Doping is the use of any substances of natural or synthetic origin in sports, which make it possible to improve athletic performance as a result of their intake. Such substances can dramatically increase the activity of the nervous and endocrine systems and muscle strength for a short time, they also include drugs that stimulate the synthesis of muscle proteins after exposure to muscle loads. A huge number of medicines have the status of prohibited for athletes during competitions. The modern concept in the field of combating doping in top—level sports is given in the WADA Anti-Doping Code (the World Anti-Doping Agency, established on the initiative of the International Olympic Committee - the IOC). Every year, WADA publishes a list of banned drugs for athletes and new versions of the so-called standards: the international standard for laboratories, the international standard for testing and the international standard for registration of therapeutic exemptions.

Today it is considered that doping is a conscious intake of a substance that is excessive for a normal functioning athlete's body, or an excessive dose of medication, with the sole purpose of artificially enhancing physical activity and endurance during sports competitions.

The fight against doping is also underway because records are given at the cost of the health and life of athletes.
