Promoting Physical Activity and Exercise

Enhanced body shape change coupled with PA is the key to hypertension management for urban residents

The present study aimed to assess the relationship between body shape, physical activity (PA), and systolic blood pressure (SBP) and diastolic blood pressure (DBP). A novel visualization method was used to examine the effects of body shape combined with physical activity on hypertension. Data from 54,303 participants were obtained from the China Health and Nutrition Survey (CHNS) and analyzed using logistic regression models and standardized regression coefficients of linear models. These models were used to explore factors and effects of body shape indices and other parameters on SBP and DBP. The logistic regression model revealed that compared to transport-related PA, the aggregated variables (weight and waist) were associated with a 2.44-fold and 1.65-fold increase in the risk of hypertension, respectively (p < .05). The average aggregated standardized coefficient of the linear model, based on 1000 bootstrap resamples, indicated that the Base Shape group had the strongest explanatory power for hypertension, followed by the Habits group. However, the explanatory power of the PA group was around 10 and 22 times lower than that of the Base Shape group for DBP and SBP, respectively (p < .05). These results demonstrate that increasing physical activity, with emphasizing a healthy body shape, and adopting positive lifestyle habits can effectively contribute to the prevention and control of hypertension.

Leisure Sedentary Behavior, Physical Activities, and Cardiovascular Disease Among Individuals With Metabolic Dysfunction-Associated Fatty Liver Disease

BACKGROUND

Metabolic dysfunction-associated fatty liver disease is a significant risk factor for cardiovascular disease (CVD). This study assesses the association between leisure-time physical activity, sedentary behavior, and CVD risk among patients with metabolic dysfunction-associated fatty liver disease, considering genetic predisposition to CVD.

METHODS

This cohort study included 157 794 participants with metabolic dysfunction-associated fatty liver disease from the UK Biobank who were free of CVD at baseline. The study measured leisure-time sedentary behaviors (watching TV, using a computer, and driving) and physical activities (walking for pleasure, light and heavy do-it-yourself activities, strenuous sports, and other exercises) in terms of frequency and duration over the 4 weeks before assessment. Both a Cox proportional hazard model and an isotemporal substitution model were utilized in the study to assess the association between leisure sedentary behavior, physical activities, and CVD risk.

RESULTS

During a median 12.5 years of follow-up, 26 355 CVD cases were reported, including 19 746 coronary heart disease, 4836 stroke, and 7398 heart failure cases. High physical activity levels were linked to a significantly lower risk of CVD (21%), coronary heart disease (20%), stroke (15%), and heart failure (31%). In contrast, individuals with >6.5 h/d of sedentary behavior faced a 16% to 21% higher risk of these conditions compared with those with ≤3.5 h/d. Notably, replacing 30 minutes of inactivity with physical activity reduced CVD risks by 3% to 16%, particularly with strenuous sports. A significant interaction was observed between physical activity, sedentary behavior, and genetic predisposition in relation to stroke risk.

CONCLUSIONS

Among patients with metabolic dysfunction-associated fatty liver disease, higher leisure-time physical activity levels correlate with reduced CVD risks, while increased sedentary behavior is linked to higher CVD risks. Replacing sedentary time with physical activity consistently shows benefits in reducing CVD outcomes, irrespective of genetic predisposition.

A systematic review and meta-analysis of Nordic walking for chronic heart failure with low left ventricular ejection fraction

BACKGROUND

Nordic walking (NW) has been reported to be beneficial in various chronic diseases.

OBJECTIVE

To determine whether NW improves function in patients with heart failure (HF) with low left ventricular ejection fraction more than conventional cardiac rehabilitation or usual care.

METHODS

Systematic literature searches in PubMed, ScienceDirect, and Web of Science were conducted. According to patient, intervention, comparison, and outcome (PICO) principles, a stepwise selection process was completed to identify eligible studies. Only randomized controlled trials (RCTs) were included in this systematic review and meta-analysis. Pooled effects were determined using a random effect analysis model for the meta-analysis.

RESULTS

A total of 282 participants from four RCTs were included. The improvement of peak oxygen consumption (peak VO2) was greater in the NW group than in the control group (mean difference [MD] = 2.18 mL/kg/min; 95% confidence interval [CI] = 1.35-3.01; p < .01). The improvement of the 6-minute walk test (6MWT) distance was also greater in the NW group than in the control group (MD = 16.51 meters; 95% CI = 3.23-29.80; p = .01).

CONCLUSION

This systematic review highlights the benefits of NW training in patients with chronic HF, particularly those with systolic dysfunction. Specifically, NW walking was associated with increased peak VO2 and 6MWT improvement compared to conventional cardiac rehabilitation or usual care. These results suggest that NW may be a useful component of cardiac rehabilitation. However, additional larger studies with a wider range of patients are needed.

Empirical analysis of health-related behaviors among older Hakka adults: a latent class analysis

Background

Little is known about health-related behaviors of the older Hakka population in China. We aimed to explore the characteristics and correlates of health-related behaviors among older Hakka adults.

Methods

We used data from the China's Health-Related Quality of Life Survey for Older Adults 2018. Latent class analysis (LCA) defined latent classes of health-related behaviors for 1,262 older Hakka adults aged 60 and above. Generalized linear regression and multinomial logistic regression analysis were used to identify factors influencing the number and the latent classes of health-related behaviors, respectively.

Results

The LCA showed that the latent classes could be stratified as the risk group (14.82%), healthy group (55.71%), and inactive group (29.48%). Sex, age, years of education, current residence, living arrangement, average annual household income, and currently employed were associated with the number of healthy behaviors. Compared with the participants in the healthy group, widowed/others (OR = 5.85, 95% CI = 3.27, 10.48), had 15,001-30,000 (OR = 2.05, 95% CI = 1.21, 3.47) and 60,001 or higher (OR = 3.78, 95% CI = 1.26, 11.36) average annual household income, and currently employed (OR = 3.40, 95% CI = 1.99, 5.81) were highly associated with risk group. Additionally, the participants who are widowed/others (OR = 4.30, 95% CI = 2.70, 6.85) and currently employed (OR = 1.95, 95% CI = 1.27, 2.98) were highly associated with the inactive group.

Conclusion

This study identified factors specifically associated with older Hakka adults' health-related behaviors from an LCA perspective. The findings indicate that policymakers should give more attention to older adults living alone and implement practical interventions to promote health-related behaviors among them.

Diet Based on Pereskia aculeata Miller Flour Increases Muscle Volume and Modulates the Expression of Myokines in Mice Subjected to Resistance Training

The study aimed to evaluate the effects of Pereskia aculeata Miller (ora-pro-nobis [OPN]) flour on body and biochemical parameters, thermogenic activity, and molecular expression of markers in the muscle tissue of mice subjected to resistance training (RT). Twelve mice were randomly assigned to two groups (n=6 animals/group): G1: control (Control) fed a standard diet + RT and G2: experimental (OPN) fed a diet based on OPN flour + RT. The RT consisted of a 6-week program using a vertical ladder combined with a fixed weight attached to the animal. Several parameters were measured, including assessment of body composition, biochemical markers, thermogenic activity, and molecular (mRNA expression of interleukin (IL)-6, fibronectin type III domain-containing protein 5 (FNDC5), peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), nuclear respiratory factor 1 (NRF1), and mitochondrial transcription factor A (TFAM). The OPN group exhibited a decrease in body weight and visceral adiposity, higher energy expenditure, and lipid oxidation rate. In addition, it was observed an increase in muscle volume and in mRNA expression levels of IL-6, FNDC5, PGC-1α, and TFAM. These findings suggest that OPN flour could be a nutritional option to enhance performance in RT.

Health, Performance Ratings and Approachability of 50-60-Year-Old Sedentary Adults (ActIv-Study): Key Insights for Health Economy and Exercise Promotion

Despite significant prevention efforts, the numbers of physically inactive individuals, chronic illnesses, exhaustion syndromes and sick leaves are increasing. A still unresolved problem with exercise promotion is the low participation of sedentary persons. This collective term covers heterogeneous subgroups. Their engagement with movement campaigns and resistance to change are influenced by numerous factors. Our aim was to analyse survey data on health, performance, lifestyle habits and the approachability to physical activity campaigns obtained from the Germany-wide ActIv survey. From 2888 study participants aged 50-60 years, 668 persons were categorised into the subgroups "never-athletes", "sports-dropouts", "always-athletes" and "sports-beginners". Large and significant group differences were found for BMI, assessment of quality of life, health and fitness, risk factors and health problems. In total, 42.5% of "never-athletes" and 32.5% of "sports-dropouts" did not state any barriers to sport. There are substantial disparities between the non-athlete groups in terms of their motivation to exercise. In contrast, there are comparatively minor differences in motivation between "sports-dropouts" and "sports-beginners", whose health and fitness are the primary motivators for sport. Our analyses suggest that (i) negative health and performance trends cannot be compensated for by appeals for voluntary participation in exercise programmes and (ii) powerful incentive systems are required.

