Drug Use in Sports

My last round arguments was seen mostly jokes, But however in this round I will get more serious. DRUGS IN SPORT The use of performance enhancing drugs in the modern Olympics is on record as early as the games of the third Olympiad, When Thomas Hicks won the marathon after receiving an injection of strychnine in the middle of the race. 1 The first official ban on "stimulating substances" by a sporting organisation was introduced by the International Amateur Athletic Federation in 1928. 2 Using drugs to cheat in sport is not new, But it is becoming more effective. In 1976, The East German swimming team won 11 out of 13 Olympic events, And later sued the government for giving them anabolic steroids. 3 Yet despite the health risks, And despite the regulating bodies" attempts to eliminate drugs from sport, The use of illegal substances is widely known to be rife. It hardly raises an eyebrow now when some famous athlete fails a dope test. In 1992, Vicky Rabinowicz interviewed small groups of athletes. She found that Olympic athletes, In general, Believed that most successful athletes were using banned substances. 4 Much of the writing on the use of drugs in sport is focused on this kind of anecdotal evidence. There is very little rigorous, Objective evidence because the athletes are doing something that is taboo, Illegal, And sometimes highly dangerous. The anecdotal picture tells us that our attempts to eliminate drugs from sport have failed. In the absence of good evidence, We need an analytical argument to determine what we should do. CONDEMNED TO CHEATING? We are far from the days of amateur sporting competition. Elite athletes can earn tens of millions of dollars every year in prize money alone, And millions more in sponsorships and endorsements. The lure of success is great. But the penalties for cheating are small. A six month or one year ban from competition is a small penalty to pay for further years of multimillion dollar success. Drugs are much more effective today than they were in the days of strychnine and sheep"s testicles. Studies involving the anabolic steroid androgen showed that, Even in doses much lower than those used by athletes, Muscular strength could be improved by 5"20%. 5 Most athletes are also relatively unlikely to ever undergo testing. The International Amateur Athletic Federation estimates that only 10"15% of participating athletes are tested in each major competition. 6 The enormous rewards for the winner, The effectiveness of the drugs, And the low rate of testing all combine to create a cheating "game" that is irresistible to athletes. Kjetil Haugen7 investigated the suggestion that athletes face a kind of prisoner"s dilemma regarding drugs. His game theoretic model shows that, Unless the likelihood of athletes being caught doping was raised to unrealistically high levels, Or the payoffs for winning were reduced to unrealistically low levels, Athletes could all be predicted to cheat. The current situation for athletes ensures that this is likely, Even though they are worse off as a whole if everyone takes drugs, Than if nobody takes drugs. Drugs such as erythropoietin (EPO) and growth hormone are natural chemicals in the body. As technology advances, Drugs have become harder to detect because they mimic natural processes. In a few years, There will be many undetectable drugs. Haugen"s analysis predicts the obvious: that when the risk of being caught is zero, Athletes will all choose to cheat. The recent Olympic games in Athens were the first to follow the introduction of a global anti-doping code. From the lead up to the games to the end of competition, 3000 drug tests were carried out: 2600 urine tests and 400 blood tests for the endurance enhancing drug EPO. 8 From these, 23 athletes were found to have taken a banned substance"the most ever in an Olympic games. 9 Ten of the men"s weightlifting competitors were excluded. The goal of "cleaning" up the sport is unattainable. Further down the track the spectre of genetic enhancement looms dark and large. UNFAIR? People do well at sport as a result of the genetic lottery that happened to deal them a winning hand. Genetic tests are available to identify those with the greatest potential. If you have one version of the ACE gene, You will be better at long distance events. If you have another, You will be better at short distance events. Black Africans do better at short distance events because of biologically superior muscle type and bone structure. Sport discriminates against the genetically unfit. Sport is the province of the genetic elite (or freak). The starkest example is the Finnish skier Eero Maentyranta. In 1964, He won three gold medals. Subsequently it was found he had a genetic mutation that meant that he "naturally" had 40"50% more red blood cells than average. 