유형별 스쿼트 운동 동작들이 하지근 활성도에 미치는 영향

Abstract

The purpose of this study is to investigate the effect of the stance width on lower limb muscles activity during standard squat, wide squat, parallel squat, and split squat exercise.

The subjects of this study are 20 male subjects with more than one year 's weight training experience in Busan and measured the muscle activity of the gluteus maximus, rectus femoris, vastus lateralis, and vastus medialis.

The data of this study were calculated by the mean (M) and the standard deviation (SD) using the SPSS 21.0 statistical analysis. One-way ANOVA was performed to identify differences in muscle activity of each type of squat. Bonferroni correlation was used as a post-analysis method and, statistical significance was set at p <.05. 1. In the case of gluteus maximus, among the four squat types, the activity in the parallel squat up period(P2) was the highest, followed by the split, standard, and wide squat.

2. Among the four squat types, the activity in the parallel squat down period (P1) was the highest in the rectus femoris, followed by wide, standard, and split squat.

3. Among the four squat types, the vastus lateralis was highest in the standard squat up period (P2), followed by the parallel, wide, and split order. In the down period (P1), the standard squat showed the highest value, followed by the parallel, split, and wide squat.

4. Among the four squat types, the activity of the vastus medialis muscle in the parallel squat up period (P2) was the highest, followed by the standard, wide, and split order. In the down section (P1), the highest value was seen in the split squat, followed by parallel, wide, and standard squat.

This study measured the effect of type-specific squat exercises on lower limb muscle activity, and in further studies it will be necessary to continue research on the overall measurement by synchronizing through 3D image analysis as well as comparative studies with female or control group.
