Abstract

[Purpose] The purpose of this study was to investigate the laterality of flexibility and muscle strength in high school baseball players with shoulder or elbow injury. [Methods] Subjects were 76 high school baseball players participated in the medical check in Kyoto. Measurement outcomes were judgment of elbow and shoulder injury, range of motion, and muscle strength. Laterality of flexibility and muscle strength was calculated by subtracting non-throwing side from throwing side. Student T-test was used to analyze difference positive and negative group with each injury. The significance level was set at 5%. [Results] Laterality of shoulder internal rotation angle in positive group with shoulder injury was lower compared to negative group (p<0.05). Laterality of shoulder external rotation angle in positive group with elbow injury was lower compared to negative group (p <0.05). [Conclusion] It was suggested that the analysis of laterality in shoulder rotation angle might be helpful to predict shoulder or elbow injury in high school baseball players.
