What is an « anti-doping rule violation » ?
"Doping" is what happens when a violation of the anti-doping rules has taken place. The WADA Code and FEI Anti-Doping Rules for Human Athletes list 11 categories of anti-doping rule violations. The typical violation is a positive test, but not all violations are about taking prohibited substances.
Also, athletes are not the only ones involved in sport who can commit anti-doping rule violations. Some violations can be committed by non-athletes: members of an athlete’s entourage (coaches, medical staff, parents, officials, any other member of an athlete’s entourage) or any other person involved in equestrian sport.
