Sports Enhancement (original) (raw)

From Bioethics Briefings

Highlights

Framing the Issue

Spring in America brings flowers, sweet warm breezes, and the thwack of a bat striking a baseball. The Mitchell Report, an early Christmas present to baseball fans released in December 2007, confirmed that a number of Major League players have used performance-enhancing drugs. Swings that would once have resulted in a fly ball to the warning track may now, with chemical assistance, deposit the ball in the bleachers.

Athletes using drugs to boost performance is hardly news. Anabolic steroids and stimulants have plagued the Olympics for decades. Professional cycling—including its premier event, the Tour de France—nearly collapsed over reports that drug use was widespread. Lance Armstrong, who won the Tour de France seven times, was exposed as a cheat and a bully.

An intriguing split has emerged in the public reaction to the use of performance-enhancing drugs in sport. For some, there’s not much to think about: the rules forbid anabolic steroids and other drugs; breaking the rules is cheating; cheating is wrong—end of story.

Others are not so sure. They raise a variety of objections. Some claim that athletes are just giving people what they want: fans enjoy home runs, athletes who take drugs such as anabolic steroids hit more home runs, what’s all the fuss? Of course the fans in the Roman Coliseum may have loved to see lions tearing the arms off Christians or gladiators hacking each other to death. So “what the fans desire” is not an ethically robust defense.

Others say that athletes should be free to do whatever they want to their own bodies. From this point of view, each athlete is best situated to balance the risks and benefits of using performance-enhancing drugs. The principal flaw in this argument is that it fails to understand that what one athlete chooses to do affects everyone in the competition. The athletes I know all crave a level playing field. If my competition is gaining an edge by using a drug that tilts the field in their favor, then their choice pressures me to do the same. Otherwise I may end up losing to someone who is less talented or less dedicated.

Why Prohibit Performance Enhancers?

Why prohibit certain performance aids in the first place? Sure, the rules of sport may ban anabolic steroids or synthetic hormones like human growth hormone (HGH), believed to enhance strength, and erythropoietin (EPO,) which stimulates the production of oxygen-carrying cells in the blood and thereby increases endurance. But what makes those means for improving performance bad while other things, from better equipment to more sophisticated training methods or nutrition regimens, are perfectly okay? What makes the use of performance-enhancing drugs in sport an ethical problem?

One common place to look for a response is the distinction between therapy and enhancement. Therapy is good, enhancement is suspect, right? Unfortunately, it’s not so clear or simple. The tools biomedical research creates to treat disease are completely indifferent to the fluid and sometimes disputed boundary between therapy and enhancement. A product like synthetic HGH can be in certain cases no more morally suspect than insulin for people with diabetes. For children who can’t make enough HGH themselves, the synthetic form can help replace what is missing. On the other hand, healthy athletes can use HGH to try to build larger-than-normal muscles. The HGH molecule neither knows nor cares whether it is helping a child inch towards normality or making a hugely muscled athlete even more muscular. Somewhere between the two, we’ve crossed the border from the friendly, familiar land of therapy to the unmapped, vaguely ominous terrain of enhancement.

Nor is biomedical enhancement obviously bad in all circumstances. Imagine a relatively innocuous drug that steadied a neurosurgeon’s hand so that her patients healed more rapidly with fewer complications: the ethics of that sort of performance enhancement would focus on whether neurosurgeons are ethically required to use the drug.

So the mere fact that some drugs enhance performance isn’t sufficient to decide whether they’re good, bad, or otherwise. The context matters. If it’s wrong for athletes to use performance-enhancing drugs, there must be something about sport that makes it so. I’ll discuss three characteristics of sport that provide the context and plausible justification for banning such drugs:

The Significance of Rules in Sport

Every sport has rules (with the possible exception of “Calvinball” from the comic strip “Calvin and Hobbes,” where the only rule is that you can’t use the same rule twice). The rules in each sport in effect determine which characteristics among all possible sources of difference influence who wins and who loses. Team A may be wealthier than Team B, but neither is allowed to bribe the umpire—a competition that Team A is likely to win.

Improvements in equipment can transform a sport. When pole-vaulters traded in their wooden poles for fiberglass ones, they were able to leap much higher. Swimmers at one time had suits available that allow them to slip through the water with a minimum of resistance. Those suits have now been banned from competition. Typically, sport deals with innovations in equipment in one of three ways.

