优秀运动员100m短跑最大速度利用率及其特点分析

Analysis on the Maximum Velocity of Sprinting and its Characteristics in100m Running

通过对100m各分段的最大速度利用率、加速距离、最大速度、保持最大速度的距离等参数的相关和因子分析,发现前50m各分段的最大速度利用率对最大速度有显著的负面影响;而加速各分段的最大速度利用率、加速距离、最大速度和保持最大速度的距离之间的相关关系表明,人体在100m短跑全程中的能量利用具有一定的守恒性。

This paper conducted the correlation and factor analysis on the intensity of velocity, the accelerative distance, the fastest speed and the distance in fastest speed in 100 m running among elite sprinters. It is found that the maximum velocity of each 50-meter separate section has significantly negative effects on the fast speed; there exists significant correlations among the intensity of velocity, the accelerative distance, the fastest speed and the distance of fastest speed, which indicates that the human body has a certain conservation of energy during the whole course of 100 m running.
