Performance enhancement -
Kind of a big deal. And I remember the first time I ever did it, the blood was pulled out in Spain, outside of Valencia, Spain, and it was put back into me three weeks later in the middle of the Tour de France.
So somebody had to transport that over an international border. Serious stuff, serious stuff. My life went from being a wide-eyed, green bike racer from Marblehead, Massachusetts to a few years later in a little bit of a dark world, very secretive, two different faces.
Cycling, all of a sudden, became different, it was more about results. After the season, which was probably my most successful season on record, I had great results, had a big Tour de France. I got back stateside after the season was over, it was in my off-season, and I realized I was having a hard time just getting out of bed, no motivation.
I mean, I thought about suicide, I drank to just check out at some points. I called them committee meetings and just kind of think about what I was up to and the consequences if it all went bad, how ugly that was going to look. And I had a bad reaction, my urine was like, black with dead red blood cells, I had a fever.
I told the team doctor about it and he watched over me. Luckily, it passed. But I remember thinking to myself, you know, what am I doing? What am I doing? This is a crazy world. But the power of the truth, I mean, the truth saved me. There was a federal investigation into Lance Armstrong and the U.
Postal Service Cycling Team. And a guy by the name of Jeff Novitsky contacted me, and I was forced to come in and tell the truth in front of a grand jury.
And finally, I got there in front of the grand jury and maybe the first 10, 15 minutes were a little bit hard, but then it was just like — PHEW — and it just came out, and for as hard as it was, it felt also just wonderful. But then I realized, wow, what an ugly situation this has been and ugly situation that we all went through.
From that moment on, really, being in that Los Angeles courtroom, I came out of there and I had a new perspective on what I was going to do with my life.
Hiding the truth was not included in that anymore. And the youngest asked me why I did it. I would say I take cycling a lot less seriously now, just kind of enjoy it a lot more.

Mood instability Impaired thinking and reading comprehension. Chemicals in this special class of steroids, which include testosterone, androstenediol, androstenedione, nandrolone and stanozolol, are credited with increasing muscle mass and strength, but drug tests can easily detect anabolic steroid abuse.
In the s and '90s, however, other doping alternatives started appearing on the scene. Now there are numerous PEDs that aren't classified as steroids. Their effects are quite varied, and some only benefit certain athletes playing certain sports.
That makes it extremely tricky for regulatory agencies like the International Cycling Union and the World Anti-Doping Agency WADA to keep up — and to keep drugs out of competing athletes. Today, WADA prohibits more than PEDs to some degree. New ones are constantly being developed, as are the methods used to detect them.
Red blood cells carry oxygen throughout the body, so it makes sense that if an athlete can increase their red blood cell count, they'll deliver more oxygen to their muscles and perform at a higher level.
Blood doping — removing and preserving a supply of blood so it can be returned, via transfusion, to the body right before competition — is one way to do this.
But it's messy and time-consuming. Taking erythropoietin , or EPO, increases red blood cell production without the need for transfusions.
The kidneys make the hormone naturally, although people with severe kidney disease don't produce enough. That's what the biotechnology firm Amgen was looking to address when it introduced synthetic EPO in By the s, though, cyclists and other endurance athletes discovered that they could train longer and harder if they took the drug regularly.
Not surprisingly, taking EPO comes with significant risk. Studies have shown that it increases the risk of events such as stroke, heart attack and pulmonary edema. One theory suggests that the drug thickens the blood to the point where it produces fatal clots. Such complications may have contributed to the deaths of at least 20 cyclists by , increasing the urgency to develop a reliable test to detect EPO [source: Zorpette ].
In , anti-doping agencies introduced the concept of a " biological passport ," a record of the substances found normally in an athlete's blood and urine, created by repeated sampling over time. By comparing the results of a blood test administered right before a competition to the passport, officials can determine if an athlete has been using EPO or other performance-enhancing drugs.
