研究表明人体60%的力量是通过踝关节表现出来的,踝关节是推动人体运动的重要关节,踝关节的灵活性对人体协调运功起着非常重要的作用,直接影响运动成绩的好坏。短跑运动要求运动员要具备较强的力量和速度,这就对运动员的踝关节的灵活性要求更高。在选拔短跑运动员时力求跟腱长且细,因为这样运动员的踝关节灵活性更强。所以在训练中更应该注重踝关节的灵活性和力量练习。一、加强灵活性练习方法(一)脚踝绕环练习:一脚支撑,另一脚脚尖点地按顺时针和逆时针方向旋转。(二)脚拨球练习:一脚支撑,另一脚用脚前掌 Studies have shown that 60% of the body’s strength is shown through the ankle joint, ankle joint is an important joint to promote human movement. The flexibility of the ankle joint plays a very important role in coordinating the human body and directly affects the performance of the athletic performance. Sprint requires athletes to have a strong strength and speed, which requires more flexibility for the athlete’s ankle. A short and careful Achilles tendon is selected in the selection of sprinters, because this athlete’s ankle flexibility. Therefore, training should focus more on ankle flexibility and strength exercises. First, to strengthen the flexibility practice methods (A) practice ankle loop: a foot support, the other foot tip clockwise and counterclockwise rotation. (B) foot ball practice: one foot support, the other foot with the forefoot
