Effects of Electrical Stimulation Using the Marc ProTM Device during the Recovery Period on Calf Muscle Strength and Fatigue in Adult Fitness Participants
"The aim of this study was to determine the effects of electrical stimulation using the Marc ProTM Device (MPD) during the recovery period on calf muscle strength and fatigue in two separate studies (n = 43, Mean age = 61.3 yrs; n = 62, Mean age = 61.7 yrs). The subjects performed the calf press exercise twice a week for 10 wks with or without electrical stimulation (M = 4 hr·wk-1) between training sessions. Subjects who received electrical stimulation (n = 54) in both studies attained a significant (P<0.05) increase in calf strength versus subjects who did not receive electrical stimulation (n = 51). Only the exercise plus electrical stimulation group in both studies showed a significant (P = 0.05) reduction in feelings of calf fatigue. The results indicate that using MPD electrical stimulation during recovery enhances the effects of resistance exercise by increasing
muscle strength while decreasing the feelings of muscle fatigue."
