Kinematic charges such as the moving track, speed, displacement of body's center of gravity were found in the swinging leg's support in the course of the last approaching stride of Chinese elite male fosbury flop.It was proved that the supporting techniques of the swinging leg in the last approaching stride had great influence on the motion of the body's center of gravity. |
