| Research Abstract |
The purpose of this study was to investigate the effect of pitching on specific tension of rotator cuff muscles in baseball pitchers.Cross-sectional area of supraspinatus muscle, shoulder abduction strength, and specific tension were measured in in 40 men (10 to 21 years). The 19-21 age group showed significantly higher specific tension of supraspinatus than that of 10-12 age group. Cross-sectional area of supraspinatus muscle,shoulder abduction strength, and specific tension were measured in 45 collegiate athletes (baseball pitchers,baseball fielders, throwing athletes, and gymnastics). It is suggested that the long-term continuation of the baseball pitching don't lead to a decrease in the quality of supraspinatus muscle.
