Published on August 26, 2019, a report by the University of Lausanne revealed that 18% of endurance athletes exhibited signs of blood doping at the 2011 and 2013 world championships.
The study, which analyzed blood samples from 1,222 athletes participating in endurance events in Daegu (2011) and Moscow (2013), found a higher prevalence of blood doping among female athletes (22%) compared to male athletes (15%).
Despite the introduction of the athlete biological passport by the IAAF in 2011, the report found that blood doping rates remained relatively unchanged in 2013.
However, the report's authors emphasized the importance of continued development and monitoring of the Athlete Biological Passport as a means to combat blood doping.
"Our results from robust haematological parameters indicate an estimation of an overall blood doping prevalence of 18% in average in endurance athletes," the report stated.
