The purpose of this study was to analyze factors that affect elementary school high jump results using 3D motion analysis. The conclusions of this study suggest three areas where coaches can improve the performance of elementary school athletes: approach, take-off, and bar-clearance. The angle of approach should be a smooth curve and athletes should be taught to lean inside the track as they approach their jump. Further they should be taught to walk with gradually longer strides while maintaining horizontal velocity. The athlete’s impact time at approach should be longer. The athlete’s motion of take-off should become stronger as the bar gets higher. To make efficient use of gravity athletes should put their head and toes down at the point of bar-clearance.
