Most men, especially in youth, looking for muscle development as a way of exalting their vanity and also as a matter of self-assertion and many are in the practice of bodybuilding and muscle growth is a response to your desire.
But the question is always the same how this “forced” muscular development occurs, longer than before that nothing there is a natural biological development, usually governed by food and genetic characteristics of each individual.
When someone tries to start a gym in training load, be prepared to face long hours of sacrifice where progress will be imperceptible, but steadily, the results begin to appear. This muscle growth, from the physiological point of view is a muscular development that occurs in response to two simultaneous processes, muscle hypertrophy and hyperplasia.
The first is the increased size of muscle fibers, and second is the increasing number of these same fibers. These two processes occur simultaneously, where the hypertrophy response in turn to increased size of the sarcomere (contractile part of muscle fibers) and enlarged sarcoplasmic (the non-contractile muscle fibers).
There are also several theories, how would a cellular level that muscle growth, for example, it would be a permanent destruction and rebuilding of muscle fibers, whereas every 30 days renewing the entire muscle.
Another theory is that the muscle is subjected to great stress, when training with weights and this would cause a large release of hormones, which are responsible of the process of muscle hypertrophy. Still others argue that the right is the theory of hypoxia, which produce a strong reduction of blood oxygen, causing protein synthesis by increasing amino acids.
Also, there are those who claim that the only muscle development due to a greater amount of blood flow as naturally occurring nutrient in muscle mass and that this increased demand for food, would result in hypertrophy.
What is known for certain is that muscle growth does not occur during training, but between 24 to 72 hours, when the muscle is at rest. Anyway, it is important that each practitioner knows, that there are other partners for a better outcome such as feeding and rest.
The first that provides the energy necessary for the development and the second because it is the time frame in which the body eliminates all the toxins produced by the combustion itself metabolism.
