Final Individual Topical Paper: Performance Enhancement Drugs (PEDs)

Performance Enhancing Drugs- The evolution and future of drugs and how it has allowed humans to exceed their limitations[1]

Sam Lim Kok Wei (sam.lim.2013@economics.smu.edu.sg), 1st Year Student, School of Economics, Singapore Management University (SMU)

1. Executive Summary
Performance enhancing drugs (PED) has been used ever since men wanted to outperform each other. However, the general population have little or almost no knowledge about such PEDs and trust that athletes are drug free. Therefore, the author chose to write about this topic to raise awareness of the subject, PED, and hopefully provide insights into the current situation.

This paper will seek to understand the evolution of Performance Enhancing Drugs (PEDs) and the future implications that it will bring about. In order to gain a deeper understanding of PEDs, it is vital that we examine the historical aspect of it first. After which, the author would analyze the current situation on the use of performance enhancing drugs, and some of the social implications that have risen with the usage of PEDs. The author would also examine the current anti-doping policy and provide his inputs on the policy. Lastly, the author would like to present a future perspective on the use of PEDs, the author believes that we should embrace such advances due to the potential it could bring to our society.

2. Introduction

The World Anti-Doping Agency (WADA) defines Performance Enhancing Drug (PED) if it follows the three criteria. First, it has the potential to enhance or enhances sport performance. Second, it represents a potential or actual health risk. Third, it is contrary to the spirit of sport (WADA, 2003).

In the past, when we were still living in hunter gatherer times, we were judged based on how well we could hunt, fish and provide for our family. However, with civilization, we are no longer required to perform such tasks and instead we compete through sports. Due to the nature of humans’ attempt to establish their legacy and superiority through setting world records, spectators celebrate these records as it indicates human breakthroughs.

However, evolution doesn’t occur within the time frame of centuries, much less within decades. Athletes often realized that they are restricted by their natural abilities and found it tough to break barriers. Moreover, spectators have high expectations of athletes, they expect to witness records being broken every Olympic Games which is held once every 4 years. The stress of performing can come from various sources, from coaches, parents, personal pride and even media. These stress has pushed our athletes to engage in PEDs to unlock their potential by allowing them to train more frequently to push past their limit.

This paper will examine the historical use of PEDs, why some of them were invented and their purposes. Following which, it will examine the current situation and what are some social implications that has risen with usage of PEDs and how the current anti-doping policy is doomed to fail. This paper will also bring to you a future perspective of competition whereby we begin to embrace such advances and also the implications that come with it.

The limitations of this paper will encompass a lack of reliable resources to show the pervasive use of performance enhancing drugs as these are considered to be trade secrets of athletes. In addition, the author could have prior biasness against performance enhancing drugs as he is a competitive natural bodybuilder and powerlifter. In his field of sports, it is common practice to consume PEDs in order to maximize training frequency and intensity. Despite the limitations, the author has tried his best to provide an objective overview of the topic and his exposure to athletes who have used performance enhancing drugs has allowed him to provide clearer perspectives.

3. Historical Perspective

After feeling inspired by the Ancient Olympic Games, Baron Pierre de Coubertin established the Modern Olympic Games in 1894 (International Olympic Committee, 2012). It was common practice then for coaches to have their own unique mixture for their athletes to allow them to have an edge over their competition. In 1904, Thomas Hick, an Olympic marathon runner, was using a special concoction of brandy and strychnine which was supposed to boost his endurance (ProCon, 2013).

PEDs has been used since the start of the original Olympic Games, from 779 BC to 393 BC (ProCon, 2013). Early forms of PEDs were naturally occurring substances such as hydromel (an alcoholic beverage made from honey) and coffee. These early PEDs allowed users to have an edge over their competitors and outperform them as it gave the athletes heightened alertness and delayed their fatigue levels (ProCon, 2013).

In 1950s, athletes were using amphetamines to ward off fatigue and increase their alertness (Noakes, 2004). Amphetamines were created to treat attention deficit hyperactive disorder (ADHD) but were subsequently abused by athletes in order to better their competitors.

