“An EMS stimulus fires all the motor neurons in the treated area simultaneously, creating an uncoordinated contraction, which is primarily isometric in nature. Voluntary muscular contractions, on the other hand, roll through the muscle in a wave to generate a coordinated, directed force.
EMS works directly on the muscles, bypassing the body’s energy conservation system, thus there’s no limit to the percentage of fiber that can be activated. The EMS stimulus “spills over” from fully contracted fiber to activate remaining fiber (given sufficient current) allowing the athlete to experience a training stimulus that’s unattainable by any other means. ”
