Abstract

Analysis of muscle activity by position in soft tennis forehand stroke movement. Kwon Bo Kwan Advisor : Prof. Kyung-Il Lee Ph.D. Major in Physical Education Graduate School of Education, Chosun University The purpose of this study was to analyze the EMG of soft tennis players at the front position and the players at the rear position according to the position to find out the difference. The research method is as follows. A total of 6 players were studied, including 3 players in the front position and 3 players in the rear position. Surface EMG was attached to wrist flexors, anterior triangular muscles, thoracic muscles, rectal muscles, and inner optic muscles to measure muscle activity during forehand stroke movements, and in this study, the mean and standard deviation were presented using SPSS 26.0. The results are as follows. When forehand stroke surgery was successful, the average muscle activity value was high in the order of anterior triangular muscle, wrist flexor, internal light root, great thoracic muscle, and rectal muscle, and when it failed, the average muscle activity value was high in the order of anterior triangular muscle, wrist flexor, great thoracic muscle, internal light root, and rectal muscle. Regardless of the results, the posterior position group showed higher muscle activity values than the potential position group in wrist flexion, frontal triangulation, and rectal muscles, but the average value of the potential position group was higher in the internal light root. Therefore, the development of upper and lower limb muscles is thought to have a positive effect on the performance of forehand stroke movements of soft tennis players.
