A272: Imu-Based Multimodal Framework: Effects Of Mental Fatigue On Technical Movement Stability In Youth Football Players, Enyi Wang Jan 2026

A272: Imu-Based Multimodal Framework: Effects Of Mental Fatigue On Technical Movement Stability In Youth Football Players, Enyi Wang

International Journal of Physical Activity and Health

Mental fatigue has a potential negative impact on athletes' technical skill stability, yet quantitative assessment and mechanism analysis in youth football contexts remain insufficient. This study aims to establish a multimodal monitoring framework based on inertial measurement units (IMUs) to uncover dynamic variation patterns in sport-specific technical skill stability among youth football players under mental fatigue. Twenty-eight elite male youth players from professional academies (aged 15.8±1.3 years) underwent standardized cognitive loading tasks to induce mental fatigue. A distributed IMU sensing system (7-node configuration, 200Hz sampling rate) synchronously captured 17 kinematic parameters across three core technical skills (dribbling, passing, shooting), integrated …

A278: The Effects Of Mtm-Based Stepped Behavior Change Intervention On Sedentary Lifestyle Among Community-Dwelling Older Adults, Subinuer Tuerdi, Yuewei Li

International Journal of Physical Activity and Health

Sedentary lifestyles are prevalent in the life patterns of community-dwelling older adults, who have been shown to be the most sedentary and physically inactive subgroup. Prolonged low energy expenditure during waking hours leads to an increased risk of non-communicable diseases and impairs physical functioning in older adults, negatively impacting their health outcomes. Therefore, interventions targeting changes in sedentary lifestyles are necessary to improve health behaviors in older adults. An experimental study was conducted to verify whether a sedentary lifestyle modification intervention based on the Multi-Theory Mode（MTM）and the staircase approach is more effective than conventional education in reducing sedentary time and …

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.

A236: Effects Of Four-Week Blood Flow Restriction Combined With Functional Training On Physical Fitness In The Elderly, Xinge Liu, Caijiao Zang, Huawei Chen

International Journal of Physical Activity and Health

Falls resulting from age-related declines in physical function significantly affect the quality of life in older adults and increase healthcare costs. While functional training (FT) helps mitigate these declines, its impact on metabolic load is limited. Blood flow restriction (BFR) training, which enhances metabolic stress through low-intensity exercise, has emerged as a promising alternative. This study aimed to investigate whether combining BFR with FT (BFR-FT) leads to greater improvements in physical fitness in older men compared to FT alone. Thirty healthy older men (71.07±5.51 years) were randomly assigned to FT, BFR-FT, or control (CON) groups. The study included pre-test, intervention, …
