The Kinematics Analysis Of Outstanding Three Level Jumpers’ The Last Step And Two Jump Of China

In the worldwide, three step jump has great influence on the track and field events, which is composed of a high intensity running and jumping combination. And it is the combination of field sports technology and complex project, which requires the player to run in high speed under the condition of three successive level jumping. It needs not only the speed, agility and good physical quality, but also a strong willpower. The Chinese men three step jump is the development advantage item in the top ten ranks. However, in the nearly10years, our man s three step jump athletics level and the world level disparity gradually expand--17.34m and18.29m. In2004, Li yanxi and Gu junjie have jumped good results---17.09meters and17.23meters. When we feel pleasure, we should still of concern at the same time.The article uses the literature material method, the expert interview method, three-dimensional imaging method and mathematical statistics method, to analysis the excellent three triple jump athletes as the research object of China at the present. This paper study from the last step of the approach and the first two skip key technology as the research content, the experiments on the different link technology analysis, understanding the key point. Through the systematic and quantitative analysis each technical link, find out that the last step of the approach and the first two jump process in some important parameters between interconnected and quantitative characteristic. Thus analysis on the three triple jump achievement influence, find out countermeasure, solve problems. Through to the Chinese elite male triple jump movement three the last step of the approach and Take-off Technique Research on characteristics, can provide three men triple jump technique in the last step and jump process in some detail data, so as to put forward some useful suggestions for technical training.
