Recently, compression wear has been attracting attention for the purpose of improving physical functions during exercise. Various studies have been conducted to clarify the mechanism of improving fatigue reduction by compression wear. However, there is no common, definitive finding across many studies, since compression pressure and exercise conditions differ among studies. In this study, in order to elucidate the mechanism of the fatigue-reducing effect of compression wear, we focused on the hypothesis that compression wear can suppress muscle activity by reducing the vibration of soft tissues. We measure and analyze changes in the vibration propagation characteristics of the gastrocnemius muscle during calf raise exercise due to wearing compression socks. From the results, it was confirmed that wearing compression socks have influence on vibration intensity on body surface, muscle activity, muscle hardness and fatigue feeling. In the subjects whose feel reduction of fatigue, it was confirmed that muscle activity and vibration intensity were reduced by wearing the compression socks. It was suggested that the reduction of vibration on body surface contributed to the reduction of muscle fatigue by compression socks.
