摘要
400 m跑最佳的速度分配模式是取得优异成绩的重要因素。短跑的速度是由运动员的步频与步幅这2个最重要的因素决定的。400 m跑时,步幅和步频这2个决定跑速的主要因素,实际上是处于一个不断组合,不断变化的动态过程中。这种不断组合和变化的步态对400 m跑的速度结构有着非常重要的影响。作者通过研究世界高水平400 m运动员的各分段速度、步频、步幅等运动学参数并对数据进行统计学分析寻找出在各分段速度下步频与步幅变化规律及其对速度结构的影响。从而为运动训练实践提供理论依据。
The best speed structure is a key factor to the excellent result of 400m dash,while two decisive factors affecting the speed are stride frequency and stride length,which form a continuous changing combination influencing the speed structure significantly during the full course.By researching the full changing patterns of stride length and stride frequency and their influence on speed structure, we can get theoretical basis for the athlete＇s training.With mathematical statistics analysis to the sports parameters and date produced by sixteen athletes in the finals of the sixth and seventh World Track and Field Championship Contest,we can find the changing patterns of stride length and stride frequency and their influence on speed structure within each speed stage.Adopting relative and factor analysis,the thesis elaborates the growth at each stage in the full course speed structure of 400m dash,and stride length and stride frequency as the two main factors influencing the speed structure.
