A BIOMECHANICAL STUDY ON IMPROVEMENT IN THE OVERARM THROWING TECHNIQUE OF ELEMENTARY SCHOOL CHILDREN

Abstract

The purpose of this study was to investigate the improvement in technique of the overarm throwing due to a training with the standard motion model in elementary school children. Thirty-two children from the sixth grade were participated in three sessions: the pre- and post-training videotaping and throwing technique training sessions. Their throwing motions were videotaped with two high-speed cameras and analysed three-dimensionally. Through the training with the use of the standard motion model as a reference, the throwing distance and release parameters significantly improved. The throwing motion changed to be similar to the standard motion model after the training. The results indicated that the use of the standard motion model was useful for the improvement in the throwing techniques and throwing distance of less experienced children.
