踝关节伸直的力量和速度,在跑的过程中起着极为重要的作用。它与其他(軀干、两臂和两腿)关节的灵活性配合得好,就能保証运动員在最适宜的跑速中表現出必要的协調和动作自然性。发揮和保持跑速多半取决于踝关节伸屈幅度的大小,用力的程度及其动作的完整。但是,除了短跑运动員阿·依格納契夫和长跑运动員符·庫茲以外,就連我們一些較优秀的徑賽运动員也远沒有完全掌握在后蹬阶段快速而充分伸直踩关节的技术。要知道,正是由于这个看来似乎不重要的細节問題,却很大程度上决定了跑的速度。在分析跑的过程中支撑腿的工作时,我 Ankle straightening strength and speed, in the process of running plays an extremely important role. It works well with other (torso, arms and legs) joints to ensure that the athlete shows the necessary coordination and naturalness of action at the optimum pace. Play and maintain running speed depends largely on the magnitude of ankle flexion and extension, the degree of force and the integrity of its action. However, with the exception of sprinter AJ Ignatius and long-distance runner Fukutz, some of our better track athletes are far from fully equipped with the technique of quickly and fully straightening the foot during the kickback period . You know, precisely because of this seemingly unimportant detail, but to a large extent determines the speed of running. When analyzing the work of supporting legs while running, I
