Androgenic anabolic steroids are derivatives of the male sex hormone testosterone. As the name of this class of doping drugs implies, the main effects of anabolic steroids are aimed at “building” tissue and muscle building.
Sexual, or steroidal, hormones (androgens, estrogen and progesterone) are synthesized in the gonads, or gonads, – the male testes and female ovaries. Sex hormone production obeys the so-called mechanism “feedback”. The essence of this mechanism should be clear to the athlete, as this explains some of the side effects of exogenous anabolic steroids.
The launch of steroid hormone production begins with the release of tropic hormones from the pituitary gland, as we discussed above. Getting into the various glands with blood, they stimulate the secretion of hormones.
The reader realizes that for each endocrine gland there are its own triggering tropic hormones. For the gonads, these are gonadotropins – follicle -stimulating and luteinizing hormones. Returning to the mechanism “feedback”, it should be explained that with an increase in the level of tropic hormones in the gonads, the production of steroids increases and, accordingly, with an increase in the level of the latter, the release of gonadotropins is inhibited.
Anabolic steroids have a significant impact on the growth of athlete’s strength indicators due to an increase in muscle volume and strength. However, these effects are manifested only in combination with physical exercise and a sufficient influx of building material for muscles in the form of protein and amino acids.
Androgens belong to the group of steroid hormones, which include sex hormones, in particular testosterone. Synthetic analogs of androgens are called anabolic steroids. However, glucocorticoids also belong to the steroid group, which have a slightly different and even opposite effect – catabolic, and not anabolic.
Scientists argue about the mechanism of action of steroids on the muscles. In particular, it is known that many synthetic anabolics are able to block glucocorticoid receptors and thus inhibit catabolic processes.
Testosterone, called the male sex hormone, is also produced in small amounts in women. This hormone has two main properties.
The androgenic and anabolic effects of testosterone are used by athletes to achieve muscle growth and strength. With the androgenic effect, the development of male sexual characteristics is associated.
However, synthetic anabolic steroids, created far from sports, have a slightly different effect. Pharmacologists have created synthetic anabolics with some “skew” towards anabolic action. The androgenic effect of drugs is reduced.
The effects of anabolic steroids include the ability to accelerate tissue healing, which is associated with activation of protein synthesis, stimulation of muscle growth, the addition of strength and strength endurance in the gain, stimulation of the synthesis of creatine phosphate and the accumulation of glycogen in muscles.
