Effects of Combined Resistance and Aerobic Training on Arterial Stiffness in Postmenopausal Women: A Systematic Review

Physical Activity and Arterial Stiffness: A Narrative Review

Arterial stiffness is a significant predictor of cardiovascular disease and mortality. Physical activity (PA) has been extensively studied for its potential to reduce arterial stiffness, but the relationship between different types, durations, and intensities of PA and arterial stiffness remains a topic of ongoing research. Therefore, in this narrative review, we evaluated the current evidence focusing on the effect of PA on arterial stiffness and vascular health and discussed the known underlying physiological mechanisms. PA, irrespective of its intensity or pattern, is consistently associated with lower arterial stiffness. Aerobic exercise, particularly at higher intensities, is the most effective strategy for reducing arterial stiffness. These benefits are especially significant in populations with higher cardiovascular risk, such as those with type 2 diabetes mellitus and hypertension. Therefore, maintaining an active lifestyle into older age is crucial for vascular health and may contribute to healthy aging.

The therapeutic role of exercise training during menopause for reducing vascular disease

Menopause marks a major milestone in female reproductive ageing. It is characterized by the cessation of ovarian function and a concomitant decline in hormones such as oestradiol. Subsequently, females undergoing menopausal transition experience a progressive increase in cardiovascular and cerebrovascular disease risk. During menopause, reductions in nitric oxide (NO) bioavailability, endothelial dysfunction, increases in systemic inflammation, oxidative stress, and impaired vascular remodelling may contribute towards an accelerated decline in the function of cerebral and peripheral vascular systems. Historically, hormone therapy (HT) has been used as a means of managing vascular disease risk and reducing menopause-associated vasomotor symptoms such as hot flushes, though some studies suggest regular exercise has the potential to be a promising alternative. Regular aerobic exercise during early postmenopause may slow vascular decline by improving NO and oestradiol bioavailability, promoting positive vascular remodelling and lowering systemic inflammation. However, exercise-mediated improvements in markers of vascular function are not consistently observed in oestradiol-deficient postmenopausal women. Emerging evidence suggests that due to the greater oestradiol bioavailability during early postmenopause, vascular adaptations to exercise may be enhanced during this stage, as opposed to late postmenopause. Subsequently it may be important to begin regular exercise in the years preceding and immediately following the final menstrual period to slow the progression of vascular disease risk during perimenopause and beyond. The present review will provide a summary of our current understanding of how vascular function is affected during menopause and the role of regular aerobic and resistance exercise training in managing vascular disease risk.

Role of sex and training characteristics on exercise effects on cardiovascular aging: protocol for a systematic review with meta-analysis of randomized trials

BACKGROUND

Cardiovascular diseases remain a leading global cause of mortality worldwide especially in older adults. Although it is known that regular exercise reduces cardiovascular diseases incidence, its effects on specific cardiovascular aging parameters considering the influence of sex and different exercise designs are still not fully understood. Therefore, this systematic review and meta-analysis aims to evaluate the effects of different physical exercise protocols on age-related cardiovascular outcomes in older adults.

METHODS

This systematic review and meta-analysis will be reported in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Articles will be eligible if they are randomized controlled trials with a primary objective of evaluating the chronic effects of exercise interventions on cardiovascular aging parameters. Search strategy will be performed from the inception to September 30th, 2023, in the following electronic databases: MEDLINE (Ovid), SCOPUS (Elsevier), Embase, Sport Discus (EBSCO), Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science Core Collection (Clarivate Analytics). Data will be extracted and managed through Research Electronic Data Capture (REDCap) software. The Tool for the assEssment of Study qualiTy and reporting in EXercise (TESTEX) will be used to assess the methodological quality of included studies. Additionally, the quality of the findings will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) profiler. Meta-analysis based on the random-effects model will be performed (if deemed suitable, considering the methodological and clinical heterogeneity of the studies) to estimate the effects of exercise training on cardiovascular aging variables (i.e., cardiac output; arterial stiffness; stroke volume; endothelial function; and carotid intima-media thickness). Heterogeneity will be assessed with the I2 statistics, while the publication bias will be assessed based on Egger's test.

