Motives and barriers to initiation and sustained exercise adherence in a fitness club setting-A one-year follow-up study

The ASSIST trial: Acute effects of manipulating strength exercise volume on insulin sensitivity in obese adults: A protocol for a randomized controlled, crossover, clinical trial

Type 2 diabetes mellitus is a disease in which insulin action is impaired, and an acute bout of strength exercise can improve insulin sensitivity. Current guidelines for strength exercise prescription suggest that 8 to 30 sets could be performed, although it is not known how variations in exercise volume impact insulin sensitivity. Additionally, this means an almost 4-fold difference in time commitment, which might directly impact an individual's motivation and perceived capacity to exercise. This study will assess the acute effects of high- and low-volume strength exercise sessions on insulin sensitivity. After being thoroughly familiarized, 14 obese individuals of both sexes (>40 year old) will undergo 3 random experimental sessions, with a minimum 4-day washout period between them: a high-volume session (7 exercises, 3 sets per exercise, 21 total sets); a low-volume session (7 exercises, 1 set per exercise, 7 total sets); and a control session, where no exercise will be performed. Psychological assessments (feeling, enjoyment, and self-efficacy) will be performed after the sessions. All sessions will be held at night, and the next morning, an oral glucose tolerance test will be performed in a local laboratory, from which indexes of insulin sensitivity will be derived. We believe this study will aid in strength exercise prescription for individuals who claim not to have time to exercise or who perceive high-volume strength exercise intimidating to adhere to. This trial was prospectively registered (ReBEC #RBR-3vj5dc5 https://ensaiosclinicos.gov.br/rg/RBR-3vj5dc5).

Effects of acute and chronic stair-climbing exercise on metabolic health: A systematic review

Stair climbing exercise (SE) provides a feasible approach to elevate physical activity, but the effects on metabolic health are unclear. We systematically reviewed the currently available evidence on the effects of SE on fasting and postprandial glycaemia and lipidaemia. Studies were included if they investigated the effects of acute or chronic (at least 2 weeks) SE on fasting and/or postprandial glycaemic (insulin and glucose) and lipidaemic (triacylglycerols and non-esterified fatty acids) responses in healthy, prediabetic or type 2 diabetic adult populations. PubMed, Web of Science and Scopus were searched for eligible studies until July 2022. A total of 25 studies (14 acute and 11 chronic) were eligible for review. Acute bout(s) of SE can reduce postprandial glycaemia in individuals with prediabetes and type 2 diabetes (8 of 9 studies), but not in normoglycemic individuals. The effects of acute SE on postprandial lipidaemic responses and SE training on both fasting and postprandial glycaemia/lipidaemia were unclear. Acute SE may reduce postprandial glucose concentrations in people with impaired glycaemic control, but high-quality studies are needed. More studies are needed to determine the effect of chronic SE training on postprandial glucose and lipid responses, and the acute effects of SE on lipid responses.

Implementing Meta-Session Autoregulation Strategies for Exercise - A Scoping Review

Meta-session autoregulation, a person-adaptive form of exercise prescription that adjusts training variables according to daily fluctuations in performance considering an individual's daily fitness, fatigue, and readiness-to-exercise is commonly used in sports-related training and may be beneficial for non-athlete populations to promote exercise adherence. To guide refinement of meta-session autoregulation, it is crucial to examine the existing literature and synthesize how these procedures have been practically implemented. Following PRIMSA guidelines a scoping review of two databases was conducted from August 2021 to September 2021 to identify and summarize the selected measures of readiness-to-exercise and decision-making processes used to match workload to participants in meta-session autoregulatory strategies, while also evaluating the methodological quality of existing study designs using a validated checklist. Eleven studies reported utilizing a form of meta-session autoregulation for exercise. Primary findings include: (i) readiness-to-exercise measures have been divided into either objective or subjective measures, (ii) measures of subjective readiness measures lacked evidence of validity, and (iii) fidelity to autoregulatory strategies was not reported. Results of the risk of bias assessment indicated that 45% of the studies had a poor-quality score. Existing implementations of meta-session autoregulation are not directly translatable for use in health promotion and disease prevention settings. Considerable refinement research is required to optimize this person-adaptive strategy prior to estimating effects related to exercise adherence and/or health and fitness outcomes. Based on the methodological deficits uncovered, researchers implementing autoregulation strategies would benefit reviewing existing models and frameworks created to guide behavioral intervention development.

Energy Expenditure, Intensity, and Perceived Effort in Recreational Functional Training

Background: Functional training (FT) has become popular and seems to provoke health benefits. However, there are unsubstantiated claims regarding energy expenditure (EE) vs. weight-loss and cardiorespiratory improvements linked to FT. Objective: This study quantified the EE and intensity during FT performed in a conventional fitness center. Additionally, data of FT and moderate continuous walking (WLK) were compared. Methods: Healthy individuals with no previous experience with FT [n = 25, 11 males/14 females, 38.8 ± 9.3 years; 73.9 ± 13.8 Kg; 168.5 ± 8.5 cm; 26.0 ± 4.5 Kg/m2; 16 overweight (BMI >25 Kg/m2)] performed three FT sessions interspersed with 48 h (two familiarization, one assessment). The circuit included 4 rounds of 12 exercises performed at all-out intensity for 20 s with 1-min intervals between rounds. WLK was performed for 25 min with intensity corresponding to scores 3-5 on Borg CR-10 Scale. Outcomes were EE (kcal), movement counts estimated by triaxial accelerometry, heart rate reserve (%HRR), and rate of perceived exertion (RPE). Results: On average, FT sessions lasted 24 min and EE ranged between 124 and 292 kcal (188 ± 41 kcal), corresponding to 5-8 METs (6.1 ± 0.6 METs), and 70-80%HRR (74 ± 8%). Accelerometry (counts/min) showed that vigorous predominated over moderate intensity during FT and WLK (p = .01), with similar EE. The relative intensity and RPE were higher in FT vs. WLK (74% vs. 55%HRR and Borg 5-8 vs. 3-5, respectively; p < .0001). Conclusion: FT and WLK elicited EE consistent with recommendations to reduce cardiovascular disease risk, but only FT achieved relative intensities compatible with cardiorespiratory improvement. FT should be considered an option in health-oriented exercise programs for the general population.

