In theory, yes. The nervous system itself runs on electrical currents sent from the brain to the muscles. In theory, an amplified current to a particular muscle setting could make you stronger, faster, etc. But it's also extremely risky. You're body will not be use to such physical strain, and you could possibly end up with a pulled/ripped muscle, or worse. Paralysis. I only recommend attempting this trick under a last resort only situation.
