Human Growth Hormone (HGH) does not produce stronger athletes, a recent study by Sydney-based researchers confirmed.
These scientists have discovered that drug injections enhanced sprint capacity by 4 percent plus growing breasts and other more complications.
Geoff Webster, a recreational athlete and one of the subjects for the study who was given both HGH and a testosterone, said that he noticed something wrong after taking in the hormones.
I found that my skin changed a little bit, that was just one of the physical outcomes,
I actually started to develop breasts which sort of gave me an indication that something might have been happening.
I was soaping myself up in the shower, and I thought, 'Hmm, there's something growing where it probably shouldn't be at the moment'. he said.
Dr. Ken Ho, one of the lead researchers for the study, said that positive affects of HGH can only be correlated for professional athletes.
This improvement could turn the last place finisher in the Olympic finals into a gold medal winner. Dr. Ken Ho said.
For eight weeks, 96 amateur athletes between 18 to 40 years of age were given HGH injections while half of the 63 male participants received additional testosterone.
Results revealed that HGH injections increased the sprint ability of athletes but have no effects on their strength, wellness or fitness.
And after six weeks of not receiving any injections, sprint capacity of athletes under study returned to normal.
A study published in the Annals of Internal Medicine - the journal of the American College of Physicians said that athletes who received growth hormone also complained of joint pains and swelling.
We think that the real effects of growth hormone could be far greater than what's reported in our study. Equally the side effects could be much more serious as well. Dr. Ho said.