Reliability and Validity of the Global Physical Activity Questionnaire for Portuguese Adults

The Global Physical Activity Questionnaire (GPAQ) has been used often to assess physical activity (PA) patterns. However, the European Portuguese version of this instrument has not been validated. We aimed to validate the self-administered GPAQ, version 2, (GPAQv2) for Portuguese adults. We included 32 participants in a pilot study of a Portuguese adaptation of the test and 108 participants in an assessment of their PA patterns and sedentary behavior (SB) through the GPAQv2. For its validation, we compared the GPAQv2 to the International PA Questionnaire-Long Form (IPAQ-LF) (concurrent validity) and the ActiGraph wGT3X-BT accelerometer (criterion validity). We evaluated PA and SB at baseline and after seven consecutive days. Test-retest reliability with the Kappa test (k) and the Intraclass Correlation Coefficient (ICC) ranged from strong to almost perfect (k: 0.864-0.976) and from moderate to excellent (ICC: 0.56-0.994), respectively. Concurrent validity, assessed by Spearman's Correlation Coefficient, was moderate to substantial (rho: 0.471-0.680), and there was fair to substantial criterion validity (rho: 0.226-0.672). Bland-Altman plots showed that the GPAQv2 overestimated vigorous and moderate to vigorous PA and underestimated moderate PA. The largest difference values were related to SB, since the GPAQv2 underestimated sitting time. In sum, we found the GPAQv2 to have acceptable validity and reliability for assessing PA and SB patterns, and we recommend its use for Portuguese adults.

Health-Status Outcomes in Older Patients With Myocardial Infarction: Physiology-Guided Complete Revascularization Versus Culprit-Only Strategy

BACKGROUND

The FIRE trial (Functional Assessment in Elderly Myocardial Infarction Patients With Multivessel Disease) enrolled 1445 older (aged ≥75 years) patients with myocardial infarction and multivessel disease in Italy, Spain, and Poland. Patients were randomized to physiology-guided complete revascularization or treatment of the only culprit lesion. Physiology-guided complete revascularization significantly reduced ischemic adverse events at 1 year. This prespecified analysis investigated the changes between the 2 study groups in angina status, quality of life, physical performance, and frailty.

METHODS

Patients underwent validated scales at hospital discharge (baseline) and 1 year later. Angina status was evaluated using the Seattle Angina Questionnaire, health-related quality of life by EQ visual analog scale, physical performance by short physical performance battery, and frailty by the clinical frailty scale. Mixed models for repeated measures analysis were used to study the association between the treatment arms, time, and scales.

RESULTS

Baseline and 1-year Seattle Angina Questionnaire, EQ visual analog scale, short physical performance battery, and clinical frailty scale were collected in around two-thirds of the entire FIRE study population. The mean age was 80.9±4.6 years (female sex, 35.9%). Overall, 35.3% were admitted for ST-segment-elevation myocardial infarction, whereas the others were admitted for non-ST-segment-elevation myocardial infarction. Physiology-guided complete revascularization, compared with culprit-only revascularization, was associated with greater improvement in terms of angina status (Seattle Angina Questionnaire summary score, 7.3 [95% CI, 6.1-8.6] points), health-related quality of life (EQ visual analog scale, 6.2 [95% CI, 4.4-8.1] points), and physical performance (short physical performance battery, 1.1 [95% CI, 0.9-1.3] points). After 1 year, patients randomized to culprit-only revascularization experienced a deterioration in frailty status (clinical frailty scale, 0.2 [95% CI, 0.1-0.3] points), which was not observed in patients randomized to physiology-guided complete revascularization.

CONCLUSIONS

The present analysis suggested that a physiology-guided complete revascularization is associated with consistent benefits in terms of angina status, quality of life, physical performance, and the absence of further deterioration of the frailty status.

Initiating and Maintaining a Lifestyle Program Directed at Persons Living with Severe Mental Illness in a Municipality Care Setting

Lifestyle programs are effective in improving the health of persons living with severe mental illness. However, the implementation of these programs and making them a sustainable part of daily care remain challenging. This qualitative descriptive study aimed to describe how staff worked with and experienced a lifestyle program in a municipality mental health care setting over time. The program intended to support persons living with severe mental illness to overcome health challenges. Data was collected at three time points spanning 7 years. The staff motivated the participants with SMI with severe mental illness to take part in the program, prepared them, and gave them individualized lifestyle support. A key factor of the program's implementation was the staff's interest and engagement in lifestyle questions. According to the staff it was apparent that small efforts such as running the present program could give synergic health effects such as improved mental- and social health. This study shows that it is feasible to conduct this lifestyle program in ordinary care without considerable resources. However, support from management is crucial, as well as the development of guidelines and routines of the work with lifestyle questions.

Relationships among age, motivation, and exercise among women Veterans

Physical activity (PA) and exercise are central to maintaining health, however research has shown steep declines in PA and exercise among women Veterans as they age. Though motivation may be an important contributor to initiating and sustaining exercise that may change across the lifespan, little is known about exercise motivation and its relation to age and exercise behavior among women Veterans. This cross-sectional study sought to describe exercise motivations, examine relationships among exercise motivations and age, and explore the degree to which age and motivation predict self-reported exercise behavior among women Veterans. We conducted a secondary data analysis from a regional mail survey of 197 women Veterans (mean age = 51; SD = 10.5) enrolled in Veterans Health Administration primary care in a northeastern region (N = 180 in analysis). Measures included demographics (age, body mass index), self-reported exercise motivation, and an estimate of average weekly exercise. Participants endorsed multiple motivators for exercise, most prominently fitness and health management. Age was significantly negatively related to amount of exercise and with socializing as an exercise motivation. After accounting for body mass index, age was a significant predictor of exercise behavior, and exercise motivations accounted for an additional 7.3% of variance in self-reported weekly exercise. Our results suggest that although motivation is a potentially important predictor of exercise, factors beyond motivation may better predict exercise in women Veterans. Further research is needed on personal and practical facilitators and barriers to exercise in this population.

Telic-Paratelic Dominance and Heart Rate Variability in Athletes Engaged in Power and Endurance Training

Purpose: The current study aimed to evaluate the telic-paratelic tendency and heart rate variability in athlete participants from different sports activities.Methods: We assigned 117 healthy participants (M age = 20, SD = 3 years) into three groups according to their training activity: power-trained (PT; n=43), endurance-trained (ET; n=36), and healthy untrained individuals (n=38). We assessed their telic-paratelic tendencies with the validated Telic Dominance Scale and their autonomic nervous system activity with heart rate variability (HRV) analyses.Results: Our findings revealed no significant differences in the telic-paratelic tendencies between ET and PT groups. However, significant differences were observed between athletes and untrained individuals (p = 0.001). Indeed, compared to untrained participants, ET and PT athletes had a greater telic tendency (both p = 0.001), were more focused on planning orientation (ET: p = 0.003; PT: p=0.001), and less often avoided arousal or activation (For ET 31% and for PT 26% of participants). The paratelic tendency was more important in untrained individuals, with most of these participants lacking in seriousmindedness and planning. In addition, we found higher HRV in paratelic ET athletes (SDNN p = 0.050, LF p = 0.022, and LF/HF p = 0.031) compared to their telic peers.Conclusion: our results suggest that sport activity did not influence the telic-paratelic tendency. Nevertheless, this tendency differentiates trained from untrained participants. HRV was higher among paratelic ET athletes, potentially reflecting less stress and more training adaptability in these athletes.

Ethnic Disparities in the Risk Factors, Morbidity, and Mortality of Cardiovascular Disease in People With Diabetes

Cardiovascular disease (CVD) is the leading cause of death in people with diabetes. Compared with European Americans, African Americans have more favorable lipid profiles, as indicated by higher high-density lipoprotein cholesterol, lower triglycerides, and less dense low-density lipoprotein particles. The less atherogenic lipid profile translates to lower incidence and prevalence of CVD in African Americans with diabetes, despite higher rates of hypertension and obesity. However, African Americans with CVD experience worse clinical outcomes, including higher mortality, compared with European Americans. This mini-review summarizes the epidemiology, pathophysiology, mechanisms, and management of CVD in people with diabetes, focusing on possible factors underlying the "African American CVD paradox" (lower CVD incidence/prevalence but worse outcomes). Although the reasons for the disparities in CVD outcomes remain to be fully elucidated, we present a critical appraisal of the roles of suboptimal control of risk factors, inequities in care delivery, several biological factors, and psychosocial stress. We identify gaps in current knowledge and propose areas for future investigation.

