依据高速摄影及国际田联竞走规则，对第５届全国大学生运动会男子２０公里 竞走比赛的运动员进行技术分析，结论如下：１．摆动腿摆动时间长于支撑腿支撑时 间。２．摆动腿方向和线路应低平，增加髋绕人体垂直轴的扭转幅度。３．应控制摆动 腿的膝角的最小角度。４．为了减少摆动时间应提高髋和踝的水平速度，５．减少后蹬 角提高重心水平移动速度，提高单步效率。 Based on the high-speed photography and IAAF race rules, the technical analysis of the athletes in the 20-km race of men in the 5th National University Games was carried out. The conclusions are as follows: 1. Swing leg swing time longer than the support leg support time. 2. Swing leg direction and the line should be low level, increase the torsion of the hip around the vertical axis of the human body. 3. The minimum angle of the knee angle of the swinging leg should be controlled. 4. In order to reduce swing time should increase the horizontal velocity of the hip and ankle, 5. Reduce the pedal angle to improve the horizontal movement of the center of gravity to improve single-step efficiency.
