“The purpose of this study was to compare the gluteus maximus and hamstring group electromyographic (EMG) activation levels among selected weight-bearing resistance exercises. Eighteen young adult females with previous resistance training experience completed the study.”
.
“Strength was assessed on the bilateral squat (3 repetition maximum), modified single-leg squat (3 repetition maximum), and stiff-leg deadlift (8 repetition maximum) to determine an 8 repetition maximum load for all lifts.”
.
“During EMG data collection, 3 repetitions were completed using an 8RM load on all 3 exercises.”
.
Gluteus maximus EMG was significantly greater than hamstring group EMG on the bilateral squat (40.3 vs. 24.4%), modified single-leg squat (65.6 vs. 40.1 %), and stiff-leg deadlift (40.5 vs. 29.9 %).”
.
“The modified single-leg squat gluteus maximus EMG was also significantly greater than the stiff-leg deadlift and bilateral squat, whereas no difference was found between the stiff-leg deadlift and bilateral squat. Comparing the activation of the 2 muscle groups in all exercises, the gluteus maximus seems to be the primary muscle recruited whereas the modified single-leg squat seems to produce greater gluteus maximus and hamstring group activation. The data indicate that it would be most beneficial to include the modified single-leg squat during Gluteus maximus and hamstring group training.”
