The alteration in the range of motion (ROM) of the shoulder joint is one of the risk factors for shoulder injuries in athletes who play overhead sports. The purpose of the present study was to compare the ROM of the shoulder joint between athletes who play overhead sports andthose who do not. A total of 181 male college athletes without shoulder injuries were divided into two groups: subjects playing overhead sports (OHS, n = 105) and non-overhead sports(n-OHS, n = 76). The shoulder joint ROM parameters of internal rotation, external rotation, horizontal flexion, and horizontal extension were measured. The total arch of shoulder rotation was calculated using the internal and external rotation ROM. The internal rotation ROM in the OHS group was smaller than in the n-OHS group. The external rotation ROM in the OHS group was greater than the n-OHS group. There were no significant differences in horizontal flexion ROM, horizontal extension ROM, or total arch between the dominant side and nondominant side in both groups.
