South African athlete Alexander Mokone has been kicked out of the All Africa Games in Nigeria after he tested positive for the banned substance, nandrolone.
Nandrolone is listed as a “Anabolic androgenic steroid” under “Prohibited Classes of Substances” by the International Olympic Committee (IOC) in their Olympic Movement Anti-doping Code (OMAC).
Nandrolone belongs in the same class of banned substances as stanozolol, DHEA, testorone and other anabolic steroids. Nandrolone is also commercially known as Deca-Durabolin.
Like all anabolic steroids, it is a muscle-building chemical. It occurs naturally in the human body, but in minute quantities. It is rather similar in structure to testosterone, the male hormone.
Summary of anabolic steroids How they work:
They build power and strength. It elevates the natural testosterone levels, a hormone already present in the body. It increases body mass, muscle strength and muscle definition.
Nondrolone has many of the same effects as testosterone – muscle building – without some of the unwanted side-effects such as increased body hair and aggressive behaviour.
It is being examined in clinical trials as a possible treatment for wasting disease and to increase body tissue in HIV infected men.
Who takes these?
Athletes who need spurts of power for short, but intense contests; runners; swimmers; rowers; male gymnasts and weight and power lifters.
How is this substance traced?
Short-acting water-soluble steroids are now available. These can be absorbed by and eliminated from the body within a matter of hours. The most popular type is a synthetic derivative of testosterone.
It is detected in drug tests by the presence of its metabolite in the urine. A limit of two nanograms per millilitre of urine is the maximum concentration allowed in the human body. Some samples of athletes have shown levels up to 100 times above the “natural” levels.
In Sydney, during the Olympics, the ratio between testosterone and epitestosterone in urine was tested. The ratio should be 1:1 and, and in exceptional cases can occur naturally at the ratio of 4 or 5:1.
The cut-off point in Sydney was 6:1. By setting the cut-off point at such a high level, sports scientists are of the opinion that the IOC in actual fact tacitly consents to the use of anabolic steroids. – (Health24)