DISCUSSION

To the best of our knowledge, this will be the first systematic review and meta-analysis to investigate the impact of sex and training protocols on the cardiovascular aging parameters. Moreover, the findings of this systematic review and meta-analysis will provide evidence for health professionals in the management of elderly patients in order to optimize the exercise prescription to face the cardiovascular alterations related to the aging process, considering the effects of different protocols according to sex.

Short-duration dynamic power training with elastic bands combined with endurance training: a promising approach to hypertension management in older adults

Previous studies have investigated the effects of different combined training programs involving traditional resistance training and aerobic exercise on hemodynamic parameters and arterial stiffness in older adults. However, little is known about the impact of power training combined with endurance training on these variables in hypertensive older adults. Therefore, this study aimed to investigate the effects of dynamic power training with elastic bands combined with endurance training on arterial stiffness and hemodynamic parameters in hypertensive older adults. Twenty-six participants were randomly assigned to the control group (CG; n = 13) and the intervention group (n = 13). IG participants performed power training with elastic bands combined with endurance training twice a week for 8 weeks. Pulse pressure, central pulse pressure, pulse wave velocity, SBP, DBP, central SBP, and central DBP were assessed before and after 8 weeks using the triple pulse wave velocity method. Pulse pressure, central pulse pressure, pulse wave velocity, SBP, DBP, central SBP, and central DBP significantly improved after 8 weeks of intervention (P < 0.05). These findings indicate that power training with elastic bands combined with endurance training reduces arterial stiffness and significantly improves hemodynamic parameters in older adults diagnosed with grade 1 hypertension. In addition, underscores the potential of this approach as a promising strategy for the management of hypertension in older adults.

Effects of exercise programs on cardiorespiratory fitness and arterial stiffness on postmenopausal women: A systematic review study

BACKGROUND

Arterial stiffness is an important marker of cardiovascular disease, with a considerable increase in menopause. The impact of exercise, as a preventive measure, on controlling the progression of cardiovascular disease and arterial dysfunction in middle age remains under investigation.

OBJECTIVE

This systematic review aims to present the results of studies that examined the effects of different exercise programs (isolated, aerobic, and resistance or combined) on arterial stiffness and cardiorespiratory fitness in postmenopausal women.

METHODS

Based on PRISMA guidelines, B-On, BioMed, EBSCOhost, MEDLINE, ScienceOpen, PubMed, Science Direct, Scopus, Web of Science, Cochrane library and LILACS databases were searched using specific keywords.

RESULTS

A final total of 13 manuscripts were included in the qualitative synthesis, involving 700 participants. Four studies used only cardiorespiratory exercise, three only resistance, taekwondo class or flexibility exercise, and six combined exercise programs. Most interventions ranged from 3 to 5 days per week. Carotid-femoral pulse wave velocity showed improvements between 0.22 m/s and 1.56 m/s. In addition, one study showed an improvement of 4.4 ml/kg/min in maximal oxygen consumption. In 7 studies, participation in exercise programs improved arterial stiffness.

CONCLUSIONS

Combined exercise (aerobic and resistance exercise) and aerobic exercise alone (swimming) improve cardiorespiratory fitness and arterial stiffness in postmenopausal women, particularly pulse wave velocity. The combined exercise program is the most effective, promoting improvements of up to -2.6 m/s in pulse wave velocity in this climacteric phase.

