论“踝角”变化对速滑运动员滑跑速度的影响

Influence of the Change of "the Ankle Angle" on Skaters Speed

运用运动力学方法,从解剖学角度对滑行姿势中踝关节最小角度范围进行分析。认为较小的踝关节角度有利于提高蹬冰效果、增大滑行水平速度;并实际分析当前运动员踝角过大的成因,提出具体解决办法,为运动员及教练员重视踝角在滑行技术中的作用提供理论依据。

The article makes use of the sports mechanics to analyze the minimal range of ankle angle among the skating postures from the anatomical perspective,concluding that a smaller ankle angle is beneficial to improve the skating effect and increase the skating speed.The article also analyzes the reasons for the bigger athletes＇ ankle angle and comes up with the concrete solutions to this problem.The article provides the theory for the athletes and coaches in practice that they attach importance to the influence of the ankle angle during skating.
