摘要
对优秀短跑运动员加速跑各分段速度进行聚类分析发现，其加速过程主要有两种类型：快速平稳型加速模式和急速起伏型加速模式。对加速过程各阶段速度的相关分析表明：加速各阶段速度的增长，对加速距离、最大速度、途中跑速度、终点冲刺速度以及运动成绩，有各自不同的显著相关性。因子分析表明：加速平稳增长阶段的速度、途中跑速度、最大速度和终点冲刺速度是影响百米短跑最重要的技术因子；加速适度增长阶段的速度和加速距离是较重要的技术因子；加速快速增长阶段的速度是相对较次要的技术因子。
By using the cluster analysis on the acceleraive runnig of the elite sprinters,the author found there were two types of the accelerative running models. The relation analysis showed there were different relationships between the running velocities of the different running phases,the accelerative distance and the different phases of the acce - lerative running.The factor analysis indicated the first factor was the speed of the se - cond phase in the accelerative running, the abilities of fastest speed and the dash, the second factor was the speed of the third phase in the accelerative running and the dis - tance of the accelerative running, the third factor was the first phase of the accelera - tive running.
