Why do you grow your muscles

The increase in muscle mass is the result of adaptation. The body is not a monolith, fixed once and for all, but remains in a dynamic state. This means that each day loses a certain number of elements and renews these elements rebuilds. 

In childhood and in youth, reconstruction prevails over decay – thanks to this we grow and mature. In the adulthood, the body rebuilds exactly as much as lost, and later we lose more than we rebuild.

Thus, the state of the measure is a state of dynamic equilibrium, unless … we force the organism to adapt. If we increase the loss of body elements, eg through effort, the body will start to compensate for it (build up). It is a defense mechanism of the system. Excessive loss of body elements is a deep imbalance in life – a shock for the whole body. 

Thus, the body accumulates elements in excess, in reserve, in order to reduce the balance of subsequent losses if necessary and that the next shock should not be as drastic as the previous one. This is the essence of adaptation. 

Excessive loss of body elements (muscles) can be caused by training. When we take into account dry tissue (without water), more than 90 percent of muscle mass is a protein. It’s easy to guess that the elements lost and built up within muscle tissue will be proteins. 

 

How are they growing …? 

It is clearly visible that in order for mass to grow, effort or training is required. Without it, I am not talking about the development of muscles! 

While the muscles contract – they work, the tissue loses several times more protein than at rest. This is the basic impulse for overcompensation of proteins, and thus for the development of musculature. 

Depending on how many and what proteins the muscle cell loses, there are three basic directions of overcompensation (or only compensation) of losses. The above phenomena are determined by the nature of physical exertion. 

The methodology of training plays the most important role here. Bodybuilders should only be interested in (or mainly) such training, the consequence of which will be to compensate for contractile proteins, because they primarily determine the mass and strength of muscles. For the sake of order, however, it is worth to talk about all three muscle repair mechanisms. 

Exchange of cell organelles 

We observe this reparative mechanism in endurance (aerobic) efforts and it is the most attractive for representatives of endurance disciplines. In bodybuilding, he gains weight while working on the definition of muscles, that is when we want to burn body fat.

As a result of oxygen-related efforts, damage and losses of mitochondrial proteins – organelles responsible for the energy recovery of cells – occur. The body reproduces and multiplies the mitochondria. As a result, cell energy is improved, energy substrates are better used, aerobic capacity increases from training to training. The increase in the number of mitochondria results in increased fat burning. His subcutaneous supplies are quickly disappearing, however, mitochondrial proteins make up a small part of the overall mass of musculature. Endurance training does not lead to an ‘explosion of dimensions’.

Cell exchange 

Moving on this subject, the ‘specialist’ often mistreats the poor ‘pakers’ in their heads. If the muscles are subjected to irrational, very hard and destructive training, there is such a significant loss of protein components that the cell can no longer compensate or even repair it. Such a cell dies and is replaced by a new cell. The destroyed cell replaces the cell maturing as a result of the reductive division of the stem cell.

Because stem cells belong to the germ cell population and are immortal, hence the irresponsible demagogues concluded that by destroying muscles with a frantic workout, you can achieve incredible muscle mass progression. This is completely wrong reasoning!

The number of cells in the body is precisely controlled and it can not be multiplied. It is about the existential form of a given species. That is why the elephant is an elephant and man is a human being. If these mechanisms were out of control, we would have people the size of elephants and vice versa. 

As a result of the reduction of the stem cell, only as many cells as can be destroyed can be reproduced. But not always. More often than they can be reproduced completely. Why?

Pseudo professionals forget that whenever muscle cells are destroyed, they are replaced by new muscle cells originating from satellite (parent) cells or by connective tissue cells – fibroblasts. Fibroblasts produce a protein – collagen, which performs the task of organic dressing, When fibroblasts make the damage occurring, so-called adhesions. I know a lot of bodybuilders who ‘dealt’ in this way. Muscles overgrown with connective tissue contract, become dense, compact and small, resemble a pile of tennis balls – a guy looks like a knotted string. Such a silhouette will never achieve the desired expression. So beware of the demagogues’ fire and paranoid hard training!

Replacement of protein components 

Methodically well-conducted strength training will cause significant loss of muscle proteins without destroying whole cells. In this situation, the muscles will be forced to overcome the losses. The player will be able to enjoy the increase in weight and strength.

You’re probably interested in what’s happening in muscle cells now? Well, the complex of phenomena occurring in them is extremely complex. No one else has managed to completely trace it and fully explain it. Generally, during the training and for a few days after its end, two metabolic phenomena of catabolism and anabolism, in other words, the breakdown of proteins and their re-formation occur in the muscles. Catabolism serves to ‘dismantle’ dysfunctional and ‘spoiled’ protein components. Thanks to anabolism, these elements are rebuilt and superstructed (overcompensated) again. So there is no anabolism without catabolism!

Key and lock 

The whole of biochemical phenomena in the living organism explains the receptor theory. Well, to control the course of life processes, the body uses substances called effectors, acting as a key – and substances acting like a castle, called receptors. The appropriate keys open the appropriate locks. The ‘door’ of biochemical reactions opens and closes. The same phenomena control the processes associated with the increase of muscle mass and strength. So if in the muscles catabolic and anabolic phenomena proceed in parallel, the body simultaneously operates with packages of opposing sets of ‘keys’ and ‘locks’.

 

Regardless of the nature of the phenomenon, the role of effectors – keys is played by energy quanta, radicals, hormones, vitamins, vitamins and minerals. The role of receptors – castles – biological membranes, protein components of biological membranes, transport proteins, genetic material structures and enzymes. 

Catabolism 

The strongest catabolic stimulus is neuronal stimulation during efforts. Neurons treat the muscle cell with an electric current, as a result of which the muscle fibers (movement act) shrink and the fiber proteins are damaged. Also enzymatic proteins involved in the act of movement are damaged. Damaged protein components are further degraded with the participation of radicals and catabolic hormones (cortisol, histamine, serotonin, prostaglandins). The work ends with cellular enzymes that break down proteins into amino acids or even simpler carbon compounds. The amino acids produced as a result of catabolism are not lost, but can be used to produce energy or to synthesize a new protein.
