to older adults. Four electronic databases including PubMed, Scopus, Cochrane CENTRAL, and web of science, as well as reference lists of included randomized controlled trials (RCTs) were searched from inception to April 2024. Data were pooled by the inverse-variance method and reported as mean differences (MDs) with 95 % confidence intervals (CIs). Thirty-eight RCTs, with a pooled sample of 1682 participants, met our inclusion criteria. Meta-analysis revealed that AT significantly improved VO2max/peak (MD = 1.80, 95 % CI: 0.96 to 2.64, p < 0.0001) and 6-MWT (MD = 18.58, 95 % CI: 10.38 to 26.78, p < 0.00001), and significantly decreased body mass (MD = -1.23, 95 % CI: -1.98 to -0.47, p = 0.001) versus RT. However, changes in lean body mass favored RT over AT. Moreover, changes in VO2max/peak and 6-MWT following AT were significant among both healthy and unhealthy participants, or men and women, after medium-term (< 24 weeks) and long-term (≥ 24 weeks) interventions, and among participants aged ≤65 and >65. Our results propose that AT should be considered an efficient approach to improving cardiorespiratory fitness and overall body composition with aging, particularly in terms of VO2max and 6-MWT performance. However, for improvements in lean body mass, RT may be more beneficial. Therefore, a combination of AT and RT might be optimal for comprehensive fitness and body composition improvements with aging.

The Role of Exercise: Physical Fitness Changes Caused by Hypocaloric Diet and Exercise in Men Who Are Overweight

OBJECTIVE

There is evidence showing the effect of hypocaloric diet and increasing physical activity on weight loss. However, the effect of these factors on body composition and functional capacity remains unclear. Also, it is not clear which type of exercise (aerobic, resistance) has effective health benefits for men who are overweight. The aim of this study is to investigate whether a 12-week combined exercise or walking intervention combined with a hypocaloric diet provides improvements in body composition and functional capacity of men who are overweight compared to those who do not exercise.

METHODS

60 healthy adult men who are overweight were randomized and divided into 3 groups: 1: Hypocaloric Diet + Combined Exercise; 2: Hypocaloric Diet + Walking; 3: Hypocaloric Diet. The exercise groups were trained for 12 wk, 3 days a week and 60 min (60 min\3 days\12 wk). Body composition was determined with Bioelectrical Impedance Analysis (BIA) device, strength parameters with MicroFet 2, functional capacity with 6-min walking test.

RESULTS

Improvement was observed in all groups at the end of 12 wk. The greatest improvement was in the combined exercise group. While the values of the combined exercise group increased in Skeletal Muscle Mass, there was a decline in the walking and non-exercising group. Basal Metabolism was maintained in combined exercise, but a decrease occurred in the non-exercising group. Muscle force increased in combined exercise; however, it was maintained in the legs in the walking group. Cardiorespiratory fitness was at best level in walking group, but there was no difference between combined exercise.

CONCLUSIONS

As a result, a hypocaloric diet without an exercise prescription is sufficient to lose weight in the short term (12 wk) at a certain level. But exercise is more important for body composition, weight management and functional capacity. Long-term and in-depth studies should be conducted to interpret the results better.

The Effects of Aerobic Exercise Training on Testosterone Concentration in Individuals Who are Obese or Have Type 2 Diabetes: A Systematic Review and Meta-Analysis

BACKGROUND

Obesity and type 2 diabetes (T2D) are associated with alterations in testosterone concentrations. While evidence indicates that aerobic training can influence testosterone in healthy populations or females with hyperandrogenism, its impact in individuals with obesity or T2D remains unclear. Thus, the aim of this study was to investigate whether aerobic training can influence circulating testosterone concentrations in individuals with obesity or T2D.

METHODS

EBSCOhost (CINAHL, MEDLINE, SPORTDiscus), PubMed and Embase were searched for articles published until August 2023. Eligible articles included individuals with obesity or T2D that underwent an aerobic exercise intervention with testosterone concentrations measured at baseline and post intervention. Two reviewers independently screened the seven articles included in this meta-analysis and conducted data extraction and risk of bias assessments.

RESULTS

A total of 103 participants (62 men / 41 women) from three randomised controlled trials and four non-randomised controlled trials were included. Effect sizes were computed with random effects models. Aerobic exercise moderately increased testosterone concentrations in men (g = 0.565, 95% CI = 0.307 to 0.822, p < 0.001), but had no significant effect in women (g = -0.523, 95% CI = -1.541, 0.496, p = 0.314). Aerobic exercise had no significant effect on sex hormone-binding globulin or markers of insulin sensitivity (p > 0.05).

CONCLUSIONS

Aerobic training may be used to increase testosterone concentrations in men with obesity or T2D, but potentially has no influence in women. Given the low number of studies, further studies investigating the effect of exercise on circulating sex hormones in men and women with obesity or T2D are needed.

Mitigating disuse-induced skeletal muscle atrophy in ageing: Resistance exercise as a critical countermeasure

The gradual deterioration of physiological systems with ageing makes it difficult to maintain skeletal muscle mass (sarcopenia), at least partly due to the presence of 'anabolic resistance', resulting in muscle loss. Sarcopenia can be transiently but markedly accelerated through periods of muscle disuse-induced (i.e., unloading) atrophy due to reduced physical activity, sickness, immobilisation or hospitalisation. Periods of disuse are detrimental to older adults' overall quality of life and substantially increase their risk of falls, physical and social dependence, and early mortality. Disuse events induce skeletal muscle atrophy through various mechanisms, including anabolic resistance, inflammation, disturbed proteostasis and mitochondrial dysfunction, all of which tip the scales in favour of a negative net protein balance and subsequent muscle loss. Concerningly, recovery from disuse atrophy is more difficult for older adults than their younger counterparts. Resistance training (RT) is a potent anabolic stimulus that can robustly stimulate muscle protein synthesis and mitigate muscle losses in older adults when implemented before, during and following unloading. RT may take the form of traditional weightlifting-focused RT, bodyweight training and lower- and higher-load RT. When combined with sufficient dietary protein, RT can accelerate older adults' recovery from a disuse event, mitigate frailty and improve mobility; however, few older adults regularly participate in RT. A feasible and practical approach to improving the accessibility and acceptability of RT is through the use of resistance bands. Moving forward, RT must be prescribed to older adults to mitigate the negative consequences of disuse atrophy.

