Background and objective: This study aimed to assess the relationship between range of motion (ROM) and isometric strength of the shoulder joint, adjusted for humeral head retroversion angle (HHRA), in professional baseball pitchers.
Material and Methods: A total of 18 pitchers from a professional
baseball team were included in this study. The isometric strength of internal
rotation (IR) and external rotation (ER) were measured using an isokinetic device
Results: The HHRA of the dominant arm was approximately 7
Conclusions: Thus, the increase of IR ROM in professional baseball
pitchers was associated with an increase in isometric strength at 25
