The aim of this study was to clarify the changes in muscle coordination during butterfly swimming at different swimming speeds. Eight female swimmers performed 25 m butterfly at 60%, 80% and 100% effort. Two-dimensional motion analysis was ...
The effect of holding a costume on jump-landing performance and biomechanics in Lion Dance [0.03%]
武术醒狮舞服对跳跃落地表现和生物力学的影响
Wanyan Su,Thanh Nguyen,Yu Gu et al.
Wanyan Su et al.
Lion Dance is a traditional Chinese performance art that requires dancers to execute numerous jump-landings while holding a costume, which restricts upper-body movement. The current study aimed to quantify the effects of holding a costume o...
Task-specific plantar pressure adaptations in individuals with patellofemoral pain syndrome during dynamic activities: a systematic review [0.03%]
膝前痛综合征患者在动态活动中足底压力的特异性适应变化：系统性综述
Megan Gordon,Eddie Austin,Li-Shan Chou et al.
Megan Gordon et al.
Altered plantar pressure distribution may be associated with patellofemoral pain syndrome (PFP), particularly during dynamic activities; however, findings on task-specific adaptations remain inconsistent. A systematic search was conducted i...

This study aimed to characterise early flight posture and classify movement strategies in ski jumping of trunk, hip, and knee kinematics. Using a 10-camera markerless motion capture system, three-dimensional motion data were collected from ...
Advancing the concept of technical ability of force application in sprint acceleration [0.03%]
助力跑加速的技术用力概念的构建与完善
Marvin Zedler,Jan-Peter Goldmann,Tobias Alt et al.
Marvin Zedler et al.
Technical ability of force application (sagittal force vector orientation) is considered a performance determinant in sprint acceleration, yet the underlying kinematics require further investigation. Sixteen elite male bobsleigh athletes pe...
Kinematic determinants of the Tomoa skip starting in elite male speed climbing athletes [0.03%]
