Study on Effects of Compression sock on Body Surface Vibration and Muscle Activity during Running

This study investigated the effects of compression socks on body surface vibration and muscle activity during running. Ten healthy male participants in their 20s with exercise experience ran on a treadmill at 12 km/h for 7.5 minutes under two conditions: wearing and not wearing compression socks. Lower leg vibration and electromyography (EMG) were measured during running and muscle hardness was measured before and after exercise. The Power Spectral Density (PSD) analysis showed that wearing compression socks significantly reduced peak PSD of vibration in the X-axis during stance and in the Y-axis during swing. The change in RMS EMG suggested that compression socks may support leg movement and enhance muscle activity efficiency in some participants. Additionally, compression socks suppressed the increase in muscle stiffness after exercise.