Use of a Home-Based, Commercial Exercise Platform to Remotely Monitor Aerobic Exercise Adherence and Intensity in People With Parkinson Disease

OBJECTIVE

Physical therapists are well-positioned to prescribe exercise outside of a clinical setting to promote positive health behaviors in people with Parkinson disease (PD). Traditionally, a barrier to precise exercise prescription has been reliance on participant self-reported exercise adherence and intensity. Home-based, commercially available exercise platforms offer an opportunity to remotely monitor exercise behavior and facilitate adherence based on objective performance metrics. The primary aim of this project was to characterize the feasibility and processes of remote aerobic exercise data monitoring from a home-based, commercially available platform in individuals participating in the 12-month Cyclical Lower Extremity Exercise for PD II (CYCLE-II) randomized clinical trial. Secondary aims focused on using exercise behavior to classify the cohort into exercise archetypes and describing a shared decision-making process to facilitate exercise adherence.

METHODS

Data from each exercise session were extracted, visualized, and filtered to ensure ride integrity. Weekly exercise frequency was used to determine exercise archetypes: Adherent (2-4 exercise sessions per week), Over-adherent (>4 exercise sessions per week), and Under-adherent (<2 exercise sessions per week).

RESULTS

A total of 123 people with PD completed 22,000+ exercise sessions. Analysis of exercise frequency indicated that 79% of participants were adherent; 8% were over-adherent; and 13% were under-adherent. Three case reports illustrate how shared decision-making with the use of exercise performance data points guided exercise prescription.

CONCLUSIONS

The number of exercise sessions and completeness of the data indicate that people with PD were able to utilize a commercial, home-based exercise platform to successfully engage in long-term aerobic exercise. Physical therapists can use objective data as a part of a shared decision-making process to facilitate exercise adherence.

IMPACT

Commercially available exercise platforms offer a unique approach for physical therapists to monitor exercise behavior outside of a clinical setting. The methods used in this project can serve as a roadmap to utilizing data from consumer-based platforms.

Exploring exercise adherence and quality of life among veteran, novice, and dropout trainees

Introduction

The purpose of this study was to identify and reveal the different contexts, variables, and factors that may influence adherence to physical activity among veteran, novice, and dropout trainees, such as the frequency of the weekly training units, the trainees preferred type of exercise, the purpose of the physical activity, and the relationship between support and supervision by fitness instructors and professionals. This study also examined the relationships between trainees, seniority and the strength of the habit and adherence to physical activity, the effects of personal variables such as age and gender on adherence to physical activity, and how the seniority and adherence of trainees may affect their quality of life.

Methods

A total of 460 participants drawn from the broader Israeli exercise community, which encompasses a diverse range of individuals within the general adult population, were engaged in this study. These participants included seasoned exercisers, individuals who had recently initiated exercise routines, and those who had previously engaged in physical activity. Each participant completed a comprehensive set of questionnaires, including the Self-Report Habit Index, the Exercise Adherence Rating Scale, and the World Health Organization (WHO) Quality of Life Scale. In addition to the questionnaire responses, demographic data and inquiries concerning their physical activity were also collected.

Results

The results show that the average frequency of the weekly training units of veteran trainees was significantly higher than that of novice trainees: 3.95 and 2.93, respectively (p < 0.0001). We found no significant differences between novice and veteran trainees regarding their training goal preferences (p = 0.07). Veteran trainees who had been in training for more than a year appeared to have higher self-efficacy since 31.16% reported receiving no supervision compared to 16.67% among novice trainees. In addition, people over 45 appear to have more health-related goals compared to their younger counterparts (p < 0.001). The quality of life scores of the trainees was related to their seniority in physical training, but only by a small magnitude (R2 = 0.06), p < .001). Those who trained in resistance training showed the greatest rate of adherence in relation to flexibility and aerobic training (p < 0.001), and women preferred more body toning and had more weight loss goals than men (p < 0.001).

Discussion

The results indicate that there are central and important factors that may affect adherence to physical activity, and that all these aspects must be taken into account when planning a training program or when there is a desire to maintain or increase adherence to physical activity. The research findings indicate that the main factors that can influence adherence to physical activity are identifying and increasing the trainee's self-efficacy, maintaining weekly training units with sufficient frequency to form a habit and incorporating resistance training into the training regime, as resistance training has shown high levels of adherence. Moreover, it seems that people with different degrees of experience in physical training have distinct and varied training goals, and there is no one goal that fits all. In addition, specific factors such as age and gender must also be taken into account, because the age and gender of the trainees may significantly affect the goals of physical training.

Global Self-Esteem, Body Composition, and Physical Activity in Polish University Students

Global self-esteem is a psychological concept that refers to the overall assessment of oneself as a person of value. Body composition is measured by indices such as BMI, BF, and LBM, which have implications for health and self-esteem. Physical activity is associated with numerous health and self-esteem benefits. The purpose of this study focuses on assessing the relationship between global self-esteem, body composition, and physical activity among Polish students. The study was conducted on a group of 305 students between the ages of 19 and 26. The participants were divided into groups according to their level of physical activity. The SES scale by M. Rosenberg assessed the subjects' global self-esteem. The results showed a negative correlation between body weight and BMI and global self-esteem, that is, the higher the body weight, the lower the self-esteem. On the other hand, higher levels of physical activity were associated with higher global self-esteem. The study suggests that maintaining healthy physical activity and body composition can help improve global self-esteem. The study highlights the importance of physical activity for mental health and self-esteem. It is worth encouraging and promoting physical activity among students to support an individual's physical and emotional health. Ultimately, this study may have implications for health policy, education, and intervention for students to emphasize the importance of physical activity for self-esteem and overall health.

