摘要
建立相关的力学模型,讨论运动员在单杠旋转运动中如何增加旋转能量,杠的刚柔性对旋转运动的影响和伸展、收缩的最佳时机选择等若干问题.充分展示了力学模型对研究问题的重要意义和作用.
A physical model is constructed for an athlete on the horizontal-bar,and how to increase the energy of rotation when he is rolling on the horizontal-bar is discussed, including how the rigidity and flexibility of the bar affects the rotation and how to choose the best opportunity of the stretching and the contracting.
