The key point was to discuss how much pole drop techniques affected the position of the take-off point. Top six pole vaulters in 2009 ranked by Chinese Taipei Athletic Federation were selected as the subjects for the analysis. The last six strides of their run-up to take-off stride was filmed by two video cameras. Images were digitalized by motion analysis system and the kinematics parameters were obtained. The results found that the experiment revealed that the subjects’ run-up speed, length, and the changes of the frequency are unstable in the last six stride of the run-up; the last stride was the fastest, which the average speed was 4.81±0.21 stride/second, comparing with the others. However, the average speed of the run-up was the slowest, which the average was 5.70±0.36meter/second. In the last third strides, the pole carry angle was almost reaching the horizontal position. At the same time, the upper trunks of vaulters started to lean backward till the last stride, reaching the maximum trunk angle in 107.42±8.47 degree. In the moment of the take-off, all the subjects couldn’t reach the ideal take –off point. In summary, the subjects’ run-up speed were unstable in the last six strides, and during the pole drop, leaning back trunk, will affect the position of the take-off point.