Exploring physical activity preferences and motivation in long-term cardiac prevention: An Austrian cross-sectional survey

Cardiac rehabilitation (CR) patients often do not sustain physical activity (PA) behaviour in the long run, once they progress into a self-management stage of secondary prevention. This study aimed to explore former CR patients' PA preferences, determinants (i.e., influencing factors) and motivation for sustained PA engagement. We conducted a cross-sectional multi-centre survey using an original questionnaire based on prior qualitative interviews with cardiac patients. Five CR centres in Austria posted 500 questionnaires to former CR patients who had completed CR approximately three years prior, and 117 patients (23%) responded. Descriptive analysis was used to analyse closed-ended questions, and self-determination theory (SDT) was applied as a qualitative framework to analyse open-ended questions concerning motivation for PA engagement. Patients were generally physically active, but the majority (75.3%) did not fulfil the World Health Organisation's recommendations for aerobic PA and muscle strengthening. Most patients preferred being physically active outdoors (70%), engaging in aerobic-related (95%), individual and non-competitive exercises, with cycling (52%), walking (32%) and hiking (25%) among the most popular activities. Main determinants of PA were health, pain and motivation for 80%, 68%, 67% of patients, respectively. A subset of patients (77%) expanded on their motivations behind PA. According to SDT, most reasons (90%) were regulated by autonomous motivation (either extrinsically autonomously-regulated or intrinsic motivation) and stemmed mostly from health-related goals (e.g., fitness, general health, weight control), future quality-of-life aspirations (e.g., self-sufficiency in old age, presence for loved ones, preserving mobility) and enjoyment of PA. Patients' responses underscore the importance of promoting not only general PA, but also muscle strengthening training in CR interventions to maximise optimal health benefits. Our data further suggest that interventions which are aligned to patients' health goals and foster autonomous motivation may be particularly beneficial in increasing adherence to PA in the long-term.

Weight loss and lifestyle intervention for cardiorespiratory fitness in obstructive sleep apnea: The INTERAPNEA trial

INTRODUCTION

Although recent trials have shown benefits of weight loss and lifestyle interventions on obstructive sleep apnea (OSA) severity and comorbidities, the effect of these interventions on cardiorespiratory fitness (CRF) remains unknown. This study aimed to investigate the effects of an interdisciplinary weight loss and lifestyle intervention on CRF and self-reported physical fitness in adults with OSA.

METHODS

Eighty-nine men aged 18-65 years with moderate-to-severe OSA and a body mass index ≥25 kg/m2 were randomly assigned to a usual-care group or an 8-week interdisciplinary weight loss and lifestyle intervention. CRF was assessed through the 2-km walking test, and the International Fitness Scale (IFIS) was used to assess self-reported physical fitness.

RESULTS

As compared with usual-care, the intervention group had greater improvements at intervention endpoint in objective CRF (6% reduction in 2-km walking test total time, mean between-group difference, -1.7 min; 95% confidence interval, -2.3 to -1.1), and self-reported overall physical fitness (18% increase in IFIS total score, mean between-group difference, 2.3; 95% CI 1.2 to 3.3). At 6 months after intervention, the intervention group also had greater improvements in both 2-km walking test total time (10% reduction) and IFIS total score (22% increase), with mean between-group differences of -2.5 (CI 95%, -3.1 to -1.8) and 3.0 (CI 95%, 1.8 to 4.1), respectively.

CONCLUSIONS

An 8-week interdisciplinary weight loss and lifestyle intervention resulted in significant and sustainable improvements in CRF and self-reported physical fitness in men with overweight/obesity and moderate-to-severe OSA.

Development and feasibility assessment of a virtual reality-based aerobic exercise program with real-time pulse rate monitoring on hemodynamic and arterial stiffness in healthy people: a pilot study

Introduction

Virtual reality (VR) exercises are reportedly beneficial as a physical activity tool for health promotion and rehabilitation, and can also help individuals exercise under professional supervision. We developed and investigated the potential feasibility of a VR-based aerobic exercise program using the XBOX ONE console and Kinect sensor with real-time pulse rate monitoring. The VR setting consisted of two-dimensional (2D) environments via computer, laptop, or television screens. In addition, the study investigated the potential feasibility of the VR-based exercise program on hemodynamic response and arterial stiffness in healthy participants of various ages.

Methods

Healthy participants (n = 30) aged > 18 years were enrolled in the VR exercise-based program. All participants were required to wear a polar heart rate (HR) monitor set for moderate-intensity exercise, targeting 40%-59% of their HR reserve. Hemodynamic and arterial stiffness (pulse wave velocity) were noninvasively measured. The Borg scale rate of perceived exertion (RPE) was also assessed.

Results

Following a VR-guided exercise routine, all participants performed moderate-intensity exercise with no adverse health outcomes during or after the exercise. The effects of VR-based aerobic exercise extended beyond enhanced central hemodynamic and arterial stiffness. However, neither hemodynamic nor arterial stiffness showed significant differences before and after the VR exercise, except for a higher RPE response following the exercise program.

Conclusion

VR-based aerobic exercise with pulse rate monitoring is a promising physical activity tool to induce physiological changes and impact dyspnea scales and is also feasible for administration to healthy populations.

Exploring Possible Links: Thigh Muscle Mass, Apolipoproteins, and Glucose Metabolism in Peripheral Artery Disease-Insights from a Pilot Sub-Study following Endovascular Treatment

Peripheral artery disease (PAD) compromises walking and physical activity, which results in further loss of skeletal muscle. The cross-sectional area of the thigh muscle has been shown to be correlated with systemic skeletal muscle volume. In our previous pilot study, we observed an increase in thigh muscle mass following endovascular treatment (EVT) in patients with proximal vascular lesions affecting the aortoiliac and femoropopliteal arteries. Considering the potential interactions between skeletal muscle, lipid profile, and glucose metabolism, we aimed to investigate the relationship between thigh muscle mass and apolipoproteins as well as glucose metabolism in PAD patients undergoing EVT. This study is a prespecified sub-study conducted as part of a pilot study. We prospectively enrolled 22 symptomatic patients with peripheral artery disease (PAD) and above-the-knee lesions, specifically involving the blood vessels supplying the thigh muscle. The mid-thigh muscle area was measured with computed tomography before and 6 months after undergoing EVT. Concurrently, we measured levels of apolipoproteins A1 (Apo A1) and B (Apo B), fasting blood glucose, 2 h post-load blood glucose (using a 75 g oral glucose tolerance test), and glycated hemoglobin A1c (HbA1c). Changes in thigh muscle area (delta muscle area: 2.5 ± 8.1 cm2) did not show significant correlations with changes in Apo A1, Apo B, fasting glucose, 2 h post-oral glucose tolerance test blood glucose, HbA1c, or Rutherford classification. However, among patients who experienced an increase in thigh muscle area following EVT (delta muscle area: 8.41 ± 5.93 cm2), there was a significant increase in Apo A1 (pre: 121.8 ± 15.1 mg/dL, 6 months: 136.5 ± 19.5 mg/dL, p < 0.001), while Apo B remained unchanged (pre: 76.4 ± 19.2 mg/dL, 6 months: 80.5 ± 4.9 mg/dL). Additionally, post-oral glucose tolerance test 2 h blood glucose levels showed a decrease (pre: 189.7 ± 67.5 mg/dL, 6 months: 170.6 ± 69.7 mg/dL, p = 0.075). Patients who exhibited an increase in thigh muscle area demonstrated more favorable metabolic changes compared to those with a decrease in thigh muscle area (delta muscle area: -4.67 ± 2.41 cm2). This pilot sub-study provides insights into the effects of EVT on thigh muscle, apolipoproteins, and glucose metabolism in patients with PAD and above-the-knee lesions. Further studies are warranted to validate these findings and establish their clinical significance. The trial was registered on the University Hospital Medical Information Network Clinical Trials Registry (UMIN000047534).

China Trends in Physical Inactivity from 2013 to 2019: An Analysis of 4.23 Million Participants

INTRODUCTION

This study aimed to evaluate recent trends in physical inactivity prevalence by sociodemographic characteristics and the province of China's residence between 2013 and 2019.

METHODS

The study included 4,229,616 participants 40 yr or older from 414 geographically defined localities in China during the 7-yr period. Self-reported total physical inactivity was collected to determine the standardized prevalence of physical inactivity. Logistic regression analysis was used to examine the association between physical inactivity and stroke risk, obtaining odds ratios (OR) and 95% confidence intervals (CI).