How Do Fitness Club Members Differentiate in Background Characteristics, Exercise Motivation, and Social Support? A Cross-Sectional Study

Fitness clubs are one of the largest exercise arenas worldwide. Still, membership withdrawal and exercise dropout rates are 40-65% in the first six months. One important approach to retaining members may be to create an environment that feels inclusive, and clusters members with mutual needs and interests. Increased knowledge in this field can provide valuable information that leads to more effective exercise promotion strategies and better retention rates, important to the long-term success of the gym and public health. Thus, we aimed to compare background factors, motivation, and social support between members of multipurpose (wide range of exercise concepts/facilities, middle to high membership fee), fitness-only (low membership fee), and boutique (one or two specialized exercise concepts, high membership fee) fitness clubs. A total of 232 members from multipurpose (n = 107), fitness-only (n = 52), and boutique gyms (n = 73) were recruited for this cross-sectional study. Data included background variables (age, gender, body weight and height, smoking, total household income, occupation, education, and general health), exercise behaviour, exercise motivation, and social support. A one-way between-group ANOVA with Bonferroni correction or a chi-square test was used as appropriate. Multipurpose and fitness-only members were older (mean diff: 9.1 years, p = <0.001) and exercised less (mean diff: 1-1.2 sessions/week, p = <0.001) than members from boutique clubs. Compared with multipurpose and fitness-only members, members from boutique clubs reported the highest autonomous motivation (intrinsic regulation: mean diff: 0.3, p = 0.030), and perceived greater social support from family/friends (mean diff: 6.4 to 6.6, p = <0.001). Boutique members were younger, exercised more, and reported higher autonomous motivation and social support than multipurpose and fitness-only members. Our results suggest that exercise enjoyment and a social community, the "philosophy" of boutique gyms, may be important for regular exercise.

Daily Physical Activity: Associations With Memory and Affect

PURPOSE

Little is known about effects of moderate to vigorous physical activity (MVPA) and resistance training on daily variations in memory and affect. This study examined the relationship of MVPA and resistance training to memory and affect in daily life.

DESIGN

Short-term longitudinal 7-day diary.

SETTING

Northeast; primarily Boston-area communities.

SAMPLE

Adults aged 25 to 94.

MEASURES

For seven days, MVPA was assessed with an Actigraph. and resistance training was self-reported. Each evening, memory failures, positive and negative affect were recorded in a written diary and objective memory performance was assessed by telephone.

ANALYSIS

Multilevel linear regression analyses examined the between and within person associations of MVPA and resistance training with memory performance, memory failures, and affect.

RESULTS

Those who engaged in more MVPA had better memory performance across the week (b = 0.0163, SE = 0.0076, f2 = 0.004, p = 0.033). Participants reported higher levels of positive affect on days in which they spent more time in MVPA than usual (b = 0.003, SE = 0.001, f2 = 0.144, p < .001) and on days they engaged in resistance training (b = 0.1547, SE = 0.079, f2 = 0.007; p = 0.049).

CONCLUSIONS

Those who spent more time in MVPA had better memory performance, and on days with greater than usual MVPA time and resistance training, affect was more positive than on days with less activity. Implications for motivating physical exercise are considered.

Influence of Sports Participation on the Behaviors of Customers of Sports Services: Linear and Qualitative Comparative Analysis Models

Sports services have become an important enclave for our society. Due to its complete sports offer, customers can perform physical activity that helps them to improve their health and well-being. In fitness centers, managers try to know what their customers are looking for in order to create more personalized experiences, as well as to improve their health. This study seeks to understand the influence that sports frequency has on the future behavior of users of a sports center, using two complementary methodologies. A sample of 383 users of a private sports center was used. The two complementary methodologies used were linear models and comparative qualitative analysis, based on the combination of sets. The results show how sports frequency influences the process of creating users' future behaviors. Considering that none of the variables are necessary, it is observed that perceived value has a significant influence on users' future behaviors. The use of two complementary methodologies provides a more complete understanding, which helps sports managers to plan and manage effectively to ensure user satisfaction and loyalty. In addition, facilities can incentivize customers through loyalty programs and promotions to maintain their engagement, as well as healthy styles to encourage service recommendations.

Molecular predictors of resistance training outcomes in young untrained female adults

