PARIS (AP) — A long-delayed study funded by the World Anti-Doping Agency says one third of athletes may have knowingly doped shortly before they competed at the 2011 Track World Championships – although few of them were caught at the time.
The peer-reviewed study, published in the journal Sports Medicine, estimated that doping was even more widespread at the Pan-Arab Games in 2011, with at least 45 percent of competitors thought to have doped in the 12 months before the regional multi-sports event.
The researchers said a total of 2,168 athletes at the two events participated in anonymous questionnaires upon which the study was based.
