Strength response in human femoris muscle during 2 neuromuscular electrical stimulation programs.

Study Design: Experimental mixed repeated-measures design.

Objective: To determine the effect of 2 versus 3 neuromuscular electrical stimulation (NMES) training sessions per week on the response to strength training of the quadriceps femoris muscle.

Background: Many studies have examined the influence of training intensity (percent maximal voluntary isometric contraction [MVIC]) during NMES on the strength response of the quadriceps femoris muscle.
