In recent years, compression garments have been used in sports to improve athletic performance, such as reducing fatigue and extending exercise time. There is no certain view on the effect of compression garments on exercise performance, and the mechanism has not been elucidated yet. Therefore, to elucidate the mechanism of the effect of compression garments on the improvement of athletic performance, in this study, we focused on the relationship between soft tissue vibration and muscle activity. Specifically, the study was aimed at clarifying the effects of compression garments on body surface vibration and muscle activity characteristics during walking, in which impact is applied to the heel. Frequency analysis of the vibrations measured on the lower leg from heel ground contact to heel release was performed. As a result, it was confirmed that the power spectrogram density (PSD) value of the medial head of the gastrocnemius muscle in the circumferential direction of the lower leg became lower when the subject wore compression socks. It was suggested that wearing compression socks greatly suppressed the vibration of the lower leg during exercise.
