一、短跑技术中肌肉放松的作用人的肌肉力量是有限的,肌力对某一轴肌力矩也是有限的,当肌力矩一定时,减少肌体的转动惯量可以增加转动的角速度。短跑中,从腿的后蹬结束、脚离地开始的屈膝前摆,是先屈膝关节,后屈髋关节,屈膝关节时,若充分放松伸展股直肌、股内侧肌、股外侧肌、 First, the role of muscle relaxation in sprint technology Human muscle strength is limited, the muscle strength of a certain axial muscle torque is also limited, when the muscle torque is constant, reducing the body’s moment of inertia can increase the rotational angular velocity. Sprint, from the end of the leg after the pedal, feet off the ground before the beginning of the knee flexion, knee flexion, flexion of the knee joint, flexion knee, if fully relaxed stretch rectus femoris, medial femoris, lateral femoral muscle,
