The word doping is probably from the Dutch word dop, the nam

The word doping is probably from the Dutch word dop, the name of an alcoholic drinks make of grape skins used by Zulu soldiers in order to encourage their bravery in battle. The term became current around the turn of the 20 ^th century, originally referring to illegal drugging of racehorses. In 1928 the International Amateur Athletic Federation (IAAF) became the first to ban the use of doping. A reliable test method was finally introduced in 1974.
The practice of enhancing athletes’ performance through foreign substance or other artificial means, however, is as old as competitive sport itself. The most famous doping case of the 1980s concerned Ben Johnson, the 100-meter champion who tested positive for stanozolol(司坦咗醇) at the Olympic Games in Seoul, 1988.
The main front in the anti-doping war has rapidly shifted to blood doping since 1970s. Blood doping is the practice of adding red blood cells to the bloodstream in order to improve athletes’ performance. The blood is usually processed in order to create a concentration of red blood cells, and then freeze them until needed for transfusion(输血) back into the athlete shortly before the event. The extra red blood cells will deliver more oxygen and other essential elements to the athlete’s muscle tissues.
Just like any other problem, the only way to solve it is through education. Many high school sports programs now have people come in to talk to them about out the dangers of performance-enhancing drugs. Young players must be fully clear on the rules and what substances are banned. The NCAA (National Collegiate Athletic Association) has an easily accessible list of what substances are banned, how they are tested for and why they are banned on its website. This way, young players are clear on what they can put in their bodies. This is also a good way to educate players on the danger of the substances they may be tempted to use.