We sought to determine if the myofibrillar protein synthetic (MyoPS) response to a naïve resistance exercise (RE) bout, or chronic changes in satellite cell number and muscle ribosome content, were associated with hypertrophic outcomes in females or differed in those who classified as higher (HR) or lower (LR) responders to resistance training (RT). Thirty-four untrained college-aged females (23.4 ± 3.4 kg/m2) completed a 10-wk RT protocol (twice weekly). Body composition and leg imaging assessments, a right leg vastus lateralis biopsy, and strength testing occurred before and following the intervention. A composite score, which included changes in whole body lean/soft tissue mass (LSTM), vastus lateralis (VL) muscle cross-sectional area (mCSA), midthigh mCSA, and deadlift strength, was used to delineate upper and lower HR (n = 8) and LR (n = 8) quartiles. In all participants, training significantly (P < 0.05) increased LSTM, VL mCSA, midthigh mCSA, deadlift strength, mean muscle fiber cross-sectional area, satellite cell abundance, and myonuclear number. Increases in LSTM (P < 0.001), VL mCSA (P < 0.001), midthigh mCSA (P < 0.001), and deadlift strength (P = 0.001) were greater in HR vs. LR. The first-bout 24-hour MyoPS response was similar between HR and LR (P = 0.367). While no significant responder × time interaction existed for muscle total RNA concentrations (i.e., ribosome content) (P = 0.888), satellite cell abundance increased in HR (P = 0.026) but not LR (P = 0.628). Pretraining LSTM (P = 0.010), VL mCSA (P = 0.028), and midthigh mCSA (P < 0.001) were also greater in HR vs. LR. Female participants with an enhanced satellite cell response to RT, and more muscle mass before RT, exhibited favorable resistance training adaptations.NEW & NOTEWORTHY This study continues to delineate muscle biology differences between lower and higher responders to resistance training and is unique in that a female population was interrogated. As has been reported in prior studies, increases in satellite cell numbers are related to positive responses to resistance training. Satellite cell responsivity, rather than changes in muscle ribosome content per milligrams of tissue, may be a more important factor in delineating resistance-training responses in women.

Global and appearance-contingent self-esteem: Associations with health and attractiveness exercise reasons

Whilst some individuals exercise for health-related reasons, others appear to exercise to bolster physical attractiveness. For the latter, this is often attributed to dissatisfaction with appearance. Few studies, however, have explored if differences in self-esteem may relate to diverse exercise reasons. The present study investigated whether global self-esteem, appearance-contingent self-worth, and appearance satisfaction may be differentially associated with health and attractiveness exercise reasons. It was further sought to explore whether these relations coincided with different motivational regulations. Adults from the east midlands of the United Kingdom (N = 209; 75% female, 25% male; mean age = 29.77 years) completed measures relating to their global and appearance-contingent self-esteem, appearance satisfaction, exercise intentions, and motivations. Structural equation modelling revealed that global self-esteem was positively associated with appearance satisfaction and health reasons for exercise, whereas appearance-contingent self-esteem related to lower appearance satisfaction and attractiveness reasons. Appearance satisfaction had no association with either exercise reason but was associated with intrinsic motivation and lower controlled exercise motivations. Health exercise reasons were positively associated with intrinsic, identified, and introjected motivation, whereas attractiveness reasons were exclusively related to external motivation. The findings highlight the conceptual importance of differentiating the level and contingency of exercisers' self-esteem. The findings may also have substantive value for exercise practitioners in understanding different reasons for exercise.

Adaptive Goal Processes and Underlying Motives That Sustain Mental Wellbeing and New Year Exercise Resolutions

Exercise resolutions are the most common goals people set each New Year. However, research has rarely examined adaptive goal processes and motives that may maintain wellbeing and resolution pursuit. We therefore investigated if (1) personal goal flexibility and tenacity maintain mental wellbeing and adherence to New Year exercise resolutions and if (2) underlying intrinsic and extrinsic motives maintain wellbeing and sustained exercise resolution adherence. A community sample (N = 297) completed an online longitudinal study. At baseline, participants listed their most important exercise-related New Year resolution. Participants then completed measures to assess goal flexibility and tenacity, resolution motives, and mental wellbeing at baseline. At three follow-up surveys over a two-month period, participants completed self-report measures of wellbeing and adherence to their exercise resolution. As predicted, goal flexibility and tenacity each independently predicted wellbeing across time. Counter to prediction, neither goal flexibility nor tenacity predicted sustained exercise adherence. Notably, underlying intrinsic motives (but not extrinsic motives) maintained mental wellbeing and exercise adherence across time. Our findings indicate that goal flexibility and tenacity are beneficial in maintaining mental wellbeing and that pursuing resolutions for internalised motives is beneficial for one's mental wellbeing and exercise adherence.

The effect of rhythmic movement on physical and cognitive functions among cognitively healthy older adults: A systematic review and meta-analysis

OBJECTIVE

To explore the effects of rhythmic movement interventions on the physical and cognitive functions among cognitively healthy older adults.

METHODS

We searched PubMed, Web of Science, Cochrane Library, EMBASE, CNKI, CBM, Wanfang Data, and VIP databases from inception to March 30, 2022. The inclusion criteria were: ① randomized controlled trials (RCTs); ② older adults (aged ≥ 60 years) without cognitive impairments or neurological or neurodegenerative diseases; ③ intervention: rhythmic movement (rhythmic exercise or physical activities performed to music); ④ outcomes: physical or cognitive function. Overall, 44 RCTs across 20 countries (n = 2752 participants) were included.

RESULTS

An association was found between rhythmic movement and improved physical function (mobility, cardiopulmonary endurance, muscle strength, flexibility, and balance), global cognitive function, and quality of life (QOL). The physical function outcomes suggested additional significant benefits when using control groups with no exercise than when using control groups with exercise. No significant improvement was found in executive function.

CONCLUSION

Regular rhythmic movement likely improves physical function, global cognitive function, and QOL in healthy older adults. The effect of rhythmic movement on the physical function in older adults is similar to that of routine exercise. Further studies on cognitive function of healthy older adults using larger samples of populations with more balanced sex ratios with long-term follow-up are particularly encouraged.

Hiking, indoor biking, and body liking: a cross-sectional study examining the link between physical activity arenas and adults' body appreciation

BACKGROUND

Body appreciation might serve as a protective factor for developing eating disorders and is associated with participation in physical activity. Less is known about whether various arenas for physical activity may be linked to body appreciation. Therefore, the current study sought to (1) identify potential associations between physical activity level and arenas for physical activity, connectedness with nature, self-compassion, and body appreciation in adults, and (2) explore physical activity level and arenas, connectedness with nature, and self-compassion as explanatory factors for body appreciation.