15 Was it fair that he had significant advantage given to him by chance? The ability to perform well in sporting events is determined by the ability to deliver oxygen to muscles. Oxygen is carried by red blood cells. The more red blood cells, The more oxygen you can carry. This in turn controls an athlete"s performance in aerobic exercise. EPO is a natural hormone that stimulates red blood cell production, Raising the packed cell volume (PCV)"the percentage of the blood comprised of red blood cells. EPO is produced in response to anaemia, Haemorrhage, Pregnancy, Or living at altitude. Athletes began injecting recombinant human EPO in the 1970s, And it was officially banned in 1985. 16 At sea level, The average person has a PCV of 0. 4"0. 5. It naturally varies; 5% of people have a packed cell volume above 0. 5, 17 and that of elite athletes is more likely to exceed 0. 5, Either because their high packed cell volume has led them to success in sport or because of their training. 18 Raising the PCV too high can cause health problems. The risk of harm rapidly rises as PCV gets above 50%. One study showed that in men whose PCV was 0. 51 or more, Risk of stroke was significantly raised (relative risk R02;=R02; 2. 5), After adjustment for other causes of stroke. 19 At these levels, Raised PCV combined with hypertension would cause a ninefold increase in stroke risk. In endurance sports, Dehydration causes an athlete"s blood to thicken, Further raising blood viscosity and pressure. 20 What begins as a relatively low risk of stroke or heart attack can rise acutely during exercise. In the early 1990s, After EPO doping gained popularity but before tests for its presence were available, Several Dutch cyclists died in their sleep due to inexplicable cardiac arrest. This has been attributed to high levels of EPO doping. 21 The risks from raising an athlete"s PCV too high are real and serious. Use of EPO is endemic in cycling and many other sports. In 1998, The Festina team was expelled from the Tour de France after trainer Willy Voet was caught with 400 vials of performance enhancing drugs. 22 The following year, The World Anti-Doping Agency was established as a result of the scandal. However, EPO is extremely hard to detect and its use has continued. Italy"s Olympic anti-doping director observed in 2003 that the amount of EPO sold in Italy outweighed the amount needed for sick people by a factor of six. 23 In addition to trying to detect EPO directly, The International Cycling Union requires athletes to have a PCV no higher than 0. 5. But 5% of people naturally have a PCV higher than 0. 5. Athletes with a naturally high PCV cannot race unless doctors do a number of tests to show that their PCV is natural. Charles Wegelius was a British rider who was banned and then cleared in 2003. He had had his spleen removed in 1998 after an accident, And as the spleen removes red blood cells, Its absence resulted in an increased PCV. 24 There are other ways to increase the number of red blood cells that are legal. Altitude training can push the PCV to dangerous, Even fatal, Levels. More recently, Hypoxic air machines have been used to simulate altitude training. The body responds by releasing natural EPO and growing more blood cells, So that it can absorb more oxygen with every breath. The Hypoxico promotional material quotes Tim Seaman, A US athlete, Who claims that the hypoxic air tent has "given my blood the legal "boost" that it needs to be competitive at the world level. "25 There is one way to boost an athlete"s number of red blood cells that is completely undetectable:26 autologous blood doping. In this process, Athletes remove some blood, And reinject it after their body has made new blood to replace it. This method was popular before recombinant human EPO became available. "By allowing everyone to take performance enhancing drugs, We level the playing field. " There is no difference between elevating your blood count by altitude training, By using a hypoxic air machine, Or by taking EPO. But the last is illegal. Some competitors have high PCVs and an advantage by luck. Some can afford hypoxic air machines. Is this fair? Nature is not fair. Ian Thorpe has enormous feet which give him an advantage that no other swimmer can get, No matter how much they exercise. Some gymnasts are more flexible, And some basketball players are seven feet tall. By allowing everyone to take performance enhancing drugs, We level the playing field. We remove the effects of genetic inequality. Far from being unfair, Allowing performance enhancement promotes equality.
