The Composition of the Body

Muscular system of the body =============== Muscle system is a system to move the body. There are two types of muscles, spontaneous muscles and involuntary muscles, free muscles are muscles to move when you need to move, such as legs and arm muscles. If you lose consciousness, these muscles will not become active. An involuntary muscle, like a heart, is a muscle that acts even during sleep. Depending on your training, your free muscles may be cramps or slow muscles.

Muscle composition: The body contains several muscles such as bones, heart, digestion, but the basic structure is the same. In other words, muscle components are similar in that they all contain bundles, fibers, myofibrils, sarcomeres and contractile proteins. In skeletal muscle, fibrous connective tissue called outer membrane covers more than 430 skeletal muscles in the body. Inside the tendons, muscle fibers are bundled into a bundle called a bundle and usually contain 100-150 fibers. In the bundle, muscle fibers are separated by the endometrium. Beyond the branch there is an adventitia, which separates the bundle wrapped in the adventitia. Muscle fibers themselves consist of proteins called contractin proteins called actin and myosin, which are arranged vertically in the smallest constituent of muscle fibers. When contracting, the sarcocele actually becomes short and it becomes long

Body composition is the amount of fat, bone, muscle in the body. Athletes need different body components to do different sports. Football players need to have a slim body composition, as they need to be able to support the weight around the court. If the football player is obese, it makes the running for a longer time more difficult, and may make his weight more difficult. Swimmers must be slim so that they can cross the surface faster and smoother. Depending on the weight level of the boxer, the boxer should be large, heavy, or thin. So they can act fairly with their scales
