Definition[ edit ] The classifications of substances as performance-enhancing substances are not entirely clear-cut and objective. As in other types of categorizationcertain prototype performance enhancers are universally classified as such like anabolic steroidswhereas other substances like vitamins and protein supplements are virtually never classified as performance enhancers despite their effects on performance. As is usual with categorization, there are borderline cases; caffeinefor example, is considered a performance enhancer by some but not others.
History[ edit ] The use of drugs in sports goes back centuries, about all the way back to the very invention of the concept of sports.
For instance, Scandinavian mythology says Berserkers could drink a mixture called "butotens", to greatly increase their physical power at the risk of insanity. One theory is that the mixture was prepared from the Amanita muscaria mushroom, though this has been disputed.
The ancient Olympics in Greece have been alleged to have had forms of doping. In ancient Romewhere chariot racing had become a huge part of their culture, athletes drank herbal infusions to strengthen them before chariot races.
The Illustrated London News chided: It may be an advantage to know that a man can travel miles in hours, and manage to live through a week with an infinitesimal amount of rest, though we fail to perceive that anyone could possibly be placed in a position where his ability in this respect would be of any use to him [and] what is to be gained by a constant repetition of the fact.
And the more spectators paid at the gate, the higher the prizes could be and the greater was the incentive of riders to stay awake—or be kept awake—to ride the greatest distance.

Research and limited tests have been conducted only to find short-term, reversible effects on athletes that are both physical and mental. These side effects would be alleviated if athletes were allowed the use of controlled substances under proper medical supervision. These side-effects include Intramuscular abscesses and other microbial bacteria that can cause infections, from counterfeited products the user decides to purchase on the black market, high blood pressure and cholesterol, as well as infertility, and dermatological conditions like severe acne.
Mental effects include increased aggression and depression, and in rare cases suicide has been seen as well. Long-term effects have not been able to be pinpointed just yet due to the recency of testing these substances but would start show up as early steroid users reach the age of 50 and older.
These "de facto experiments investigating the physiology of stress as well as the substances that might alleviate exhaustion" were not unknown outside cycling. He crossed the line behind a fellow American Fred Lorzwho had been transported for 11 miles of the course by his trainer, leading to his disqualification.
