This study investigated pitching motion reproducibility in baseball using two pitchers as subjects, a graduate student and a person on the university ball team. Both were asked to actually throw, and a photograph was taken with a high-speed camera. Analysis was done using 2-dimensional picture. The results revealed that the coefficient of variation of the arm motion [two subjects] increased among the seven items measures. From this, it is thought that the arm motion before release (forearm, upper arm, and elbow) is related to ball control.
