Purpose: The study aims at analyzing pole vaulters' pole and takeoff skills as well as providing training references for coaches and athletes. Method: Two cameras (JVC) with speed of 120 frames per second were used to film the male and female pole vault final of National Track and Field Competition in 2005. This study used Dempster's (1995) 14-segment and 21-point body model and Kwon 3D movement analytical device to do two dimensional films analyze on athletes' best performance. Results and Conclusions: 1. Grip height is related to the performance for female, that means to raise the grip height will be able to reach a better performance. 2. The takeoff angle is an inverse ratio to the grade for female pole vault. That means a smaller takeoff angle will be able to reach a better grade. 3. While taking off, if the horizontal speed and the vertical speed don't distribute appropriately, the vertical speed will become too fast and the pole bending power will decrease. Therefore, it will become very difficult to reach a proper plant position. 4. The horizontal and vertical velocity in the right and left hand that male pole-vaulter was faster than female, and left hand was greater than right hand. The slower pushing speed will cause the inferior limb too fast and influence the take-off motion. Suggestions: Enhance the holding altitude and take-off speed will be able to reach a better performance.