Community-Based Exercise Programs Post Spinal Cord Injury Hospitalization: A Pilot Study for a Randomized, Multicenter, Double-Blind Controlled Setting

This study explores the effectiveness of community-based exercise programs for individuals with spinal cord injury (SCI) following hospital discharge. Given the rising incidence of SCI, particularly in South Korea, and the associated long-term disabilities, the necessity for comprehensive post-discharge rehabilitation is paramount. The study focuses on a pilot randomized multicenter double-blind controlled trial, targeting SCI patients who have completed inpatient rehabilitation and are living in the community. The primary aim is to evaluate the impact of structured exercise programs on physical fitness, functional capacity, and overall recovery. The research introduces the SpinalFit program, a community-based intervention designed to enhance muscle strength, cardiopulmonary endurance, and mobility through a combination of aerobic and resistance training. This program addresses the critical need for safe and effective rehabilitation options outside the hospital setting, utilizing circuit training with resistance bands and body-weight exercises tailored to each participant's capacity. The study also investigates barriers to physical activity in the community for SCI patients and the potential role of community exercise centers in bridging this gap. Preliminary findings from this pilot trial are expected to provide valuable insights into optimizing exercise regimens for SCI patients, informing future large-scale studies and contributing to improved post-discharge rehabilitation strategies.

Reflections on four decades of physical activity epidemiology

•Broad topics in physical activity (PA) epidemiology have remained the same over 40 years; specific issues and questions have changed and challenges remain. •Accelerometry has made many advances in PA measurement, but created new methodological challenges. •The benefit of regular PA for a wide array of health outcomes has been well-established, but specificity is still needed about dose response relations. •Interventions in the population have led to increased prevalence of recommended levels of PA, but prevalence is still less than optimal and there are racial and ethnic disparities.

Evaluating the Potential of a Novel Metabolic Syndrome Severity Score to Inform Exercise Interventions for People with Complex Chronic Conditions

Aims: Exercise interventions positively affect numerous cardiometabolic risk factors. To better evaluate the health effects of exercise training, it may be more appropriate to evaluate risk factors together. The Metabolic Syndrome Severity Score (MetSSS) is a composite score representing cardiometabolic risk. Purpose: To evaluate the relationships between physical activity, neuromuscular fitness, exercise capacity, and the MetSSS in a heterogenous sample of people with complex chronic disease. Material and Methods: Fifty-three people with kidney or liver disease and at least one feature of the metabolic syndrome (MetS) were included. Pearson correlations were conducted between physical activity, neuromuscular fitness, exercise capacity, and the MetSSS. Linear regressions were performed for multi-level categorical variables. Independent variables with an association with MetSSS (P ≤ 0.2) were included in a multiple regression analysis. Results: The 6-minute walk test (6MWT) distance was inversely and independently associated with MetSSS [standardized beta coefficient (β) = -0.31, P = 0.04]. No relationship was found between MetSSS and physical activity or neuromuscular fitness. Mean 6MWT in the highest tertile was 550 m (range: 505-620 m) and 346 m (range: 233-408 m) in the lowest. The analysis showed a medium-large between-group effect for the difference in MetSSS for the lowest and highest tertile of 6MWT [Eta squared (η2) = 0.16, P = 0.01]. Conclusions: Exercise capacity was inversely and independently associated with MetSSS in people with complex chronic disease. Clinical trials with exercise interventions are needed to further investigate if improvements in exercise capacity result in clinically significant changes in the MetSSS.

Effects of circuit training and Yoga on biochemical and psychological responses to stress and cardiovascular markers: A randomized clinical trial with nursing and medical students in Southern Brazil

A Randomized Controlled Trial involving 158 Brazilian medical and nursing students assessed one of three conditions over an 8-week period: 1) a circuit training protocol (CTG); 2) a yoga protocol (YG); or 3) no intervention (CG). The objective was to evaluate the effectiveness of circuit training and yoga protocols in reducing perceived mental stress and examining their effects on serum cortisol levels, as well as on traditional cardiovascular risk factors (CRFs), during an academic semester. Mental stress was measured using self-reported stress questionnaires. For the CTG, comparisons of pre- vs. post-intervention data indicated a reduction in self-reported stress levels on a Brazilian scale (p < 0.001) and an international scale (p < 0.05). Regarding CRFs, there was a reduction in waist circumference (WC) (p < 0.05), systolic blood pressure (SBP) (p < 0.05), and heart rate (HR) (p < 0.001). No changes were observed in diastolic blood pressure (DBP) (p = 0.211) and serum cortisol (SC) (p = 0.423). In the YG, pre- vs. post-intervention data indicated a reduction in self-reported stress levels on the ISSL (p < 0.001), in both resistance and exhaustion stress levels on the PSS scale (p < 0.001), and in SC levels (p < 0.001), WC (p < 0.05), and SBP (p < 0.05); however, HR and DBP did not change (p = 0.168 and p = 0.07, respectively) in this group. No changes were noted in any measures in the CG. The intervention protocols demonstrated that both CTG and YG can positively impact mental or biochemical stress responses, as well as CRFs.

