Abstract: The purpose of this study was to examine the amplitude and the types of the sway of the center of gravity under three conditions; eyes closed, eyes open, and feedback conditions. The feedback information was the locus of the body-sway drawn by 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 results were as follows: (1) Fifty subjects had the smallest amplitude under the feedback. (2) Males had larger amplitude than females under three conditions. (3) Males and females had the same ratio of amplitude of feedback to eyes closed, of eyes open to eyes closed, and of feedback to eyes open conditions. (4) The centripetal type was the most frequent under the feedback condition. Furthermore, males and females had almost the same tendency. These results suggested that the sway of the center of gravity became more stable when the subjects controlled their posture by the detailed feedback information.
