The aim of this study was to investigate the effects of a 12-week reha-bilitation program on body composition, shoulder pain, and isokinetic internal/external torques of pitchers with impingement syndrome. A to-tal of 30 pitchers were divided into 2 groups: experimental group (EG, n =16) and control group (CG, n=14). The rehabilitation program consist-ed of physical therapy, warm-up, work-out, and cool-down. As results, body weight and fat mass of EG were decreased whereas muscle mass of EG was significantly increased after the experiment. The pain de-grees in resting, normal daily activity, and strenuous activity on the nu-meric pain rating scale were significantly decreased in the EG. The in-ternal and external peak torques (PTs) of uninvolved and involved sides of EG were increased in EG after 12 weeks. Such results provide a defi-cit ratio of both sides in EG close to normal values. The ratios of internal/ external PTs in EG were also close to the reference values. The internal and external total works of both sides in EG were similar to the values of PT. The fatigue indices of internal and external rotators of both sides in EG were decreased. As a conclusion, a 12-week rehabilitation pro-gram reduced the shoulder pain, improved the body composition and enhanced the isokinetic shoulder internal/external rotators in EG with impingement symptoms. Also the study suggested that the rehabilita-tion program evened out the ratio between internal and external rota-tors and lowered the fatigue level after the experiment.
