This study sought out to test the effectiveness of using electrical muscle stimulation (EMS) on increasing strength and endurance of the gluteus muscles compared to volitional exercise. Seventy-two female volunteers between the ages of 20 and 60 years old were assigned to either an EMS (n=24), volitional exercise (n=24), or control group (n=24). The EMS group underwent stimulation 5 days per week for 30 minutes each day at the highest tolerable level for 6 weeks. The volitional exercise group completed 3 sets of 10 quadruped hip extensions on each leg, 5 times per week, for 6 weeks. Subjects were tested at the beginning, mid-point, and end of the study. Isometric strength of the gluteal muscles was tested using a Chatillon CSD 200 Dynamometer; endurance was measured using a hip bridge movement. The stimulation group had a 15% increase in gluteal strength compared to only a 9% increase of gluteal strength in the volitional exercise group. Gluteal endurance increased by 29% in the stimulation group compared to 26% in the volitional exercise group. The findings of this study show that there were no significant differences in gluteal strength or endurance between groups.