Like EPO, human growth hormone hGH occurs naturally in the body. In fact, the pituitary gland , the pea-sized organ located at the base of the brain, produces hGH to stimulate growth in children and adolescents and to increase muscle mass in adults.
As soon as synthetic hGH became available as a prescription medication in , when the U. Food and Drug Administration approved its use for a number of diseases that retard growth or cause muscle deterioration, athletes began eyeing it as a doping agent.
They figured it could mimic the muscle-building effects of anabolic steroids. At first, the high cost of the medication discouraged widespread use as a PED, but, as the saying goes, where there's a will to win, there's a way. The Summer Olympic Games have been called the "hGH Games" because of the rampant use of the drug among competitors.
And it continues to be a problem among athletes. In summer , Nigerian sprinter Blessing Okagbare was kicked out of the Tokyo Olympics after testing positive for hGH.
Today, athletes get hGH from a variety of sources: doctors willing to write prescriptions for off-label use, online pharmacies, illicit websites for performance-enhancing drugs and clinics that use the hormone to reverse the effects of aging. A few athletes even turn to black-market dealers that collect hGH from human cadavers.
It's a risky gamble, especially considering the lack of scientific evidence to suggest that hGH actually increases athletic performance. Oh, and don't forget the side effects. Using hGH has been linked to a variety of medical conditions, including joint pain, muscle weakness, fluid retention, carpal tunnel syndrome, cardiomyopathy and hyperlipidemia [source: Mayo Clinic ].
Another performance-enhancing drug that made the Summer Olympic Games memorable for the wrong reason was bromantane, a sort of stimulant and masking agent combined. Several Russians tested positive for the drug, which at the time was not included on the International Olympic Committee's IOC's list of banned substances.
That didn't stop the IOC from disqualifying several Russian athletes, stripping medals from two and ultimately blacklisting bromantane based on its performance-enhancing effects.
The effects of bromantane are quite unlike any other PED. Russian army doctors developed bromantane as a stimulant, something they could give to soldiers and cosmonauts to help them feel more alert and fight fatigue. Soon after, Russian athletes got hold of the drug, reporting that it helped them perform at peak levels without feeling exhausted.
Some anti-doping officials believe bromantane can hide the abuse of more serious drugs, such as steroids. Known as masking, this is just one more way athletes can find a way to cheat. For example, the masking agent probenecid stops the excretion of steroids for a few hours, decreasing the concentration of steroids in the urine.
The exact masking mechanism of bromantane, however, remains unclear. Bromantane gained popularity because it appealed on multiple fronts. But stimulants by themselves function reasonably well as performance-enhancing substances. Athletes take stimulants to improve athletic performance, reduce fatigue and increase aggressiveness.
And someone trying to qualify for a lower weight class may rely on stimulants for their ability to suppress appetite. You may think first of amphetamines — prescription-only "speed" pills — when you hear of this class of drugs, but not all stimulants require a physician's signature.
Ephedrine, for example, is available behind the counter in drug products, mostly as decongestants. Dietary supplements containing ephedrine are illegal in the U. Athletes, of course, aren't interested in these. They want ephedrine for an extra boost of energy despite the warnings that the drug can cause high blood pressure, dizziness, shortness of breath and cardiac arrhythmia.
Along with bromantane, diuretics have long served to mask steroid use. Diuretics are any drugs that affect kidney function, resulting in increased urine output. The "water pill" chlorthalidone , for example, prevents kidney tubules from reabsorbing fluids and salts and returning them to the blood.
As a result, more water leaves the body. In patients with certain conditions, such as heart disease, diuretics can also help control high blood pressure. But athletes who take anabolic steroids pop diuretics to dilute their urine, which decreases steroid concentration and makes it much more difficult to detect during drug testing.
Of course, there is testing for diuretics, too. Weightlifters and boxers may also down water pills to expel large amounts of fluid, which qualifies them to compete in a lower weight category.
