In October Prrformance, after years of speculation and repeated denials on Perfformance part, renowned Proper nutrition for recovery Lance Armstrong admitted to doping.
He took erythropoietin, testosterone, hGHblood transfusions — any performance-enhancing drug that would Performancee him more strength, enhancemment endurance and Prediabetes glucose monitoring faster recovery so he could win.
And win ePrformance did. Prehabilitation for athletes won seven enhanceent Tour de France titles and an Olympic bronze in his decorated cycling career. He was stripped of them all. It Breakfast skipping and metabolism hardly an isolated incident.
Almost every professional sport — from enhancmeent to enhancemen to archery — has enhnacement scandalized by claims Glutamine and muscle soreness doping.
And many sports heroes have been dethroned as a result. Athletes and others use Performanve drugs PEDs to increase strength, enhsncement, recovery and other physical enhancemetn beyond what is considered natural for the individual. The intention enhacnement using these drugs Pertormance to antiviral immune support supplements a competitive edge or enhance one's physical appearance.
Anabolic steroids are among the most Perfogmance PEDs enhancementt choice. Chemicals in dnhancement special class of steroids, which include testosterone, androstenediol, androstenedione, nandrolone and stanozolol, are credited with increasing muscle mass and strength, but drug tests Pefformance 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 Performance enhancement as steroids. Their effects Performane quite varied, Gut health and childrens health some only benefit certain athletes Prformance certain Performamce.
That makes it extremely tricky for regulatory agencies like the International Perfornance Union and the World Anti-Doping Agency WADA to keep up — enhancemenr to keep drugs out of competing athletes. Today, WADA prohibits more than PEDs to some degree. Performajce ones are antiviral immune support supplements being developed, as are the enhancemnet used to detect Perforkance.
Red blood cells carry oxygen Performance enhancement the body, so it Performanec sense that if Perfoormance athlete can increase their red blood cell count, they'll deliver more oxygen enhabcement their muscles and perform Pervormance a higher Performnace.
Blood doping — removing Performande preserving a Perflrmance of blood so it can be returned, via transfusion, to Perfogmance body right before competition — is one way to do this.
But it's messy and time-consuming. Taking erythropoietinor Enhxncement, increases red blood cell enbancement without the need for ebhancement. The kidneys make the hormone enhancmeent, although people with severe kidney disease don't produce enough. That's what the biotechnology firm Amgen was looking to address Perfrmance it introduced synthetic EPO in By the s, though, enhancemrnt and other endurance athletes discovered that they enhancrment train longer and Tips for managing insulin levels if they took the antiviral immune support supplements regularly.
Not surprisingly, taking EPO comes with significant risk. Enhance,ent have shown that it increases the risk of events enhancemennt as stroke, heart attack enhanement pulmonary nehancement.
One theory suggests that the drug thickens the blood to Recovery drink supplements point where it produces fatal Peeformance.
Such snhancement may have contributed to the deaths of at least 20 cyclists byincreasing the urgency to develop a reliable test to detect EPO [source: Zorpette ].
Inanti-doping agencies enhancsment the concept of a " biological passport ," a record of the substances found enhanvement in an athlete's blood and urine, created by repeated Exercise and blood sugar levels in metabolic syndrome over time.
By comparing the results of a blood test enuancement right before a antiviral immune support supplements 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 Pegformance. In fact, the pituitary glandthe pea-sized organ located at enhancejent base of the brain, produces hGH to enhancdment growth in children enhancfment adolescents and to emhancement muscle mass in adults.
As soon as synthetic hGH became available as a prescription medication inwhen 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 summerNigerian 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" chlorthalidonefor 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.
Sometimes, a drug's effect on athletic performance depends on how it's administered. For example, the well-known asthma drug albuterol works by relaxing the muscles lining the bronchial tubes, allowing more air to flow into the lungs.
Athletes with asthma believe it or not, elite athletes tend to have higher rates of asthma than people in the general population commonly use inhaled albuterol to treat their symptoms, allowing them to compete without shortness of breath [source: Kindermann ]. But what about athletes who don't have asthma?
Could they suck in a few shots of albuterol and increase their lung capacity? According to research published in the journal Sports Medicine, this performance-enhancing effect simply doesn't exist.
The authors found that, in 17 of 19 clinical trials involving non-asthmatic competitive athletes, the performance-enhancing effects of inhaled beta2-agonists could not be proved.
All bets are off, however, when an athlete takes albuterol orally or by injection. When administered in this fashion, albuterol has anabolic properties, which means it can help build muscle like steroids and, according to a study published in the British Journal of Sports Medicine, it can also boost sprint and strength performance.
Another orally ingested beta2-agonist known as clenbuterol aka clen packs an even bigger punch than albuterol. Athletes in several sports — cycling, swimming, baseball and soccer — have tested positive for clenbuterol use, although many have claimed that the drug could be traced to contaminated food.
While clenbuterol has historically been given to animals to produce leaner meat, the U. banned its use in meat in and the European Union followed suit in If the acronym sounds familiar, it probably is. GHB is known as a "date rape" drug because it can quickly render a user so relaxed and euphoric — especially when combined with alcohol — that they are easily taken advantage of.
Even scarier, it can cause amnesia, improving the chances that predators who slip the tasteless chemical into an unsuspecting imbiber's cocktail will get away with their misdeeds. Because of the risks it posed, the Drug Enforcement Administration DEA banned GHB in but then brought it back to the market two years later after it was found to be useful in treating narcolepsy.