RESULTS

Results showed that the standardized prevalence of physical inactivity increased from 22.12% (95% CI = 21.99%-22.45%) in 2013 to 28.79% (95% CI = 28.48%-29.19%) in 2019, with an absolute difference of 6.67% (95% CI = 6.15% to 7.16%) and a yearly increase rate of 5.03% (95% CI = 4.85% to 5.21%). In 2019, physical inactivity was higher in female and rural participants (female = 29.55%, rural = 29.46%) than in male and urban participants (male = 28.03%, urban = 28.26%). The prevalence of physical inactivity also varied by race/ethnic groups, with the highest prevalence observed among Uyghur (47.21%) and the lowest among Yizu (14.84%). Additionally, the prevalence of physical inactivity differed by province, ranging from 14.44% in Beijing to 50.09% in Tianjin in 2019. Multivariate analyses showed that physical inactivity was associated with a higher risk of stroke (OR = 1.17, 95% CI = 1.12-1.21, P < 0.001).

CONCLUSIONS

In conclusion, our study found an overall increase in physical inactivity prevalence among Chinese adults ≥40 yr old from 2013 to 2019, with significant variation across regions, sex, ages, and race/ethnic groups.

Spatiotemporal trends of cardiovascular disease burden attributable to low physical activity during 1990-2019: an analysis of the Global Burden of Disease Study 2019

OBJECTIVES

The epidemiological trends of cardiovascular disease (CVD) burden attributed to low physical activity (LPA) across various regions and countries are poorly understood. Hence, we assessed the global, regional, and national spatiotemporal trends of LPA-related CVD from 1990 to 2019.

STUDY DESIGN

We conducted a secondary analysis of the Global Burden of Disease Study 2019. The data on LPA-related CVD were examined with regard to sex, age, year, and Socio-Demographic Index (SDI).

METHODS

We assessed the temporal changes in age-standardized mortality rate (ASMR) and age-standardized death rate (ASDR) using the estimated annual percentage change (EAPC) over a 30-year period.

RESULTS

There were a staggering 0.64 million deaths and 9.99 million disability-adjusted life-years globally attributed to LPA-related CVD in 2019. The majority of the LPA-related CVD burden was observed in the population aged ≥80 years. It also indicated a high disease burden of LPA-related CVD in Central Asia, Arabian Peninsula, and North Africa. Although there has been a decline in ASMR and ASDR associated with LPA-related CVD on a global scale, the countries experiencing the most substantial increase in LPA-related CVD burden are Uzbekistan, Tajikistan, and Azerbaijan. The ASMR and ASDR remained stable in regions with low, low-middle, and middle SDI levels. The EAPCs of ASMR and ASDR were negatively linked with SDI in 2019.

CONCLUSIONS

From 1990 to 2019, LPA led to a significant and escalating burden of CVD in certain regions, namely, Uzbekistan, Tajikistan, and Azerbaijan. It is imperative for governments and policymakers to implement regulatory measures and strategic interventions aimed at mitigating this burden.

Use of Community Engagement Studios to Adapt a Hybrid Effectiveness-Implementation Study of Social Incentives and Physical Activity for the STEP Together Study

Physical activity is known to contribute to good health, but most adults in the United States do not meet recommended physical activity guidelines. Social incentive interventions that leverage insights from behavioral economics have increased physical activity in short-term trials, but there is limited evidence of their effectiveness in community settings or their long-term effectiveness. The STEP Together study is a Hybrid Type 1 effectiveness-implementation study to address these evidence and implementation gaps. This paper describes the process of adapting study procedures prior to the effectiveness trial using Community Engagement (CE) Studios, facilitated meetings during which community members provide feedback on research projects. Six CE Studios were held with community members from the priority population. They were conducted remotely because of the COVID-19 pandemic. Fifteen liaisons representing 13 community organizations and 21 community members from different neighborhoods in Philadelphia participated. Three elements of the study design were modified based on feedback from the CE Studios: lowering the age requirement for an 'older adult', clarifying the definition of family members to include second-degree relatives, and adding a 6-month survey. These adaptations will improve the fit of the effectiveness trial to the local context and improve participant engagement and retention. CE Studios can be used to adapt intervention strategies and other aspects of study design during hybrid implementation-effectiveness trials. This approach was successfully used with remote online participation due to the COVID-19 pandemic and serves as a model for future community-engaged implementation research.

Lifestyle Medicine: An Antidote to Cardiovascular Diseases

Despite numerous advances in basic understanding of cardiovascular disease pathophysiology, pharmacology, therapeutic procedures, and systems improvement, there hasn't been much decline in heart disease related mortality in the US since 2010. Hypertension and diet induced risk continue to be the leading causes of cardiovascular morbidity. Even with the excessive mortality associated with the COVID-19 pandemic, in 2020, heart disease remained the leading cause of death. Given the degree of disease burden, morbidity, and mortality, there is an urgent need to redirect medical professionals' focus towards prevention through simple and cost effective lifestyle strategies. However, current practice paradigm and financial compensation systems are mainly centered disease management and not health promotion. For example, the financial value placed on 3-10 min smoking cessation counseling (.24RVUs) is 47-fold lower than an elective PCI (11.21 RVUs). The medical community seems to be enamored with the latest and greatest technology, new devices, and surgical procedures. What if the greatest technology of all was simply the way we live every day? Perhaps when this notion is known by enough, we will switch to this lifestyle medicine technology to prevent disease in the first place.

Effects of 6-month customized home-based exercise on motor development, bone strength, and parental stress in children with simple congenital heart disease: a single-blinded randomized clinical trial

BACKGROUND

New "noncardiac" problems in children with congenital heart disease (CHD), such as developmental delay or long-term neurodevelopmental impairments, have attracted considerable attention in recent years. It is hypothesized that exercise might attenuate CHD-associated neurodevelopmental impairments; however, this has not been thoroughly investigated. The objective of this prospective, single-blinded, randomized controlled experiment was to evaluate the impact of customized home-based exercise for children with CHD.

METHODS

Children aged 0-5 years with echocardiography-confirmed simple CHD subtypes who were scheduled to undergo cardiac catheterization were screened for enrolment. Among 420 screened CHD children, 192 were enrolled and randomly assigned at a 1:1 ratio to receive a 6-month intervention (30 min daily customized home-based exercise program with supervision for no less than 5 days per week, combined with home-based exercise education) or control treatment (home-based education). The primary outcome was motor development (gross motor quotient (GMQ), fine motor quotient (FMQ), and total motor quotient (TMQ)). The secondary outcomes were cardiac function and structure, bone quality, physical development, parental anxiety, caregiver burden, and quality of life. Children and their families were assessed before and 1, 3, and 6 months after catheterization; 183 (95.3%) children were included in the primary analysis.

RESULTS

After 6-month treatment, the intervention group significantly increased their motor quotient, which was consistently higher than that of the control group (GMQ p < 0.0001, FMQ p = 0.02, TMQ p < 0.001). The physical developments in height, weight, and circumferences of the upper-arm, chest, and head were also significantly improved by exercise (all p < 0.017). No significant improvements in the bone strength or the cardiac structure and function were found among patients in the intervention group (all p > 0.017). For parents, higher quality of life level (total score p = 0.016) was observed in the intervention group; while effects of exercise on the anxiety (rude score p = 0.159, standard score p = 0.159) or the Zarit caregiver burden scale score (p = 0.404) were non-significant. No adverse events occurred during the study period.

CONCLUSIONS

Customized home-based exercise improved motor development in children with CHD. While the long-term effects of parent training in home-based exercise are unknown, the study results suggest positive outcomes.

Sensor-Based Assessment of Time-of-Day-Dependent Physiological Responses and Physical Performances during a Walking Football Match in Higher-Weight Men

Monitoring key physiological metrics, including heart rate and heart rate variability, has been shown to be of value in exercise science, disease management, and overall health. The purpose of this study was to investigate the diurnal variation of physiological responses and physical performances using digital biomarkers as a precise measurement tool during a walking football match (WFM) in higher-weight men. Nineteen males (mean age: 42.53 ± 12.18 years; BMI: 33.31 ± 4.31 kg·m-2) were engaged in a WFM at two different times of the day. Comprehensive evaluations of physiological parameters (e.g., cardiac autonomic function, lactate, glycemia, and oxygen saturation), along with physical performance, were assessed before, during, and after the match. Overall, there was a significant interaction (time of day x WFM) for mean blood pressure (MBP) (p = 0.007) and glycemia (p = 0.039). Glycemia decreased exclusively in the evening after WFM (p = 0.001), while mean blood pressure did not significantly change. Rating of perceived exertion was significantly higher in the evening than in the morning (p = 0.04), while the heart rate recovery after 1 min (HRR60s) of the match was lower in the evening than in the morning (p = 0.048). Overall, walking football practice seems to be safe, whatever the time of day. Furthermore, HRR60, glycemia, and (MBP) values were lower in the evening compared to the morning, suggesting that evening exercise practice could be safer for individuals with higher weight. The utilization of digital biomarkers for monitoring health status during WFM has been shown to be efficient.

