Anabolic androgenic steroids (AAS) were initially created for therapeutic purposes, and synthetic derivatives of the male hormone testosterone. Due its great anabolic effects, these drugs are being used on a large scale, for the improvement of sports performance. In this present study, we aim to show the history of it’ use, present their mechanisms of action, more particularly its use correlate with improved body composition, muscle mass, aerobic capacity and verify their possible side effects, analyzing their use therapeutic and indiscriminate, through direct scientific research with the sports. Sources were reviewed scientific the following search engines: PUBMED, LILACS and SCIELO. The results showed that in presence of a suitable AAS and diet can contribute to increases in body weight, particularly lean body mass and muscle strength gains achieved by high intensity exercise, these effects can be further potentiated, the use of supraphysiological doses, but in the aspect of aerobic power, there are not scientific evidence to support their improvement. Regarding side effects, the use of AAS, is related to several complications in the liver, cardiovascular system, reproductive system and psychological characteristics, always assigned by the non-therapeutic and abuse of AAS. Thus we conclude that the use of AAS, are directly linked to gains muscle mass, strength, as well several side effects, always assigned to abusive and indiscriminate doses, it is noteworthy that the scientific literature, still has a certain lack of studies, mainly randomized, controlled, with supraphysiological doses in human, so many effects are still unknown.
@Geoff: so people are “fucken idiots” if they think The Rock used steroids? I’m terribly sorry to be the one to give you this reality check, Geoff, but you’re in dire need of it, so here goes; I’ve been doing bodybuilding for more than 15 years and I can tell you from my own experience that a lot of the stuff that you see on “natural” stages is often not natural at all – you should really get a grip on reality. Sadly enough, quite a lot of the “natural” guys (I wouldn’t say the majority) do a cycle during the off season and try not to test positive during the competitions (which has gone wrong on more than one occasion). I don’t have a problem with people using non-natural bodybuilding regimes, not at all, but don’t take part in natural competitions if you do, that’s all; go for the non-natural competitions or simply don’t compete. Furthermore, most of the “natural” bodybuilders are not bigger than the Rock; they might be more cut, true, and you might confuse this with “being big,” but most of them are definitely not bigger, volume- and mass-wise. And as far as the Rock’s steroid’s usage is concerned: he apparently admitted to this himself (which, again, is not a “bad thing” in my opinion; to each his own, after all), just check (for example) http:///articles/140046-dwayne-the-rock-johnson-says-he-used-steriods-is-it-just-his-era-that-used .