Understanding of and clinical approach to cardiometabolic transition at the menopause

Cardiovascular disease (CVD) represents the leading cause of death and accounts for almost 50% of all deaths in women worldwide. The menopausal transition is associated with central body fat accumulation, a decrease in energy expenditure, weight gain, insulin resistance and a pro-atherogenic lipid profile. Moreover, menopause is independently associated with an adverse effect on functional and structural indices of subclinical atherosclerosis. Women with premature ovarian insufficiency have heightened CVD risk compared to women of natural age at menopause. Furthermore, women with severe menopausal symptoms may have a more adverse cardiometabolic profile than those without symptoms. We reviewed the latest evidence on the cardiovascular management of perimenopausal or postmenopausal women. Clinicians should aim for cardiovascular risk stratification, followed by dietary and lifestyle advice as required based on individual needs. The medical management of cardiometabolic risk factors at midlife should always be individualized, focusing on hypertension, diabetes and dyslipidemia. Menopausal hormone therapy, when prescribed for the management of bothersome menopausal symptoms or for the prevention of osteoporosis, has also a beneficial effect on cardiometabolic risk factors. This narrative review aims to summarize the cardiometabolic alternations occurring during the menopausal transition and to outline the appropriate prevention strategies to prevent future cardiovascular adverse outcomes.

Reimagining the Value of Brachial-Ankle Pulse Wave Velocity as a Biomarker of Cardiovascular Disease Risk-A Call to Action on Behalf of VascAgeNet

This review critiques the literature supporting clinical assessment and management of cardiovascular disease and cardiovascular disease risk stratification with brachial-ankle pulse wave velocity (baPWV). First, we outline what baPWV actually measures-arterial stiffness of both large central elastic arteries and medium-sized muscular peripheral arteries of the lower limb. Second, we argue that baPWV is not a surrogate for carotid-femoral pulse wave velocity. While both measures are dependent on the properties of the aorta, baPWV is also strongly dependent on the muscular arteries of the lower extremities. Increased lower-extremity arterial stiffness amplifies and hastens wave reflections at the level of the aorta, widens pulse pressure, increases afterload, and reduces coronary perfusion. Third, we used an established evaluation framework to identify the value of baPWV as an independent vascular biomarker. There is sufficient evidence to support (1) proof of concept; (2) prospective validation; (3) incremental value; and (4) clinical utility. However, there is limited or no evidence to support (5) clinical outcomes; (6) cost-effectiveness; (8) methodological consensus; or (9) reference values. Fourth, we address future research requirements. The majority of the evaluation criteria, (1) proof of concept, (2) prospective validation, (3) incremental value, (4) clinical utility and (9) reference values, can be supported using existing cohort datasets, whereas the (5) clinical outcomes and (6) cost-effectiveness criteria require prospective investigation. The (8) methodological consensus criteria will require an expert consensus statement. Finally, we finish this review by providing an example of a future clinical practice model.

Threshold values of brachial cuff-measured arterial stiffness indices determined by comparisons with the brachial-ankle pulse wave velocity: a cross-sectional study in the Chinese population

Background

Arterial Velocity-pulse Index (AVI) and Arterial Pressure-volume Index (API), measured by a brachial cuff, have been demonstrated to be indicative of arterial stiffness and correlated with the risk of cardiovascular events. However, the threshold values of AVI and API for screening increased arterial stiffness in the general population are yet to be established.

Methods

The study involved 860 subjects who underwent general physical examinations (M/F = 422/438, age 53.4 ± 12.7 years) and were considered to represent the general population in China. In addition to the measurements of AVI, API and brachial-ankle pulse wave velocity (baPWV), demographic information, arterial blood pressures, and data from blood and urine tests were collected. The threshold values of AVI and API were determined by receiver operating characteristic (ROC) analyses and covariate-adjusted ROC (AROC) analyses against baPWV, whose threshold for diagnosing high arterial stiffness was set at 18 m/s. Additional statistical analyses were performed to examine the correlations among AVI, API and baPWV and their correlations with other bio-indices.

Results

The area under the curve (AUC) values in ROC analysis for the diagnosis with AVI/API were 0.745/0.819, 0.788/0.837, and 0.772/0.825 (95% CI) in males, females, and all subjects, respectively. Setting the threshold values of AVI and API to 21 and 27 resulted in optimal diagnosis performance in the total cohort, whereas the threshold values should be increased to 24 and 29, respectively, in order to improve the accuracy of diagnosis in the female group. The AROC analyses revealed that the threshold values of AVI and API increased markedly with age and pulse pressure (PP), respectively.

