초록

The purpose of this study was to investigate the difference on Quadriceps femorisactivity performed wall squats during various dynamic tasks.
Thirty one subjects, with no history of patellofemoral pain(PFOP), quadriceps injury, or other knee injury participated for this study. Muscle activation of the vastus medialis obliquus, rectus femoralis, vastus lateralis muscles were recorded while subjects performed 10 consecutive wall squats. Subjects performed the wall squats during four different four methods: (1) general wall squat, (2) back against fitness ball (3) weight in hands, (4) add in arms movement.
Statistical analysis were accomplished by utilizing the one-way ANOVA(Bonferroni's post hoc test) by SPSS 20.0 program. Significance level was set at p<.05. Muscle activations induced under the four different motions were compared and results showed that there was significant difference only in vastus medialis obliquus and rectus femoralis but there was no significant difference in vastus lateralis. The vastus medialis obliquus was significantly different back only against fitness ball at post-hoc test. The rectus femoris was significantly different back against fitness ball & add in arms movement at post-hoc test.
Based on these results, we conclude that muscle activations are influenced by performing wall squats using various dynamic tasks in healthy adults
