Abstract: Stress exposure may undermine exercisers' capability to self-regulate their exercise behaviour. This longitudinal study examined the interplay between perceived stress, exercise self-regulation (assessment of action and coping planning) and participation in vigorous exercise in vocational students. Moreover, this study examined whether high exercise self-regulation moderates the assumed negative relationship between stress and exercise. A s le of 580 physically active vocational students ([Formula: see text] ± s 17.8 ± 1.3 years, 33.8% girls) was assessed. All participants completed two identical validated questionnaires assessing stress, exercise self-regulation and exercise with a span of 10 months in between survey completion periods. The cross-sectional analyses show that high exercise self-regulation attenuated the assumed negative relationship between stress and exercise. In the longitudinal analyses, however, only a non-significant trend was found. Significant longitudinal relationships existed between exercise self-regulation and exercise involvement. Latent difference score models revealed that a drop in the exercise self-regulation was associated with a concurrent decrease in exercise participation. Cross-lagged panel analyses showed that high exercise self-regulation levels positively predicted exercise behaviour, but an inverse relationship was not supported. The findings suggested that higher exercise self-regulation levels were positively associated with future exercise involvement in currently active adolescents. While partial support was found that exercise self-regulation moderated the influence of stress on exercise, the findings demonstrated that higher exercise self-regulation levels had a positive impact on future exercise involvement in already active in iduals.

Abstract: This study examined a cognitive stress-moderation model that posits that the harmful effects of chronic stress are decreased in police officers who perceive high levels of physical fitness. It also determined whether the stress-buffering effect of perceived fitness is influenced by officers' self-reported sleep. A total of 460 police officers (n=116 females, n=344 males, mean age: M=40.7 SD=9.7) rated their physical fitness and completed a battery of self-report stress, mental health, and sleep questionnaires. Three-way analyses of covariance were performed to examine whether officers' self-reported mental health status depends on the interaction between stress, perceived fitness and sleep. Highly stressed officers perceived lower mental health and fitness and were overrepresented in the group of poor sleepers. Officers with high fitness self-reports revealed increased mental health and reported good sleep. In contrast, poor sleepers scored lower on the mental health index. High stress was more closely related to low mental health among poor sleepers. Most importantly, perceived fitness revealed a stress-buffering effect, but only among officers who reported good sleep. High perceived fitness and good sleep operate as stress resilience resources among police officers. The findings suggest that multimodal programs including stress management, sleep hygiene and fitness training are essential components of workplace health promotion in the police force.

Abstract: Background: Yoga may help adults of all fitness levels increase their physical activity and decrease their cardiovascular disease risk. Aim: To determine if arterial stiffness is lower (beneficial) in yoga versus non-yoga participants. Method: This cross-sectional study included 202 yoga (48.4 + 14.1 years, 81% female) and 181 (42.8 + 14.1 years, 44% female) non-yoga participants. The primary outcome was carotid–femoral pulse wave velocity (cfPWV). The two groups were compared using analysis of covariance with adjustments for demographic (age and sex), hemodynamic (mean arterial pressure and heart rate), lifestyle (physical activity levels, sedentary behaviour, smoking status and perceived stress score) and cardiometabolic (waist-to-hip ratio, total cholesterol and fasting glucose) factors. Results: Following adjustments, cfPWV was significantly lower in yoga compared to non-yoga participants with a mean difference: −0.28 m.s−1, (95% CI = −0.55 to 0.08). Conclusion: At a population level, yoga participation may assist with decreasing the risk of cardiovascular disease in adults.

Abstract: Physical activity (PA) participation was substantially reduced at the start of the COVID-19 pandemic. The purpose of this study was to assess the association between PA, mental health, and wellbeing during and following the easing of COVID-19 restrictions in the United Kingdom (UK) and New Zealand (NZ). In this study, 3363 adults completed online surveys within 2–6 weeks of initial COVID-19 restrictions (April/May 2020) and once restrictions to human movement had been eased. Outcome measures included the International Physical Activity Questionnaire Short-Form, Depression Anxiety and Stress Scale-9 (mental health) and World Health Organisation-5 Wellbeing Index. There were no differences in PA, mental health or wellbeing between timepoints (p 0.05). In iduals engaging in moderate or high volume of PA had significantly better mental health (−1.1 and −1.7 units, respectively) and wellbeing (11.4 and 18.6 units, respectively) than in iduals who engaged in low PA (p 0.001). Mental health was better once COVID-19 restrictions were eased (p 0.001). NZ had better mental health and wellbeing than the UK (p 0.001). Participation in moderate-to-high volumes of PA was associated with better mental health and wellbeing, both during and following periods of COVID-19 containment, compared to participation in low volumes of PA. Where applicable, during the current or future pandemic(s), moderate-to-high volumes of PA should be encouraged.

Abstract: Strategies implemented worldwide to contain COVID-19 outbreaks varied in severity across different countries, and established a new normal for work and school life (i.e., from home) for many people, reducing opportunities for physical activity. Positive relationships of physical activity with both mental and physical health are well recognised, and therefore the aim was to ascertain how New Zealand’s lockdown restrictions impacted physical activity, mental health and wellbeing. Participants (n = 4007 mean ± SD: age 46.5 ± 14.7 years, 72% female, 80.7% New Zealand European) completed (10–26 April 2020) an online amalgamated survey (Qualtrics): International Physical Activity Questionnaire: Short Form Depression, Anxiety and Stress Scale-9 World Health Organisation-Five Well-Being Index Stages of Change Scale. Positive dose–response relationships between physical activity levels and wellbeing scores were demonstrated for estimates that were unadjusted (moderate activity OR 3.79, CI 2.88–4.92 high activity OR 8.04, CI 6.07–10.7) and adjusted (confounding variables: age, gender, socioeconomic status, time sitting and co-morbidities) (moderate activity 1.57, CI 1.11–2.52 high activity 2.85, CI 1.97–4.14). The study results support previous research demonstrating beneficial effects of regular physical activity on mental health and wellbeing. Governments may use these results to promote meeting physical activity guidelines in order to protect mental health and wellbeing during the ongoing COVID-19 restrictions and future pandemics.

