In competitive sports, doping is the use of banned athletic performance-enhancing drugs (PEDs) by athletes as a way of cheating. As stated in the World Anti-Doping Code by WADA, doping is defined as the occurrence of one or more of the anti-doping rule violations outlined in Article 2.1 through Article 2.11 of the Code. The term doping is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical and is prohibited by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating.

The origins of doping in sports go back to the creation of the sport itself. From ancient usage of substances in chariot racing to more recent controversies in doping in baseball, doping in tennis, doping at the Olympic Games, and doping at the Tour de France, popular views among athletes have varied widely from country to country over the years. The general trend among authorities and sporting organizations over the past several decades has been to regulate the use of drugs in sports strictly. The reasons for the ban are mainly the health risks of performance-enhancing drugs, the equality of opportunity for athletes, and the exemplary effect of drug-free sports for the public. Anti-doping authorities state that using performance-enhancing drugs goes against the "spirit of sport".

History The use of drugs in sports goes back centuries, about back to the very invention of the concept of sports. In ancient times, when the fittest of a nation were selected as athletes or combatants, they were fed diets and given treatments considered beneficial to help increase muscle. For instance, Scandinavian mythology says Berserkers could drink a mixture called "butotens" to greatly improve their physical power at the risk of insanity, which is thought to have been prepared using the Amanita muscaria mushroom.

The ancient Olympics in Greece have been alleged to have had forms of doping. In ancient Rome, where chariot racing had become a huge part of their culture, athletes drank herbal infusions to strengthen them before chariot races.

From that moment, people started to introduce their specific diets to improve their performance. Lots of athletes were mainly focusing on achieving superiority and winning the competition by increasing muscle strength capacity and endurance. Charmis, the Spartan winner of the Stade race in the Olympic Games of 668 BC, introduced the special diet of consuming enough dried figs during the training period.

A participant in an endurance walking race in Britain, Abraham Wood, said in 1807 that he had used laudanum (which contains opiates) to keep him awake for 24 hours while competing against Robert Barclay Allardyce. By April 1877, walking races had stretched to and the following year, also at the Agricultural Hall in Islington, London, to . The Illustrated London News chided:

It may be an advantage to know that a man can travel 520 miles in 138 hours, and manage to live through a week with an infinitesimal amount of rest, though we fail to perceive that anyone could possibly be placed in a position where his ability in this respect would be of any use to him [and] what is to be gained by a constant repetition of the fact.Grajewski, Tadeusw: The Building That Would Not Go Away, Royal Agriciultural Hall, UK, 1989

The event proved popular, however, with 20,000 spectators attending each day.Woodland, Les: This Island Race, Mousehold Press, UK, 2005 Encouraged, the promoters developed the idea and soon held similar races for cyclists.

"...and much more likely to endure their miseries publicly; a tired walker, after all, merely sits down – a tired cyclist falls off and possibly brings others crashing down as well. That's much more fun".

The fascination with six-day bicycle races spread across the Atlantic and appealed to the crowds in America as well. And the more spectators paid at the gate, the higher the prizes could be and the greater was the incentive of riders to stay awake—or be kept awake—to ride the greatest distance. Their exhaustion was countered by soigneurs (the French word for "healers"), helpers akin to seconds in boxing. Among the treatments they supplied was nitroglycerine, a drug used to stimulate the heart after cardiac attacks and which was credited with improving riders' breathing.Novich, Max M., Abbotempo, UK, 1964 Riders had hallucinations from the exhaustion and perhaps the drugs. The American champion Major Taylor refused to continue the New York race, saying: "I cannot go on with safety, for there is a man chasing me around the ring with a knife in his hand."Bearings, US, 24 December 1896, cited Ritchie, Andrew, Major Taylor, Bicycle Books, US, 1988

Public reaction turned against such trials, whether individual races or in teams of two. One report said:

An athletic contest in which the participants 'go queer' in their heads, and strain their powers until their faces become hideous with the tortures that rack them, is not sport, it is brutality. It appears from the reports of this singular performance that some of the bicycle riders have actually become temporarily insane during the contest... Days and weeks of recuperation will be needed to put the racers in condition, and it is likely that some of them will never recover from the strain.New York Times, US, 1897, cited McCullagh, James, American Bicycle Racing, Rodale Press, U.S., 1976

The father of anabolic steroids in the United States was John Ziegler (1917–1983), a physician for the U.S. weightlifting team in the mid-20th century. In 1954, on his tour to Vienna with his team for the world championship, Ziegler learned from his Russian colleague that the Soviet weightlifting team's success was due to their use of testosterone as a performance-enhancing drug. Deciding that U.S. athletes needed chemical assistance to remain competitive, Ziegler worked with the CIBA Pharmaceutical Company to develop an oral anabolic steroid. This resulted in the creation of methandrostenolone, which appeared on the market in 1960 under the brand name Dianabol. During the Olympics that year, the Danish cyclist Knud Enemark Jensen collapsed and died while competing in the 100-kilometer (62-mile) race. An autopsy later revealed the presence of amphetamines and a drug called nicotinyl tartrate in his system.

