How does physical activity improve adolescent resilience? Serial indirect effects via self-efficacy and basic psychological needs.

Background: Resilience is vital for improving mental health and well-being during adolescence, which is an important yet vulnerable period. Previous research has indicated that physical activity enhances individual resilience. However, limited studies have examined underlying psychological mechanisms between them. The current study aimed to investigate the effect of physical activity on adolescent resilience via self-efficacy and basic psychological needs. Methods: A cross-sectional survey was conducted with 1,732 high school students aged 16 to 20 years old (mean age: 16.51 ± 0.77 years), with nearly equal number of boys (47.63%) and girls (52.37%). They each completed the Physical Exercise Questionnaire, Basic Psychological Needs in Exercise Scale, General Self-Efficacy Scale, and Resilience Scale, respectively. A serial indirect model was constructed to examine how physical activity influences resilience. Results: Structural equation model analysis revealed that physical activity significantly and directly predicted resilience. When self-efficacy and basic psychological needs were included in the model, both direct and indirect effects were observed. Specifically, the positive relationship between physical activity and resilience was partially mediated by self-efficacy and basic psychological needs. In addition, basic psychological needs and self-efficacy were found to serially mediate the direct relathonship between physical activity and resilience. Conclusions: The present study provides novel theoretical insights into sports psychology by establishing a link between basic psychological needs and self-efficacy. The findings have implications for school administrators and physical education instructors in designing targeted interventions to promote adolescent resilience. These interventions may involve creating supportive environment conductive to fulfilling students' basic psychological needs, implementing strategies to enhance self-efficacy beliefs, and providing opportunities for skill development and mastery experiences in sports and physical activities.

Comparative effectiveness of school-based exercise interventions on physical fitness in children and adolescents: a systematic review and network meta-analysis.

Background: Schools provide a favorable setting for health education, however, the most effective school-based exercise mode for improving physical fitness remains unclear. This network meta-analysis was designed to assess and rank the comparative efficacy of six exercise modalities on physical fitness indicators in a school-based setting. Methods: An online search of the Web of Science, PubMed, SPORTDiscus, and Scopus databases was conducted. Randomized and quasi-randomized controlled trials were considered. Outcomes included measures of anthropometry and body composition, muscular fitness, and cardiorespiratory fitness. Data were pooled with a random effects model using the frequentist framework. Results: A total of 66 studies with 8,578 participants (48% girls) were included. High-intensity interval training was the most effective intervention reducing body mass index (mean difference (MD) = -0.60 kg·m-2, 95% confidence interval (95%CI) = -1.04 to -0.15, p = 0.009), elevating VO2max (MD = 3.59 mL·kg-1·min-1, 95% CI = 2.45 to 4.74, p < 0.001), and 20-meter sprint performance (MD = -0.35 s, 95% CI = -0.55 to -0.14, p = 0.001). Aerobic training had the highest probability of reducing waist circumference (standardized mean difference (SMD) = -0.60, 95% CI = -0.88 to -0.32, p < 0.001). Active video games emerged as a promising modality for improving countermovement jump (MD = 2.43 cm, 95% CI = 0.06 to 4.80, p = 0.041) and shuttle running performance (SMD = 0.86, 95% CI = 0.29 to 1.43, p = 0.003). Strength training was the best exercise mode for improving standing long jump performance (SMD = 1.03, 95% CI = 0.07 to 1.98, p = 0.035) while combined training was rated the first for decreasing body fat percent (MD = -2.56%, 95% CI = -4.73 to -0.40, p = 0.022) and increasing push-up repetitions (SMD = 3.59, 95% CI = 0.81 to 6.37, p = 0.012). Conclusion: School-based exercise interventions have multiple effects on physical fitness. The findings of this study will help to inform physical education teachers and coaches how best to deliver exercise programs in a school setting. Since the study was limited by the original research, the conclusions will require further verification using high-quality randomized controlled trials.

Effect of Long-term Exercise Therapy on Motor Symptoms in Parkinson Disease Patients: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

OBJECTIVES: The aims of the study were to assess the effectiveness of long-term exercise therapy (≥12 wks) for patients with Parkinson disease and to derive specific suggestions on how the motor symptom improvements can be optimized by exercise type and exercise dose. DESIGN: The PubMed, Web of Science, Cochrane Central Register, Embase, Scopus, and CNKI databases were searched up to January 2021 for randomized controlled trials focusing on the effects of long-term exercise for Parkinson disease. Two researchers independently evaluated the quality of papers using the PEDro scale. Twenty-six studies with a total of 1243 participants were included. RESULTS: Tai Chi, resistance training, and dance provide significant improvements in physical function and functional mobility. Furthermore, Tai Chi and dance result in balance benefits. However, walking capacity outcomes did not improve after Tai Chi and resistance training but did improve after dance. With an increase in the intervention duration or length of each session, the effect sizes of exercise on these outcomes increased; higher benefits of exercise on these outcomes were observed at a frequency of 2 times/wk. CONCLUSIONS: Long-term exercise therapy is an effective treatment for improving motor symptoms, with dance being an ideal exercise choice.

The mediating role of resilience in the effects of physical exercise on college students' negative emotions during the COVID-19 epidemic.

Due to its suddenness and unpredictability, COVID-19 caused strife and effects on public mental health, resulting in a surge of negative emotions. The study explores the relationship between physical exercise and negative emotions in home-based college students during the COVID-19 epidemic, as well as the mediating role of resilience, thus providing a new basis for understanding the role of physical exercise in improving negative emotions in college students; A total of 1214 college students were investigated with the Physical Exercise Questionnaire, Negative Emotion Scale and Resilience Scale; Both physical exercise and resilience were significantly negatively correlated with negative emotions in college students (r = - 0.25, - 0.33, P < 0.001), and there was a significant positive correlation between physical exercise and resilience (r = 0.47, P < 0.001). Physical exercise had a direct effect on the negative emotions of college students (ß = - 0.14, P < 0.001). Resilience had a partial mediating effect between physical exercise and the negative emotions of the college students, with a mediating effect value of 0.14 and a mediating effect contribution rate of 50.00%; The study found that physical exercise not only directly affected the negative emotions of college students but also improved their resilience by slowing down their negative emotions and promoting their mental health.
