Electrical Muscle Stimulation (EMS):Benefits & Risks
Muscle Stimulator: Muscle Stimulator also known as Electrical muscle stimulation (EMS) or neuromuscular electrical stimulation, is the elicitation of muscle contraction using electric impulses. Electrical muscle stimulation ( EMS) has received an increasing amount of attention in the last few years for following many reasons: Electrical muscle stimulation can be utilized as a strength training tool for healthy subjects and athletes.
Muscle Stimulator utilized as a testing tool for evaluating the neural and/or muscular function in vivo.
Electrical muscle stimulation used as a rehabilitation and preventive tool for partially or totally immobilized patients.
Muscle Stimulator could be used as a post-exercise recovery tool for athletes.
The impulses in the electrical stimulation machine are generated by a device and are delivered within the electrodes on the skin near to the muscles being stimulated. The electrodes are usually pads that adhere to the skin. The electrical impulses mimic the action potential that comes from the central nervous system, initiating the muscles to contract. The use of Electrical stimulation machine has been cited by sports scientists as an integral technique for sports training. An EMS machine may be effective in the initial phase of muscle strengthening. The electrical current may additionally assist pain relief, like a TENS machine, but pain relief is not it’s the chief purpose. In the United States, Electrical muscle stimulation machine or known as EMS devices are regulated by the U.S. Food and Drug Administration (FDA).

How Electrical Muscle Stimulation(EMS) help to Strengthen Muscles?
Electrical muscle stimulation (EMS) may facilitate the strengthening of weak muscles. There are several theories on how muscle stimulator may assist muscle strengthening.
One potential reason is, when you maximally contract a muscle, only a 30% of all your muscle fibers are in a state of contraction and the remaining 70% are dormant and awaiting recruitment when the contracting fibers fatigue. With Electrical Muscle Stimulation you can potentially electrically stimulate these resting muscle fibers to improve their strength. Clinically, muscle stimulator appears to be more effective when the muscles are very weak and you have difficulty performing any normal anti-gravity exercises.
Another reason that Electrical Muscle Stimulation potentially works in the speed of motor unit activation. The simple explanation is, it takes approximately 10000 repetitions for your brain to learn how to quickly send a message to your muscles via the quickest nerve pathways.
This contraction pattern of your muscle is recruited the quickest way to that muscle. Muscle stimulator can potentially provide you with repeated contractions to accelerate this learning process.
You must consult your local physiotherapist who specializes in Electrical muscle stimulation muscle retraining prior to using an EMS machine.
The FDA refuses certification of Electrical muscle stimulation devices that claim weight reduction.EMS devices cause a calorie burning that is marginal.T he calories are burnt significant amount while your body is involved in physical exercise: various muscles, heart, and the respiratory system are all engaged at once.
Luigi Galvani (1761) gave the first scientific evidence that current can stimulate the muscle. During the 19th and 20th centuries, researchers analyzed and documented the accurate electrical properties that generate muscle movement. In the 1960s, Soviet sports scientists applied Electrical Muscle Stimulation in the training of elite athletes, claiming 40% force gains. In the 1970s, these investigations were shared during conferences with the Western sports establishments. However, results were contrary, perhaps because the mechanisms in which EMS worked were poorly understood. Recent medical physiology study pinpointed the mechanisms by which electrical muscle stimulation produces the adaptation of cells of muscles, blood vessels, and nerves.
