Title: DEVELOPMENT OF THE OVERARM THROWING MOTION FOR JAPANESE ELEMENTARY SCHOOL GIRLS
Abstract: The purpose of this study were to investigate characteristics of the overarm throwing motion for Japanese school girls, 2nd, 4th and 6th grades, with a standard motion model of skilled girls. The throwing motions of fifty-one girls were videotaped and seven girls for each grade were selected based on the throwing distance for 3-D motion analysis. Throwing distance, ball velocity and release height were significantly increased with the increase in school grades. The 2nd grade girls threw by a dominant shoulder joint
abduction and elbow joint extension, the 4th grade girls indicated a large range of motion of the right upper limb, and the 6th grade girls strode forward with the trunk leaned to the right and used a rapid external-internal rotation of the shoulder joint.
