KINEMATIC ANALYSIS OF THE RUN UP FINAL STRIDE AND TAKE-OFF TECHNIQUE IN CHINESE FEMALE FOSBURY FLOP JUMPERS

Abstract

The flop high-jump technique consists of a run up, take-off, flight and landing. Among these four phases, the take-off is the key to performance. The path that a jumper's center of gravity (CG) follows during flight is determined by the height of center of gravity before take-off, velocity that the athlete is propelled upward at take-off, and take-off angle. The run up will influence take-off technique and body movement in flight. Therefore, the final stride of the run up is the transitional phases connecting the run up and take-off. The purpose of this study was analyzed and estimated the final stride of the run up and kinematics of take-off technique used by Chinese female jumpers.