Then, right before the match, they stop taking the pills to return to their heavier fighting weight, giving them an advantage against their opponent. However, an athlete taking diuretics may also get dizzy, become dehydrated or experience a severe drop in blood pressure — symptoms that make it hard to compete.

Clinics in Sports Medicine. In , Chandler and Blair 47 showed significant increases in knee extension strength, acceleration, anaerobic capacity, time to exhaustion during exercise, pre-exercise and maximum heart rates, and time to exhaustion during maximal oxygen consumption VO2 max testing after administration of 15 mg of dextroamphetamine versus placebo.
Most of the information to answer this question has been obtained in the past decade through studies of fatigue rather than an attempt to systematically investigate the effect of ADHD drugs on exercise. In , Roelands and colleagues 53 studied the effect of reboxetine, a pure NE reuptake inhibitor, similar to atomoxetine, in 9 healthy, well-trained cyclists.
They too exercised in both temperate and warm environments. They showed decreased power output and exercise performance at both 18 and 30 degrees centigrade.
Their conclusion was that DA reuptake inhibition was the cause of the increased exercise performance seen with drugs that affect both DA and NE MPH, amphetamine, and bupropion.
Frontiers in Integrative Neuroscience. Manipulations of dopaminergic signaling profoundly influence interval timing, leading to the hypothesis that dopamine influences internal pacemaker, or "clock," activity.
For instance, amphetamine, which increases concentrations of dopamine at the synaptic cleft advances the start of responding during interval timing, whereas antagonists of D2 type dopamine receptors typically slow timing; Depletion of dopamine in healthy volunteers impairs timing, while amphetamine releases synaptic dopamine and speeds up timing.

Dopamine stimulating drugs are known to enhance aspects of exercise performance Roelands et al. Sports Medicine Auckland, N. ISSN X. World Anti-Doping Agency. In recent decennia however, it became clear that the central nervous system plays an important role in the onset of fatigue during prolonged exercise Klass et al.
This indicates that subjects did not feel they were producing more power and consequently more heat. The authors concluded that the "safety switch" or the mechanisms existing in the body to prevent harmful effects are overridden by the drug administration Roelands et al. Taken together, these data indicate strong ergogenic effects of an increased DA concentration in the brain, without any change in the perception of effort.
The combined effects of DA and NA on performance in the heat were studied by our research group on a number of occasions.
Coinciding with this ergogenic effect, the authors observed core temperatures that were much higher compared with the placebo situation.
Interestingly, this occurred without any change in the subjective feelings of thermal sensation or perceived exertion. Similar to the methylphenidate study Roelands et al. Sports Health.

The present meta-analysis was conducted to estimate the magnitude of the effects of methylphenidate and amphetamine on cognitive functions central to academic and occupational functioning, including inhibitory control, working memory, short-term episodic memory, and delayed episodic memory.
In addition, we examined the evidence for publication bias. Forty-eight studies total of 1, participants were included in the analyses. We found evidence for small but significant stimulant enhancement effects on inhibitory control and short-term episodic memory. Small effects on working memory reached significance, based on one of our two analytical approaches.
Effects on delayed episodic memory were medium in size. However, because the effects on long-term and working memory were qualified by evidence for publication bias, we conclude that the effect of amphetamine and methylphenidate on the examined facets of healthy cognition is probably modest overall.
In some situations, a small advantage may be valuable, although it is also possible that healthy users resort to stimulants to enhance their energy and motivation more than their cognition. Earlier research has failed to distinguish whether stimulants' effects are small or whether they are nonexistent Ilieva et al.
The present findings supported generally small effects of amphetamine and methylphenidate on executive function and memory.
Specifically, in a set of experiments limited to high-quality designs, we found significant enhancement of several cognitive abilities. The results of this meta-analysis cannot address the important issues of individual differences in stimulant effects or the role of motivational enhancement in helping perform academic or occupational tasks.
However, they do confirm the reality of cognitive enhancing effects for normal healthy adults in general, while also indicating that these effects are modest in size.