The explosion of PEDs happened in 1958, when Dr. John Bosley Zieglar introduced an androgenic anabolic steroid called dianabol after witnessing the success of Russian weightlifting team in the 1954 Olympic Games (Peters, 2005). This was made worse when the Food and Drug Adminstration (FDA) of the US approved the sale of steroids in 1958 after witnessing promising trials in other countries (ProCon, 2013). Dianabol also known as Methandrostenolone reacts strongly with the androgen receptors, which includes an increase in protein synthesis, and muscle strength over a short span of time (Dianabol, n.d). The effect is well observed in the bodybuilding scene where the use of drugs is pervasive. Let us examine 2 renowned bodybuilders. Steve Reeves in 1950 and Arnold Schwarnenegger in 1970s. Schwarnenegger admitted to steroid usage during his years as a champion bodybuilder. Objectively speaking, Schwarnenegger weighed 235lbs at a height of 6 feet 2 inches (Pro Profiles, n.d), while Steeve Reeves weighed 213lbs at a height of 6 feet 1 inches (BodybuildingPro, n.d). That is a difference of over 20lbs of muscles which accounts for almost 10% difference in muscle mass!

The pervasiveness of PEDs could also be observed in the sport of Track and Field. The 100m race held on 24th September 1988, at the Seoul Olympics has been labeled as the ‘dirtiest race in history’, six out of the eight contestants competing in the 100m race were linked to the usage of drugs (Moore, 2012). That race was considered as an utter disregard for ethics, fair play and honesty, as it has trampled on the Olympic values of friendship, respect and excellence (Moore, 2012). In particular, Ben Johnson, who was once regarded as the best sprinter in the world, has been caught doping not only once, but thrice! Johnson was tested positive for stanzolol, a synthetic anabolic steroid, at the 1988 Olympics. Subsequently, in 1999, he got tested positive for testosterone. Finally, Johnson got tested positive for a diuretic, a drug that increases the passing of urine, commonly used as a form of masking agent for other drugs to be flushed out of one’s system (Moore, 2012). From this example, we could see that elite athletes such as Johnson took up the calculated risk by taking PEDs in order to win the gold medal for honor and glory.

In 1990, United State Congress passed the first anabolic control act, placing anabolic steroids under Schedule III [2]of Controlled Substance Act (CSA) (ProCon, 2013). The objective of this was to reduce the use of anabolic steroids in competitive sports as well as restrict individuals from acquiring steroids for aesthetic purposes. While the intrinsic reason for banning of steroids is legitimate, the author feels that there was a lack of enforcement of this act, and we can observe this through the current situation of doping.

In 2002, Dr.Don Catlin identified norbolethone[3], the first reported designer steroid in an athlete’s urine sample. Designer steroids are anabolic steroids that are created to cheat drug tests (ProCon, 2013). Subsequently, in the years 2003 and 2004, more designer steroids were found. They were created with every intention to cheat the doping test and athletes that used these forms of designer steroids can be considered as deliberate cheaters (Groot and Koert, n.d). An example of an athlete whom used designer steroids would be Tammy Thomas, a former American Track and Field cyclist and a silver medalist at the 2001 UCI Track Cycling World Championships in the individual sprint event. She was eventually convicted of anabolic abuse and was banned from cycling for life (Williams, 2008). However, instead of feeling remorseful of her actions, she actually accused the jury of taking away her career away from her. What we can gather from this instance is that athletes feel that even with doping, they are playing at a fair level because they think that their fellow competitors are doping as well. As such, Thomas after being convicted, felt that she was unfairly judged and stormed away from the courtroom, casting light on the mentality of many of the world’s elite athletes today.

PEDs are not just used to enhance human abilities, they are being used to enhance race horses as well. In 2009, the winner of Kentucky Derby race was tested positive for steroids for the first time (ProCon, 2013). Big Brown’s trainer Rick Dutrow, was discovered to have administered stanozolol to his horses every 15th of the month (ProCon, 2013). With regards to injecting horses with steroids, it is not considered illegal. Animals are seen as mere objects for humans to use in order to win and injecting them with PEDs is considered a norm in order to stay competitive. However, the governing body of Australian horse racing is considering the ban of anabolic steroid use for their horses in a pledge for zero tolerance on PEDs (Drape, 2013).

