运用文献资料法、特征解析法和数理统计等研究方法,对世界优秀跨栏运动员跑的节奏与速度变化的时空特征进行研究。研究揭示,不同水平400m栏运动员全程跑的节奏表现出一定的差异,其中竞技水平高的运动员采用A型变换节奏的人数最多,而竞技水平稍低的运动员采用的变换节奏则由D型向G型变化;世界优秀110m栏运动员栏间跑的最大速度出现在下第6栏时,女子运动员栏间跑的最大速度则出现在下第5栏时;百米栏途中跑的栏前支撑时间与跨栏步腾空时间之比约为1:3,下栏后支撑时间与跨栏步腾空时间之比约为1:4,男女运动员栏前水平速度与栏后水平速度的变化幅度约为3.5%～5.5%。
By using the methods of literature review, feature analysis and mathematical statistics, the spatio-temporal characteristics of the rhythm and speed changes of the world’s top hurdle athletes are studied. The study revealed that the rhythm of 400m hurdle athletes at different levels shows some differences in rhythm, of which athletes with high athletic level use A-type rhythm with the largest number of players and athletes with slightly lower athletic level use D-type to G Type of change; the world’s best 110m hurdle athletes column maximum speed in the column when the next six column, the maximum speed of the female athlete column ran in the next column when the fifth column; The ratio of vacated time is about 1: 3. The ratio of post support time to hurdle time is about 1: 4. The change of horizontal speed and horizontal speed of male and female athletes is about 3.5% -5.5%.