The Effectiveness of Exercise in Reducing Cardiovascular Risk Factors Among Adults: A Systematic Review and Meta-Analysis

Cardiovascular disease (CVD) remains one of the major causes of sickness and death in the world. However, lifestyle modifications, such as exercise, can significantly reduce the risk of this disease. This study aimed to assess the effectiveness of various forms of physical activity in reducing CVD risk factors among adults. A comprehensive search of the databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), and Excerpta Medica Database (EMBASE) databases was conducted between January 1, 2014, and May 31, 2024, as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials (RCTs), cohort studies, and observational studies on the impact of aerobic, resistance, or combined training on cardiovascular risk factors in adults (≥18 years) were considered for inclusion. Data relating to primary outcomes, including stroke and myocardial infarction rates, BP, cholesterol levels, and BMI were collected. The Cochrane risk-of-bias tool and the Methodological Index for Non-Randomized Studies (MINORS) checklist were used for quality and bias assessment. Meta-analyses were performed using the RevMan software, with heterogeneity evaluated by I² statistics; 17 studies, including 11 RCTs and six cohort studies, met the inclusion criteria. There was a significant reduction in the mean systolic BP (SBP) by 3.32 mmHg [95% confidence interval (CI): 0.85-5.78 mmHg; p<0.0001] and mean diastolic BP (DBP) by 2.99 mmHg (95% CI: 2.34-3.64 mmHg; p < 0.00001) after exercise interventions. Moreover, cholesterol levels and BMI values improved with exercise. Those who exercised had a lower risk of stroke or heart attack compared with the controls [odds ratio (OR): 0.57; 95% CI: 0.28-1.14; p >0.0001], although there was substantial heterogeneity in effect size across the studies (I² = 98%). Different types of physical activity (i.e., aerobic, resistance, or combined exercise) can effectively reduce key cardiovascular risk factors, including BP, cholesterol levels, and BMI values. Regular physical activity is still regarded as the most effective preventive measure against CVD, despite inconsistencies in research findings. Future studies should aim to identify optimal exercise programs and their long-term effects on diverse populations.

Multicomponent versus aerobic exercise intervention: Effects on hemodynamic, physical fitness and quality of life in adult and elderly cardiovascular disease patients: A randomized controlled study

OBJECTIVE

Cardiovascular diseases (CVDs) remain a leading cause of mortality globally, emphasizing the need for effective preventive measures. This study aimed to investigate the effects of a multicomponent compared to an aerobic training program on the hemodynamic parameters, physical fitness, psychophysical health status and quality of life (QoL) of adults and elderly with stabilized CVDs.

METHODS

Thirty-three subjects (19M and 14F; age 69.5 ± 4.9 years; BMI 27.34 ± 4.95 kg/m2) suffering from CVDs voluntarily participated in this 10-week randomized controlled study and were allocated into three groups: multicomponent training group (MTG; 6M, 6F; cardiorespiratory, resistance, flexibility and breathing exercises; 60', 2d·wk-1), aerobic training group (ATG; 7M, 5F; aerobic-only training; 60', 2d·wk-1) or a wait-list control group (CG; 6M, 3F; no PA). Hemodynamic parameters were assessed through resting hearth rate (RHR) and peripheral-systolic and diastolic blood pressure (P-SBP/P-DBP). Physical fitness was assessed via a 30" chair stand test (30CST), timed up and go (TUG) test, handgrip strength (HGS) test, and 2' step test (TMST). The health status, QoL and enjoyment were evaluated with short form-12 (SF-12), world health organization quality of life-bref (WHOQoL-bref) and physical activity enjoyment scale (PACES), respectively.

RESULTS

After the intervention, MTG showed significant improvements in hemodynamic parameters (95 % CI, RHR: 2.76 to 9.07; P-SBP: 3.28 to 13.71; P-DBP: 3.56 to 8.94; p < 0.001), physical fitness (95 % CI, 30CST: 4.42 to -1.90; TUG: 0.56 to 1.58; TMST: 35.24 to -18.58; Dominant HGS: 4.00 to -1.65; Undominant HGS: 2.87 to -0.79, p < 0.001) and enjoyment (PACES: 15.18 to -5.48, p < 0.001) compared to CG; ATG showed significant improvement in hemodynamic parameters (95 % CI, RHR: 1.76 to 8.07; P-SBP: 3.19 to 13.63; P-DBP: 4.47 to 9.85, p < 0.001), physical fitness (95 % CI, 30CST: 2.59 to -0.07; TUG: 0.03 to 1.05; Dominant HGS: 2.42 to -0.07, p < 0.05; TMST: 36.08 to -19.41, p < 0.001) and enjoyment (PACES: 14.68 to -4.98, p < 0.001) compared to CG. No significant changes were observed in QoL and SF-12 (p > 0.05). Significant differences between MTG and ATG were only found in physical fitness variables (95 % CI, 30CST: 3.21 to -0.45, p < 0.01; Dominant HGS: 0.00 to 3.00, p < 0.05).

CONCLUSIONS

Findings showed significant improvements in hemodynamic parameters and physical fitness suggesting the effectiveness of the multicomponent exercise program, similar to aerobic-only training, and greater efficacy for lower limb strength and dominant hand grip strength in adults and elderly with stabilized CVDs. Both exercise groups showed similar levels of enjoyment.

Sex-Specific Variations in Glycated Hemoglobin Responses to Structured Exercise in Type 2 Diabetes: Healthcare Implications of Walking and Strength Training on Glycemic Control

Type 2 diabetes mellitus (T2DM) affects one in ten individuals in the United States, with rates expected to rise significantly. This novel study aimed to evaluate the impact of a structured exercise program on glycated hemoglobin (HbA1c) levels among males and females with T2DM, and to compare the effects of different volumes of combined aerobic and resistance exercise. A total of 67 adult participants with T2DM were randomly assigned to two groups: Group 1 (exercise classes and walking sessions) and Group 2 (exercise classes only). After 10 weeks, 39 participants completed the intervention and 34 had complete HbA1c records. Results indicated a significant improvement in HbA1c levels overall, with males exhibiting a greater decrease compared to females. Minimal baseline differences were observed between the walking and non-walking groups and improvements in HbA1c were noted in both groups with no significant differences. These findings suggested potential sex-specific differences in response to structured exercise programs. The study highlighted the importance of tailored exercise interventions in healthcare while managing T2DM. Further research is necessary to optimize exercise prescriptions and evaluate long-term benefits, but the current evidence supports structured exercise as a valuable component of comprehensive diabetes care. This research underscores the need for personalized approaches in exercise regimens, contributing to the growing body of knowledge on sex-specific responses to T2DM interventions.

