The Biomechanical Analysis on Takeoff Technique between Chinese Female Jumper and World Elite Jumper in High Jump

By using the method of biomechanical research, the author analyzes the takeoff technique of Chinese female jumper and world elite jumper in high jump. The result show that the height of body center of gravity of our jumper is lower than world elite jumper, there is significant difference,but there is no significant difference in takeoff speed. Chinese Female jumpers have a faster takeoff speed and a shorter takeoff time than world elite jumper. During the phase of takeoff, the range of buffer of hip and knee for our jumper is larger, but the ankle's buffer is smaller. In addition, our jumpers have some shortcoming in bar skill.
