Abstract

Tai Chi Chuan is one or difficult exercises to learn and teach because of its complicated forms. The objective of this study was to analyze the motion of body during the 24-form Tai Chi Chuan by three dimensions. A male expert and a female beginner participated in this study. The body motion was mensured during the tenth form "Yun-shou" of Tai Chi Chuan at sampling rate of 100 Hz by using 6 D-MotionMonitor^TM system, which was able to take 3-D position and orientation data of magnetic sensors attached to body segments and to play back the motion as computer graphic images. Differences in the body motion between the participants were unclear in the front view. In the top view, however, the peak rotation angles of "shoulders-line" (a line connecting both shoulder joints) and that of "hips-line" (a line connecting both hip joints) on the horizontal plane were clearly larger in the experts than those in the beginner ("shouldler-line" 97° v, 21 °; "hips-line" 107° v. 22°) The results indicate that the experts could make his torso rotate more widely around its long axis. Three-dimensional images made from motion capture data would help learners of Tai Chi Chuan to take notice of their unskilled motion.
