Brief Summary

Sports injuries are a very important issue for baseball players. Previous studies have found that the incidence of sports injuries faced by baseball players is continuously increasing. Sports injury rates in professional baseball, high school baseball, and college baseball players were as high as 3.6, 4.6, and 5.8 per 1,000 players, respectively. The main cause of many pitching injuries is attributed to a large number of repetitive pitches. To avoid sports injuries, it is necessary to know how to assess the risk of injury caused by repetitive pitching. Throwing is a fairly complex action that requires the coordination of the entire body. It is critical to investigate the biomechanical changes of players in order to effectively analyze such complex movements.