Exercise as Medicine: Evaluation and Prescription for Adults with Congenital Heart Disease

PURPOSE OF REVIEW

Understanding exercise physiology as it relates to adult congenital heart disease (ACHD) can be complex. Here we review fundamental physiologic principles and provide a framework for application to the unique ACHD patient population.

RECENT FINDINGS

ACHD exercise participation has changed dramatically in the last 50 years. A modern approach focuses on exercise principles and individual anatomic and physiologic considerations. With an evolving better understanding of ACHD exercise physiology, we can strategize plans for patients to participate in dynamic and static exercises. Newly developed technologies including wearable devices provide additive information for ACHD providers for further assessment and monitoring. Preparation and assessment for ACHD patients prior to exercise require a thoughtful, personalized approach. Exercise prescriptions can be formulated to adequately meet the needs of our patients.

Cardiorespiratory Fitness and Risk of Cardiovascular Events and Mortality in Middle Age Patients without Known Cardiovascular Disease

BACKGROUND

Low cardiorespiratory fitness is an established risk predictor for chronic non-communicable diseases. We aimed to investigate the prognostic significance of fitness level on the risk of major adverse cardiac events (MACE, the composite of myocardial infarction, stroke, or all-cause death), in a contemporary cohort of middle-aged subjects without cardiovascular disease.

METHODS

Retrospective analysis of patients aged 40-60 years without a history of cardiovascular disease. Degree of fitness was determined according to a graded, maximal treadmill exercise stress testing (EST) time achieved, classified into age- and sex-specific quintiles (Q), and categorized as low (Q1), moderate (Q2-Q4) or high (Q5) fitness groups. A multivariable Cox proportional hazard regression model was used to assess the association of fitness level with the risk of MACE.

RESULTS

A total of 6836 patients were included, of which 44.5% were women, and the mean age was 52 years. Overall, 289 MACE events occurred during a median follow-up of 7 years. Level of fitness was inversely associated with the presence of cardiovascular risk factors. The multivariable adjusted hazard ratio (95% confidence interval) for MACE was 1.65 (1.12-2.44) and 2.17 (1.40-3.38) in those at moderate and low fitness levels, compared to the high-fitness group (reference), respectively. For each decrease of one metabolic equivalent (MET) unit achieved at peak exercise, the relative risk for MACE increased by 18%. The association between low fitness and MACE was not modified by other risk factors (P-for-interaction non-significant).

CONCLUSIONS

Low fitness level, as captured by a maximal treadmill EST, is an independent risk predictor for MACE among middle-age individuals without known cardiovascular disease. The association of low fitness with high burden of cardiometabolic risk factors highlight the importance of lifestyle intervention in this patient population.

Challenges and opportunities for improvement in the management and financing system of Health Promotion Offices in Hungary

Background

One hundred ten Health Promotion Offices (HPOs) have started operating in Hungary in response to public health challenges. Many of them have been active for almost 10 years, yet their operational experience has not been evaluated. The specific objectives of our study were: (1) to describe the current operational and funding system of HPOs, (2) to identify challenges related to the current management and funding practices, and (3) to formulate recommendations for improvement based on gathered experience and international experience.

Design

In order to gain a deeper insight into the operational experience of HPOs, an online survey was conducted with the professional or economic managers of HPOs. A scoping review was carried out to gather international experiences about best practices to formulate recommendations for improvement in developing the operational and financing scheme for HPOs.

Results

We found that current HPO network in Hungary faces three main challenges: a deficient management system, inflexible financing scheme, and unequal ability to purchase or provide services for the population.

Conclusions

Based on the survey complemented by international experiences, we propose the overhaul of the professional management system and switching toa combination of fixed and performance-based financing scheme for the HPOs in Hungary.

The Benefits of a Comprehensive Cardiac Rehabilitation Program for Patients with Acute Coronary Syndrome: A Follow-Up Study

BACKGROUND AND OBJECTIVES

Secondary prevention after acute coronary syndrome (ACS) is essential to reduce cardiovascular mortality and hospital readmission, ensuring patients return to normal with an improved quality of life. Thus, we investigate the benefits of a comprehensive cardiac rehabilitation (CR) program on lifestyle, risk factors and adherence to guideline-directed medical therapy (GDMT) in patients after ACS and myocardial revascularization through coronary artery by-pass grafting (CABG) or percutaneous coronary intervention (PCI).

METHODS

This is a prospective, longitudinal study in consecutive post-CABG or PCI patients after ACS that participated or not in a comprehensive CR. Cardiovascular risk factors, quality of life and adherence to GDMT were analyzed in terms of assessing the benefit of 12 months of comprehensive CR on reaching guidelines secondary prevention targets.

RESULTS

At the inclusion in comprehensive CR of all patients (n = 480), 85% had hypertension; 86% had elevated total cholesterol values; 69% were characterized by metabolic syndrome; 43% were obese; 31% were active smokers and 29% had type 2 diabetes mellitus. Only 26.66% (n = 128) followed the entire program for 12 months. No statistically significant differences in the prescription of GDMT at hospital discharge after myocardial revascularization between the CR (+) group (n = 128) versus CR (-) group (n = 352) (p > 0.05) were observed. After 12 moths, a significant adherence to GDMT in the CR (+) group vs. CR (-) group was recorded, as follows: antiplatelet agents (100% versus 96%, p = 0.001), beta-blockers (99% versus 92%, p = 0.02), ACE inhibitors/ARAB (89% versus 79%, p = 0.04), lipid-lowering drugs (100% versus 89%, p = 0.001). In total, 82% of the CR (+) patients had a significantly higher adherence at GDMT (82% versus 64%, p = 0.001). At 12 moths, the CR (+) group was characterized by significantly lower values than at the inclusion but some values still increased: systolic blood pressure (139.25 + 19.20 mmHg (p < 0.03)), total cholesterol (171.07 + 48.59 mg/dL (p = 0.0001)) and LDL-cholesterol (102.83 + 41.30 mg/dL (p = 0.009)). At the same time, the analysis of psychosocial factors using the HAD questionnaire revealed a statistically significant improvement in anxiety and depression scores: HAD-A score (9.1 ± 3.7 at T0 vs. 7.1 ± 4.2 at T1, p = 0.001) and HAD-D score (7.7 ± 3.19 at T0 vs. 6.4 ± 4.3 at T1, p = 0.003). A multivariable analysis, following GDMT, showed the actual value or information and training of patients regarding optimal cardiovascular risk factor control was independently associated with lower values of systolic blood pressure (R2 = 0.48), diastolic (R2 = 0.38), serum glucose (R2 = 0.48), glycated hemoglobin (R2 = 0.50), total cholesterol (R2 = 0.31), LDL-cholesterol (R2 = 0.30), HDL-cholesterol (R2 = 0.19) and serum triglycerides (R2 = 0.20).

CONCLUSION

The twelve-month participation of post-ACS patients in comprehensive CR resulted in excellent post-revascularization management, as well as good adherence to guideline-directed medical therapy, provided further confirmation of the benefit of secondary prevention. Despite high adherence to drug treatments, targets for blood pressure, total cholesterol and LDL-cholesterol are inadequately achieved. Therefore, in the era of personalized medicine, patients with ACS should benefit from specific, comprehensive cardiovascular recovery programs that contain physiotherapists, psychologists, nutritionists and an experienced cardiologist in cardiovascular rehabilitation.

The moderating role of physical activity on the relationship between work intensity and depressive symptoms among the employees

Our aim was to examine the associations between work intensity and depressive symptoms among the working population, as well as to identify the impact of physical activity (PA) on these relationships. Spearman correlation analysis was conducted to analyze the correlations among work intensity, PA, and depressive symptoms. Working hours and working days were positively correlated with depressive symptoms (r = 0.108, 0.063; all p values were <0.001). Regular PA, exercise time, exercise frequency, and exercise years were negatively correlated with depressive symptoms (r = -0.121, -0.124, -0.152, -0.149; all p values were <0.001) and working days (r = -0.066, -0.050, -0.069, -0.044; all p values were <0.001), working hours (r = -0.113. -0.106, -0.161, -0.123; all p values were <0.001). Working days was positively correlated with working hours (r = 0.512, p < 0.001). Different levels of PA alleviated the effect of working hours or working days on depressive symptoms. Working hours seemed to be more correlated with depressive symptoms than working days. The results suggest that PA at any level could buffer against the effects of work intensity and might prove a helpful strategy for improving mental health issues among employees.

