The growth hormone It is well known in the world of the Sport as a powerful anabolic, as it has great power for increase muscle mass of the organism.
Sometimes the increase is associated in the lean mass, composed mainly of muscle, with the increase in the physical performance. However, a review of scientific research shows otherwise.
After making a meta-analysis which reviewed 44 articles of 27 different studies that evaluated people aged between 13 and 45 years, the researchers concluded that growth hormone, while increasing muscle mass, does not improve the exercise capacity.
Taking human growth hormone produced a significant increase in average 2kg of lean mass, which includes not only muscles but also water.
At the same time it was observed a small increase in fat mass (almost 1 kg) and there were no improvements in the endurance. On the contrary, researchers found signs of a deterioration in the performance of athletes and an increase in capacity was not found for lifting.
The factor associated with possible damage growth hormone of the athletic performance they are elevated levels of lactate that it showed in some of the items included in the analysis. Even within the review, we found data that speak of unwanted side effects after administration of hormone.
Many of us committed can this hormone not only as a stimulant of muscle mass, but apparently the scientific evidence shows otherwise.
It is important to know more about beliefs popular in the world of sport, that ruined important sports racing can be seen if our beliefs are wrong. Therefore, I think necessary to carry out more research and reviews on the matter that will expand our knowledge on the subject.