METHODS

A total of 360 adult Norwegian inhabitants (75% women, mean (SD) age 42.58 (12.30) yrs) responded to an online questionnaire. Instruments included the Body Appreciation Scale, the Connectedness with Nature Scale, and the Self-Compassion Scale.

RESULTS

The percentage of participants who engaged in various physical activity arenas were 98.5% for nature, 57.5% for fitness centers, and 43.0% for organized sports. Small, positive associations were found between body appreciation and the frequency of using fitness centers and nature as physical activity arenas. Self-compassion, connectedness with nature, and frequency of using fitness centers and nature as physical activity arenas explained 39% of the variance in body appreciation.

DISCUSSION

The importance of both fitness centers and nature as arenas for physical activity to explain body appreciation was surprising and might reflect different use of fitness centers among adults compared to younger age groups.

CONCLUSION

Physical activity at fitness centers and in nature were positively associated with body appreciation in adults. Self-compassion, connectedness with nature, and using fitness centers and nature as arenas for physical activity, were found to explain variation in body appreciation in adults.

The Coronavirus pandemic and closed fitness clubs negatively affected members exercise habits

Introduction

Due to the Coronavirus pandemic, politicians enacted directions to reduce social interactions, including lockdown of fitness clubs. We aimed to investigate how this changed exercise habits of Norwegian gym members.

Method

Based on survey data, men and women (≥18 years, n = 233, data collection from Aug. 2020 to Jan. 2021) were recruited to this study by an email-invitation from their fitness club chain or by Facebook advertisement. The participants reported on background variables (e.g., age, gender, total household income, occupation, and education), and exercise habits pre- and during social lockdown. Data were analyzed using independent or student t-test, chi-squared test, or McNemar's test, as appropriate.

Results

Home-based exercise (18.0 vs. 72.5%, p = <0.001), walking (49.8 vs. 65.2%, p = <0.001), and cycling (16.7 vs. 24.5%, p = 0.004) was more common during than pre-lockdown. Also, men (4.33 to 3.68 days/week, p =0.013) and women (4.20 to 3.79 days/week, p = 0.001) reported a lower exercise frequency, and a shorter duration. Exercise frequency was lower in those with a BMI ≥25 than in those with BMI <25 (3.95 vs. 4.48 days/week, p = <0.007) pre-lockdown. High exercise attendees (≥3 sessions/week, 66.5%) reported a smaller decrease in exercise frequency (mean change: 0.06 vs. 1.24 days/week, p = <0.001) and duration (>60 min. per session: 33.0 vs. 3.8%, p = <0.001) than low exercise attendees during lockdown.

Discussion

Home-based exercise, walking, and cycling were most frequently reported during lockdown. Participants reported a small decrease in exercise duration and frequency compared with pre-lockdown. Closure of fitness clubs impacted low attendees more than high attendees.

Psychometric testing of the Maltese versions of the Exercise Benefits/Barriers Scale and Exercise Motivation Inventory – 2

Background

Consideration of psychological factors towards exercise participation is important, especially when placed within a cultural context.

Objective

The aim of this study was to translate the Exercise Benefits/Barriers Scale and Exercise Motivation Inventory-2 to Maltese and undertake psychometric testing.

Methods

Maltese-speaking participants (n = 170) aged 18 to 69 years were recruited. 72% completed both questionnaires twice within an 8-to 48-hour period. Reliability was calculated using the Spearman correlation, intraclass correlation coefficient, and Bland–Altman plots. Convergent construct validity was tested using Spearman correlation between theoretical variables.

Results

In total 155 participants completed the questionnaires at both time points. The test/re-test reliability of the two questionnaires was >0.7 for all analyses. Correlations for validity were statistically significant (p < 0.05).

Conclusion

The translated tools have similar psychometric properties to the original version; the authors recommend that health care professionals and physical activity practitioners use these tools when examining population-level physical activity behaviour among Maltese-speaking individuals.

A New Health Promotion Program That Includes Wadaiko Rhythm Exercise to Maintain the Health of Persons Excluded from Receiving Specific Health Guidance

This study examined the effectiveness of a new health promotion program, which is a collective intervention program aimed at improving lifestyle habits. It was designed as a one-year prospective cohort study. This program targeted non-obese persons at risk of developing lifestyle-related diseases and participants with hypertension, dyslipidemia, or hyperglycemia who were not included in the specific health guidance system in Japan. The Wadaiko rhythm exercise, which is a traditional performing art, is incorporated into this intervention as an enjoyable routine that can help participants continue the program, preventing them from dropping out. After a one-year follow-up, the effectiveness of the health promotion program was evaluated in 18 participants (2 males, 16 females; mean age 65.2 ± 3.4 years) and 92 controls. The results showed that triglyceride in the intervention group significantly decreased (−24.5 mg/dL; p = 0.02; 95% confidence interval [CI], −44.73 to −4.27) and high-density lipoprotein cholesterol significantly increased (+6.1 mg/dL; p < 0.01; 95% CI, 2.46 to 9.65), although levels in the control group did not change. These results suggest that the health promotion program could contribute to lifestyle habit improvements in those who are excluded from receiving specific health guidance.

Weight Cycling and Dieting Behavior in Fitness Club Members

Background

Along with the rising prevalence of high body-mass index (BMI), there is also increased emphasis on leanness and fitness. Both these trends suggest that many individuals are concerned about weight management and may try to lose weight. Using data from the research project "Fitness clubs - a venue for public health?", we aimed to describe weight cycling and energy-restricted dieting in men and women at start-up of fitness club membership, and to investigate influencing factors [age, BMI, educational level, self-classified overweight/obesity, compliance with nutritional guidelines, unhealthy weight control strategies and self-perceived health (SPH)].

