This study sought to determine the effects of transcutaneous electromyostimulation (EMS) combined with dynamic contractions employed during weight lifting exercise. Male weight-trained college athletes (N = 24) were randomly assigned to 1 of 4 groups; weight training only (Wgt), EMS only (Stim), weight training + EMS (Wgt + Stim), or control. All groups were pre- and posttested to determine one-repetition maximum (1-RM). The Wgt and Wgt + Stim groups trained 3 times a week at 85% of 1-RM, 3 sets of 8 to 10 reps; Stim received EMS 3 times a week. The strength of all 4 groups was tested biweekly and adjustments were made so that Wgt and Wgt + Stim continued to train at 85% of 1-RM. Two-way ANOVA found no significant difference between groups when the study began. Results showed that the Wgt + Stim group differed significantly from the other 3 groups. The Wgt and Stim groups were equal but differed significantly from control. All 3 experimental protocols led to significant increases in strength, but combining EMS with dynamic contractions may be the most effective.
