The main impact on the body of anabolic steroids work is due to the so-called cell-receptor theory. In simplified form, it looks as follows. skeletal muscle cells, sebaceous glands, hair follicles, some endocrine glands are unique receptors. When injected into the human body a steroid molecule with the blood spread throughout the body. Cell receptor molecule captures steroid: a compound of the receptor – steroid. This bunch enters the cell nucleus, and the result of certain biochemical reactions start protein synthesis begins. Enhancement of protein synthesis provides an increase in the number of protein molecules, and thus achieved the volume growth and strength of skeletal muscles. This increase was observed only when the corresponding physical stimulation of the muscles.
Perhaps steroids provide strengthening formation and accumulation of large amounts of creatine phosphate. Creatine phosphate, in turn, contributes to the accumulation in the muscle cell of some enzymes, including adenosine triphosphate (ATP). It is known that ATP is the energy source for the reduction of skeletal muscle.
After contact steroids muscle cell accumulation occurs enhanced nitrogen muscle cell. This is a sure sign that there is a synthesis of muscle fibers, which is an accumulation of glycogen in the body as anabolic steroids work increase the production of its own insulin. The accumulation of glycogen in turn helps to increase muscle size and endurance.
Increased muscle mass and volume under the influence of steroids is associated with an increase in blood volume in the body, with the increase in its flow to the muscles, and therefore with a better supply of oxygen (due to the large number of red blood cells), as well as increasing their efficiency.
Growth of body weight can be explained by anabolic-channel offset tabolicheskih processes occurring in the body in favor of the former. As you know, in our body are constantly occur two processes: anabolic, ie renovation of old and new cells and catabolic – cell death… During catabolic processes responsible hormone cortisol produced by the adrenal glands. It is possible that the steroids may reduce the amount of the catabolic hormone or cell receptor blocking catabolic.
