以第六届世界田径锦标赛女子 2 0 0米决赛的 8名运动员为对象 ,分析了起跑与起跑后的加速跑和途中跑阶段的速度特征、冲刺跑技术的运动学特征 ,以及 2 0 0米跑前后两个 1 0 0米时间等 ,表明 0～ 50米速度比较重要 ,50～ 1 0 0米段速度和 2 0 0米跑成绩相关关系显著 ,1 0 0～ 1 50米段时间和 2 0 0米跑成绩相关关系不显著 ,但该阶段对途中跑技术影响很大 Taking the 8 athletes in the 260th woman track in the 6th World Athletics Championships as the target, this paper analyzes the speed characteristics of the accelerating and midway running phases after starting and starting, the kinematic characteristics of the sprint running technique, Two hundred and ten meters before and after the run time and so on, indicating that 0 to 50 meters speed is more important, 50 ~ 100 meters section speed and 200 meters ran performance significant correlation between 100 and 150 meters time and 2 The correlation between 0 0 m run score is not significant, but this stage has a great impact on the run technology