Dexamethasone-Induced Arterial Stiffening Is Attenuated by Training due to a Better Balance Between Aortic Collagen and Elastin Levels

PURPOSE

Although the cardioprotective benefits of exercise training are well known, the effects of training on dexamethasone (DEX)-induced arterial stiffness are still unclear. This study was aimed at investigating the mechanisms induced by training to prevent DEX-induced arterial stiffness.

METHODS

Wistar rats were allocated into 4 groups and submitted to combined training (aerobic and resistance exercises, on alternate days, 60% of maximal capacity, for 74 d) or were kept sedentary: sedentary control rats (SC), DEX-treated sedentary rats (DS), combined training control (CT), and DEX-treated trained rats (DT). During the last 14 d, rats were treated with DEX (50 μg/kg per body weight, per day, s.c.) or saline.

RESULTS

DEX increased PWV (+44% vs +5% m/s, for DS vs SC, p<0.001) and increased aortic COL 3 protein level (+75%) in DS. In addition, PWV was correlated with COL3 levels (r=0.682, p<0.0001). Aortic elastin and COL1 protein levels remained unchanged. On the other hand, the trained and treated groups showed lower PWV values (-27% m/s, p<0.001) vs DS and lower values of aortic and femoral COL3 compared with DS.

CONCLUSION

As DEX is widely used in several situations, the clinical relevance of this study is that the maintenance of good physical capacity throughout life can be crucial to alleviate some of its side effects, such as arterial stiffness.

Effects of five types of exercise on vascular function in postmenopausal women: a network meta-analysis and systematic review of 32 randomized controlled trials

Background

As women age, especially after menopause, cardiovascular disease (CVD) prevalence rises, posing a significant global health concern. Regular exercise can mitigate CVD risks by improving blood pressure and lipid levels in postmenopausal women. Yet, the optimal exercise modality for enhancing vascular structure and function in this demographic remains uncertain. This study aims to compare five exercise forms to discern the most effective interventions for reducing cardiovascular risk in postmenopausal women.

Methods

The study searched PubMed, Web of Science, Cochrane, EBSCO, and Embase databases. It conducted a network meta-analysis (NMA) of randomized controlled trials (RCTs) on five exercise interventions: continuous endurance training (CET), interval training (INT), resistance training (RT), aerobic combined with resistance training (CT), and hybrid-type training (HYB). Outcome measures included carotid artery intima-media thickness (IMT), nitric oxide (NO), augmentation index (AIx), pulse wave velocity (PWV), and flow-mediated dilatation (FMD) of the brachial artery. Eligible studies were assessed for bias using the Cochrane tool. A frequentist random-effects NMA was employed to rank exercise effects, calculating standardized mean differences (SMDs) with 95% confidence intervals (CIs).

Results

The analysis of 32 studies (n = 1,427) indicates significant increases in FMD with CET, INT, RT, and HYB in postmenopausal women. Reductions in PWV were significant with CET, INT, RT, CT, and HYB. AIx decreased significantly with INT and HYB. CET, INT, and CT significantly increased NO levels. However, no significant reduction in IMT was observed. SUCRA probabilities show INT as most effective for increasing FMD, CT for reducing PWV, INT for decreasing AIx, CT for lowering IMT, and INT for increasing NO in postmenopausal women.

Conclusion

The study demonstrates that CET, INT, RT, and HYB have a significant positive impact on FMD in postmenopausal women. Furthermore, all five forms of exercise significantly enhance PWV in this population. INT and HYB were found to have a significant positive effect on AIx in postmenopausal women, while CET, INT, and CT were found to significantly improve NO levels. For improving vascular function in postmenopausal women, it is recommended to prioritize INT and CT exercise modalities. On the other hand, as CET and RT were not ranked at the top of the Sucra value ranking in this study and were less effective than INT and CT as exercise interventions to improve vascular function in postmenopausal women, it is not recommended that CET and RT be considered the preferred exercise modality.

Effect of high-intensity interval training vs. moderate-intensity continuous training on cardiometabolic risk factors in overweight and obese individuals

OBJECTIVES

Our study aims to compare the effects of an 8-week high-intensity interval training (HIIT) vs. moderate-intensity continuous training (MICT) on cardiometabolic risk factors and on serum leptin levels in overweight and obese individuals.

METHODS

Our quasi-experimental study involved 36 students who were assigned to HIIT, MICT or the control group. Using a bicycle ergometer, participants in the HIIT group performed 25 min of HIIT and those in the MICT group performed 35 min of moderate-intensity continuous exercise for three days a week for 8 weeks. Body composition estimated by bioimpedance analysis, blood lipids and serum leptin were measured pre-exercise and 8 weeks post-exercise.

RESULTS

After 8 weeks of exercise, the participants in the MICT group showed a significant reduction in weight (p<0.01) and body mass index (BMI) (p<0.05). In the HIIT group, although weight reduction was noticed, the difference was not statistically significant compared to the pre-exercise values. In the control group, participants had a significant increase in their weight, BMI, and total body fat (p<0.05). On performing an inter-group comparison of the magnitude of change in body weight and BMI over 8 weeks of exercise, no difference was seen between the HIIT and MICT groups. No difference was observed in body fat indices and levels of random blood glucose, blood lipids and serum leptin pre and 8 weeks post-exercise.

CONCLUSIONS

On comparing the change in body weight and BMI over 8 weeks, no significant difference was found between the HIIT and MICT groups. However, HIIT was notably more time efficient.

