Understanding the Structure of the Muscle for Muscle Building

The human body is made of the complex system of muscles and bones. It is important to understand the components of muscles to understand the mechanics of muscle building. Muscle fibers have two main parts and these muscle fibers are furthermore, made up of many myofibrils. These myofibrils contain the necessary building muscle proteins that the muscles need for growth, the actin and myosin proteins. These actin and myosin proteins slide across each other when the muscles contract. That’s why there is a need to have sufficient protein intake so that there will be many proteins that will support the contraction of the muscles. These myofibrils are protected by a jellylike substance that provides nutrients such as oxygen, water, amino acids, glucose and creatine to each myofibril. This jelly-like substance is called sarcoplasm. There are also many baby muscle fibers called “satellite cells” waiting to be flexed to become part of the existing muscle fibers. When these baby muscle fibers become part of the muscle fibers, the body exhibits a bigger physique.
