Doping urine test

Doping urine test is a supplementary test method used to check whether athletes are taking doping. The reason is that metabolites in the human body are generally excreted through the urine. In addition, urine sampling is harmless to the human body, and athletes are willing to accept it. It is a simple and effective test method. The earliest doping urine tests were performed during the game, that is, during the game. Later, in order to avoid doping tests, some athletes used stimulants during normal training and stopped before the game. This is because drugs such as anabolic agents and peptide hormones can promote athletes to increase muscle size and other physiological effects, and can maintain these effects for a long time after stopping the drug. In order to prevent athletes from using stimulants in this way, since the 1990s, the international sports community has added extra-urine urine tests in addition to the stadium urine tests. That is, without prior notice, during the normal training time of the athlete, the selected object is suddenly checked at any time. This kind of inspection is always carried out by relevant officials of the Olympic Games to fly around the world, so it is often referred to as flight inspection, commonly known as "flight inspection". Through this examination, the corresponding symptoms can be judged.