Methods

In a cross-sectional online survey, 250 men and women from 25 fitness clubs in Oslo, reported anthropometrics, self-classified weight group, weight cycling, weight loss/gain, eating habits/dieting, and background/health information. Enrollment was limited to adult (≥18 years) novice exercisers (exercising <60 min/week at a moderate or vigorous intensity or brisk walking <150 min/week, the past six months) with less than four weeks of membership. Factors associated with weight cycling were examined using simple and multiple logistic regression, separated for men and women.

Results

In both sexes (mean age: 36.4 ± 11.3, range 18-71 years), a high number reported substantial weight fluctuation (+/-5 kg) the past 12 months (men: 50% and women: 62%, mean difference 12%, 95% CI -0.3 to 23.8, p=0.056) and unhealthy weight control strategies (men: 24.8% and women: 47.2%, mean difference 22.4%, 95% CI 10.5 to 33.4, p<0.001). Weight cyclers had a higher mean BMI compared with non-cyclers (mean difference -1.5, 95% CI -2.6 to - 0.4, p= 0.003). Further, the difference in body weight was 6.7 kg (95% CI 2.2 to 10.8, p=0.004) and 10.8 kg (95% CI 5.8 to 15.8, <0.001) in men and women, respectively. Besides BMI status, self-classified overweight/obesity was the strongest predictor of reporting weight cycling (men: OR 5.54, 95% CI 2.03 to 15.12, p<0.01 and women: OR 7.17, 95% CI 2.48 to 20.68, p<0.001).

Conclusion

In novice exercisers, a large proportion reported weight cycling and unhealthy weight control strategies, and both were more prevalent in women than in men. Self-classified overweight was found to be the most important factor influencing weight cycling.

Motivation Levels and Goals for the Practice of Physical Exercise in Five Different Modalities: A Correspondence Analysis

The identification of the practitioner’s profile regarding their motivation level for physical exercise engagement could be a behavioral strategy to increase exercise adherence. The present study investigates the associations between motivation levels, modalities practiced, and goals concerning the practice of physical exercise among physical exercise practitioners. A total of 100 physical exercise practitioners, of which 67 were women, took part in this study. The participants were engaged in extreme fitness program, strength training, fight training, Pilates, and functional training. Motivation level (BREQ-3) and expectations regarding regular physical exercise (IMPRAF-54) were assessed. A multiple correspondence analysis demonstrates preferential relationships between descriptive and non-inferential variables. Strength training and fight training practitioners seek these modalities with the goals of “Health” and “Aesthetics,” demonstrating low autonomy in relation to the behavior for the practice of physical exercise. Extreme conditioning program and functional training practitioners have as goal “Pleasure,” demonstrating medium and high levels of autonomy for such practice and Pilates practitioners have the goal of “Stress Control.” To promote and encourage the regular practice of physical exercise, this strategy could be used to take actions that increase the public’s intention to start or continue in a physical exercise program.

The Influence of Acute Sprint Interval Training on Cognitive Performance of Healthy Younger Adults

There is considerable evidence showing that an acute bout of physical exercises can improve cognitive performance, but the optimal exercise characteristics (e.g., exercise type and exercise intensity) remain elusive. In this regard, there is a gap in the literature to which extent sprint interval training (SIT) can enhance cognitive performance. Thus, this study aimed to investigate the effect of a time-efficient SIT, termed as "shortened-sprint reduced-exertion high-intensity interval training" (SSREHIT), on cognitive performance. Nineteen healthy adults aged 20-28 years were enrolled and assessed for attentional performance (via the d2 test), working memory performance (via Digit Span Forward/Backward), and peripheral blood lactate concentration immediately before and 10 min after an SSREHIT and a cognitive engagement control condition (i.e., reading). We observed that SSREHIT can enhance specific aspects of attentional performance, as it improved the percent error rate (F%) in the d-2 test (t (18) = -2.249, p = 0.037, d = -0.516), which constitutes a qualitative measure of precision and thoroughness. However, SSREHIT did not change other measures of attentional or working memory performance. In addition, we observed that the exercise-induced increase in the peripheral blood lactate levels correlated with changes in attentional performance, i.e., the total number of responses (GZ) (rm = 0.70, p < 0.001), objective measures of concentration (SKL) (rm = 0.73, p < 0.001), and F% (rm = -0.54, p = 0.015). The present study provides initial evidence that a single bout of SSREHIT can improve specific aspects of attentional performance and conforming evidence for a positive link between cognitive improvements and changes in peripheral blood lactate levels.

The effect of initial support on fitness center use in new fitness center members. A randomized controlled trial

•

There is a lack of research on what fitness centers do to support new members.

•

The effect of initial support delivered via telephone and e-mail was investigated.

•

There was an effect on bookings with a fitness trainer first six months.

•

There was no effect on days with visits or membership duration during four years.

•

More visits the first six months were associated with longer membership duration.

This provider and participant blinded parallel-group randomized controlled trial aimed to investigate if initial support given to new members via telephone and e-mail, compared to self-directed use, had an effect on booking with a fitness trainer, number of visits to the center, and membership duration. Participants included 356 new members, 174 randomized to the intervention group, and 182 to the control group. The intervention group received support to use the fitness center facilities through two phone calls and one e-mail over the first eight weeks of their membership. The control group got usual practice, which is self-directed use.

Participants in the intervention group were more likely to book at least one session with a fitness trainer during the first six months (odds ratio 1.6, 95% confidence interval (CI) 1.0–2.5). However, the intervention did not influence the number of visits (mean difference after four years −11.7 days, 95% CI −34.8 to 11.3) or time to membership termination during the follow-up period (hazard ratio 1.1, 95% CI 0.8–1.3).

