The purpose of this study was to investigate the relationship between the ball velocity and upper extremity kinematics in inexperienced individuals during a 5 weeks selfpractice overarm throwing. Seven women participated in this study. Participants performed 15 overarm throwing 3 days in a week for 5 weeks. The relationship between the ball velocity and the first-last week overarm throwing upper extremity kinematics data (maximum angles and angular velocities) were statistically analyzed using Spearman’s rho. Results showed there was weak to moderate relationship for both maximum angles and angular velocities of trunk, shoulder, and elbow. Rotational movements of upper extremities should be prioritized at the early stages of throwing skills acquisitions