The American specialist in doping, Max M. Novich, wrote: "Trainers of the old school who supplied treatments which had cocaine as their base declared with assurance that a rider tired by a six-day race would get his second breath after absorbing these mixtures."Novich, ibid. Cited De Mondenard, Dr Jean-Pierre: "Dopage, l'imposture des performances", Chiron, France, 2000 John Hoberman, a professor at the University of Texas in Austin, Texas, said six-day races were "de facto experiments investigating the physiology of stress as well as the substances that might alleviate exhaustion."Hoberman, John; Dopers on Wheels: The Tour's sorry history, MSNBC/id/19462071/ retrieved December 2007

Prevalence Over 30% of athletes participating in 2011 World Championships in Athletics admitted having used banned substances during their careers. According to a study commissioned by the World Anti-Doping Agency (WADA), actually 44% of them had used them. Nevertheless, only 0.5% of those tested were caught.

The entire Russian track and field team was banned from the 2016 Olympic Games, as the Russian State had sponsored and essentially sanctioned their doping program.

Goldman's dilemma

Goldman's dilemma, or the Goldman dilemma, is a question that was posed to elite athletes by physician, osteopath and publicist Bob Goldman, asking whether they would take a drug that would guarantee them success in sport, but cause them to die after five years. In his research, as in previous research by Mirkin, approximately half the athletes responded that they would take the drug, but modern research by James Connor and co-workers has yielded much lower numbers, with athletes having levels of acceptance of the dilemma that were similar to the general population of Australia.

Substances

The most common prohibited substances for doping in sport are: Anabolic steroids (most common), which increase muscle mass and physical strength. Stimulants (second most common), which increase excitement and decrease the sensation of fatigue. Examples of well known stimulants include caffeine, cocaine, amphetamine, modafinil, and ephedrine. Caffeine, although a stimulant, has not been banned by the International Olympic Committee or the World Anti Doping Agency since 2004. It has a positive effect on various physical parameters, most of all endurance, but also on velocity, strength, reaction time and specific actions like throwing performance.

Other ways of cheating that change the body without using foreign substances include injecting one's own red blood cells as done with doping at the Tour de France, treating blood with UV light or the use of a hyperbaric chamber (not currently banned), and, potentially, gene doping.

Anabolic steroids

Anabolic-androgenic steroids (AAS) were first isolated, identified and synthesized in the 1930s, and are now used therapeutically in medicine to induce bone growth, stimulate appetite, induce male puberty, and treat chronic wasting conditions, such as cancer and AIDS. Anabolic steroids also increase muscle mass and physical strength, and are therefore used in sports and bodybuilding to enhance strength or physique. Known side effects include harmful changes in cholesterol levels (increased low-density lipoprotein and decreased high-density lipoprotein), acne, high blood pressure, and liver damage. Some of these effects can be mitigated by taking supplemental drugs.

AAS use in American sports began in October 1954 when John Ziegler, a doctor who treated American athletes, went to Vienna with the American weightlifting team. There he met a Russian physician who, over "a few drinks", repeatedly asked "What are you giving your boys?" When Ziegler returned the question, the Russian said that his own athletes were being given testosterone. Returning to America, Ziegler tried low doses of testosterone on himself, on the American trainer Bob Hoffman and on two lifters, Jim Park and Yaz Kuzahara. All gained more weight and strength than any training programme would produce but there were side-effects.Laure, P.: Les répresentations du dopage; approche psycho-sociologique, Thèse STAPS, Nancy, France, 1994 Ziegler sought a drug without after-effects and hit upon the anabolic steroid methandrostenolone, first made in the US in 1958 by Ciba and marketed as Dianabol (colloquially known as "d-bol").

The results were so impressive that lifters began taking more, and steroids spread to other sports. Paul Lowe, a former running back with the San Diego Chargers American football team, told a California legislative committee on drug abuse in 1970: "We had to take them [steroids] at lunchtime. He [an official] would put them on a little saucer and prescribed them for us to take them and if not he would suggest there might be a fine."
