HGH – a peptide hormone of the anterior pituitary, which is used in the sport for the formation of muscle relief. Growth hormone or growth hormone (from the Latin catfish -. Body) gets its name from the fact that young people it causes a pronounced linear acceleration (long) growth, mainly due to the growth of long tubular bones of the extremities.
The base concentration (rate) of growth hormone in blood is 5.1 ng / ml, while the peaks can be increased to 10-20 or even 45 ng / ml.
· Anabolic effects – causes muscle growth
· Anti-catabolic effect – inhibits muscle breakdown
· Decreases body fat
· It regulates the use of energy
· It accelerates wound healing
· It has a rejuvenating effect
· It stimulates the re-growth of the internal organs (atrophied with age)
· Causes of bone growth and increases the growth of young people up to 26 years (up to the closing of growth zones), strengthens bones
· Increases in blood glucose levels
· Strengthens the immune system
Some effects of the drug is directly himself, but a significant part of its effects mediated by IGF-1, insulin-like growth factor (previously it was called somatomedin C), which is produced by the action of growth hormone in the liver and stimulates the growth of most of the internal organs. Virtually all of the effects of growth hormone in sports action associated with IGF-1.
Age-related changes secretion
Reduced secretion with age
The secretion of growth hormone decreases steadily with age. It is minimal in the elderly, who have a reduced level of the base, and the frequency and amplitude of peaks secretion. Baseline somatotropin is maximal in early childhood, the peak amplitude of the maximum secretion in adolescents in intensive linear growth and sexual maturation.
Daily rhythms of secretion
The secretion of somatotropin, like many other hormones that occurs periodically and has several peaks throughout the day (usually secretion peak occurs every 3-5 hours). The highest peak is observed at night, about an hour after falling asleep.
Growth hormone in bodybuilding
Initially, growth hormone preparations began to be used for medical purpose, but almost at the same time, this hormone is widely used in sports because of its ability to increase muscle mass and reduce body fat. The first products of growth hormone is a pituitary extract corpses and only in 1981 was made a drug recombinant somatotropin.
In 1989, growth hormone was banned by the Olympic Committee. Despite the fact that the use of growth hormone in athletic purposes is prohibited, in the last decade, sales of the drug have increased several times.Mainly, growth hormone used in sports, particularly in bodybuilding, where it is combined with other anabolic agents.
Increase lean muscle mass and burn fat
The main reason for the high popularity of the growth hormone in sports – the ability to reduce body fat. In addition, studies have shown that taking somatotropin leads to an increase in lean muscle mass, connective tissue and muscle cells increase in volume due to fluid accumulation.
Another beneficial effect of growth hormone – reduction in the incidence of injuries. This is due to its ability to strengthen the bone and connective (tendon, cartilage) tissue. Growth hormone accelerates healing and tissue repair after injury.
It should be noted that the use of growth hormone in pauerliftinge meaningless because it was found experimentally that it does not increase the power performance. Growth hormone also increases stamina and performance, and on the contrary a decrease in fatigue threshold and delay recovery, so growth hormone is useless for athletes of sports, where the importance of these indicators.
The general conclusion: Growth hormone can be used in sports in order to obtain relief Advantages:. High-performance, low incidence of side effects, the drug has no effect on penile function and potency, does not cause the androgenic effects and does not require the PCT, after one month of the total mass increases slightly (4.3 kg), and in some cases it does not change – this is due to the large losses of fat Weaknesses:. a high value products – about one thousand dollars per course. The drugs are expensive and actively forged, so there is a significant risk to stumble on a fake.
Side effects of growth hormone
· Tunnel syndrome
· Inhibition of thyroid function
· The accumulation of fluid
· Increased blood pressure
