This means that an athlete can be sanctioned for an anti-doping rule violation even if they did not knowingly or intentionally use a prohibited substance. This principle places the burden of ensuring that no prohibited substances enter an athlete's body squarely on the athlete themselves. Athletes are therefore responsible for ensuring that they understand the anti-doping rules, that they use only authorized medications, and that they take precautions to avoid any accidental or unintentional doping violations.

The principle of strict liability is based on the idea that the use of prohibited substances or methods is inherently wrong and contrary to the spirit of fair play in sport. It also recognizes that doping can have negative effects on both the individual athlete and the wider sport community. 

It is important to note that there are some limited exceptions to the strict liability principle, such as when an athlete can demonstrate that they were inadvertently exposed to a prohibited substance through no fault of their own, or that the substance was present in a medication they were taking for a legitimate medical condition. However, in general, the strict liability principle places the responsibility for avoiding doping violations squarely on the athletes themselves.
