What is Doping in Sport
Definitions of Doping
Doping is defined as the presence of prohibited substances or methods to unfairly improve sporting performance and to gain an advantage over competitors
The International Olympic Committee (IOC) states that doping is the use of any method or substance that might harm the athlete, in a quest to gain an unfair advantage over their fellow competitors.
The World Anti-Doping Agency (WADA) defines that doping is the occurrence of one or more of the anti-doping rule violation set forth in Article 2.1 through 2.11 of the WADA Code.
