Understanding The Coach Learning Environment In Formal, Field-Based Settings: A Self-Determination Theory Perspective, Jody L. Langdon, Shayla Snow

Journal of Coach Development

Grounded in self-determination theory (SDT), the purpose of this study was two-fold: 1) to evaluate the psychometric properties of SDT-related measures in a sample of coach learners, and 2) to examine the relationships between need satisfaction and frustration, coach motivation, and engagement in training sessions.. A total of 796 coaches participated in the study, completing surveys measuring basic psychological need satisfaction and frustration, coaching motivation, and engagement. Aside from confirming the validity and reliability of measures for use among coach learners, findings indicate that satisfaction of basic psychological needs positively correlated with intrinsic motivation and engagement, while frustration of these …

Social Support And Mental Toughness As Predictors Of Perceived Stress Among College Kinesiology Students, Jianmin Guan, Wan Xiang Yao, Xiaofen D. Hamilton, Gaofeng Lu

International Journal of Physical Activity and Health

Drawing on Lazarus and Folkman’s transactional theory of stress and coping, this study examined the associations of age, gender, three types of social support (family, friends, and significant others), and mental toughness with two dimensions of perceived stress (helplessness and coping inefficacy) among 666 college students majoring in Kinesiology. Hierarchical multiple regression analysis revealed that male college students, as well as those with higher levels of mental toughness and family support, reported significantly lower levels of helplessness and coping inefficacy in managing stress. Additionally, greater support from friends was significantly associated with lower levels of coping inefficacy, while younger students …

Gender Differences In College Students’ Physical Activity Self-Efficacy, Social Comparison Beliefs, And External Frames Of Reference, Ken Murfay, Sarah Pyszczynski, Sarah Collins

International Journal of Physical Activity and Health

This study examined whom college-aged individuals believe observing would more likely increase their physical activity self-efficacy (PASE) for a physical skill, whom they are more likely to compare their abilities to within a physical education (PE) class, how often they compare themselves to others in PE, and what students’ PASE scores were. Based on the mean scores for each question, students were more likely to compare themselves to a student than a teacher, friend than a non-friend, and similar or higher skilled peer than a lower skilled peer. To increase students’ confidence for a physical skill, students had higher levels …

A196: Prediction Of Cardiovascular Function Improvement Based On Wearable Device Motion Monitoring And Otnmanba-Bilstm Model, Yixuan Li, Lan Zheng

International Journal of Physical Activity and Health

Cardiovascular diseases are among the leading chronic health conditions worldwide, with prolonged physical inactivity or improper exercise increasing the risk of their occurrence. Existing studies suggest that well-structured exercise interventions can significantly enhance cardiac function and improve the adaptability of the cardiovascular system. However, accurately predicting the long-term impact of different exercise durations and intensities on heart health remains challenging due to individual physiological differences, exercise habits, and lifestyle factors. This study employs a data-driven approach to develop a predictive model based on wearable device motion monitoring data, aiming to elucidate the dynamic relationship between exercise and cardiovascular health and …


A197: Perceptual Behavior And Social Interaction Of Chinese College Students Toward Esports, Xianhua Luo Jan 2026

A197: Perceptual Behavior And Social Interaction Of Chinese College Students Toward Esports, Xianhua Luo

International Journal of Physical Activity and Health

Social exchange theory (SET) has been extensively used to recognize students’ perceptual behavior (PB) and social interaction (SI). Research has examined the potential factors of recognition and socialization against the economic factors in individual evaluation, seeking rewards or avoiding costs in relationships. The positive impact of PB and SI is a significant experimental approach to studying social psychology. Therefore, the processes of individuals’ perceptual behavior and their social interactions in Esports might address this research gap. Hence, the purposes of this study were to explain the PBs and SIs toward Esports among college students in China. Method: 341college students were …

A214: Effects Of Tai Chi And Brisk Walking On Sensation In Pn Elders, Qiongqiu Zhao, Qipeng Song

International Journal of Physical Activity and Health

Peripheral neuropathy (PN) is a prevalent neurological disorder, affecting 26–39.2% of adults aged 65 and older due to peripheral nerve degeneration and associated conditions like diabetes. PN leads to sensory impairments, including diminished tactile sensation, increased fall risk, and mobility issues. Tai Chi (TC) is a low-impact exercise shown to enhance sensory function and balance in healthy older adults, but its effects on PN patients remain unclear. Brisk walking (BW) is a widely recommended exercise for older adults, yet its impact on sensory function in PN is not well-established. This study compares TC and BW interventions on tactile sensation in …

A090: Development And Efficacy Evaluation Of Virtual Reality (Vr)-Based Personalized Exercise Prescriptions For Perimenopausal Women, Runze Zhu, Zekai Wu

International Journal of Physical Activity and Health

Perimenopausal women (aged 45–54) frequently experience climacteric symptoms such as vasomotor disturbances, osteoporosis, and cardiovascular risks due to declining ovarian function and estrogen levels. Approximately 75% of women report varying degrees of discomfort, with 80% exhibiting at least one symptom (e.g., sleep disorders, mood fluctuations). Conventional exercise prescriptions often lack specificity to address individual health disparities and comorbidities (e.g., osteoporosis, metabolic dysfunction). This study aimed to develop a virtual reality (VR)-based personalized exercise prescription system to enhance exercise adherence through immersive experiences and evaluate its efficacy in alleviating perimenopausal physiological and psychological symptoms. A personalized exercise prescription generation system was …

A116: Resistance Training Vs. Moderate-Intensity Continuous Training On Cognitive Function In Nafld Patients, Yineng Tan, Xueying He, Jianyu Gan, Dapeng Bao

International Journal of Physical Activity and Health

Non-Alcoholic Fatty Liver Disease (NAFLD) is the most common chronic liver disease globally, with a prevalence of nearly 30%. It is closely related to cognitive dysfunction, which significantly impacts quality of life. Recent studies suggest that exercise therapy (aerobic/resistance training) can improve metabolic abnormalities in NAFLD, yet its effects on cognitive function remain controversial. Moderate-Intensity Continuous Training (MICT) may have advantages over Resistance Training (RT) in modulating lipid metabolism, though RT might be more feasible for specific groups. This study compares the effects of 6 weeks of MICT and RT on cognitive functions (verbal memory, visuospatial ability, executive function, and …