Conclusions

With appropriate threshold values, AVI and API can be used to perform preliminary screening for individuals with increased arterial stiffness in the general population. On the other hand, the results of the AROC analyses imply that using threshold values adjusted for confounding factors may facilitate the refinement of diagnosis. Given the fact that the study is a cross-sectional one carried out in a single center, future multi-center or follow-up studies are required to further confirm the findings or examine the value of the threshold values for predicting cardiovascular events.

Combinatory Effects of Training and Nutritive Administration of Carbohydrates and Protein via Food on Strength in Postmenopausal Women, and Old Men and Women

The age-related loss of muscle mass promotes many impairments. Training and protein supplementation are suggested to prevent muscle wasting, but recommendations for all populations are not based on scientific evidence. This study combines protein/carbohydrate supplementation (PCS) and training for seniors and postmenopausal women. Project A: 51 postmenopausal women (PMW, 57.3 ± 3.0 years old) underwent health-oriented training (12 weeks, moderate-strength training + moderate-endurance training). The intervention group (IG) additionally received 110 g sour milk cheese (SMC) and toast. Project B: 25 women and 6 men (65.9 ± 4.9 years old) performed intense sling training (12 weeks). The IG additionally received 110 g SMC, toast, and buttermilk. Strength was tested before and after in both studies. Project A: there was significant increase in strength, no additional effect of PCS, and a reduction in body fat in the controls. Project B: there was significant increase in strength, significant additional effects of PCS for trunk strength, and a significant reduction in body weight. Combining training and PCS may counteract strength loss. Combined endurance/resistance training is recommended to PMW for whom the benefits of PCS are restricted. Aged subjects may benefit from PCS when training intensely, but these benefits may be strongly individual.

Effect of Exercise on Vascular Function and Blood Lipids in Postmenopausal Women: A Systematic Review and Network Meta-Analysis

This study aimed to compare and rank the effectiveness of aerobic exercise (AE), resistance training (RT), combined training (CT), and water exercise (WE) on vascular function and blood lipids in postmenopausal women using a network meta-analysis (NMA).

METHODS

We searched the PubMed, Cochrane, Embase, Web of Science, and EBSCO (SPORTDiscus) databases to identify randomized controlled trials investigating the effects of exercise on vascular function and blood lipids in postmenopausal women. The retrieval period was from inception to March 2022. Two reviewers independently screened the retrieved articles, extracted pertinent data, and assessed the risk of bias of the included studies.

RESULTS

A total of 38 studies involving 1407 patients were included in this study. The results of the NMA indicated that WE had the greatest effect on systolic blood pressure (SBP) (surface under the cumulative ranking [SUCRA] = 84.9) and total cholesterol (TC) (SUCRA = 93.1); CT had the greatest effect on triglycerides (TG) (SUCRA = 96.2), high-density lipoprotein cholesterol (HDL-C) (SUCRA = 94.8), and diastolic blood pressure (DBP) (SUCRA = 91.1); RT had the greatest effect on low-density lipoprotein cholesterol (LDL-C) (SUCRA = 79.4).

CONCLUSION

The results suggest that exercise can effectively improve the PWV, SBP, and DBP and the levels of TC, TG, and LDL-C in postmenopausal women. WE had the best effect on improving TC and SBP. CT had the best effect on improving TG, HDL-C, and DBP. To improve LDL-C, RT can achieve a good effect. Considering the limitations of NMA, more RCTS need to be performed in the future to provide more direct evidence of the effectiveness of various exercise interventions on vascular health in postmenopausal women.

