A few days ago listening to your body changed its image. He has appeared a new category, in motion, with the intention of introducing both theoretical and practical guides, of exercises and stretches. Who do you think you will be the star? Obviously it will be who generates this movement, the muscle. Let me present it, because from now on, I know that you are progressing in the habit of healthy life, you’ll have to be friends. Know him, to work with him, learn to listen when you try to talk to you, explain your feelings, and know how to ask you answer when you want something on it or need it. What is a muscle can understand to skeletal muscle (which belongs to the locomotor), as an independent structure with a basic (but not unique) function, generate movement between two bones, by means of one or more joints.

Thus, the muscle is presented as a flexible body, such as a rubber band, that is born in a bone (source) and anchor in another (inclusion), exceeding the point of union between both bones, joint during his tour. It is in the joint where really will take place the movement. The essential feature of the muscle is its capacity for contraction and relaxation. If collapses, muscle traccionara from its source to its insertion, shortening its length, increasing its volume and approaching their ends. If you relax, it shall not exercise any tension between origin and insertion and these will tend to move away; the muscle stretches and loses weight. Along its route, the muscle will be divided into two basic parts: tendon and muscle belly. The tendon is the part that is anchored to the bone, being a sort of woven hybrid, half bone its hardness and consistency, medium muscle flexibility and contractile potential. It is the white part of the muscle, having low blood circulation and lots of nerve endings in your interior.
