Ergogenic steroids

Some steroids could be legal steroids or not banned from competitive sports. With athletes continuing to look for fresh ergogenic supplements for improving performance, athletic sports bodies would not stop reviewing every particular kind and determine if the aid offers an unfair benefit or may induce serious health issues in users. Although pharmacological drugs usage for increasing RBC count is not permitted in sports, athletes are not prevented from resting in hyperbaric chambers that pushes the body to make more RBCs. Referred to as hyperbaric oxygen therapy (HBOT), the therapy hasn’t been blacklisted from sports, despite it producing the results pretty much similar to the results of banned drugs.

The use of anabolic steroids is banned by all major sporting bodies, including the International Olympic Committee , Major League Baseball , the National Football League , the National Basketball Association , the National Hockey League , WWE , ICC , ITF , FIFA , FINA , UEFA , the European Athletic Association , and the Brazilian Football Confederation . Anabolic steroids are controlled substances in many countries, including Argentina, Australia, Brazil, Canada, the Netherlands (NL), the United Kingdom (UK) and the United States (.), while in other countries, such as Mexico and Thailand, they are readily available over-the-counter .

Anabolic steroids were first put to non-medical use among the Nazi troops of Germany in 1930s, to increase aggressiveness in them during the World War I. The German team were also found to bag the maximum medals in the following Olympics event held in 1936, in their own hometown. Later, however, these drugs had found their way into every sporting event as a result of their benefits of imparting increased bone mass & gaining lean muscle mass among athletes. These drugs, when had by athletes during the course of their training period, enhanced their on-field performance and boosted their self confidence of bagging the gold medal in major events conducted on a world wide level. It also enabled them to pump up muscle mass and gain lean body mass, without increasing or decreasing the fat mass in the body.

The preponderance of research to date suggests that exercise-induced reactive oxygen species and nitric oxide are beneficial. These free radicals induce adaptive changes in muscle that lead to greater production of mitochondria and hypertrophy of myofibers [ 17 , 21 , 23 , 24 ]. Exposure of cells to high concentrations of various antioxidant supplements (of which vitamins C and/or E have the most evidence) appears to blunt or block cell signaling and thereby inhibit some favorable physiological and physical adaptations to exercise. However, these adaptations might not prevent improvements in VO 2 max or endurance performance [ 25 ].

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.