Physical Activity and Sedentary Behavior in Adults from Penafiel, Portugal: A Cross-Sectional Study

The aim of this study was to compare the physical activity (PA) and sedentary behavior (SB) levels of young and middle-aged adults living in and around the municipality of Penafiel and to determine whether they meet PA recommendations. The researchers used the "International Physical Activity Questionnaire" (IPAQ) to measure moderate to vigorous PA and time spent on sedentary behavior (high vs. low). A prospective observational cross-sectional sample of 1105 adults aged 18-63 years, living in the municipality of Penafiel and its surroundings (45% women, 55% men), was used. The results indicated that more than half of the population was inactive (53.8%) and sedentary (54.0%). Men were more likely to be sedentary (59.2%) and inactive (55.6%) than women (inactive: 51.7%, high SB: 47.7%). Regarding daily PA and SB levels, women had higher levels of walks (3.8 ± 2.3; p = 0.034) and vigorous PA (2.2 ± 1.8 min; p = 0.005) per days/week, as well as vigorous PA per minutes/week (75.4 ± 82.1 min; p = 0.034). The time spent on vigorous PA per day was also higher in women (26.2 ± 22.8 min; p = 0.030). However, men had higher values in walking minutes per day (26.3 ± 17.1 min; p = 0.030), SB for weekdays (429.2 ± 141.2 min; p = 0.001), SB for weekends (324.7 ± 163.7 min; p = 0.033) and time spent on SB per minutes/week (2795.6 ± 882.0 min; p = 0.001). The results also showed that the older the adults, the lower the frequency and total time of vigorous PA per week. Young adults (18-28 years) had higher levels of vigorous PA (p = 0.005) than the other age groups (29-39; 40-50 and 51-63 years). Finally, the study found no significant correlation between individual level factors, such as number of children, marital status and monthly income, and PA or SB. Conversely, a significant and negative correlation between SB and levels of PA was found, indicating that the higher the level of PA practice, the lower the SB level. The authors suggest that promoting new PA habits and healthy lifestyles is an important future challenge for sustainability and improving the quality of life in public health.

Extraordinary claims in the literature on high-intensity interval training (HIIT): III. Critical analysis of four foundational arguments from an interdisciplinary lens

Kinesiology aspires to be an integrated, interdisciplinary field that studies human movement from multiple perspectives. However, the main societal deliverables of the field, namely exercise prescriptions and physical activity recommendations, still reflect fragmentation, placing more emphasis on physiological outcomes than on behavioral and other considerations. Recently, researchers have called for the introduction of High-Intensity Interval Training (HIIT) to the domain of public health, based on the argument that HIIT can maximize fitness and health benefits for a fraction of the time recommended by the prevailing model of physical activity in public-health guidelines. Here, we show that an unintended side-effect of arguments underpinning the implementation of HIIT in the domain of public health might have been the exacerbation of segmentation. To highlight the value of interdisciplinarity, four foundational claims in support of HIIT are critiqued by tapping into cognate literatures: (1) the primary reason people do not exercise is lack of time, (2) HIIT is relevant to public health, (3) HIIT is being proposed as merely another option, so there is no basis for controversy, and (4) HIIT is safe and well tolerated. These claims are contradicted by credible lines of evidence. To improve the accuracy and effectiveness of its public claims, kinesiology should remain committed to the ideals of integration and interdisciplinarity.

Chronic Effects of Different Intensities of Interval Training on Hemodynamic, Autonomic and Cardiorespiratory Variables of Physically Active Elderly People

Interval training (IT) is a very efficient method. We aimed to verify the chronic effects of IT with different intensities on hemodynamic, autonomic and cardiorespiratory variables in the elderly. Twenty-four physically active elderly men participated in the study and were randomized into three groups: Training Group A (TG_A, n = 8), Training Group B (TG_B, n = 8) and control group (CG, n = 8). The TG_A and TG_B groups performed 32 sessions (48 h interval). TG_A presented 4 min (55 to 60% of HRmax) and 1 min (70 to 75% of HRmax). The TGB training groups performed the same protocol, but performed 4 min at 45 to 50% HRmax and 1 min at 60 to 65% HRmax. Both training groups performed each set six times, totaling 30 min per session. Assessments were performed pre (baseline) after the 16th and 32nd intervention session. The CG performed only assessments. Hemodynamic, autonomic and cardiorespiratory (estimated VO_2max) variables were evaluated. There were no significant differences between protocols and times (p > 0.05). However, the effect size and percentage delta indicated positive clinical outcomes, indicating favorable responses of IT. IT may be a strategy to improve hemodynamic, autonomic and cardiorespiratory behavior in healthy elderly people.

Electronic textiles: New age of wearable technology for healthcare and fitness solutions

Sedentary lifestyles and evolving work environments have created challenges for global health and cause huge burdens on healthcare and fitness systems. Physical immobility and functional losses due to aging are two main reasons for noncommunicable disease mortality. Smart electronic textiles (e-textiles) have attracted considerable attention because of their potential uses in health monitoring, rehabilitation, and training assessment applications. Interactive textiles integrated with electronic devices and algorithms can be used to gather, process, and digitize data on human body motion in real time for purposes such as electrotherapy, improving blood circulation, and promoting wound healing. This review summarizes research advances on e-textiles designed for wearable healthcare and fitness systems. The significance of e-textiles, key applications, and future demand expectations are addressed in this review. Various health conditions and fitness problems and possible solutions involving the use of multifunctional interactive garments are discussed. A brief discussion of essential materials and basic procedures used to fabricate wearable e-textiles are included. Finally, the current challenges, possible solutions, opportunities, and future perspectives in the area of smart textiles are discussed.

Examining the effects of the COVID-19 pandemic on life through interviews conducted by nursing students: a qualitative study

This study was aimed to determine the effects of the pandemic on life. This is a qualitative descriptive study and data were collected through semi-structured interviews (n = 200). The data were obtained by retrospectively examining the interviews made by the students between January and May 2021. The researchers prepared 'Participant Information Form' and 'Semi-Structured Interview Form', which were utilised as data collection tools during the interviews. The qualitative data acquired from the semi-structured interview using descriptive analysis. In the interviews, nursing students are in the role of interviewers. Participants were determined from among the relatives of the students. The research was structured and reported in accordance with the Consolidated Criteria for Reporting Qualitative Research Checklist. The data acquired regarding the effects of the pandemic on life were conceptualised under three themes (nine sub-themes): the meaning of the pandemic(1), the effects of the pandemic on life(2), and coping with the pandemic(3). The study revealed that the pandemic included individual meanings at levels of emotions (fear, hopelessness, loneliness, despair, and uncertainty) and cognition - behaviour (danger, attention-caution, restriction and awareness).Pandemic resulted in changes in the life routines of the participants, changes in mental and social spheres, and various effects as the effect of the disease such as pain.Spiritual approaches (prayer and positive thinking), as well as social support and healthy lifestyle habits, were the methods used to cope with the pandemic. It is recommended that psychiatric nurses plan and implement individual/social interventions based on a psychosocial approach in order to cope with the short and long-term effects of the pandemic.

The 5 K run in popular fiction: Reading about parkrun and couch to 5 K

Recent years have witnessed great interest in mass-participation running events (1), and organisations such as parkrun and fitness programmes like Couch to 5 K, have been instrumental in enabling participation for inexperienced runners. Concomitant with this has been a number of fictional works which centre on the 5 K run. I contend that exploring fictional texts can offer a fresh take on how movements such as parkrun and Couch to 5 K have entered the popular imagination. The four texts explored are Wake's Saturday Morning Park Run (2020), Park's A Run in the Park (2019), Boleyn's Coming Home to Cariad Cove (2022), and James's I Follow You (2020). The analysis is arranged thematically around the categories of health promotion, individual transformation, and community building. I argue that these texts frequently operate as health promotion tools and can help familiarise would-be runners with how parkrun and Couch to 5 K work.

Sociodemographic Aspects and Healthy Behaviors Associated With Perceived Life Satisfaction in Health Professionals

BACKGROUND

Life satisfaction is a determining factor for the improvement of mental and physical health. Health care workers are a vulnerable population to suffer alterations in the factors that affect life satisfaction. Determining the influence of these factors on quality of life is important for their proper management.

OBJECTIVE

To examine sociodemographic factors and healthy behaviors influencing life satisfaction in Peruvian professionals.

METHODS

A cross-sectional study was conducted with 506 health care workers, who had a mean age of 40.34 years (SD = 10.39). A sociodemographic questionnaire, sleep quality, physical activity, eating habits, and life satisfaction were used. A regression model was fitted with the life satisfaction variable as the dependent variable.

RESULTS

In multivariable analysis, age (β = -.938, P < .01) and perception of poor health status (β = -4.743, P < .001) were found to be associated with lower life satisfaction. On the other hand, higher university education level (β = 1.667, P < .001), absence of smoking (β = 3.202, P < .01), absence of depressive symptoms (β = 3.390, P < .001), interest in daily activities (β = 3.503, P < .05), good sleep quality (β = 1.027, P < .01), a high frequency of physical activity (β = 1.056, P < .01), and healthy eating are variables associated with higher life satisfaction.

