Catabolism is a metabolic process that involves the "fall" of complex substances into simpler substances. Refers to the process of assimilation or gained respect for the conservation of energy.
Always part of large molecules, which contain large quantities of energy. These substances are processed so that remain, in the end, small molecules, poor in energy resulting from this process.
The fall of the proteins of muscle tissue for energy is an example of catabolism.
Already the anabolism (contrary to catabolism) is a metabolic process that involves the construction of molecules from others. The synthesis of proteins is an example of anabolic reaction.
When catabolism exceeds activity in the anabolism, the body loses weight, what happens in periods of fasting or illness. To avoid breaking the muscle fibers, (catabolism), the body needs a steady flow of amino acids in the bloodstream. If your body protein is not available he will get the protein you need breaking his flesh. This is the nightmare of anyone who wishes to gain muscle mass and speed up the metabolism.
To prevent the breakdown you need to eat protein in 3 hours, 3 This ensures that your body is always being filled by proteins in their diet. Also important is adequate food in protein + carbohydrate post-training and avoid starvation or train with more than two hours since last meal.
To gain muscle mass should therefore avoid the most of muscle catabolism, promoting anabolism through targeted training and adequate food.