Sometimes it embraces the new technology, as track and field did with fiberglass poles. The critical factors here were continuity and equal opportunity. Continuity was assured because the poles still required the same skills from pole-vaulters, such as speed down the runway, strength, and agility, so the s port continued to reward athletes with such skills. Equal opportunity meant that all athletes had to have access to fiberglass poles. The super-slippery swimsuits were rejected because they changed the meaning of the competition and allowed technology to trump ability.

Sometimes a sport accepts technological innovation as a part of the competition. Skiers use special combinations of waxes, bobsled teams compete to come up with the fastest sled. Even then, sports make and enforce rules. Athletes can compete on technology only up to a certain point: no motors allowed on bicycles, for instance.

Many innovations that would surely improve performance are banned outright. An athlete who showed up for the Boston Marathon wearing Rollerblades would be wheeled right off the start line. The marathon is for runners, not skaters. (Of course, one could try to organize a sport where Rollerbladers competed to cover the same course as the Boston Marathon; but that would be a different sport.) The Tour de France insists on a minimum weight for all bikes. As every road cyclist knows, the lighter the bike, the less energy required to climb the mountains that help make the Tour so famous and so difficult. This rule accomplishes two things. It neutralizes one advantage that the wealthiest or best-supported cyclists would gain by using fabulously expensive, custom-made parts of exotic metals or synthetics. It also protects cyclists against the temptation to shave every last gram off of critical components, increasing the risk of catastrophic failures when the bike is screaming down a switchback mountain road at 100 kilometers an hour.

Rules are changed at times to preserve a sport. Basketball banned goaltending—swatting the ball away just as it was about to go into the hoop—when players became so tall and athletic that they could stand by the basket and prevent most shots from having a chance to go in. Later, basketball created the three-second lane to keep offensive players from camping under the basket, and then the three-point line to reward good shooting and force defenders to venture out to the perimeter. These changes opened the game up for rapid cuts, screens, and sharp passes once again.

The Point of Sport: Natural Talents and Their Perfection?

In most sports—including all Olympic events—using performance-enhancing drugs is against the rules. But why? On what grounds does Nordic skiing ban EPO? What gives baseball the right to prohibit anabolic steroids?

If the point of an endurance sport like cross-country skiing is to see how rapidly you can cover long distances without collapsing, then anything that allows you to go harder and longer would improve your performance, including EPO. Why doesn’t Nordic skiing welcome EPO the same way it welcomes synthetic fiber garments and faster skis? To some critics, Nordic skiing is being inconsistent. If the point of the sport is to go faster, then EPO should be treated just like better ski waxes, the critic may argue.

But most aficionados of sport persist in seeing a difference between using drugs to enhance performance and employing other means to the same end. Intensive training, smart tactics, dedication, studying your competitors—all these can improve one’s performance and all of them are regarded as admirable ways of perfecting your natural talents.

Those natural talents are, of course, allotted in vastly uneven measure among us all. Some commentators see this as a form of injustice and performance-enhancing drugs as a remedy for nature’s cruel inequalities. Why should the race go to the swift? What if I’m a clumsy, slow-footed slogger? Shouldn’t I have an equal opportunity to get to the finish line first? If anabolic steroids or stimulants can balance out the uneven shares of talent given by birth, shouldn’t I be allowed to use them? Then victory will belong to the one who trains the hardest perhaps, talent be damned—or neutralized, at least.

When performance-enhancing drugs have the power to overcome differences in natural talents and the willingness to sacrifice and persevere in the quest to perfect those talents, we cannot avoid confronting the question, What do we value in sport? Emerging technologies—from hypoxic chambers and carbon fiber prostheses to genetic manipulation—will force us consider what, after all, is the point of sport?

Sport, the “Arms Race,” and the Triumph of the Performance Principle

When Hastings Center researchers spoke with athletes in the early 1980s about performance-enhancing drugs in sport, they described an intensely competitive world in which tiny differences—hundredths of a second in the hundred meter sprint, fractions of an inch in the discus or shot put—separated the victor from the vanquished. Anywhere a drug could give even a small edge, some athletes would be tempted to use it. And, just as significant, every other athlete in that event would feel enormous pressure to join in. The dynamics of drugs in sport bear more than a superficial resemblance to an arms race: each party drives the other further, lest either be left behind.

