The effect of compressional under-layer on muscle activity and exercise performance using EMG

The effect of functional under-layer on muscle activity and exercise performance was investigated on the basis of physiological tests and electromyography (EMG). EMG was used to study muscle activity during exercise after fitting compressional under-layer. We observed slight differences in the results of anaerobic and aerobic muscle EMG tests among subjects because of differences in body muscle content. In addition, muscle activity was varied according to muscle parts used during the physiological tests with fitting the functional under-layer. We suggest that compressional under-layer decreases muscle vibration and improves blood circulation, resulting in overall improved muscle activity on the basis of the usage of different muscles in each type of exercise. However, future studies are needed to evaluate the long-term effects of the functional under-layer.
