Abstract: 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.

Key words: model, gymnastics, horizontal-bar, rotation
