In the human body the skeletal muscle tissue is the more abundant accounting for between 40 and 45% of its total weight. The body has more than 430 skeletal muscles hich are distributed in pairs on both sides. The most vigorous movements are triggered by less than 80 pairs of muscles on both sides of the body. These muscles give strength and protection to the skeleton distributing the weights and absorbing impacts: they allow the muscles to move on their joints and to maintain the body posture/stance against a force. These abilities normally represent the action of muscle groups, not of individual muscles. Using girdles for a long period of time produces a relaxation of the skeletal muscle which reduces its contraction capacity, and which causes an alteration of the muscular trophysm (the tiny myofibers that made up the muscle). The more affected muscles, because of their morphology, are the abdominal ones. EVAPAT has developed a lumbar bodysuit made with natural fabrics like SUPIMA®  cotton, X-STATIC® silver fiber and elastane LYCRA®. This garment allows you to maintain the activating capacity of the skeletal muscle system without causing atrophy.
