运用生物力学方法对短道速滑与速度滑冰项目的弯道滑行中一系列定量数据通过物理公式计算与时相分析。找出优秀短道速滑运动员同项群换项速度滑冰项目后在弯道滑行中的优势。研究认为:同速度滑跑时短道速滑弯道滑行运动员所受惯量支撑力大于速度滑冰,是使短道速滑运动员达到一定竞技水平并换项速度滑冰后,在速度耐力方面优势较为明显的主要原因。通过对被试运动员蹬冰角度与髋、膝关节时相分析;有效滑速测试范围内的短道速滑运动员弯道滑行中,开始蹬冰角度均小于速度滑冰;更有利于侧向分力的产生,对加速度起更多贡献。右腿蹬冰时间曲线也表明;短道速滑运动员右支撑腿蹬冰时间的延长是运动员需要改变更大的身体“角位移”角度,运动员所需平衡能力与身体的控制能力要求更高。以上研究希望对具备一定竞技水平的短道速滑运动员转项速度滑冰后在弯道滑行技术上所产生优势附上科学的依据。
A series of quantitative data of curve gliding in short track speed skating and speed skating using biomechanics method are calculated by physical formula and phase analysis. Find out the advantages of elite short track skaters in curve gliding after changing the same skating speed skating team. The research shows that: when the speed skating curve short track skating curve skaters suffered inertia support greater than speed skating, short track skater is to achieve a certain level of competition and change speed skating, speed stamina more obvious advantages The main reason. By analyzing the angle of the ice and the knee joint of the tested athletes, the short-track skaters in the range of the effective skating test are less inclined than the speed skating in the curve skating, and are more conducive to the lateral component The emergence of more contribution to the acceleration. Curve curve of right leg pedal ice also indicates that the extension of the right leg support ice skating time of the short track skaters is that the athlete needs to change the angle of the larger body and the required balance ability of the athlete and the control ability of the body more high. The above study hopes to attach a scientific basis to the competitive advantage of short-track skaters with a certain competitive level after skating transitional speed.