The effect of resistance training in reducing hot flushes in post-menopausal women: A meta-analysis

OBJECTIVE

The objective of this meta-analysis is to study the effect of different strengths of resistance training programs on the severity and frequency of hot flushes in postmenopausal women with vasomotor symptoms.

BACKGROUND

Menopause is defined as the state in which the menstrual cycle of a biological female spontaneously comes to a halt for a period of about 1 year. Through a detailed analysis of much of the research, it is found that the resistance training program is beneficial not only for reducing the severity as well as the frequency of hot flushes in postmenopausal women.

MATERIALS AND METHODS

Online research was conducted through databases such as PubMed, Cochrane Trial Register, and Google Scholar till the 20th of March 2023. The Review Manager (version 5.4.1) was used to statistically analyze the data from the studies. Studies meeting the inclusion criteria, comparing the vasomotor symptoms in resistance training groups as compared to control were used for this meta-analysis. The primary outcome of interest was the alleviation of hot flushes in the resistance training group. Random-effect model was used to pool the studies and the result was reported in SMD with 95% Confidence Interval (CI).

RESULTS

5 studies were selected for this review. Statistical analysis shows that vasomotor symptoms were more common in the control group and decreased significantly in the resistance training group after the intervention (SMD = -1.31, 95% CI: -1.85 to -0.77, p = 0.002).

CONCLUSION

Resistance Training significantly affects vasomotor symptoms and can be considered for such symptoms in postmenopausal women.

Evaluating the impact of a combined aerobic and strength training intervention on the physical performance of male Chinese People's Liberation Army air force pilots

This study aimed to assess the impact of a 16-week combined training program on the physical performance of 20 male Air Force pilots, with an average age of 31.87 ± 2.75 years, body mass of 76.33 ± 0.79 kg, and height of 175.55 ± 3.65 cm. This intervention encompassed both aerobic and strength training, involving six weekly training sessions. The participants were categorized into two groups based on their initial physical performance levels to explore potential baseline influences on post-intervention adaptations. The study measured changes in estimated maximal oxygen uptake (VO2 max), maximal strength, muscular endurance, and long jump performance before and after the training program. Repeated measures ANOVA revealed significant differences over time in theV ˙ O2 max (F = 86.898; p < 0.001;η p 2  = 0.821), handgrip strength right hand (F = 160.480; p < 0.001;η p 2  = 0.894), handgrip strength left hand (F = 102.196; p < 0.001;η p 2  = 0.843), squat maximal strength (F = 525.725; p < 0.001;η p 2  = 0.965), push-ups (F = 337.197; p < 0.001;η p 2  = 0.974), sit up (F = 252.500; p < 0.001;η p 2  = 0.930) and standing long jump (F = 521.714; p < 0.001;η p 2  = 0.965). In conclusion, the 16-week combined training regimen significantly enhanced the physical performance of Air Force pilots, regardless of their initial performance levels.

Effects of exercise on sleep in patients with epilepsy: A systematic review

Exercise interventions in epilepsy have been shown to improve seizure frequency, physical capacity, quality of life, mood, and cognitive functioning. However, the effectiveness of exercise in improving sleep in epilepsy is less clear. The purpose of this report is to identify the published literature regarding exercise interventions in people with epilepsy to determine 1) what proportion of published clinical trials assess sleep as an outcome, and 2) what benefits of exercise interventions on sleep have been observed. We searched the PubMed, PsycINFO, and SCOPUS electronic databases using the search terms "epilepsy AND [exercise OR physical activity]" and identified 23 articles reporting on 18 unique clinical trials. Nine studies were conducted in adults, five in children, and four in adults and children with active seizures, controlled seizures, or both. Exercise modalities included aerobic exercise, strength training, walking, and yoga, among others, and some also included educational and motivational components. Exercise effects on sleep were tested in four studies, two of which only included indirect measures of sleep- and rest-related fatigue, with mixed results. Of the two reports assessing sleep directly, one reported marginal non-significant improvements in subjective sleep quality and no improvements in objective sleep quality in children after twelve weeks of walking, and the other reported no benefits in subjective sleep quality after twelve weeks of combined aerobic, strength, and flexibility training in adults. Given the health benefits of sleep and detrimental effects of sleep deprivation in epilepsy, epilepsy researchers need to assess the effects of exercise interventions on sleep.

Oxidative Stress in Military Missions-Impact and Management Strategies: A Narrative Analysis

This narrative review comprehensively examines the impact of oxidative stress on military personnel, highlighting the crucial role of physical exercise and tailored diets, particularly the ketogenic diet, in minimizing this stress. Through a meticulous analysis of the recent literature, the study emphasizes how regular physical exercise not only enhances cardiovascular, cognitive, and musculoskeletal health but is also essential in neutralizing the effects of oxidative stress, thereby improving endurance and performance during long-term missions. Furthermore, the implementation of the ketogenic diet provides an efficient and consistent energy source through ketone bodies, tailored to the specific energy requirements of military activities, and significantly contributes to the reduction in reactive oxygen species production, thus protecting against cellular deterioration under extreme stress. The study also underlines the importance of integrating advanced technologies, such as wearable devices and smart sensors that allow for the precise and real-time monitoring of oxidative stress and physiological responses, thus facilitating the customization of training and nutritional regimes. Observations from this review emphasize significant variability among individuals in responses to oxidative stress, highlighting the need for a personalized approach in formulating intervention strategies. It is crucial to develop and implement well-monitored, personalized supplementation protocols to ensure that each member of the military personnel receives a regimen tailored to their specific needs, thereby maximizing the effectiveness of measures to combat oxidative stress. This analysis makes a valuable contribution to the specialized literature, proposing a detailed framework for addressing oxidative stress in the armed forces and opening new directions for future research with the aim of optimizing clinical practices and improving the health and performance of military personnel under stress and specific challenges of the military field.

