Abstract

Analysis of muscle activity during soft tennis backhand stroke movement Jeong Tae Hyeon Advisor : Prof. Kyung-Il Lee Ph.D. Major in Physical Education Graduate School of Education, Chosun University The purpose of this study is to examine the analysis of differences in muscle activity according to the results of backhand stroke movements of soft tennis elite male players. The research method is as follows. Six elite university athletes were selected as the subjects of the study. Surface EMG was attached to wrist extensors, humerus triceps, posterior triceps, vertebral standing muscles, and inner light roots to measure muscle activity during backhand stroke operations, and in this study, the mean and standard deviation were presented using SPSS 24.0. The results are as follows. When the backhand stroke operation was successful, the muscle activity of the mean and standard deviation was high in the order of wrist extensor, rear triangular muscle, upper arm triceps, spinal standing muscle, and inner optic muscle, and when it failed, the muscle activity of the mean and standard deviation was high in the order of rear triangular muscle, wrist extensor, upper arm triceps, spinal standing muscle, and inner optic muscle. Therefore, applying a program that increases the stability and accuracy of the operation of the game by identifying the muscle activity according to the results when performing the backhand stroke will positively affect the backhand stroke movement of the soft tennis player.
