Let's now make a brief review of the fundamental notions for understanding the topic.
of a tissue or organ by increasing them, but not their number.Nevertheless, following the application of a specific motor protocol for the increase of muscle mass, in the past some studies highlighted a "sort of cell proliferation". It was then discovered that, in reality, this consisted in the specialization of the so-called satellite cells, or silent units capable of evolving - following the right stimulus - in the type of necessary unit.
It is only through specific training - which involves high intensity muscle work (HIT) and strength (with a high eccentric component), therefore against resistance (resistance training), more frequently constituted by the use of overloads - supported by a contribution adequate nutritional, which can be achieved a considerable increase in muscle mass.
Muscle hypertrophy is the result of a cascade of events, which has been defined as upstream signaling, which causes downstream effects. This cascade of events includes in sequence:
- Mechanical and metabolic stresses that lead to structural damage (micro-trauma), an increase in the production of lactic acid and depletion of energy reserves, especially for phosphates and only partially for glycogen;
- Mechanical stress reports on muscle fibers;
- Hormonal (testosterone, GH, MGF, IGF-1, cortisol) and inflammatory response;
- Protein synthesis and increase in contractile fibers, and increase in the enzymatic pool, cell organelles and specific energy substrates, and therefore also in cytosol.
- Allowing all bodily movements that require this property;
- Participate in pulmonary ventilation, more precisely in forced expiration;
- By constituting the core, to contribute to the stabilization of the trunk.
It seems logical that, in all healthy organisms, the rectum of the abdomen should be physiologically capable of carrying out these tasks, but if we wanted to evaluate this ability, the discussion would change.
