| Outline of Final Research Achievements |
In this study, we compared with muscle thickness on dominant side and nondominant side in baseball pitchers. As a result, muscle thickness of the forearm（flexor digitorum profundus）, the chest（pectoralis majore,pectoralis minor）, and the back（latissimus dorsi,trapezius） were significantly greater on dominant side. On the other hand, muscle thickness of the abdomen (abdominal external oblique, abdominal internal oblique) was significantly greater on nondominant side.
In the comparison of muscle thickness between the high ball speed pitcher group and the low ball speed pitcher group, the muscle thickness of the hip extensor muscles（gluteus maximus,biceps femoris）and trunk rotation muscles(rectus abdominis,abdominal internal oblique,erector spine) were significantly greater in the high ball speed pitcher group.
