Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, is the elicitation of muscle contraction using electric impulses.
EMS has received increasing attention in the last few years, because it has the potential to serve as: a strength training tool for healthy subjects and athletes; a rehabilitation and preventive tool for partially- or totally immobilized patients a testing tool for evaluating the neural and/or muscular function in vivo; a post-exercise recovery tool for athletes.
The impulses are generated by a device and delivered through electrodes on the skin in direct proximity to the muscles to be stimulated. The impulses mimic the action potential coming from the central nervous system, causing the muscles to contract. The electrodes are generally pads that adhere to the skin.
Body builders and weight loss gurus are seeing this technique becoming more and more popular among many of their clients. Using electrical muscle stimulation with a regular exercise program doubles the results that you would normally have with exercise alone. Your muscles are getting an extra workout without actually having to put in more time at the gym.
Combining exercise with the stimulation is the quickest way to reach your desired goal, although you do not have to have an extensive exercise routine to see results. Muscle stimulation is a great alternative to using chemicals to enhance and boost muscle tone.
The electrical muscle stimulation device can only be used by professional physicians. Any kind of novice's intervention can be dangerous, if you haven't consulted with a doctor.
