Abstract: The purpose of this study was to examine the practice effect of the body sway under three conditions ; eyes closed, eyes open, and feedback condition. The feedback information was the locus of the body sway drawn on a X-Y recorder. The subjects were instructed to control their posture as well as possible by watching the pen and their loci. That was the feedback condition. The number of trials in each condition was twenty-five. The indexes were velocity, acceleration, shift length, and area of the body-sway. The results were as follows: (1) The velocity of lateral component and the area of the body sway had practice effects under the feedback condition. (2) The area of the body sways under the feedback condition was the smallest of the three conditions. (3) Females had larger area of the body sway than males. These results suggested that when the subjects controlled their posture by the feedback information used in this study, the sway of the center of gravity became more stable as the number of trials increased.
