Muscles are an important feature of the body and allow the body to move. Without muscles, I can not do anything. Therefore, it is very important for our muscle development and growth. One is to do this through exercise. Exercise has a great influence on muscle development. Exercise can strengthen your muscles through sarcomere and sarcoplasmic enlargement. Exercise is one of the important activities that helps to promote muscle development. All what we do involves the use of muscles.
Muscle muscle growth refers to an increase in muscle by increasing the amount of non-contracting muscle cell fluid (muscle). Although the muscle size is increased by training, muscle strength does not increase due to the decrease in cross sectional area, but it means a decrease in muscle fiber density. The idea is that bodybuilders do muscle growth of sarcoplasmic reticulum "not functioning". For this reason, if strong muscle concentration is required, training should be done that requires the use of a gentle representative and high load to produce myofiberal hypertrophy.

Muscle fibers are basically classified by their size and shrinkage rate. There are three main types of muscles. The first one is bone. Skeletal muscle is the largest muscle mass in the body, it is a voluntary muscle because it is a type of muscles attached to bones that can consciously control bones. Its shrinkage is short and strong, and it provides strength necessary for exercise. Muscle contraction produces and provides part of the heat required by the body
There are two main types of rapid contractile muscle fibers (ie, type II muscle fibers are classified as type IIa and type IIb), which have different fatigue resistance. This includes how muscle fibers effectively acquire the energy needed for contraction. As explained by the energy supply for muscle contraction, the direct source of (chemical) energy for muscle contraction is the molecule adenosine triphosphate (ATP) which releases energy upon degradation: ATP ADP + Pi + energy. As ATP is consumed by muscle during muscle contraction, an important aspect of muscle contraction energy supply is how muscle fibers generate ATP.