Redox Status of Postmenopausal Women with Single or Multiple Cardiometabolic Diseases Has a Similar Response to Mat Pilates Training

Postmenopausal women have a high prevalence of cardiometabolic diseases and that may associate with higher oxidative stress. Exercise can contribute to the treatment of such diseases, but some modalities, such as Mat Pilates, need to be further studied in terms of their physiological responses. Our aim was to investigate the effects of 12 weeks of Mat Pilates on redox status in postmenopausal women with one or multiple comorbidities of cardiometabolic diseases. Forty-four postmenopausal women were divided into two groups: SINGLE, composed of women with one cardiometabolic disease (n = 20) and MULT, with multimorbidity (n = 24). Mat Pilates training was conducted three times a week for 12 weeks, and each session lasted 50 min. Plasma samples were collected before and after training to analyze the following redox markers: superoxide dismutase, catalase, glutathione peroxidase, total antioxidant capacity due to ferric-reducing antioxidant power (FRAP), reduced glutathione (GSH), uric acid, and carbonyl protein. ANCOVA showed interaction effects in FRAP (p = 0.014). Both groups had reduced levels of catalase (p = 0.240) and GSH (p = 0.309), and increased levels of carbonyl protein (p = 0.053) after intervention. In conclusion, the redox status of postmenopausal women shows no changes mediated by Mat Pilates training between SINGLE and MULT, except for greater reductions of FRAP in SINGLE.

Research on risk factors of ischemic cerebrovascular disease in postmenopausal women based on the social-ecological model

Objective

Based on the social-ecological model, this study aimed to comprehensively explore factors affecting the risk of ischemic cerebrovascular disease (ICVD) in postmenopausal women to provide theoretical bases for further prevention and intervention for postmenopausal women.

Methods

Postmenopausal women who underwent medical examinations in one health-checkup agency in Tianjin from May 2015 to October 2015 were enrolled in this study. The ICVD 10-year Risk Assesment Form developed by the research team of the National "Tenth Five-Year Plan" research project was used to assess the factors affecting the risk of ICVD. Based on the social-ecological model, multiple types of scales, including physical activities, depression, Type D personality, social supports, and environment score, were used to comprehensively explore the factors associated with ICVD in postmenopausal women.

Results

300 valid questionnaires were obtained, with an effective rate of 92.0%. The subjects aged 44–74 years, with the average age of 62.06 ± 7.09 years. Among them, 58.67% of the subjects only obtained high-school diploma, 32.67% obtained college or university diploma, 90.33% were retirees, 95.33% were married, 92.33% experienced the natural menopause, 93.33% lived in urban or suburban areas, and 1.00% had a history of breast cancer. Multivariate logistic regression analysis suggested that monthly income (¥), parity, exposure to second-hand or third-hand smoke, easy access to healthy food, physical activities, depression, Type D personality, social support and environmental factors were associated with the risk of ICVD in postmenopausal women (P < 0.05). Among them, easy access to healthy food (OR = 0.242), social support (OR = 0.861) and environmental factors (OR = 0.866) were protective factors from ICVD. OR < 1 indicates that the exposure factor is negatively correlated with the disease, and the exposure factor has a protective effect on preventing the occurrence of the disease. Parity (OR = 3.795), exposure to second-hand or third-hand smoke (OR = 2.886), depression (OR = 1.193), and Type D personality (OR = 1.148) were risk factors of ICVD. OR > 1 means that the exposure factor is positively correlated with the disease, and the exposure factor increases the risk of disease occurrence.

Conclusions

For postmenopausal women, in the future, in addition to prevention and management of the conventional risks, the conditions of their mentality and social support should be paid attention to, at the same time, and if they can, try to choose a good community environment to live in, which could better reduce the incidence and mortality of ICVD in postmenopausal women.