After researching on these cases, the author is convinced that PEDs will continue to plague our sports industry even with increasingly stringent doping procedures. Therefore the author will examine the doping procedures later in this paper and determine if they are adequate, and if not, provide alternative solutions to this conundrum.

4. Current Perspective:

In this column, the author will examine firstly, how athletes are able to abuse PEDs without getting caught. Secondly, the transition from using anabolic steroids to Human Growth Hormones (HGH). Lastly, he will examine the doping procedures and determine if they are adequate in curbing PEDs.

4.1 How athletes are able to abuse PEDs without getting caught
In particular, we will examine the case of Lance Armstrong, winner of 7 Tour De France, got caught for doping (Albergotti & O’Connell, 2012). How is it possible, for someone to have passed all the doping tests while competing over the span of a decade only to get busted later on? Lance Armstrong decided to come clean only after being accused of doping by his former teammate, Floyd Landis. Initially, the accusations from Mr Landis were just sent to a small group of cyclist but it was eventually made public by Wall Street Journal (CNN, 2010). Mr Landis accused Armstrong of using a performance enhancing cocktail that consisted of Erythropoietin[4] (EPO), Human Growth Hormones, testosterone and blood transfusion (CNN, 2010). These drugs were used and monitored closely by his team’s doctor who had expertise knowledge in these drugs and were able to manipulate Armstrong’s hormonal level to cheat doping tests. For example, EPO boosts red blood cell counts giving the user an enormous endurance advantage (Yahoo News, 2012). However, before the year 2000, doping tests were unable to distinguish the synthetic hormone apart from its natural counterpart. As such, as long as athletes were able to keep their hematocrit[5] in an acceptable range (below 50%), they could use EPO to boost their red blood cell counts. Another drug that was abused would be testosterone. Testosterone is known to be the most anabolic hormone inside the human body. It allows one to pack on muscle mass, increases the formation of red blood cells, and decreases recovery time (Shugarman, n.d). However, testosterone levels vary from person to person, and having an accurate baseline level would be near impossible. Athletes in the 2012 Olympics were allowed to have four times the normal levels of testosterone before they tipped a drug test (Yahoo News, 2012). Therefore, it is possible for athletes to abuse testosterone in small dosages to give themselves a competitive edge, yet not test positive for it. Athletes are still subjected to surprise doping tests, but similarly, they have a counter measure to these tests. Team doctors would dilute their blood with saline solution to quickly drive down hematocrit level allowing them to pass both the EPO and blood transfusion tests (Yahoo News, 2012).
Through this case study, the author wishes to highlight the limitations of anti-doping tests and how athletes are able to find and exploit loopholes.

4.2 Advances of PEDs to Human Growth Hormones
According to Holt, the Human Growth Hormone is a naturally occurring peptide hormone produced by the anterior pituitary gland (Holt, 2011). It was an arduous and complicated task trying to acquire GH back in the 1940s because it had to be isolated from the human pituitary gland and it was extremely limited (Ayyar, 2011). Usage of GH was strictly limited to research or therapeutic purposes. However, this changed in 1985 when they innovated the biosynthetic human growth hormones also known as somatropin (Ayyar, 2011). They were able to synthetically create a protein that is nearly identical to the main form of the naturally occurring human growth hormone.

However, athletes who were trying to pursue their dreams, abused this drug. The most famous case of GH abuse surfaced in 1988 following Ben Johnson’s steroid scandal. Both he and his coach admitted under oath that Johnson was taking a mix of GH and anabolic steroids (Guha et al., 2010). Another example would be Canadian sprinter Angella Issanjenko who also admitted to using HGH along with other drugs (Holt, 2011). It is believed that athletes switched from anabolic steroids to HGH as it was considered highly undetectable and their doping tests included a blood test that was extremely costly (Holt et al., 2009).

