Electromyostimulation training, or EMS for short, is used in physiotherapy, high-performance sport and for medical purposes after operations. Electrical current is sent to muscle groups to intensify contraction to strengthen them. EMS training involves wearing a wired, tight and moist sports suit for 20-minute sessions.
It has gained much traction because it requires very little effort to see dramatic results. A sexy butt with little or no effort is a dream come true for most people. However, while science backs this miracle muscle sculptor, discretion and caution are to be exercised.
Without the presence of a physiotherapist or a doctor, there are risks involved. The German Society for Clinical Neurophysiology and Functional Imagery (DGKN) are not too happy about gyms offering EMS training without a doctor on board to oversee the training.
If EMS is done incorrectly it can cause rhabdomyolysis which results in kidney damage, as small muscle particles are released into the bloodstream. When muscle fibers breakdown (die) they release their contents into the bloodstream. High levels of creatine kinase (CK), an enzyme that normally supplies the muscles with energy; Myoglobin, a protein that stores oxygen in your muscles, all can cause kidney failure.
As a precaution, you must have a medical check-up done to ensure that your liver and kidney are functioning properly and you are not suffering from a muscle disorder. You must drink plenty of water after the sessions so that your kidneys can flush out the toxins. See a doctor immediately if after the EMS sessions you are in pain, have palpitations or feeling extremely weak.