In conclusion, initial support to use the fitness center facilities given to new fitness center members via telephone and e-mail increased the proportion of bookings with a fitness trainer during the first months of the membership, but it did not have an effect on the number of visits or membership termination during four years.

Exercise behavior patterns and associations with subjective well-being during the COVID-19 pandemic: A cross-sectional study in Brazil

Introduction

The COVID-19 pandemic has affected the behavior and practice of planned and structured physical exercises. This study aimed to investigate the association between changes in physical exercise behavior and subjective well-being during the COVID-19 pandemic in Brazil.

Methods

This cross-sectional study was performed in Brazil and included a total of 595 individuals recruited through social media platforms, personal and professional contacts. Each participant responded to self-completed questionnaire via an online survey between March 29 and May 7, 2020. The characteristics of physical exercise (frequency, intensity, and duration) were collected before and during the pandemic. The subjective state of mood was measured through the Profile of Mood States (POMS) questionnaire during the pandemic. A generalized linear model was employed for the analysis.

Results

Exercising during the pandemic only promoted protective effects on the subjective mood. An exercise frequency of 3-5 days/week was associated with improved vigor and between 6-7 days/week with improved vigor and total mood when compared to not exercising at all (p < .005). A moderate intensity was associated with improved vigor, and a high intensity with improved vigor, total mood, and less fatigue in comparison to low-intensity exercise programs (p < 0.05). Maintaining the same duration of exercise sessions during the pandemic was associated with lower scores of depression/anxiety, fatigue and irritability, and improved vigor and total mood, while performing longer sessions with improved vigor when compared to short exercise sessions (p < .005).

Conclusion

Regular exercising during the pandemic promotes positive changes in the subjective well-being. Our results reinforce the need for adopting and maintaining a physical exercise routine during the COVID-19 pandemic as a protective effect on mental health.

Does Self-Perception Equal the Truth When Judging Own Body Weight and Height?

Background: Data from the research project “Fitness clubs—a venue for public health?” provided an opportunity to evaluate the accuracy of self-reported body weight and height, and subsequent Body Mass Index (BMI), as well as the “trueness” of novice exercisers perception of weight status category, which has not been examined in this population. The aims were to examine self-reported body weight, height, and calculated BMI data from an online survey compared with measured data at fitness club start-up, investigate how accurately novice exercisers place themselves within self-classified weight group (underweight, normal weight, overweight, and obese), and compare this with fitness club attendance at three months follow-up. Methods: Prior to anthropometric measurements, 62 men and 63 women responded to an online questionnaire, including body weight (kilogram, kg) and height (centimeters, cm), and self-classified weight group (“I think I am … underweight, normal weight, overweight, obese”). We used the following statistical analysis: Paired sample t-tests, a Bland–Altman plot kappa statistics, chi-squared tests, and a logistic regression. Results: Mean difference of BMI calculated from self-reported and measured data was 0.06 (95% CI −0.29 to 0.17, p = 0.593) in men, and 0.16 (95% CI −0.40 to 0.09, p = 0.224) in women, with four participants being outliers of the 95% limits of agreement (Bland-Altman plot). Allowing a difference of 0.5 kg between self-reported and measured weight, we found that 16% reported their weight correctly, 31.2% underreported (−1.89 ± 1.59 kg), and 52.8% overreported (1.85 ± 1.23 kg), with no sex differences (p = 0.870). Further, our results suggest that both sexes may have difficulty recognizing overweight/obesity in themselves, and particularly men are likely to underreport their perceived weight group compared with women. More than half (53.3%) of the overweight men perceived themselves to be normal weight (women: 14%), and only 33.3% of obese men and women correctly classified themselves as being obese. We did not find any difference between participants correctly or incorrectly classifying weight group and fitness club attendance (≥2 times a week) at three months follow-up. Conclusion: Both sexes reported body weight and height reasonably accurately, and BMI based on self-report appears to be valid measure. Still, a large proportion of novice exercisers do not recognise their own overweight or obesity status, which may in part explain why public health campaigns do not reach risk populations.

What Makes Individuals Stick to Their Exercise Regime? A One-Year Follow-Up Study Among Novice Exercisers in a Fitness Club Setting

Objectives

A fitness club may be an important arena to promote regular exercise. However, authors have reported low attendance rates (10 to 37%) the first months after individuals sign up for membership. It is therefore important to understand the reasons for poor exercise adherence. In this project, we aimed to investigate different psychosocial factors that might increase the likelihood of reporting regular exercise the first year of a fitness club membership, including self-efficacy, motives, social support, life satisfaction, and customer satisfaction.

Methods

New members (≤4 weeks membership, n = 250) classified as novice exercisers (exercise < 60 min/week the last 6 months) from 25 multipurpose gyms were followed for 1 year. Data were collected by an electronic survey including background and health factors, self-efficacy, social support, life satisfaction, motives, customer satisfaction, and exercise attendance, and was answered at start-up and after three (n = 224), six (n = 213), and 12 (n = 187) months. It is well established in the literature that ≥2 exercise sessions/week improve physical fitness in novice exercisers (if adhered to). Hence, we divided the participants into regular exercise attendance (≥2 sessions/week) and non-regular exercise attendance (≤1 session/week, exercise dropout, or membership dropout) in the analysis.

Results

A mixed-effects logistic regression model revealed that the strongest predictor for reporting regular exercise attendance was higher levels of the motive “enjoyment” (OR = 1.84, p ≤ 0.001, 95% CI for OR = 1.35, 2.50), followed by self-efficacy “sticking to it” (OR = 1.73, p = 0.002, 95% CI for OR = 1.22, 2.46) and social support from friends and family (OR = 1.16, p ≤ 0.001, 95% CI for OR = 1.09, 1.23).

