Article tests a hypothesized path model of Theory of Planned Behavior (TPB) variables (i.e., attitude toward behavior, subjective norm, perceived behavioral control, and intention) with physical activity (PA) and depressive symptoms. The findings support the theoretical tenets of TPB and provide empirical evidence of the psychosocial mechanism of PA and depressive symptoms in Chinese adolescents. It suggests that building PA intervention strategies while considering the TPB framework may promote adolescents’ physical and mental health.

Article investigating the effect of intense and tapering training periods using different exercise modalities (i.e., Randori – grip dispute practice without throwing technique, Uchi-komi – technique repetition training, and sprinting) on rating of perceived exertion (RPE), well-being indices, recovery state, and physical enjoyment in judo athletes.

This article presents a systematic review and meta-analysis is to provide an accurate description of the effect of Ramadan observance on sleep duration, sleep quality, daily nap duration, and daytime sleepiness in athletes and physically active individuals.

This article examines the potential mediating role of perceived motor skill competence on relationships between actual ball skills and children’s physical activity (PA) and PA enjoyment. Correlation analyses showed positive relationships among the study variables. The findings highlight that ball skills significantly impact students’ perceived competence, positively and indirectly affecting their PA and PA enjoyment.

Article presents a qualitative-based study evaluating how youth apply learned water safety concepts when posed with a hypothetical aquatic scenario.

Article examining the influence of six goal orientations on physical activity (PA) and physical fitness (PF) in high school students in China using the latest 3 × 2 achievement goal model. Results show fostering self- and other-approach-oriented environments with developmentally appropriate content in physical education may have implications for enhancing high school students’ PA and PF.

This article examines the impact of the pandemic on the physical activity and play behavior of U.S. children and to provide evidence based recommendations to improve their physical activity.

Article investigates the assumption that the oxygen demand remains constant throughout a bout of exercise.

This article presents a study with the aim of examining the effect of different naps opportunities’ durations during Ramadan on performance of short-duration repetitive maximal exercise and perception of effort.

This article investigates the associations between fundamental motor skills (FMS), health-related fitness (HRF) and physical activity (PA) during middle childhood and examines whether HRF serves as a mediator in these pathways. The behavioral mechanism (e.g., maintaining appropriate levels of HRF) provides meaningful insights to understand the obesity trajectory during middle childhood.

Article examines the effects of a jump rope-based physical activity afterschool program on middle school students’ physical fitness. This article belongs to the special issue Physical Activity, Sedentary Behaviour and Health Interventions in Children and Adolescents.

The article highlights a study aimed (1) to examine the relations between different doses of physical activity (PA), light PA (LPA), moderate PA (MPA), and vigorous PA (VPA), academic self-efficacy, and depression among adolescents, and (2) to investigate the direct and indirect relations of various doses of PA to depression through academic self-efficacy among middle school adolescents. Findings of this study indicated that academic self-efficacy regulates adolescents’ depression. Tailoring different intensities of PA benefits adolescents’ academic self-efficacy by framing the positive and supportive environment in schools, which can potentially reduce the prevalence of depression during adolescence.

The article highlights a study meant to examine the relationships between school-based sedentary behavior, physical activity, and health-related outcomes, including cardiorespiratory fitness, weight status, and health-related quality of life (HRQOL) among Hispanic children. Sedentary behavior was negatively correlated with cardiorespiratory fitness and HRQOL but positively associated with weight status. MVPA was positively correlated with cardiorespiratory fitness and HRQOL, but negatively associated with weight status and sedentary behavior. Multiple regressions demonstrated that sedentary behavior significantly predicted cardiorespiratory fitness and weight status, whereas MVPA significantly predicted HRQOL.

Article presents a study examining the effect of sex-specific resistance exercise (RE)-induced hormonal response on mitochondrial dynamics and mitophagy after muscle damage in untrained men and women.

This article presents a study that examined the relationship between psychometric status, neuromuscular, and biochemical markers of fatigue in response to an intensified training (IT) period in soccer.
