Purpose : The purpose of this study was to determine changes in muscle activity due to elastic taping at the rectus femoris, biceps femoris and tibialis anterior muscles using surface electromyography analysis. Methods : In this study 10 healthy university students in the Department of Taekwondo Studies were screened and individuals with a history of previous injury or surgery to their nerve, muscle, and skeletal systems, such as paresthesia and motor disorder, were excluded. Subjects were taped over the rectus femoris, biceps femoris, and tibialis anterior and their muscle activities were analyzed using the surface electromyography method during maximal voluntary isometric contraction. Results : The results of this study were as follows: muscle activities indicated a significant increase after elastic taping than before at the rectus femoris, biceps femoris, and tibialis anterior muscle. These results lead us to the conclusion that muscle activity were influenced by elastic taping at the rectus femoris, biceps femoris, and tibialis anterior muscles. Conclusion : The results of this study show that muscle activity can be improved by elastic taping at the lower limbs. These results suggest that elastic taping of muscles in the lower extremities has the capability to increase muscle activity in the body.