CONCLUSION

Sociodemographic aspects such as age and the perception of poor health are associated with lower life satisfaction. On the other hand, healthy behaviors such as absence of smoking, absence of depressive symptoms, interest in daily activities, good quality of sleep, high frequency of physical activity, and a healthy diet were associated with higher life satisfaction.

Epidemiological, mechanistic, and practical bases for assessment of cardiorespiratory fitness and muscle status in adults in healthcare settings

Given their importance in predicting clinical outcomes, cardiorespiratory fitness (CRF) and muscle status can be considered new vital signs. However, they are not routinely evaluated in healthcare settings. Here, we present a comprehensive review of the epidemiological, mechanistic, and practical bases of the evaluation of CRF and muscle status in adults in primary healthcare settings. We highlight the importance of CRF and muscle status as predictors of morbidity and mortality, focusing on their association with cardiovascular and metabolic outcomes. Notably, adults in the best quartile of CRF and muscle status have as low as one-fourth the risk of developing some of the most common chronic metabolic and cardiovascular diseases than those in the poorest quartile. The physiological mechanisms that underlie these epidemiological associations are addressed. These mechanisms include the fact that both CRF and muscle status reflect an integrative response to the body function. Indeed, muscle plays an active role in the development of many diseases by regulating the body's metabolic rate and releasing myokines, which modulate metabolic and cardiovascular functions. We also go over the most relevant techniques for assessing peak oxygen uptake as a surrogate of CRF and muscle strength, mass, and quality as surrogates of muscle status in adults. Finally, a clinical case of a middle-aged adult is discussed to integrate and summarize the practical aspects of the information presented throughout. Their clinical importance, the ease with which we can assess CRF and muscle status using affordable techniques, and the availability of reference values, justify their routine evaluation in adults across primary healthcare settings.

Investigating Factors Associated with Fear of Falling in Community-Dwelling Older Adults through Structural Equation Modeling Analysis: A Cross-Sectional Study

The scientific literature mentions the existence of factors associated with fear of falling in older adults. However, the direct and indirect paths of its predictors have not yet been fully explored. This study aimed to analyze the socioeconomic, clinical, and health factors directly and indirectly associated with fear of falling in community-dwelling older adults. This is a cross-sectional study conducted in older adults (n = 410 - 70.11 ± 7.22 years). Clinical and health-condition data were collected, as were data on fear of falling using the Falls Efficacy Scale International-Brazil (FES-I Brazil). It was found that being female and having a higher number of self-reported morbidities, worse physical performance, and a higher number of depressive symptoms were directly associated with greater fear of falling. Regarding indirect associations, physical inactivity, mediated by a greater number of morbidities, worse physical performance, and a greater number of depressive symptoms, was associated with greater fear of falling. In addition, worse self-rated health, mediated by a greater number of depressive symptoms, as well as older age, mediated by worse physical performance, were associated with the outcome. This study provides information on the predictors directly and indirectly associated with fear of falling, expanding current understanding of this relationship.

"WOT" Do We Know and Do About Physical Activity of Children and Adolescents With Disabilities? A SWOT-Oriented Synthesis of Para Report Cards

The purpose was to synthesize information gathered from the interpretation and conclusion sections of the Global Matrix of Para Report Cards on the physical activity of children and adolescents with disabilities. The synthesis was based on the strengths, weaknesses, opportunities, and threats framework. The procedure consisted of three stages: (a) the application of the International Classification of Functioning, Disability and Health as the theoretical framework; (b) identifying and aligning Global Matrix indicators and benchmarks with the International Classification of Functioning, Disability and Health components through a Delphi approach; and (c) using content analysis to identify themes from specific report cards. Outcomes reveal that further attention toward including children and adolescents with disabilities in fitness assessments is needed as well as adapted assessment methods. Program availability, equipment and facilities, and professional training emerged as strengths but need further development to overcome weaknesses. Paralympic inspiration was an opportunity, whereas extreme weather conditions presented potential threats to physical activity participation among children and adolescents with disabilities.

Chronic Effects of Different Types of Neuromuscular Training on Hemodynamic Responses Estimated VO2max, and Walking Performance in Older People

This paper investigated the effects over time of different forms of neuromuscular training on hemodynamic responses, the estimated VO_2max, and walking performance. 105 older adults were randomly organized into three groups: RG_A, RG_B, and the Control Group (CG). RG_A and RG_B did 4 weeks of adaptation phase training and 12 weeks of intervention with different loads: moderate loads for RG_B. and higher loads for RG_A. A pre- and post-evaluation of the resting heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), double product (DP), estimated VO_2max, and walking performance were assessed. Significant differences were observed for SBP, DBP, HR, and DP. For SBP, a post-evaluation reduction was observed only in RG_A (p = 0.007) and when comparing RG_A with the Control Group (p < 0.000). For the absolute VO_2max, a significant improvement was seen in RG_B compared to RG_A (p = 0.037) and CG (p < 0.000). For the relative VO_2max, RG_B scored significantly higher than RG_A (p < 0.000) and CG (p < 0.000), post-intervention. For the walk test, a significant reduction in completion times was observed for RG_A (p = 0.027) and RG_B (p < 0.000), and for RG_B compared to RG_A (p = 0.000) and CG (p < 0.000). Resistance training can be an excellent strategy for hemodynamic and cardiorespiratory improvement in the elderly.

The interplay among body weight, blood pressure, and cardiorespiratory fitness in predicting atrial fibrillation

BACKGROUND

Hypertension, obesity, and low cardiorespiratory fitness (CRF) are known risk predictors for the development of atrial fibrillation (AF) that often interrelate with each other. We examined the interplay of these 3 risk indicators with the occurrence of AF in patients without known cardiovascular disease.

METHODS

A retrospective analysis of 13,042 patients underwent exercise stress testing (EST). The occurrence of AF during the median follow-up period of 6.8 years was investigated in relation to the presence of obesity (body mass index ≥30 kg/m²), hypertension (blood pressure ≥140/90 mmHg or history of hypertension), or low CRF (exercise capacity <8 metabolic equivalents). Cox proportional hazards models were used to evaluate the individual and combined association between the 3 risk indicators and AF.

RESULTS

The mean age of the study population was 58 ± 9 years; 49% were women. AF occurred in 499 patients (3.8%). Obesity [hazard ratio (95% confidence interval)], 1.36 (1.12-1.65), hypertension, 1.47 (1.19-1.82), and low CRF, 1.32 (1.06-1.64), were independent risk predictors for AF after multivariable adjustment, including after adjusting for each other and also when the risk predictors were analyzed as continuous variables. In a combined model, a gradual increase in the risk of AF was observed, reaching an adjusted hazard ratio of 2.53 (1.77-3.62) in those with all 3 compared with neither risk indicators. P-for-interaction between hypertension and obesity, or hypertension and low CRF was nonsignificant.

CONCLUSIONS

Obesity, low CRF, and hypertension are independently associated with an excess risk of developing AF in patients without known cardiovascular disease, both individually and more so when coexisting together.

Associations of physical activity intensity with incident cardiovascular diseases and mortality among 366,566 UK adults

BACKGROUND

The associations of the proportion of vigorous physical activity (VPA) to moderate to vigorous physical activity (MVPA) with incident cardiovascular disease (CVD) and all-cause mortality are unclear.

METHODS

The present study included 366,566 participants (aged 40-69 years) without baseline CVD from the UK biobank during 2006 to 2010. Cox regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for risks of outcomes.

RESULTS

During a median 11.8 years of follow-up, among 366,566 participants (mean age [SD]: 56.0 [8.1]), 31,894 incident CVD and 19,823 total deaths were documented. Compared with no VPA, 0%-30% of VPA to MVPA was associated with 12% and 19% lower risks of incident CVD (HR, 0.88 [95% CI, 0.86-0.91]) and all-cause mortality (HR, 0.81 [95% CI, 0.78-0.84]), respectively. Furthermore, we found that the maximum reduction of risks of incident CVD and all-cause mortality occurred at performing approximately 30% of VPA to MVPA (P < 0.001). Compared with participants reporting the lowest levels of MVPA (moderate physical activity [MPA], 0-150 min/week; VPA, 0-75 min/week), those performing 150-300 min/week of MPA and ≥ 150 min/week of VPA experienced the lowest risk of incident CVD (HR, 0.87 [95% CI, 0.79-0.95]) and all-cause mortality (HR, 0.71 [95% CI, 0.63-0.80]). Interestingly, we found that smokers yielded more cardiovascular benefits than non-smokers by performing a higher volume of VPA.

CONCLUSIONS

Comparing with UK adults reporting no VPA, engaging in 30% of VPA was associated with the lowest risk of incident CVD and all-cause mortality.