Conclusion

In novice exercisers, regular exercise at three, six, and 12 months was associated with higher scores of the motive “enjoyment,” self-efficacy (“sticking to it”), and social support compared with non-regular exercise. Our results show that the majority of new fitness club members do not achieve regular exercise behavior.

The effects of exergames on muscle strength: A systematic review and meta-analysis

This systematic review and meta-analysis examined studies on the chronic effects of exergames on muscle strength in humans. PubMed, Scopus, CENTRAL, Web of Science, SciELO, Biblioteca Virtual em Saúde, and Google Scholar were searched, and manual searches of the reference lists of included studies and hand-searches on Physiotherapy Evidence Database and ResearchGate were conducted from inception to August 10, 2020. Randomized and non-randomized exergame intervention studies with or without a non-exercise group and/or a "usual care intervention group" (any other intervention that did not incorporate exergames), which evaluated muscle strength through direct measurements, were included. Forty-seven and 25 studies were included in the qualitative review and meta-analysis, respectively. The between-groups meta-analyses showed no significant differences between exergames and non-exercise control groups for handgrip strength in heathy/unhealthy middle-aged/older adults or knee extension maximum voluntary isometric contraction (MVIC) in healthy older adults. However, exergames provided a greater increase in handgrip strength, knee flexion MVIC, and elbow extension MVIC, but not knee extension MVIC or elbow flexion MVIC, in individuals with different health statuses when compared to usual care interventions. Also, there was a greater increase in handgrip strength in children with hemiplegic cerebral palsy favouring usual care plus exergames compared to usual care interventions. These results suggest that exergames may improve upper and lower limb muscle strength in individuals with different heath statuses compared to usual care interventions, but not muscle strength in middle age/older adults after accounting for random error. Also, exergames appear to be a useful tool for improving handgrip strength in children with hemiplegic cerebral palsy when added to usual care. However, as the exergame interventions were applied in different populations and there currently are many different approaches to perform exergames, future randomized controlled trials with high methodological quality and large sample sizes are needed to provide more compelling evidence in favour of a specific exergame protocol, or to elucidate exergame protocol design principles that appear to strongly influence outcomes.

Stay True to Your Workout: Does Repeated Physical Testing Boost Exercise Attendance? A One-Year Follow-Up Study

No prospective studies have investigated if repeated testing of physical performance and body composition are associated with exercise attendance or patterns in fitness club members. This study aimed to investigate if repeated physical testing was associated with exercise attendance and patterns in gym members and to report prospective data on use of the fitness club`s facilities and products. Untrained new members were recruited and divided into a test group (n = 125) and as controls (n = 125). All participants answered a survey including exercise involvement, at onset, and after 3, 6, and 12 months follow-up. The test group also measured body composition, maximal oxygen uptake, and maximal muscle strength (onset, and after 3 and 12 months). In total 73.6% answered all surveys, and in the test group, 44.8% completed all physical tests. Regular exercise attendance was defined as ≥2 sessions/week. Repeated testing showed no association with long-term regular exercise attendance (test group: 19.6%, controls: 19.8%; p = 0.638). At 3 months, a lower proportion in the test group reported engagement in resistance exercise (35.3% and 60.2%; p = 0.003) and had lower exercise frequency (2.0 and 2.6 days/week; p = 0.008) than controls. The test group had higher participation in group exercise classes (28.0% and 13.6%; p = 0.040). Exercise frequency decreased from onset to 12 months (from 2.6 to 2.2 days/week; p = 0.025) At 3, 6, and 12 months, 51.8%, 37.6%, and 37.4% reported regular exercise attendance, and 16.9% at all follow-ups. At all time-points, most common workout mode was individual resistance exercise (43.8% to 46.3%). Few attended group exercise classes (7.5% to 13.8%) or used a personal trainer (22.5% to 27.5%). Repeated physical testing did not improve exercise attendance, and we found no changes in members` use of the fitness club`s facilities and products. Only 16.9% reported regular exercise attendance throughout the first year of membership.

Motives and barriers to initiation and sustained exercise adherence in a fitness club setting-A one-year follow-up study

No prospective studies have investigated motives and barriers to exercise in new untrained fitness club members. The aims of the present prospective longitudinal study were to (a) examine proportions reporting regular exercise, non‐regular exercise, and exercise dropout; (b) identify motives and barriers to exercise; and (c) compare motives between regular and non‐regular exercisers the first year of fitness club membership. New members (n = 250) were followed for 1 year. A questionnaire including demographics, exercise frequency, motives (EMI‐2), and barriers (18 common reported barriers) was used, and 184 answered at four time points (onset, and after 3, 6, and 12 months). Participants were categorized into regular exercise: ≥2 sessions/wk or non‐regular exercise: ≤1 session/wk, exercise relapse, or dropout. At 3, 6, and 12 months, 63.4%, 59.6%, and 57.2% exercised regularly, whereas 20.1%, 21.1%, and 28.3%, dropped out, respectively. Throughout the follow‐up, 37% reported regular exercise. At all time points, motives regarding positive health and strength/endurance were rated highest on a six‐point scale. Exercise dropouts rated priority as the greatest barrier. Regular exercisers rated the motives enjoyment (such as “I enjoy the feeling of exerting myself”) and challenge (such as “To give me goals to work towards”) higher than non‐regular exercisers (P = ≤.05). In conclusion, less than half exercised regularly, and most members were motivated by factors such as positive health and physical fitness the first year of fitness club membership. Higher levels of the motives enjoyment and challenge were associated with regular exercise.
