Compression garment has been used in sports in order to improve exercise performance, such as reducing fatigue. Various studies have been conducted to elucidate the mechanism improvement of exercise performance by compression garment, and various findings have been reported. However, since the compression pressure and exercise conditions vary from study to study, there is no certain view on the effect of compression garment on exercise performance, and the mechanism has not been clearly elucidated yet. In this study, as a fundamental study to elucidate the mechanism, we focused on the phenomena that compression garment can reduce muscle activity by reducing vibration of soft tissue. Therefore, we measure and analyze changes in the vibration propagation characteristics of the gastrocnemius muscle from the body surface when the plantar flexion force and the size of the compression socks were varied. From the results, it was found that wearing compression socks reduced the vibration propagation rate of the gastrocnemius muscle in the frequency range of 10 to 30 Hz in most subjects. It was suggested that wearing compression socks greatly suppressed the vibration of the lower leg during exercise.