Assessment of Exercise Intensity for Uphill Walking in Healthy Adults Performed Indoors and Outdoors

BACKGROUND

Borg's rating of perceived exertion (BRPE) scale is a simple, but subjective tool to grade physical strain during exercise. As a result, it is widely used for the prescription of exercise intensity, especially for cardiovascular disease prevention. The purpose of this study was to assess and compare relationships between BRPE and physiological measures of exercise intensity during uphill walking indoors and outdoors.

METHODS

134 healthy participants [median age: 56 years (IQR 52-63)] completed a maximal graded walking test indoors on a treadmill using the modified Bruce protocol, and a submaximal 1 km outdoor uphill cardio-trekking test (1 km CTT). Heart rate (HR) and oxygen consumption (V̇O₂) were continuously measured throughout both tests. BRPE was simultaneously assessed at the end of each increment on the treadmill, while the maximal BRPE value was noted at the end of the 1 km CTT.

RESULTS

On the treadmill, BRPE correlated very high with relative HR (%HR_max) (ρ = 0.88, p < 0.001) and V̇O₂ (%V̇O_2max) (ρ = 0.89, p < 0.001). During the 1 km CTT, a small correlation between BRPE and %HR_max (ρ = 0.24, p < 0.05), respectively %V̇O_2max was found (ρ = 0.24, p < 0.05).

CONCLUSIONS

Criterion validity of BRPE during uphill walking depends on the environment and is higher during a treadmill test compared to a natural environment. Adding sensor-based, objective exercise-intensity parameters such as HR holds promise to improve intensity prescription and health safety during uphill walking in a natural environment.

Factors Associated with Outdoor Winter Walking in Older Adults: A Scoping Review

The purpose of this study was to identify internal and external factors associated with outdoor winter walking in older adults. In this scoping review, 12 databases were searched. Inclusion criteria included English language, focus on adults 65 years of age or older, and evaluation of factors associated with outdoor winter walking. Two authors screened titles/abstracts and full text. Conflicts were resolved by consensus. Data were extracted, organized into tables, and summarized as pertaining to barriers/facilitators and internal/external factors associated with outdoor winter walking. A total of 6,843 articles were identified, 1,898 duplicates were removed, 4,789 were excluded during title/abstract screening, and 148 were excluded during full-text review. Eight studies were included. Four categories of factors affecting outdoor winter walking in older adults were identified: adverse weather conditions, physical environment, physical function, and perceptions relating to winter walking conditions. Rehabilitation and exercise professionals can use the results to educate their clients and implement the facilitators of and alternatives and solutions to barriers to outdoor winter walking.

Validity and reproducibility of a method to estimate cardiorespiratory fitness in college adults

Introduction: Cardiorespiratory fitness is a predictor of cardiovascular and all-cause mortality. Its assessment in different groups has clinical and public health usefulness. Objective: To evaluate the validity and reproducibility of a no-exercise method [National Aeronautics and Space Administration (NASA) method] to estimate the maximum oxygen consumption (VO2máx) in college adults. Materials and methods: This study included 94 healthy individuals of both sexes (18-55 years). The gold standard was ergospirometry. The validity and reproducibility were evaluated with the intraclass correlation coefficient (ICC) and the Bland-Altman method. Results: Among the participants, we found a mean age of 30.54 ± 9.33 years and a VO2máx of 41.29 ± 9.54 ml O2.kg-1.min-1; 48.9 % were women. A mean difference of VO2máx between ergospirometry and that estimated by the NASA method of 3.41 ± 5.64 ml O2.kg-1.min-1 was found. The concordance between the two methods was good, with an ICC of 0.858 (CI95% 0.672-0.926). The percentage of error was 29.70 %. The reproducibility of the two estimates by the NASA method was excellent, with an ICC of 0.986 (CI95% 0.927-0.995). Conclusions: The NASA method is valid and reproducible to estimate VO2máx in college adults. In addition, it is safe and easy to apply. Estimating cardiorespiratory fitness is recommended to improve screening in cardiometabolic risk programs and to implement timely interventions.

Clinical associations between exercise and lipoproteins

PURPOSE OF REVIEW

One of the major concerns in global health is the deteriorating control of dyslipidemia (DLD), which is a very strong modifiable risk factor for untoward cardiovascular disease (CVD) outcomes. It serves as a foundation for atherosclerotic lesions that can be destabilized by co-inflammatory processes leading to distal clot migration and other related CVD events. There are many misconceptions regarding the management of DLD. Many health sectors advocate for weight loss without a clear-cut target to achieve better CVD outcomes. There is growing evidence that exercise training compliance regardless of weight change is a more reliable indicator of favorable outcomes. This review is intended to understand the relationship between exercise training, lipoprotein readings, and with CVD and all-cause morbidity and mortality.

RECENT FINDINGS

Aerobic exercise training (aET) and resistance exercise training (rET) increase cardiorespiratory fitness (CRF) and muscular strength (MusS), respectively. Regardless of weight loss, aET and rET are both known to independently reduce mortality possibly partly through improvement of lipid profiles. Of the two modes of exercise, rET has propensity for enhanced compliance because of its significant lipid and mortality-attenuating effect even with just brief exercise sessions. However, there are several studies showing that participation in both modes of exercise causes more pronounced improvements in DLD and CVD-related mortality compared with either mode of exercise training alone. In addition, Lipoprotein-a [Lp(a)] has been increasingly acknowledged to be atherogenic because of its LDL core. The close proximity of Lp(a) with macrophages triggers the development of atheromas, plaque formation, and growth. This causes a cascade of inflammatory processes that increase the development of ischemic CVD and calcific aortic valve stenosis. Although exercise training is known to reduce plasma LDL-C levels, it has no direct effect on Lp(a) levels as the latter lipoprotein is not influenced by motion nor exercise. Reviews of multiple studies lead us to infer that exercise training may potentially have an indirect impact on Lp(a) attenuation because of the ability of exercise training to inhibit Proprotein Convertase Subtisilin/Kexin type-9 (PCSK-9), as some studies using pharmacologic therapy with PCSK-9 inhibitors were able to show a concomitant decrease in Lp(a) levels.

SUMMARY

It is clear that normal-to-overweight populations who are highly active have better CVD outcomes and lipid profiles than their sedentary counterparts, and those who were underweight and unfit fared much worse. This allows us to take a more precise approach in the management of DLD rather than plainly focusing on gross weight in patients. Exercise training certainly has beneficial impact on longevity owing to its advantageous effect on lipoprotein levels and particle size. As such, reputable health societies, such as the ESC, ACC, and AHA have prescribed the ideal exercise training regimen, which have noticeable similarities. Increasing the use of wearable devices may help improve our ability to prescribe, quantify, and precisely track physical activity in our continuing efforts to combat increasing morbidity related to unhealthy lifestyles and inactivity.

Barriers to and motives for engagement in an exercise-based cardiac rehabilitation programme in Ireland: a qualitative study

Background

Insufficient physical activity (PA) is a leading risk factor for premature death worldwide. Ireland’s public healthcare system, the Health Service Executive (HSE), has supported the development of the National Exercise Referral Framework (NERF) to tackle low levels of PA amongst those with non-communicable diseases (NCDs). ‘NERF centres’ are medically supervised PA programmes across Ireland that have established referral pathways with local hospitals and general practitioners. ULMedX is one such NERF centre offering exercise-based cardiac rehabilitation (EBCR) with the aim of intervention development to reduce early drop-out and maximise adherence for optimal health benefits.

Aim

The purpose of this research was to identify the major factors influencing participants’ adherence and early drop-out at ULMedX. Exploring areas for future development were also prioritised.

Design & setting

Qualitative interviews were conducted with long-term attenders and people who have dropped out (PWDO) from ULMedX.

Methods

Guided by the Theory of Planned Behaviour the 1–1 semi-structured interviews were performed, transcribed, and evaluated through thematic analysis.

Results

Analysis was performed on 14 participants (50% female; mean age 67.3 years), comprising long-term attenders (n = 7; 13-month duration, 64% of classes) and PWDO (n = 7; 2.8-month duration, 22% of classes). Three major factors affecting adherence and drop-out were identified: social support, perceived outcomes from participation and practical barriers to attendance. Areas for future development included the provision of evening and advanced classes, psychological support, more exercise variety, more educational seminars and new members start as their own group.

Conclusion

The findings suggest participants at ULMedX are more likely to have had a better experience and commit to the programme if they believed involvement would benefit their physical and mental health, increase their exercise motivation by engendering a positive attitude to exercise, and that the ability to attend was within their control. Future interventions at ULMedX should have their structures centred around these motives for engagement. ULMedX should also test the participant recommendations to overcome the common barriers to adherence.
