根据v=ω·γ关系式可知，加快角速度和加大旋转半径是提高铅球出手速度的两个因素；而旋转推球技术主要是从增大角速度而来提高速度的，同时从动量距守恒定理又可知，当运动员减小转动惯量可以提高转动角速度。在旋转推球过程中，当运动员开始旋转前上体前倾同时尽量向右转动? According to the relationship of v = ω · γ, we can see that accelerating the angular velocity and increasing the radius of rotation are two factors to improve shot-putting speed. However, the rotating ball-pushing technique mainly increases the angular velocity and increases the speed. At the same time, It is also known that when an athlete reduces the moment of inertia, the rotational angular velocity can be increased. In the process of rotating the ball, when the athlete starts to rotate, the upper body leans forward at the same time as far as possible to the right.
