A065: Effect Of Mental Fatigue On Lower Limb Biomechanics And Acl Injury Risk In Basketball Players, Zeyang Zhang, Bosong Zheng, Youping Sun Jan 2026

A065: Effect Of Mental Fatigue On Lower Limb Biomechanics And Acl Injury Risk In Basketball Players, Zeyang Zhang, Bosong Zheng, Youping Sun

International Journal of Physical Activity and Health

Anterior cruciate ligament (ACL) injuries are prevalent among basketball players, particularly during abrupt stop-jump actions. While most existing studies have focused on the impact of physical fatigue on athletic performance, the role of mental fatigue has been largely overlooked. High-intensity games can induce mental fatigue, which may further increase the risk of ACL injuries by altering lower limb biomechanical characteristics. However, the underlying mechanisms remain unclear. This study aimed to investigate the effects of mental fatigue on the biomechanical characteristics of the lower limb during a sharp stop-jump task in basketball players and to assess whether mental fatigue increases potential …

International Journal of Physical Activity and Health

Alzheimer's disease (AD) is a neurodegenerative disease characterized by cognitive impairment, with evidence suggesting that exercise can improve cognitive function. Our previous studies demonstrated that aerobic exercise improves cognitive dysfunction and enhances synaptic plasticity in APP/PS1 mice, while identifying the endogenous microRNA-3473e as a potential regulator of neuronal activity and cognitive function. However, the precise mechanism underlying this regulation remains unclear. This study aimed to investigate the mechanism by which aerobic exercise regulates miR3473e to improve synaptic plasticity and cognitive dysfunction in APP/PS1 mice. Exercise intervention was performed on 3-month-old C57BL/6J and APP/PS1 mice with a 12-week moderate-intensity aerobic treadmill …

A074: Vr / Ar Technology Innovation In Sports Training: From Action Capture To Multimodal Feedback, Chenhan Xu, Zekai Wu Jan 2026

A074: Vr / Ar Technology Innovation In Sports Training: From Action Capture To Multimodal Feedback, Chenhan Xu, Zekai Wu

International Journal of Physical Activity and Health

Traditional sports training is constrained by limited environmental controllability, delayed feedback, and insufficient motion quantification. VR/AR technologies offer immersive interactions and multimodal feedback systems, enabling high-fidelity scenarios, real-time motion capture, and precise quantitative analysis for motor skill development. This study systematically examines technological innovations in motion capture and multimodal feedback within VR/AR frameworks and evaluates their efficacy. The research integrate motion capture technologies (e.g., Kinect V2 skeletal tracking with deep learning algorithms) and multimodal feedback systems into a three-stage framework: 1) A hybrid inertial-visual motion capture system achieving joint angle modeling with an error margin < 1.5°; 2) Multimodal feedback design incorporating visual overlays (motion trajectory projection), tactile vibrations (HaptX glove force feedback), and spatial audio cues; 3) Real-time biomechanical analysis modules assessing cognitive-motor coordination via synchronized eye-tracking and electromyography. Experimental trials involved soccer/tennis athletes and rehabilitation patients in comparative training studies. 1) VR-trained soccer athletes exhibited 23% faster tactical decision-making and 18% higher action anticipation accuracy than the control group; 2) Tactile-visual multimodal feedback improved tennis serve standardization by 31%, outperforming single-modality interventions; 3) AR-integrated gait rehabilitation increased patients' POMA balance scores by 42%, with 92% training adherence. However, neck fatigue caused by device weight reduced long-term compliance for 15% of users. VR/AR technologies enable quantifiable, personalized, and context-adaptive sports training through high-precision motion capture and multimodal feedback. Their core value lies in transcending physical space limitations and accelerating neuro-muscular memory formation. Future research should prioritize lightweight device design and 5G-edge computing-enabled distributed training systems. While multimodal synergy is validated, feedback modality prioritization requires task-specific optimization—e.g., spatial auditory cues for team sports versus tactile precision enhancement for fine motor tasks.

A075: Endurance Exercise Downregulates Sparc To Improve Age-Related Myocardial Fibrosis In High-Fat Flies, Wenqing Huang, Lan Zheng

International Journal of Physical Activity and Health

Myocardial fibrosis is an important pathological feature of cardiovascular aging, and a high-fat diet (HFD) can accelerate its progression, while SPARC, a remodeling-related protein, may mediate this mechanism. Endurance exercise has been shown to have cardioprotective effects, but its regulatory mechanism on age-related myocardial fibrosis induced by a high-fat diet is still unclear. This study aims to explore whether endurance exercise improves the cardiac fibrosis phenotype in high-fat-fed fruit flies by downregulating SPARC expression and elucidates its underlying molecular mechanisms. Method: Wild-type female fruit flies (n=400) within 12 hours of feathering were selected and randomly divided into four groups (n=100 …
