This study was attempted to explan the characteristics of starting motion between experts and non-experts swimmers by help of 3D video comparison of their kinematic factors related to body segmentsat the point of starting. Thus, this attempt aims to provide scientifically fundamental data to swimmers and their trainers with a guidance by which they can teach how to start more precisely and efficiently at track starting point. To fulfill this objective, this study conducted an experiment with 5 expert high school swimmers and 5 non-expertl high school swimmers to compare and analyze duration time for motion by phase, COM position, COM velocity, angle of each joint at starting motion. And it brought forth the following result.. First, the experts showed a faster reaction velocity and shorter time necessary for motion than the non-experts at the track starting motion. Second, the non-experts showed a grater displacement to the right and left of COM than the experts at the track starting motion. Third, the experts showed faster COM velocity than the non-experts at the point when the both hands were detached from a starting block. Fourth, when the finger tips touched on water surface in diving, the experts had greater joint angle of shoul-ders, elbows, hips and knees than the non-experts. Fifth, the experts showed farther distance in diving than non-experts.