Sex Differences in Biological Systems and the Conundrum of Menopause: Potential Commonalities in Post-Menopausal Disease Mechanisms

Sex-specific differences in biology and physiology likely start at the time of conception and progress and mature during the pre-puberty time frame and then during the transitions accompanying puberty. These sex differences are impacted by both genetics and epigenetic alterations during the maturation process, likely for the purpose of preparing for successful reproduction. For females, later in life (~45-50) they undergo another transition leading to a loss of ovarian hormone production at menopause. The reasons for menopause are not clear, but for a subset of females, menopause is accompanied by an increased risk of a number of diseases or conditions that impact a variety of tissues. Most research has mainly focused on the target cells in each of the affected tissues rather than pursue the alternative option that there may be commonalities in the development of these post-menopausal conditions in addition to influences on specific target cells. This review will address some of the potential commonalities presented by an integration of the literature regarding tissue-specific aspects of these post-menopausal conditions and data presented by space flight/microgravity (a condition not anticipated by evolution) that could implicate a loss of a regulatory function of the microvasculature in the risk attached to the affected tissues. Thus, the loss of the integration of the paracrine relationships between endothelial cells of the microvasculature of the tissues affected in the post-menopausal environment could contribute to the risk for post-menopausal diseases/conditions. The validation of this concept could lead to new approaches for interventions to treat post-menopausal conditions, as well as provide new understanding regarding sex-specific biological regulation.

Women's perception about hydrotherapy in postmenopause: a qualitative study

Abstract Introduction: The transition from reproductive to post-reproductive life is part of the female life cycle that impacts well-being, with menopause as a significant milestone. Regular physical activity should be encouraged to mitigate the symptoms of menopause and prevent age-related problems. Hydrotherapy is one such alternative, since immersion in heated water facilitates exercises that would be difficult to perform on land. Objective: Assess women’s perception about the effect of hydrotherapy on the signs and symptoms of postmenopause. Methods: A qualitative study in which participants underwent 48 hydrotherapy sessions and answered a semistructured interview. Results: The participants were eight women, aged 55.75 ± 8.55 years, menopausal for 8.5 ± 7.98 years, with vasomotor symptoms (100%), mood swings (87.5%), sleep disorders (87.5%), vaginal dryness (62.5%), low sex drive (62.5%) and chronic pain (100%). Conclusion: Women’s perception about the effects of hydrotherapy on the signs and symptoms of postmenopause include less pain and muscle tension, a decline in the signs and symptoms, better quality of life and sexual pleasure, and an improvement in biopsychosocial factors such as anxiety and stress through better social interaction.

Percepção de mulheres sobre a fisioterapia aquática na pós-menopausa: um estudo qualitativo

Resumo Introdução: A transição da vida reprodutiva para a pós-reprodutiva é considerada um dos ciclos da vida feminina que gera impactos no bem-estar da mulher, sendo a menopausa o marco significativo. A prática regular de atividade física deve ser encorajada para reduzir os sintomas da menopausa e prevenir alterações associadas ao envelhecimento. Assim, a fisioterapia aquática é uma opção de atividade física, pois a imersão em água aquecida possibilita a realização de exercícios que seriam difíceis de serem executados no solo. Objetivo: Evidenciar a percepção de mulheres sobre a fisioterapia aquática nos sinais e sintomas da pós-menopausa. Métodos: Trata-se de um estudo qualitativo, com participantes que realizaram 48 sessões de fisioterapia aquática e responderam a uma entrevista semiestruturada. Resultados: Participaram do estudo oito mulheres, 55,75 ± 8,55 anos, menopausadas há 8,5 ± 7,98 anos, com referência de alterações vasomotoras (100%), do humor (87,5%), do sono (87,5%), secura vaginal (62,5%), diminuição da libido (62,5%) e dor crônica (100%). Conclusão: A percepção das mulheres sobre os efeitos da fisioterapia aquática nos sinais e sintomas da menopausa aponta para uma diminuição do quadro álgico e da tensão muscular, diminuição dos sinais e sintomas da pós-menopausa, melhora da qualidade do sono, bem como do prazer sexual, e melhora nos fatores biopsicossociais como ansiedade e estresse, através da melhora da interação social.