Potential regulatory role of epigenetic modifications in aging-related heart failure

Heart failure (HF) is a serious clinical syndrome and a serious development or advanced stage of various heart diseases. Aging is an independent factor that causes pathological damage in cardiomyopathy and participates in the occurrence of HF at the molecular level by affecting mechanisms such as telomere shortening and mitochondrial dysfunction. Epigenetic changes have a significant impact on the aging process, and there is increasing evidence that genetic and epigenetic changes are key features of aging and aging-related diseases. Epigenetic modifications can affect genetic information by changing the chromatin state without changing the DNA sequence. Most of the genetic loci that are highly associated with cardiovascular diseases (CVD) are located in non-coding regions of the genome; therefore, the epigenetic mechanism of CVD has attracted much attention. In this review, we focus on the molecular mechanisms of HF during aging and epigenetic modifications mediating aging-related HF, emphasizing that epigenetic mechanisms play an important role in the pathogenesis of aging-related CVD and can be used as potential diagnostic and prognostic biomarkers, as well as therapeutic targets.

A Mobile Health Resistance Training Intervention Using Outdoor Gym Equipment: Process Evaluation of the Ecofit Effectiveness Randomized Controlled Trial

BACKGROUND

Few mobile health resistance-based physical activity interventions have targeted community-dwelling adults. "Ecofit" is a multicomponent intervention that promotes resistance and aerobic activities using smartphone technology, outdoor gyms, and social support. This study evaluated process evaluation outcomes of the ecofit randomized controlled trial: (1) the acceptability and usability of the ecofit smartphone app and app user workouts; (2) perceptions of factors influencing outdoor gym use; and (3) the fidelity, reach, recruitment, and dose received of the ecofit program.

METHODS

Process data were collected through program evaluation surveys at 3 months, and app usage data were collected via the intervention platform for up to 3 months. Data were analyzed using descriptive statistics.

RESULTS

The survey was completed by 57% (n = 69) of eligible participants. The majority (93%) believed the app provided them with sufficient information to perform muscle-strengthening activities. Approximately half (51%) agreed that the goal-setting function encouraged them to complete their workouts, and 42% agreed that the self-assessment helped them monitor progress. "Proximity" to outdoor gyms emerged as the most important factor for choosing locations to workout (mean = 5.5, SD = 1.1). Participants logged a median of 5.5 (interquartile range = 19) workouts and 1 (interquartile range = 1) upper- and lower-body muscular fitness self-assessment.

CONCLUSIONS

The ecofit app provided participants with sufficient skills to perform unsupervised resistance training exercises using mobile health. Only half of the participants regarded self-assessments and goal setting as useful, suggesting a need for modifications to how these are implemented. Mobile health remains a promising delivery platform to promote unsupervised resistance training, although more research is needed to improve uptake.

The association between marijuana and e-cigarette use and exercise behavior among adults

Background

As the prevalence of marijuana and e-cigarette use among American adults rises and the perceived risk decreases, more information is needed on the potential costs and benefits of marijuana and e-cigarette use, including patterns of exercise. Prior studies have found mixed results, lacked data on types of exercise, and involved only adolescents and young adults. Thus, the current study explored whether marijuana and e-cigarette use are associated with strength training, walking for exercise, or general physical activity among adults in the United States.

Method

2,591 adults from Wave V of the National Longitudinal Study of Adolescent to Adult Health (2016-2018) comprised the sample. Separate one-way analyses of variance (ANOVAs) and post hoc tests examined whether participants' marijuana and e-cigarette use predicted their exercise, while follow-up analyses of covariance (ANCOVAs) probed significant effects.

Results

Results indicated that participants' marijuana and e-cigarette use predicted their walking for exercise, with marijuana users walking the highest number of times per week, followed by non-users, e-cigarette users, and dual users. However, this effect only approached significance after controlling for covariates. There were no significant differences in strength training or general exercise between groups.

Conclusion

These findings challenge the stereotype that marijuana and e-cigarette users are less active than non-users, and future research should examine the potential mechanisms of these findings.

Aerobic, resistance, or combined exercise training and cardiovascular risk profile in overweight or obese adults: the CardioRACE trial

BACKGROUND AND AIMS

To determine the comparative efficacy of resistance, aerobic, and combined resistance plus aerobic exercise on cardiovascular disease (CVD) risk profile.

METHODS

This randomized controlled trial enrolled 406 adults aged 35-70 years with overweight or obesity and elevated blood pressure. Participants were randomly assigned to resistance (n = 102), aerobic (n = 101), combined resistance plus aerobic exercise (n = 101), or no-exercise control (n = 102). All exercise participants were prescribed 1 h of time-matched supervised exercise (the combination group with 30 min of each resistance and aerobic exercise) three times per week for 1 year. The primary outcome was the change from baseline to 1 year in the standardized composite Z-score of four well-established CVD risk factors: systolic blood pressure, low-density lipoprotein (LDL) cholesterol, fasting glucose, and per cent body fat.

RESULTS

Among 406 participants (53% women), 381 (94%) completed 1-year follow-up. Compared with the control group, the composite Z-score decreased at 1 year, which indicates improved CVD risk profile, in the aerobic {mean difference, -0.15 [95% confidence interval (CI): -0.27 to -0.04]; P = .01} and combination [mean difference, -0.16 (95% CI: -0.27 to -0.04); P = .009] groups, but not in the resistance [mean difference, -0.02 (95% CI: -0.14 to 0.09); P = .69] group. Both aerobic and combination groups had greater reductions in the composite Z-score compared with the resistance group (both P = .03), and there was no difference between the aerobic and combination groups (P = .96). Regarding the four individual CVD risk factors, only per cent body fat decreased in all three exercise groups at 1 year, but systolic blood pressure, LDL cholesterol, and fasting glucose did not decrease in any exercise groups, compared with the control group.

CONCLUSIONS

In adults with overweight or obesity, aerobic exercise alone or combined resistance plus aerobic exercise, but not resistance exercise alone, improved composite CVD risk profile compared with the control.

