Intermuscular Motor Unit recruitment of Lower limb according to contralateral hip motion during dynamic and isometric single leg squat

The purpose of this study is to compare the change in intermuscular motor unit recruitment of lower limb and finding better exercises.

Twenty-eight male and female adults agreed to participate in this study. Volunteers performed six motion in random sequence what used program of draw. One way repeated ANOVA was used to compare the change. A post hoc test was performed using Bonferroni correction.

There was a significant difference that was about intermuscular motor unit recruitment of lower limb between isometric and dynamic. When subjects took single leg squat (SLS) exercise during hip flexion, abduction and extension with knee flexion of non-dominant lower limb by isometric and dynamic, only one muscle, vastus medilalis was a significant difference in isometric.

The isometric SLS exercise was more effective of lower limb. Also, doing SLS exercise, extension and abduction were more effective of lower limb.
