Humans generally experience much difficulty in making the same motions repeatedly. When a person can repeat a series of motions in the right way, we think he or she is well able to reproduce such motions. The purpose of this study was to investigate the possibly significant correlations between the reproducibility of movements in basketball and the results of free throw shooting performance, and between the reproducibility of the physical joint motions and the results of the shooting performance. The subjects in this study were ten male college basketball players. The movement of the balls and angles of the elbow, knee and shoulder joints were measured. From these data, the coefficient of variations were calculated. The results of this study were as follows : (1) In the motion of the ball after its release, the coefficient of variation was lowest for the height of the central part of the ball. The resultant velocity and angle of projection steadily decreased. (2) In the latter half of the motions in free throws, the coefficient of variation in elbow joint angles inclined lower. (3) In terms of the free throw success rate, the coefficient of variation in knee angular velocity in both groups revealed a characteristic difference.
