Kinematic Research on Crura Klap Technique of Chinese Excellent Male Speed Skaters in 500-m Race

By the methods of standard three-dimensional measurement and videotaping analysis, with male skaters who attended the Tenth National Winter Sports as objects of research, the fast running technique in 500m race with kinetic research is analysed. The purpose suggests the kinetic regularity in the course of fast running, in order to enrich technique theory of speed skating and supply the reference data for teaching, training and scientific research. The findings indicate: firstly, for our country excellent male speed skaters, the distance of preparing posture strong point is small, the former stability angle is small and partial ahead, technological movement is relatively reasonable, thus creating the beneficial advantage for finishing pedal and ice state from static state to fast starting. Secondly, for our country excellent male speed skaters, the angle of pedaling ice and the inclination angle of upper part of the body are relatively close during the course of starting; the result of pedaling ice is better. Thirdly, for our country excellent male speed skaters, the distance of step frequency is not remarkable; the size of stride exerts a great influence on the speed during the fasting stage.
