So far, this research adopted three gymnasts as a scope, utilized ground reaction force instruments, and analyzed factors of changes in performing the motion from the angle of a motor mechanics. The results of analysis are as follows. Greatest is the time required to make a turn of circle motion between entry and front in the locomotive section. This is because the left hand touches the ground reaction force instrument and keeps the balance of the centroid. Values of Fx, Fy, and Fz from ground reaction force instruments suggest that the circle motion encounters a difficulty in taking the balance due to the small surface of the front and the reduction of the frictional force and that it takes the balance to turn the right hand and the left hand outward and the strong sustainment of the right hand enables a gymnast to perform naturally the next motion. This research suggests that analyses of electromyogram and kinematic analysis are to be made in order to draw more meaning conclusion. This research leaves this as a future study.