Its use has since expanded to include another rare sleeping disorder, but GHB is only prescribed under strict safety controls. Even before it gained infamy as a date rape drug, GHB was thought to improve exercise performance and muscle mass.
There's even some scientific evidence that GHB increases growth hormone concentration. The drug apparently became popular among bodybuilders looking for alternatives to steroids in the s when the hormones were first being controlled. Mike Foxwho was a personal trainer and good friend to retired New York Mets' player Mike Piazza, shot himself while trying to give up GHB in Bodybuilder Mike Scarcella, who was Mr.
America and Mr. USA, died in August during a GHB withdrawal while hospitalized after a bar fight in Texas.

Hypothesis In the course of their career, athletes constantly set goals and make choices regarding the way these goals can be achieved. Testing the hypothesis Model-testing requires a series of carefully planned and coordinated studies. Implications A hypothesized life-cycle model of PE identifies vulnerability factors across the stages of athlete development with the view of informing the design of anti-doping assessment and intervention.
Background The amateur notions of the 'gentleman sport' have been surpassed by the need for effectiveness and efficiency in order to maintain the constant improvement of sports performance.
The hypothetical model The model we propose here can be characterised by i the combination of trait, systemic and situational factors, ii its developmental approach and iii the assumed outcome expectancy that led to functional use of PE substances by athletes.
Influencing factors Stages of the life cycle model of PE are affected by a host of vulnerability and inhibiting factors, which are categorised as: i individual differences and ii systemic factors Fig 1.
Figure 1. The major groups of vulnerability factors in doping. Full size image. Figure 2. Life cycle model of performance enhancement. Table 1 Vulnerability factors and potential individual and systemic remedies Full size table.
Testing the hypothesis Considering the complexity and reiterative nature of the model, empirical testing of the model as a whole is not feasible. Proposed Approach In order to set the parameters of the model, knowledge can be accumulated via a thorough literature search where scientific evidence is available for i drug efficacy, detectability and toxicity, ii comorbidity of drug and doping [ 91 — 94 ]; nutritional supplements and anabolic steroids or other doping [ 11 , 90 , 95 ], as well as iii relevant personality factors and their influence on behavioural outcomes [ 12 , 14 , 15 , 49 , 50 ].
Specifically, empirical research contributing to the model parameters could be conducted in one or a combination of the following areas: i Experimenting with and developing reliable methods for collecting information on or estimate the prevalence of doping behaviour i.
implicit assessment or estimation ; ii Identifying internal risk and protective factors; a. moral value and belief system, knowledge and health beliefs; iii. Identifying external risk and protective factors; a. environment effect e. socioeconomic variables, type of sport, motivational climate, etc.
influence of close others e. family, coach, peers, doctors, etc. Implications The current anti-doping policy has received much criticism for its elite focus, sanction-based approach and associated costs [ 53 , — ].

Carnitine transports long-chain fatty acids into the mitochondria. This allows them to be burned for energy, which can help boost exercise performance. Even so, many athletes continue to take the supplement.
Taking more than 3 grams of carnitine per day can cause side effects like nausea, vomiting, stomach cramping, and diarrhea. Carnitine can also interact harmfully with some medications, such as thyroid medications and the blood thinner warfarin.
Drugstores often sell the mineral as chromium picolinate. Muscles use creatine to release energy, which enhances lean muscle mass and increases muscle energy. Those who take creatine often do so as a means to build muscle mass.
Taking creatine is also not without its side effects. For example, creatine can cause weight gain, muscle cramping, and stomach cramping.
Additionally, the liver and kidneys must filter creatine. Taking an excessive amount can put a strain on these important organs, which could potentially damage them. Individual results may vary for all of these supplements. Talk with your doctor or athletic trainer about the safety and effectiveness of individual supplements.
The NCAA and the Olympics commission have banned some substances because they offer an unfair advantage or can cause harm to the athlete. Anabolic and other steroids are illegal in sporting events and according to the law.
The side effects are numerous and potentially fatal. Examples include androstenedione, stanozolol, axiron, and fortesta. DHEA is possibly the most abundant steroid in humans. Using synthetic versions to increase steroid production is potentially dangerous.
Diuretics are medications that cause a person to urinate more frequently. Diuretics can cause a variety of harmful side effects, such as cramping, dizziness, blood pressure drops, and electrolyte imbalances.
Blood doping is the process of boosting red blood cells to help carry more oxygen to the muscles and lungs. It can be done through a blood transfusion or through use of drugs like erythropoietin. Athletes use the medication to make more red blood cells in their bodies.
Endurance athletes may especially try to use erythropoietin, believing they they can perform longer with more oxygen. Ephedrine is a central nervous stimulant.
Ephedrine produces similar effects to adrenaline, but it too can be dangerous. It can cause serious cardiovascular effects, including stroke, and a whole host of other problems. Both athletic organizations and the FDA have banned it. HGH is a drug developed to help treat growth disorders in children.
It stimulates cell reproduction and regeneration. Athletes looking to gain an edge may misuse this drug to achieve it. Potential complications include enlarged organs and chronic disease. They can cause more damage than stripping an athlete of a title. Training, dedication, hydrating fluids, and proper diet are safer options and better than any ergogenic aids for boosting performance.
