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.

反掺杂测试频率无标准化或协调统一

多年来，使用性能增强药物（PED）损害了体育运动的信誉，尤其是在骑自行车和田径运动中，受到严重打击。世界反兴奋剂机构的任务是领导在体育运动中使用PED的斗争，并在规则和法规方面实现了标准化和统一方面取得了很大的成功，但并未在任何有意义的程度上解决测试频率的问题。这项针对体育运动的研究表明，与其他许多国家/地区相比，世界上一些最成功的体育运动国家/地区很少进行测试，因此全球的测试率存在巨大差异。
