In previous studies, baseball pitching motion has been divided into the following six phases: (1) windup phase, (2) stride phase, (3) arm cocking phase, (4) arm acceleration phase, (5) arm deceleration phase, and (6) follow-through phase. Based on the findings of previous studies, this report summarizes the coordinated movements of various parts of the body and the related muscle activity in the above six phases. In addition, we focused on two sections of these six phases (between arm cocking and acceleration phases, and between arm deceleration and follow-through phases), and systematically reviewed how to prevent injuries, related to the pitching motion.
