테니스 플랫 서브 후 스플릿 스텝 동작의 근활성도 비교분석

Abstract

The purpose of this study was to compare and analyze the muscle activity of the split-step motion after a tennis flat serve. This study obtained the following results. First, in phase 1 of the skilled and unskilled, the average muscle activity was significant in the left and right spinal erect muscles, left rectus femoris, right medial large muscles, left and right lateral vastus muscles, right biceps femoris, left and right tibialis anterior muscles, and right gastrocnemius It appeared to show a difference. And the maximum muscle activity of Phase 1 was found to be significantly different in the right vertebral erection muscle, medial vastus muscle, lateral vastus muscle, and biceps femoris. Second, the average muscle activity in phase 2 of the skilled and the unskilled showed a significant difference in the left and right medial latissimus, biceps femoris, gastrocnemius, and right lateral vastus. And the maximum muscle activity of phase2 was found to be significantly different in the left rectus femoris, right medial latissimus, lateral latissimus dorsi, and gastrocnemius. Third, the average muscle activity in phase 3 of the skilled and the unskilled showed a significant difference in the left and right rectus femoris, the right medial vastus, lateral vastus, tibialis anterior, and gastrocnemius. And the maximum muscle activity of phase3 showed significant differences in the right rectus femoris, medial latissimus, biceps femoris, and gastrocnemius. Fourth, the average muscle activity in phase 4 of the skilled and the unskilled showed a significant difference in the left rectus femoris, medial latissimus, tibialis anterior, and gastrocnemius. In addition, the maximum muscle activity of phase 4 showed a significant difference in the left rectus femoris and tibialis anterior muscles.
