| 摘 要： | 运用三维录像解析法、数理统计法、对比分析法等方法对我国优秀女子20km竞走选手后半程竞走技术进行研究，以田径理论和生物力学知识为基础，对所得数据与世界优秀选手对比分析。结果得出：我国选手在身体重心上下位移、蹬伸角度及肩髋扭转角等参数方面，与世界优秀水平相比，均存在显著性差异。蹬伸用力效果差是造成这种技术表现的致因所在。

| Abstract: | Based on the theory knowledge of Track and Field and sport biomechanics, by using the research methods such as three axis vidicon film analysis data analysis and so on. the paper studied the technology of national excellent women＇s 20 km Race Walking athletes in the latter match. The result shows that the parameters of the torsional angel of shoulder and coax, body bary center, extending angle and the others of national athletes are obviously different from the international because of bad extending |
