The Inverted Giant Swing motion is a highest technique among the various movement on the Horizontal bar. The purpose of this study lies in the factor analysis of Inverted Giant Swing motion. And so, I came to take pictures of the movements with 16 min movie camera. Subjects consisted of two highly and moderately-trained male atheletes enrolled at H University during the spring 1984. The results of this research were gained through measuring of three times a subject. The best one of three times was selected to analyse. The results were summarized as follows: 1. The removal of the center of gravity shows that sub A is slower than that of sub B, which means that V is slow by 0.14m/sec, F is larger by - 4660.05 Newton, Ek is by 2.37 Joule, Ep is by 493.08 Joule (p<0.05), U is by 270.77 Joule (p<0.001), P is by - 10.074 H.p. 2. r in case of phase I, II, shows that sub A is longer than sub B, which was resulted in an advisable movement by using of acceleration in case of phase IV. 3. Arm angle in case of point I shows that sub A is 125.0˚, sub B is 90.3˚, and is case of Trunk angle sub A is 170.0˚, sub B is 75.5˚, which shows that sub A is superior to sub B. And, It shows that subject B is lacked of the aesthetic presentation.
