A245: Exercise Ameliorates High-Fat Diet-Induced Cardiac Dysfunction In Drosophila By Regulating Lipin Expression, Yuepeng Li, Lan Zheng
International Journal of Physical Activity and Health
High-fat diet (HFD) induces systemic lipid metabolism disorders and cardiac dysfunction, including arrhythmias, decreased cardiac contractility, and other pathological phenotypes. Exercise as a non-pharmacological intervention has potential protective effects against metabolic diseases, but its molecular mechanisms have not been fully elucidated. Lipin genes play a pivotal role in metabolic homeostasis by integrating lipid synthesis, catabolism, and energy-sensing signals. In this study, we used Drosophila as a model to investigate whether exercise ameliorates HFD-induced cardiac dysfunction in Drosophila by regulating the expression of Lipin, a key gene for lipid metabolism. Method: Wild-type female Drosophila (n=360) within 12 hours of pinning were …

A252: Effects Of Heavy Resisted Sprint Training On Acceleration And Kinematics: A Systematic Review And Meta-Analysis, Lilin Jia, Biyu Zhang, Miaoyu Han, Guojie Wang
International Journal of Physical Activity and Health
Acceleration is a key determinant of performance in athletics and team sports (e.g., football, rugby). Resisted sprint training has gained significant attention as a method to enhance acceleration, typically through the addition of external resistance, such as sleds or resistance devices. Recent focus has been on heavy resisted sprint training (HRS), defined by resisted loads ≥30% body mass (BM) or ≥30% velocity decrement (Vdec). However, the long-term effects of HRS compared with non-resisted sprint training (NRS) on acceleration performance and kinematic adaptations remain inconclusive. This review with meta-analysis aims to review the current literature on intervention studies investigating the effects …

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 …