Abstract: This study examines how students who met the current recommendations for vigorous physical activity (VPA) of the American College of Sports Medicine (ACSM) and the Centers of Disease Control and Prevention (CDC) differ from peers who did not reach these standards with regard to self-reported burnout, before and after controlling for light physical activity and moderate physical activity. A s le of 144 vocational students ( M age = 16.2 years, SD = 1.13, 98 males) completed the International Physical Activity Questionnaire, the Shirom-Melamed Burnout Measure, and the School Burnout Inventory. Bivariate correlations revealed that only VPA was associated with reduced burnout. Both the ACSM and CDC guidelines were useful to identify significant differences in burnout symptoms between students who met versus did not meet the standards. Health policy makers should develop strategies to integrate more VPA into the lives of adolescent students so as to reach a minimum of 60 min per week.

Abstract: Elliot, CA, Hamlin, MJ, and Lizamore, CA. Validity and reliability of the Hexoskin wearable biometric vest during maximal aerobic power testing in elite cyclists. J Strength Cond Res 33(5): 1437–1444, 2019—The purpose of this study was to investigate the validity and reliability of the Hexoskin vest for measuring respiration and heart rate (HR) in elite cyclists during a progressive test to exhaustion. Ten male elite cyclists (age 18–52 yrs, height 179.3 ± 6.0 cm, body mass 73.2 ± 9.1 kg, V o 2 max 60.7 ± 7.8 ml·kg·min −1 , mean ± SD ) conducted a maximal aerobic cycle ergometer test using a r ed protocol (starting at 100 W with 25 W increments each min to failure) during 2 separate occasions over a 3–4-day period. Compared with the criterion measure (MetaMax 3B) the Hexoskin vest showed mainly small typical errors (1.3–6.2%) for HR and breathing frequency ( f ), but larger typical errors (9.5–19.6%) for minute ventilation (V E ) during the progressive test to exhaustion. The typical error indicating the reliability of the Hexoskin vest at moderate-intensity exercise between tests was small for HR (2.6–2.9%) and f (2.5–3.2%) but slightly larger for V E (5.3–7.9%). We conclude that the Hexoskin vest is sufficiently valid and reliable for measurements of HR and f in elite athletes during high-intensity cycling but the calculated V E value by the Hexoskin vest produced during such exercise should be used with caution because of the lower validity and reliability of this variable.

Abstract: The rising incidence of non-communicable diseases in western countries is being driven by poor lifestyle choices, including increasingly inadequate physical activity. The aim of this study was to quantify the effectiveness of a physical activity primary care intervention named the 'Green Prescription' on changes in physical activity levels 2-3 year's following original prescription. A retrospective study design using a telephone interview. Physical activity and health information was gathered from participants in June-September 2015, who were originally prescribed a primary care physical activity intervention 2-3 years ago. Respondents were classified as either having completed the programme (adherence group, n = 91) or having not completed the programme (non-adherence group, n = 56). Participants who had completed the programme within the past 2-3 years reported an additional 64 min (95% CI = 16-110) of total physical activity per week compared to those who had dropped out. Forty-two percent of participants in the adherence group reported increased physical activity levels after receiving the Green Prescription compared to 29% in the non-adherence group. The adherence group were less likely to be sedentary (odds ratio 0.7, 95% CI = 0.5-0.9) and more likely to meet the current physical activity guidelines of at least 150 min of physical activity per week (OR = 1.1, 95% CI = 1.0-1.3). The findings indicate a long-term benefit is likely to participants who completed Green Prescription.

Abstract: To investigate the effects of 4 weeks high-intensity interval training in hypoxia on aerobic and anaerobic performance of 3-on-3 basketball players. In a randomised controlled trial, 15 female basketballers completed eight 1-h high-intensity training sessions in either normobaric hypoxia (hypoxic group n = 8, altitude 3052 m) or normoxia (normoxic group n = 7, sea-level). After training, the hypoxic group increased their 1-min all-out shuttle run distance by 2.5% ± 2.3% (mean ± 95% CI, d = 0.83, P = 0.04), compared to the normoxic group 0.2% ± 2.3% ( d = 0.06, P = 0.8), with the difference between groups being clinically worthwhile but not statistically significant ( d = 0.77, P = 0.1). Distance covered in the Yo-Yo intermittent recovery test tended to increase in the hypoxic (32.5% ± 39.3%, d = 1.0, P = 0.1) but not normoxic group (0.3% ± 24.5%, d = 0.08, P = 0.9), with a non-significant change between groups ( d = 0.9, P = 0.2). Compared to normoxia, the hypoxic group significantly increased subjective markers of stress ( d = 0.53, P = 0.005), fatigue ( d = 0.43, P = 0.005), and muscle soreness ( d = 0.46, P = 0.01), which resulted in a lower perceived training performance in the hypoxic compared to the normoxic group ( d = 0.68, P = 0.001). High-intensity interval training under hypoxic conditions likely improved 1-min all-out shuttle run ability in female basketball 3-on-3 players but also increased subjective markers of stress and fatigue which must be taken into consideration when prescribing such training.
