Abstract: The rotation about the second axis is unstable in the free rotation of the rigid body with three inequitable axes, and then the body does a complex rotation, though the rotation about the first or the third axis is stable. The motion of the 'moon-sault' of gymnast can be approximately considered as rotation of the rigid body, and the player has used chaotic phenomena with three inequitable axes of the human body to control his posture. Also the player has matched the rotation to the timing of landing by increasing or decreasing the rotational energy just a little by the hands and feet's little bending or stretching.
