Objectives
Narrative objectives1
The purpose of this study is to investigate the relationship between lower extremity and trunk motion and shoulder/elbow injury risk parameters during baseball pitching. In addition, this study aims to examine the effects of different lead-leg landing conditions on upper extremity joint loading and trunk/pelvic motion during pitching, and to explore their potential applications for injury prevention and rehabilitation.

Primary outcomes
Peak elbow valgus moment during pitching under each landing condition
Key secondary outcomes
Ball velocity, shoulder joint moments, pelvic and trunk rotational angular velocity, and lower extremity kinematics/kinetics under each pitching condition will be measured during the experimental session.

Interventions/Control_1
Participants will perform maximal effort baseball pitching toward a target net. Pitching conditions will be modified by changing stride foot landing position and foot contact pattern at lead foot contact. Ten successful trials will be collected for each condition. Motion capture systems, force plates, high-speed cameras, electromyography, and IMU sensors will be used for biomechanical measurements. Total participation time will be approximately 2 to 3 hours.