Resistance Training in Cardiovascular Diseases: A Review on Its Effectiveness in Controlling Risk Factors

Cardiovascular Disease (CVD), a term encompassing various disorders affecting the heart and blood vessels, includes coronary artery disease (CAD). CAD is primarily due to the development of atherosclerotic plaques that disrupt blood flow, oxygenation, and nutrient delivery to the myocardium. Risk factors contributing to CAD progression include smoking, hypertension, diabetes mellitus (DM), dyslipidaemia, and obesity. While aerobic exercise (AE) has shown promising results in controlling CVD risk factors, the impact of resistance training (RT) has not been extensively investigated. This review aims to describe the effects of RT on CVD risk factors based on studies retrieved from PubMed and Google Scholar databases. Both isometric and isotonic RT have been found to decrease systolic blood pressure (SBP), diastolic blood pressure, or mean arterial pressure, with SBP showing a more significant reduction. Hypertensive patients engaging in RT alongside a calorie-restricted diet demonstrated significant improvements in blood pressure. RT is associated with increased nitric oxide bioavailability, sympathetic modulation, and enhanced endothelial function. In type-2 DM patients, 8-12 weeks of RT led to improvements in fasting blood glucose levels, insulin secretion, metabolic syndrome risk, and glucose transporter numbers. Combining AE with RT had a more significant impact in reducing insulin resistance and enhancing blood glucose compared to performing exercises separately. It also significantly decreased total cholesterol, triglycerides, and low-density lipoprotein levels while increasing high-density lipoprotein within 12 weeks of application. However, improvements are considered insignificant when lipid levels are already low to normal at baseline. The administration of RT resulted in weight loss and improved body mass index, with more pronounced effects seen when combining AE with RT and a calorie-restricted diet. Considering these results, the administration of RT, either alone or in combination with AE, proves beneficial in rehabilitating CAD patients by improving various risk factors.

Effects of lifestyle factors on leukocytes in cardiovascular health and disease

Exercise, stress, sleep and diet are four distinct but intertwined lifestyle factors that influence the cardiovascular system. Abundant epidemiological, clinical and preclinical studies have underscored the importance of managing stress, having good sleep hygiene and responsible eating habits and exercising regularly. We are born with a genetic blueprint that can protect us against or predispose us to a particular disease. However, lifestyle factors build upon and profoundly influence those predispositions. Studies in the past 10 years have shown that the immune system in general and leukocytes in particular are particularly susceptible to environmental perturbations. Lifestyle factors such as stress, sleep, diet and exercise affect leukocyte behaviour and function and thus the immune system at large. In this Review, we explore the various mechanisms by which lifestyle factors modulate haematopoiesis and leukocyte migration and function in the context of cardiovascular health. We pay particular attention to the role of the nervous system as the key executor that connects environmental influences to leukocyte behaviour.

Role of Resistance Exercise in Cardiology

Resistance exercise is a form of exercise that increases muscular strength and endurance by exercising a muscle or muscle group against external resistance. Resistance exercises have an important potential in preventing cardiac diseases, increasing treatment efficiency, and improving quality of life. In spite of the fact that the vast majority of cardiology research to date has focused on aerobic exercise, an increasing number of studies on resistance exercise have been published in the past few years. Although resistance exercise was combined with aerobic exercise in most of these studies, its isolated efficacy was also examined. In conditions such as coronary artery disease, peripheral artery disease, heart failure, arrhythmias, and cardiac rehabilitation, resistance exercise (RE) is regarded as a potentially beneficial approach. In addition to interventional and medical treatments, resistance exercise can also be considered as a cost-effective and sustainable method. The effects of resistance exercise on a variety of cardiovascular conditions were investigated in this evaluation of the literature.

Physical Exercise-Induced DNA Methylation in Disease-Related Genes in Healthy Adults-A Systematic Review With Bioinformatic Analysis

ABSTRACT

Vasileva, F, Hristovski, R, Font-Lladó, R, Georgiev, G, Sacot, A, López-Ros, V, Calleja-González, J, Barretina-Ginesta, J, López-Bermejo, A, and Prats-Puig, A. Physical exercise-induced DNA methylation in disease-related genes in healthy adults-A systematic review with bioinformatic analysis. J Strength Cond Res 38(2): 384-393, 2024-This study aimed to systematically review the existing literature regarding physical exercise (PE) and DNA methylation (DNAm) in healthy adults. Specific goals were to (a) identify differently methylated genes (DMGs) after PE intervention, their imprinting status, chromosome and genomic location, function, and related diseases; and (b) to screen for core genes and identify methylation changes of the core genes that can be modified by PE intervention. Our search identified 2,869 articles from which 8 were finally included. We identified 1851 DMGs ( p < 0.05) after PE intervention, although 45 of them were imprinted. Aerobic exercise (AE) seems to induce more DNA hypermethylation rather than hypomethylation, whereas anaerobic exercise (AN) seems to induce more DNA hypomethylation rather than hypermethylation. Aerobic exercise induced highest % of methylation changes on chromosome 6, whereas AN and mixed type (MT) on chromosome 1. Mixed type induced higher % of methylation changes close to transcription start site in comparison to AE and AN. After PE intervention, DMGs were mainly involved in fat metabolism, cell growth, and neuronal differentiation, whereas diseases regulated by those genes were mainly chronic diseases (metabolic, cardiovascular, neurodegenerative). Finally, 19 core genes were identified among DMGs, all related to protein metabolism. In conclusion, our findings may shed some light on the mechanisms explaining PE-induced health benefits such as the potential role that PE-induced DNAm may have in disease prevention and disease treatment.

