International Journal of Physical Activity and Health
The development of motor coordination between the ages of 3 and 6 is a critical time for children. Good motor coordination not only serves as the foundation for children's daily activities but also promotes the maturation of neural development, thereby facilitating the growth of their language, intelligence, and emotional abilities. Developmental coordination disorder (DCD) is a disease characterized by significantly impaired motor coordination. Children at risk for DCD (rDCD) often have emotional and behavioral problems that can negatively affect long-term outcomes. The purpose of this study was to compare the differences in emotional-behavioral problems between children with rDCD and typically …

A263: Exploring Cadd-Based Binding Modes Of Androstenedione And Its Metabolites With Potential In Vivo Targets, Yuhong Ding, Wei Dong
International Journal of Physical Activity and Health
The abuse of androstenedione, an endogenous steroid hormone, among athletes to enhance performance is a significant concern in sports. Current anti-doping detection methods are limited by short detection windows and high false-positive rates, largely due to the transient nature of primary metabolites. To address these challenges, this study employs computer-aided drug design (CADD) to identify stable, long-acting metabolites of androstenedione that can extend the detection window and improve anti-doping efficacy. The integration of CADD with sports physiology principles allows for a more comprehensive understanding of how exercise-induced metabolic fluctuations can influence the detection of these metabolites. Method: Molecular docking simulations …

International Journal of Physical Activity and Health
Generative Artificial Intelligence (GAI) has the potential to enhance both the efficiency and outcomes of course learning for sports major students. However, no existing research has specifically examined the factors that may influence these students' use of GAI in their course learning. The Theory of Planned Behavior (TPB) proposes that attitude (AT), subjective norms (SN), and perceived behavioral control (PBC) are key determinants of behavioral intention. Additionally, perceived ease of use (PEU) and expectation confirmation have been identified as factors that may be associated with intention. Therefore, this study aimed to test an extended TPB model to explore sports major …

A253: Examining Health Variations Between Resistance Training With/Without Breathing Retraining In Overweight Young Women, Huan Cai, Chengye Dai
International Journal of Physical Activity and Health
Physical inactivity and overweight are public health concerns among young Chinese women. A decrease in respiratory strength and endurance has been reported in obese/overweight individuals, as the increased fat accumulation in the chest wall and trunk leads to weakness of the respiratory muscle and changes in breathing patterns, resulting in decreased lung ventilation, the capacity for oxygen delivery, and utilization. Studies showed that RT can increase cardiopulmonary function as shown by improvement of submaximal exercise and increased peak oxygen uptake (VO2peak), resulting enhancement of muscle hypertrophy. Breathing retraining (BR) can also manipulate breathing patterns. Therefore, the purpose of this study …

A280: Physical Activity, Social Support, And Stress Among High School Students, Moderating Effects Of Only-Child Status, Yining Hu
International Journal of Physical Activity and Health
Stress levels reflect an individual's psycho-physiological imbalance in response to environmental demands. Research suggests that physical activity not only directly alleviates negative emotions but may also indirectly reduce stress levels by enhancing social support networks. However, the underlying mechanisms of this pathway and the moderating effects of family structure differences (e.g., only-child status) are unclear. This study aimed to explore the relationship between physical activity and stress levels among high school students in Shandong Province, test the mediating role of social support between the two, and analyze the moderating effect of only-child status on the relationship. Method: The present study …