4.3 Anti-doping bound to fail











Figure 1: Olympic Drug Testing Chart.
Reproduced from CBS news (n.d)

Upon researching into the anti-doping system in sports, the author has concluded that it is inadequate and bound to fail. The actual rate of success of anti-doping testing in some cases has been said to be less than 10% and less than 50% on average (Hermann & Henneberg, 2013). From Figure 3, the number of athletes that got tested positive for steroids in the 2004 Athens game is 0.008%! This shows that the probability of getting tested positive is extremely small. There are several components to which an athlete has to commit in order to test positive. They are namely the window of detection, test sensitivity, how often doping occurs and test predictability (Hermann & Henneberg, 2013). The probability in which anti-doping agencies can successfully determine which athlete is doping is extremely small. Furthermore, the cost of urine testing an athlete per year is approximately 21,190.86 euros (Hermann & Henneberg, 2013). As such, in Germany where there is approximately 4000 athletes, the total cost of testing every one of them would exceed 84 million euros (Hermann & Henneberg, 2013)! However, the total annual revenue for the Nationale Anti-Doping Agentur Germany in 2011 was approximately around 4.5 million euros, which would result in close to 80 million euros shortfall (Hermann & Henneberg, 2013)! Therefore, with the lack of appropriate funding, they could only handpick random athletes to conduct tests on them. This is inadequate. In order to have a fair and level playing field, every athlete has to be tested and ensure they are not on any PEDs. With that said, even with testing, the probability of ensuring that every athlete competing is drug-free is extremely slim as athletes could also have used cleansing or masking drugs to cheat the anti-doping tests.

5. Future perspectives

Looking into the future, PEDs will only become more sophisticated and becoming increasingly difficult to detect. With gene therapy already in place, there is no stopping athletes to abuse this aspect of technology. Instead of injecting synthetic Erythropoietin (EPO) into their bodies, they could opt to upgrade the gene responsible for producing more red blood cells (Naam, 2005). Investing more money into anti-doping test is akin to throwing money at an abyss. Even with anti-doping tests in place and banning of such substances, athletes will still take the calculated risk and engage in PEDs in order to have competitive advantage. Therefore the author suggests creating sub-categories for athletes to compete in: natural, enhanced or prosthetic/genetically-enhanced athletes.

5.1 Sub category for competition

Before the introduction of sub categories, we must first acknowledge that PED usage is pervasive and will not stop. Instead of penalizing the usage of PEDs, we should supervise athletes who have decided to go down this road. These categories should be considered mutually exclusive with no basis of comparisons even if they are competing in the same sport or event. There should not be any discrimination of athletes in any categories because it is considered as their choice and they are fully aware of the risks that they are undertaking
For natural athletes, this category still require some forms of anti-doping measures, however it should be reserved for the top athletes who has a higher probability of doping. The results of this category could be used to compare across different eras of athletes. This category of natural competition can already be observed in the bodybuilding arena. There are professional natural bodybuilding federations such as the Professional Natural Bodybuilding Association (PNBA), World Natural Bodybuilding Federation (WNBF) and International Natural Bodybuilding Association (INBA) are some avenues for natural athletes to compete in. They do not explicitly state that other bodybuilding shows are plagued with PEDs, but rather, they acknowledge the fact that PEDs are rampant and provide an alternative avenue for natural athletes to compete in.

How about in Singapore? The recent scandal of Singapore Bodybuilding Federation (SBBF) being delisted by Singapore Sports Council after failing to explain a number of controversies, including doping at the Singapore National Bodybuilding and Physique Sports Championships. In addition, 7 bodybuilding athletes got tested positive for prohibited substances and received a two-year ban (Singapore Sports Council, 2012). The author feels that such a ban would not discourage further usage of PEDs because it is common knowledge that bodybuilders use such anabolics to prepare themselves for competition. These banned athletes would simply treat this 2-year ban as a good time to indulge in even more anabolic steroids and return even better than before. As such, the author feels that instead of imposing just a 2-year ban, Singapore should have imposed a heavier penalty such as a life-time ban. Singapore could be the venue for drug free competition. We could be the first to host natural competitions in South East Asia (SEA) once our national stadium is built, and if any athletes were found to be using PEDs, they would be subjected to a lifetime ban and never to return to Singapore to compete again. Such a ban could create a new arena for natural athletes in SEA to aspire to compete in.

For enhanced athletes, this is a category whereby the athletes understand the risks involved with the consumption of such PEDs and still wish to do so. It can be assumed that all athletes participating in the enhanced categories are under the influence of PEDs and their results may not be a good gauge of athletic performance throughout the years as PEDs continue to advance and have even greater effects on human performance. Most of the anti-doping funds could be channeled into this category. It could be used to provide athletes with proper doctor supervision of their PEDs. This category of athletes will allow doctors to experiment with different drug usage and witness for themselves the effects of their drugs. Spectators who constantly demand more out of an athlete could be enticed to sponsor these athletes as they push the boundaries of human capabilities and excite us with even more breath taking records.