Effects of blood flow restriction training on muscle fitness and cardiovascular risk of obese college students

Purpose: The aim of this study was to investigate the effect of blood flow restriction (BFR) combined with low-intensity resistance training (RT) on cardiovascular risk factors in obese individuals. Methods: Twenty-six male obese college students were recruited and randomly assigned to a control group (CON, n = 8), a low-intensity RT group (RT, n = 9), and a combined BFR training and low-intensity RT group (BFRT, n = 9). Results: The subjects in BFRT group showed significant reductions in body fat percentage and waist-to-hip ratio and a significant increase in lean mass and muscle mass; the peak torque, peak power, and endurance ratio of knee extensors and elbow flexors were significantly upregulated; the root mean square (RMS) for the medial femoral muscle, lateral femoral muscle and biceps significantly increased; the diastolic blood pressure (DBP) showed a significant decrease. The BFRT group also showed significant up-regulations in RMS of the difference between the adjacent R-R intervals (RMSSD), high-frequency power (HF) of parasympathetic modulatory capacity, the standard deviation of R-R intervals (SDNN) of overall heart rate variability (HRV) changes and low-frequency power (LF) of predominantly sympathetic activity. In addition, glycated hemoglobin (HbA1C), insulin resistance index (HOMA-IR) and fasting blood glucose (FBG) were all significantly downregulated in BFRT group. In parallel, low-density lipoprotein (LDL-C) significantly reduced while high-density lipoprotein (HDL-C) significantly increased in BFRT group. Conclusion: BFR combined with low-intensity RT training effectively improved body composition index, increased muscle mass, improved neuromuscular activation, enhanced muscle strength and endurance, which in turn improved abnormal glucolipid metabolism and enhanced cardiac autonomic regulation.

Resistance Training Reduces Blood Pressure: Putative Molecular Mechanisms

Arterial hypertension is a multifactorial clinical condition characterized by higher blood pressure levels. The main treatment for controlling high blood pressure consists of drug therapy, but the scientific literature has been pointing to the efficiency of aerobic and resistance exercises acting in a therapeutic and/or preventive way to reduce and control the blood pressure levels. Resistance training is characterized by sets and repetitions on a given muscle segment that uses overload, such as machine weights, bars, and dumbbells. As it successfully affects a number of variables associated to practitioners' functional and physiological features as well as emotional and social variables, resistance training has been a crucial part of physical exercise programs. Several reports highlight the various adaptive responses it provides, with a focus on the improvement in strength, balance, and muscular endurance that enables a more active and healthy lifestyle. Resistance training programs that are acute, sub-chronic, or chronic can help people with varying ages, conditions, and pathologies reduce their arterial hypertension. However, molecular mechanisms associated with resistance training to reduce blood pressure still need to be better understood. Thus, we aimed to understand the main effects of resistance training on blood pressure as well as the associated molecular mechanisms.

Arterial Health After Preeclampsia: Role of Chronic Hypertension in the Early Vascular Aging (EVA) Study

BACKGROUND

Preeclampsia (PE) is associated with increased cardiovascular risk. Recent data have shown worse left ventricular remodeling and diastolic function in women with PE and persistent hypertension (HTN). We performed a comprehensive arterial hemodynamic assessment to evaluate the contribution of persistent HTN on arterial health after PE.

METHODS

We recruited 40 women with PE history and 40 age-matched controls (6 months to 6 years postpartum). We evaluated arterial hemodynamics with validated techniques combining applanation tonometry and transthoracic echocardiography, comparing three groups: previous PE with persistent HTN (PE-HTN), previous PE with normalized blood pressure (PE-noHTN) and controls, using multivariable linear regression adjusted for age, body surface area, heart rate, diabetes, smoking history, creatinine, and gravidity.

RESULTS

Eight (20%) of the post-PE women had persistent HTN. Mean age was 35.8 ± 3.9 years, median number of pregnancies was 2 (range 1-7), and time since last pregnancy 2.1 (range 0.5-5.7) years (not different between groups, P > 0.05). Compared to controls and to PE-noHTN, PE-HTN had higher aortic stiffness, wave reflections, pulsatile, and steady arterial load (P < 0.05 for each). Among PE-noHTN, aortic stiffness, wave reflections and steady arterial load were worse than controls (P < 0.05 for each), with smaller effect sizes.

CONCLUSIONS

This is the most comprehensive assessment of arterial hemodynamics and first to demonstrate the contribution of persistent HTN on worse arterial health following PE. Since measures of arterial health are associated with cardiovascular events in the population, the combination of previous PE and chronic HTN may represent a higher risk subgroup who could benefit from targeted prevention strategies.

Exercise rehabilitation to treat sarcopenia in pediatric transplant populations

BACKGROUND

In adult transplant (Tx) populations, exercise rehabilitation strategies may improve sarcopenia components (muscle mass [MM], strength [MS], and physical performance [PP]). Limited data are available regarding exercise rehabilitation therapy in pediatric Tx populations.

METHODS

The purpose of this review is to critically evaluate the feasibility and impact of exercise programs (EP) that include resistance exercise (RE) on markers of sarcopenia in pediatric Tx populations. Literature searches in SCOPUS and WEB OF SCIENCE were conducted to identify studies applying EP with a RE component in pediatric populations in the Tx setting.

RESULTS

Twelve articles (2008-2022) met inclusion criteria. The exercise interventions varied in length (3 weeks-12 months), intensity (low to moderate), time pre/post Tx (0 days-5 years post Tx), age of participants (3-18 years), adherence (63%-94%), and methodologies to measure components of sarcopenia. No studies measured all three components of sarcopenia concurrently. Approximately, 60% of studies found positive effects on MS and PP. Only one pediatric study measured body composition, therefore, the effect of exercise programs with RE components on MM is unknown.

CONCLUSIONS

Exercise programs may be a beneficial treatment for sarcopenia in Tx populations, particularly in components of MS and PP. Studies measuring all three aspects of sarcopenia together in response to RE training in pediatrics remains an important gap. Studies that include body composition measurements in response to exercise are needed. Special considerations for the development of RE programs in pediatrics Tx populations are safety, supervision, engagement through family/peer involvement and incorporation of game/play-based elements.
