| Research Abstract |
A high takeoff force in a short period is required in the takeoff movement of the ski jumping. It is desirable for this takeoff force not to have laterality in forming the most suitable flight posture aerodynamically. The purpose of this study was to evaluate the laterality of the takeoff force quantitatively using the biomechanical techniques. The laterality of the magnitude and timing of joint moment in lower limbs was analyzed by the motion analysis. The laterality was evaluated using symmetry index. It was recognized that laterality in the approach run posture had an influence on the laterality of the takeoff movement.
