Samples from high-profile events, such as the Olympic Gamesare now retested up to eight years later to take advantage of new techniques for detecting banned substances.

Performance-enhancing drug testing -

These include stroke, heart attack and blocked arteries in the lung. Diuretics are drugs that change the body's balance of fluids and salts. They can cause the body to lose water, which can lower an athlete's weight. Diuretics also may help athletes pass drug tests that check for signs of drugs in the urine.

They dilute the urine and may hide traces of drugs. Diuretics can cause side effects when you take them at any dose — even at doses that health care providers suggest.

These drugs make athletes more likely to have side effects such as:. Nutrients are vitamins and minerals in foods that are good for you.

Some people try to get more nutrients from products called supplements. Supplements are sold in stores and online as powders or pills. One supplement that's popular with athletes is called creatine monohydrate.

The body makes its own creatine too. It helps muscles release energy. Creatine supplements may help athletes gain small, short-term bursts of power. Creatine seems to help muscles make more of an energy source called adenosine triphosphate ATP.

ATP stores and moves energy in the body's cells. It's used for activity that involves quick bursts of movement, such as weightlifting or sprinting.

But there's no proof that creatine helps you do better at sports that make you breathe at a higher rate and raise your heart rate, called aerobic sports. Some athletes try to gain weight so they can get bigger in size.

Creatine may help you put on weight over time. But that might be due to the extra water that creatine causes the body to hold on to. Water is drawn into muscle tissue, away from other parts of the body. That puts you at risk of getting dehydrated.

Studies show that it's safe for healthy adults to use creatine for a short or long time. It's important to use the doses that creatine makers suggest on the package. Stimulants boost the levels of some chemicals in the brain. They also make the heart beat faster and raise blood pressure.

Common stimulants include caffeine and drugs called amphetamines. Cold medicines often have a stimulant in them. Energy drinks are popular among many athletes. They often have high doses of caffeine and other stimulants.

The street drugs cocaine and methamphetamine also are stimulants. Some athletes may seem to get an edge from performance-enhancing drugs. But doping can have bad effects on health. In general, the long-term effects of performance-enhancing drugs haven't been studied enough.

And any short-term perks come with risks. Doping is banned by most sports leagues and groups too. There is a problem with information submitted for this request.

Part of the impetus for such a vast net is the proliferation of prohibited substances use across multiple sports. Anthony Butch, director of the official WADA lab located at UCLA. To illustrate the challenges of detecting one of so many illicit substances, Butch described the path of one subject's urine sample through his lab.

In this example, he explained the processes involved in testing for testosterone and some 60 similar substances classified under anabolic agents on WADA's prohibited list.

The complex procedure for one athlete's urine sample--from receiving, signing, unsealing, separating, testing and diagnosis--starts with the mail. To begin, there is the knock on the door from the delivery service, he said, signaling samples have arrived.

Here begins the "chain of command," a sign-in process to document each stage in handling the vials. A laboratory employee signs for the package, another must sign when the seal is broken, and so on throughout every step.

This is key because allegations of improper handling can affect the outcome of an athlete's appeal. The science is pretty hard to argue.

After the urine samples are taken and logged, they are portioned into "aliquots," or, "little vials--about 20 for each A and B sample," said Butch.

These 20 or so aliquots provide the amount needed for the many sub-categories such as the plus anabolic agents of the prohibited substances to be detected. Aliquots are kept in a lock-and-key refrigerator until ready for centrifuge. If it's purple, that's not urine. If the pH level is too close to 1.

Following this are the gas and liquid chromatography phases, where individual compounds may be detected. This is a process of separating aliquots into their different components by exposing them to increasing gradients of high heat.

First, Butch and his team pass small amounts of urine through a straw. The reason to use both gas and liquid chromatography in anabolic screening is because each of the more than 60 possible agents in that sub-category alone reacts uniquely to heat.

In either gas or liquid state, the residues are placed in ultra-thin chambers with internal diameters of 0. At each level, a different compound will stick, then release.

For Dr. Butch, that's a standard urinalysis that he and his team can accurately complete within 48 hours. Accuracy is paramount, as testing stakes are incredibly high for athletes. One positive test could cause them to lose their Olympic eligibility, their medals, or face a suspension or ban from the sport.

Butch, "You miss one 'Games' and you could be done. Such precise testing is done in a place designed for such exacting work. Butch's officially certified WADA facility occupies 20, square feet just off the UCLA campus and employs 50 full-time medical professionals. In fact, it is the largest WADA-accredited PED lab on the globe.

The United States is one of only three countries to feature two licensed centers. The others are Germany and Portugal. That second-busiest processing facility for PED testing is in Salt Lake City, Utah. Daniel Eichner, a self-described friend of and collaborator with Butch, has run the Salt Lake facility for more than a year, having worked previously for both the Australian and U.

Anti-Doping Agencies. Eichner said the importance to WADA of operating the second lab in the U. is for redundancy, "in the case the L. lab couldn't operate," he said. Often, that lab must work on tight deadlines, such as during competition, Butch said.

Now that the summer Prrformance-enhancing in London Appetite control goals come to a Body composition measurement, most assume performance-enhancing drug "PED" testing Performance-enhancing drug testing as well. Dru, PED laboratories test year round--during competition and off-season Appetite control goals multiple technologies to keep athletes in check and sports testjng free. To this end, Perfformance-enhancing are done routinely during the year to establish a baseline level for each subject, and to guarantee that all potential Olympians are tested at least once before competition. Inthe last year for which there is officially published data, WADA--the World Anti-Doping Agency--executed testing onurine and blood serum samples taken from athletes in Olympic sports alone compared to 77, in non-Olympic sports. Peak sampling occurred inan Olympic year, withindividual tests. To handle that volume, WADA has accredited 35 established testing labs spread among 32 countries worldwide.
