| Summary: | The sway of the center of gravity and that of the various parts of human body were measured by use of Gravicorder and TV-Tracker about a healthy male. To find out crosscorrelation and phase deff erence of f regencies, the both sways were analyzed with a spectral analysis. Results on the subject are as follows; 1) It was found that there was component of the f regency of approximate 0, 2 Hz in each sway. 2) The components of the both sways had positive cross-correlations each other, and they had phase differences at several points of the body. 3) In the both Ant.-Post. directional sways, power of this freqency had a tendency of decrease when it was tested with eyes closed. |
