Muscle Mass is defined as the volume of the total body tissues that correspond to muscle. Looking at it from the perspective of body composition, muscle mass corresponds to lean mass, the other two elements that compose it being body fat and water. It is important to point out that there are three types of muscle, firstly, the heart muscle is located, which is part of the heart, then smooth muscle is located, this can be located in the visceraand finally the skeletal muscle, the latter being colloquially known as muscle itself, its function is to allow the body to carry out different movements and maintain different positions. Muscle mass has the ability to expand or bulge depending on the force that the subject applies. If you apply great force to the muscle, the greater the mass that will emerge to resist.
Many living beings including humans, such as animals, carry out various physical activities with which the muscle mass tones the body. The way in which animals develop their muscle mass is through the intestine and also helped with the instinct of survival. That is, if they have the need to eat, they will do whatever is necessary to get food, regardless of the physical effort that it requires, on the other hand, in the case of human beings so that they can maintain their muscle mass in tone. With body fat, it is necessary for them to carry out various scheduled physical activities, some examples are routines in the gym, regular walks, exercises of various types and sports in general.
In humans , the body has 3 different types of muscle groups. The largest being the skeletal muscle, which is distributed throughout all areas of the body, since it is attached to the body covering the bone structure. Then the cardiac muscle is positioned, this forms the heart, the main organ of the circulatory system, this type of musculature is hollow and is located in the thoracic cavity through which blood is pumped. Finally, there are the smooth muscles that are the composition of the rest of the organs such as the viscera.