Lastly, the most controversial category for prosthetic or genetically enhanced athletes. This category of athletes would have undergone either genetic manipulation or have enhanced prosthetics limbs. With gene therapy already in place, it is not a longshot to say that gene manipulation could be right around the corner. Gene manipulation will be possible in the near future, creating a scenario where genes that control the production of red blood cells could be upgraded and essentially these athletes could have superhuman regenerative abilities (Naam, 2005). How about enhanced prosthetics? Robotic arms or legs that outperform human limbs? The well-known blade runner Oscar Pistorius who’s an amputee that competes in the normal Olympics, has caused a huge dispute over his prosthetics. He runs with J-shaped carbon fibre prosthetics called the “Flex-Foot Cheetah”, developed by biomedical engineer Van Philips and manufactured by Ossur (Sokolove, 2012). Pistorius used significantly less oxygen than able-bodied sprinters, 25% less during sprinting and 17% less during jogging (Tucker & Dugas, 2011). How about the controversial swimsuit, LZR, which allowed our athletes to break numerous world records at the 2008 Beijing Olympics? The swimsuit was able to compress a swimmer’s body into a streamlined tube and trapped air, the former will reduce drag while the latter will provide buoyancy that was unmatched (Kessel, 2008). 23 out of 25 world records broken was done when LZR was worn (Paxman, 2011). FINA, swimming’s world governing body, decided to ban the LZR suit as it was considered as ‘technology doping’ (Shipley, 2009). With this category in place, we will no longer be impeding the advances of technology and engineers will be free to invent such attachments. However, in order to ensure fair play amongst athletes in this category, all of the athletes should be using the exact same attachments, to ensure no discrepancies in their performances and also consistent competing criteria. This category will also expedite the innovation process where engineers are able to bring their products to the market as they now have the incentive to do so.

5.2 Ethics of PEDs usage
Some argue that athletes using PEDs are considered as cheaters and ethically wrong because they have an unfair advantage over their competitors. However, the underlying assumption is that other competitors are not under the influence of PEDs, this is usually not the case. Just look into the controversial baseball PED scandal in America, where Major League Baseball (MLB) stars Alex Rodriguez, Gio Gonzalez and Barry Bonds are tied to the steroid scandal. Another case would be seven times Tour De France champion Lance Armstrong, once looked upon as the best cyclist we ever had eventually admitted to the use of PEDs. The author is trying to highlight that competition is extremely stiff, especially so when there is fame and money attached to it. Therefore, spectators should acknowledge that athletes are willing to take that calculated risk in order to win and gain fame or success in their sport. However, we could solve this ethical issue of PED usage with the aforementioned sub category competitions.  The author feels that taking PEDs is a personal choice, and PEDs are by no means a miracle drug, athletes that consume PEDs train more frequently and intensely than drug-free athletes.

6. Conclusion

Encapsulating the aforementioned, the author has examined the development of Performance Enhancing Drugs, from the invention back in 1958 to the evolution into Human Growth Hormones in 1985. Currently, we are labeled as the steroid era, whereby there is no sport that has not been tainted by the use of PEDs. This is due to the competitive nature of humans wanting to outperform each other, even at the expense of using PEDs. Even in Singapore, the advent of PEDs can be seen by our local bodybuilders testing positive for their doping tests (Singapore Sports Council, 2012). Furthermore, the author has looked into the anti-doping policy and found that it is inadequate. He has provided a viable option to create sub categories for athletes to compete in, this would not only solve ethical issues concerning PEDs but also a reallocation of resources to ensure the health of our athletes while promoting the spirit of sports at the same time.

Through this paper, the author wishes to raise awareness regarding the prevalence of PEDs and the ignorance that the general public have about their athletes. He feels that resisting PEDs is a lost cause which would result in the loss of millions of dollars and still provide no concrete solution to this conundrum. Therefore, he urges the general public to become more receptive of PEDs, as this will allow our athletes to come clean with their PED usage and engage in doctor supervision.
