The purpose of this study was to deduce a systematic method of teaching of the move in the forward roll and the forward roll with stretched knees of the move in the floor exercise, and which was examined the movement form (morphologic form of the move) to compare the experienced subjects with the un-experienced subjects. As the result, the followings were found : 1. The experienced subjects showed some effective motions to improve the move on both events. The most important motion in the move was holding-up the feet as high as possible at the beginning which gave him an advantage to use the higher potential energy, and at the latter half of the move shortening the radius of gyration and flapping the upper body. 2. The un-experienced subjects did not show these motions noticeablly in their moves of both events. So that, their moves seemed to be done only depending on the inertia at the beginning of them. 3. Each subject showed the personal, highly significant similarity of their movement forms between both events. These finding aforesaid are proposing that it must be necessary to be made a teaching which concerning on the effective motion to improve the efficiency of gyration, even in an stage of teaching about the most fundamental move, the forward roll.