Critics of doping control sometimes argue that sport would be better off if athletes were just allowed to take whatever drugs they wanted. Fans would get more dramatic performances. The playing field would be leveled (because every athlete could use the same drugs). We could do away with the cat and mouse game between drug users and testers, saving money and aggravation.

These purported advantages would come at some cost. Sports that revere records and historical comparisons (think of baseball and home runs) would become unmoored by drug-aided athletes obliterating old standards. Athletes, caught in the sport arms race, would be pressed to take more and more drugs, in ever wilder combinations and at increasingly higher doses. While the scientific evidence that the drugs athletes use are harmful is often less conclusive than opponents of drugs in sport portray, that’s little reason for comfort.

Athletes often take drugs at multiples of the dosages that have been studied for their benefits and risks, and they take drugs in bizarre combinations. It’s unlikely that any research ethics committee would permit a scientifically controlled study that administered such large amounts and odd mixtures of drugs. So, yes, we should be concerned about risks to athletes, and we should perform whatever epidemiological and observational studies are possible under the circumstances. The drug race in sport has the potential to create a slow-motion public health catastrophe. Finally, we may lose whatever is most graceful, beautiful, and admirable about sport, which brings us back to the quintessential American game, baseball.

Emerging Challenges

When I was a kid my father, born in 1917, gave me the baseball glove he’d used as a young man. It was indeed a glove: leather, rather stiff, with short fingers and no webbing. I might has well have worn an oven mitt. Eventually I acquired a fielder’s glove more suited for baseball in the 1950s and 60s. The new glove enhanced my performance as an infielder—though not by much, at least not until my late teens when my scrawny body acquired a little muscle and coordination.

Modern baseball gloves—supple, long-fingered, webbed—allow fielders to snatch line drives and scoop up hard grounders with relative ease. They improve performance, no doubt. But infielders still have to get to the ball, catch it, and throw accurately to the base. They need quickness, agility, strength, and extraordinarily swift reaction times, qualities that great infielders have always possessed. This is one technology that has enriched rather than detracted from sport.

Sport as we know it faces emerging challenges on many fronts. To mention just a few:

Challenges for Policymakers and Journalists

For policymakers, two major categories of challenges emerge. The first set of challenges have to do with research. For decades the competition between drug-using athletes and their enablers on the one hand and antidoping workers on the other was uneven. The labs had to scramble to find any support for their research into new substances and new analytic methods. Dopers could make plenty of money supplying athletes seeking a competitive advantage. With the advent of new agencies such as the World Anti-Doping Agency (WADA) and the United States Anti-Doping Agency (USADA), a small but reliable stream of funds for research is now available. With better funding, much more could be done.

It could be very helpful to learn more about the culture of sports doping—why athletes dope, who influences their decisions, and the like. It would be equally interesting to do research to develop alternative strategies to encourage clean sport and discourage doping. Some promising ideas are being pursued, like the biological passport, which uses routine tests to establish physiological baselines; sharp departures from them signal pharmacological tampering. Other strategies should be encouraged and studied.

I pointed out earlier the difficulty of studying the risks when athletes use drugs in high dosages and novel combinations. We may not be able to construct an ethical clinical trial, but scientists can gather helpful data with other methodologies. Such research should be encouraged and funded.

The second major challenge is nontherapeutic drug use among adolescents. Various reports disagree about the percentages of teens using drugs such as anabolic steroids, but study after study shows alarming high levels of use. The research also reveals that young people may be more eager for the cosmetic effect—looking “buff” on steroids or HGH—than for any impact on performance. How to make such drugs less available and less attractive to adolescents is a significant policy challenge.

Finally, we must acknowledge the links between ethics, economics, and politics. Elite sport means big money. Success in international competitions can be a valuable political asset. Corruption plagues sport from college athletics to Olympic and professional organizations. We need a revolution in the governance of sport that demands honesty and accountability from all actors.

There are wide and vigorous disagreements on just about every matter I’ve touched. Let the dialogue flourish, and let the games begin.
