Official title
Motion and Electromyographic Analysis of the Forehand Topspin Against Topspin, Forehand Topspin Against Backspin, Forehand Stroke, and Forehand Attack in Elite Table Tennis Players
Overview
This research will analyze and compare the muscle activation levels, muscle recruitment timing, trunk kinematics, and shoulder joint kinematics between the four forehand strokes and between elite table tennis players with and without shoulder injuries, providing insights for daily training and rehabilitation programs to reduce the occurrence of sports injuries.
Detailed description
The study participants will be elite table tennis players aged between 13 and 40. Participants must have competed in the Chinese Taipei Table Tennis Ranking Tournament or the National Table Tennis Championships within the past three years and have at least four years of table tennis experience, and train for more than 10 hours per week.
The study involves four types of forehand strokes: forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack.
Interventions
- Device motion capture system, surface electromyography
forehand topspin against topspin, forehand topspin against backspin, forehand stroke, and forehand attack
Primary outcome measures
