|
|
Purpose: This study is to investigate the relationship between pitcher’s ball speed, shoulder muscle strength,and proprioception.
Methods: Thirteen high school pitchers participated in this study. Ball speed was measured using a speedgun. A dynamometer and an electrogoniometer were used to measure the strength and proprioception,respectively, for both internal and external rotations in the shoulder.
Results: This study demonstrated that pitcher’s ball speed was correlated with muscle strength andproprioception of shoulder internal rotation.
Conclusion: This result will help to provide the basic knowledge for sports rehabilitation and athleticperformance.
