Erythropoietin initially proved very difficult to detect in doping athletes because it closely matches the hormone naturally occurring in the body. Not only that, but it disappears from the body within a few days. A test developed in Australia was first used at the Olympics in Sydney to identify erythropoietin in urine, but it did not identify any positives.

But the Australian experts from the Institute of Sport had also developed another method that could identify athletes who had used erythropoietin weeks before — by looking at how indirect markers in their blood had changed.

Cycling and athletics are the sports where hormones that increase oxygen supply are most often detected. Blood doping can cause heart attacks and stroke and many athletes have died after using erythropoietin.

Growth factors Scientists worked out how to make growth hormone to treat children with growth deficiencies. Athletes take growth hormone and other growth factors because they reportedly boost muscle mass and power.

But there is little clinical evidence these effects are real and growth hormone is most often used in a cocktail of drugs with steroids. Growth hormones are very hard to detect because they are present in the blood and urine at very low levels and disappear quickly from the bloodstream.

A growth hormone test was first used at the Beijing Olympics in and Russian powerlifters Nikolay Marfin and Vadim Rakitin were disqualified before the London Paralympics when they tested positive for it.

Side effects of growth hormone include high blood pressure, heart disease and diabetes. WADA also bans a range of drugs that alter metabolism. Masking drugs WADA has banned a series of drugs they call "masking agents", which make other banned drugs harder to detect.

Some masking agents act by stopping particular drug products forming in the urine. Plasma expanders work by increasing the volume of blood, which hides erythropoietin or other red blood cell boosters.

Diuretics, which boost urine production, are also classed as masking drugs. Australian swimmer Kylie Palmer withdrew from the Australian team last year after testing positive, with a minute amount of a diuretic found in her system.

AFP They were originally banned because they were thought to dilute the concentration of banned drugs in urine. This is less of a concern with more sensitive drug detection, but diuretics are still banned because they can cause fast weight loss in sports like boxing and weightlifting. Such weight loss would let an athlete unfairly compete in a lower weight category.

Australian Olympic team wrestler Vinod Kumar was suspended for four years last month following a positive drug test and will not compete for Australia in Rio.

According to media reports, he reportedly tested positive for a diuretic Uppers and downers Stimulants like amphetamines and cocaine can improve endurance, increase alertness and make athletes less tired.

Mixtures of stimulants, including the poison strychnine, heroin, cocaine and caffeine, were used by athletes until the s.

They are all banned by WADA, except for caffeine. Likewise, drugs that have a calming effect are also banned, but only in particular sports.

Beta-blockers are drugs that control heart rate, hand tremor and anxiety, an advantage in any sport where a steady hand is important. They are banned in archery and shooting, though only during competition, not in training.

North Korean shooting double medallist Kim Jong-Su was stripped of his medals at the Beijing Olympics after he tested positive for a beta-blocker. Chinese swimmer Sun Yang served a ban for taking trimetazidine, which the World Anti-Doping Agency previously classified as a stimulant but is now classed as a metabolic modulator.

It is used to treat angina, a heart condition that causes chest pain through lack of oxygen. In athletes it improves their oxygen use. Gene doping Gene doping is the new frontier of doping in sport. The idea is that a gene is transferred into the cells of the body to change the levels of genes and therefore proteins — to improve performance.

Jan 23,  · Special Series The Spotlight on Steroids and Sports A report from George Mitchell finds "widespread" use of performance-enhancing drugs in baseball. The first Olympic athlete to test positive for the use of performance-enhancing drugs was Hans-Gunnar Liljenwall, a Swedish pentathlete at the Summer Olympics, who lost his bronze medal for alcohol use, 'two beers to steady his nerves'. Aug 17,  · Among U.S. high school students, 4% to 6% of boys have used anabolic steroids, comparable to the rates of crack cocaine or heroin use. Among men in their 20s, that rate is even higher.

Gene therapy was developed to replace defective genes or proteins in people who have genetic diseases. Erythropoietin is an obvious target for gene doping and a genetically modified erythropoietin to treat anaemia in cancer patients has already been developed.

It works by adding a modified erythropoietin gene to the patient, which responds to low oxygen concentrations in the blood. Gene doping is very difficult to detect because the introduced genes cause proteins to be expressed that are very similar to those the body produces naturally.Jun 01,  · Comparative analysis of substance use and misuse in Olympic racket sports calls for a broader approach.

Athletes on the Anabolic Steroid Pump: A Review

Substance Abuse, Treatment, Prevention and Policy 6, 27 [ PMC free article ] [ PubMed ] Laure P., Binsinger C. (). Thus, the use of steroids was widespread in sports, as demonstrated at Mister America , in which 99% of the athletes reported the use of “Dianabol” [29].

Steroids. Anabolic steroids, a catch-all term for male hormones, are the oldest and still the most widely used banned drugs in sport — nearly half of banned substances detected in drug tests are steroids.

Testosterone is the most recognised doping steroid — it was first made in to treat men deficient in male sex hormones. At the end, we selected 92 articles with a history of anabolic steroids with the sport, methods and use, sporting performances as strength gains, hypertrophy, aerobic capacity and side effects, always connected to sports practice.

While you may think it is just big bodybuilders who use anabolic steroids or top track athletes who use performance enhancers, that’s not the case. Drug use is surprisingly . Abstract. Over the last decade the number of laboratories accredited by the International Olympic Committee (IOC) has grown to Nearly half of the ∼90 samples tested annually are collected on short notice—the most effective means to deter the use of anabolic androgenic steroids (AAS).
