Race Walking Technical Analysis Of Men’s 20km Athletes In The 26th World Race Walking Cup

Strictly limited by race walking technique definition and rules, characteristics of the status quoand development about walking technique, explore the reasonable, economic norms, walkingtechnology, practical significance. IAAF Race Walking Cup project is individual events, large-scale, high-level, is to show the world stage Elite Walkers personal strength and technique. In this paper, literature, three-dimensional imaging method, the image analysis method, mathematical statistics on the 26th IAAF World Race Walking Cup men’s 20 km race in this project Walking Technique of Elite Athletes were analyzed. Understand the current technical features 20 kilometers of Our Elite Male Race Walkers, differences and shortcomings compared with the world exist for Elite Walkers, with reference to the significance of race walking techniques to help improve and enhance our athletes. This paper studies the following conclusions:1. China’s athletes step, no significant differences cadence and foreign athletes, our traditional "small step in high frequency" technology has been significantly improved. China’s athletes single step length is 127 ±7cm, step frequency of 3.34±0.2 steps/s, single-step average speed 4.36±0.3m/s; 128 foreign athletes with disabilities single step length 3cm, cadence 3.28±0.1 steps/s, single-step average speed was 4.37 ± 0.1m/s.2. China’s athlete instant vertical leg swing leg knee angle and foreign athletes there are some differences. China’s athletes instant vertical leg swing leg knee angle average of:106±10.44±,103± 6.43±; mean of foreign athletes:115.8±5.32±,110± 6.68±. Zelin Cai instantaneous vertical leg swing leg knee angle is small, especially in the acceleration process prone to go big leg fold amplitude, high technical representation after stitch.3. Our athletes with an instant feet elevation and foreign athletes compared to the overall small, foreign players with an instant foot elevation about were:32±0.82°,34±2.94 °,our athletes with an instant foot elevation about were:30.33±4.51°,30.67±4.93 °,Zelin Cai feet elevation around the ground instantly, respectively: 26°,25°, feet elevation was significantly smaller than the other six players, easily bent knees foul penalty, more important is the impact on the knee and ankle joint force is large, easily lead to injury disease.4. China’s athletes and foreign athletes on average compared to the maximum internal rotation angle there is a gap. Walking Athletes in the largest foreign hip rotation angle left hip with an average of 27.75± 2.50°, right hip with an average of 27.5±1.73°; Walking Athletes in the country’s largest left hip hip rotation angle with an average of 26.67±4.73°, right hip average value of 25.33±4.16 °. Chen set to the maximum rotation angle of the smallest hip, left hip displacement fluctuations are relatively small, underutilized hip rotation step increase, compared with the other athletes Chen Ding-step minimum of 1.21m.
