No standarisation or harmonisation in anti-doping testing frequency.

The use of performance-enhancing drugs (PEDs) has undermined the credibility of sports for many years, with cycling and athletics, especially badly hit. The World Anti-Doping Agency has been tasked with leading the fight against the use of PEDs in sport and has been largely successful in achieving standardisation and harmonisation in terms of rules and regulations but has not addressed the question of testing frequency to any meaningful extent. This study, which focuses on athletics, shows vast differences in testing rates around the world with some of the most successful countries in athletics doing very little testing compared to many other countries.
