It would appear that more professional athletes may be doping more than was initially believed.
A study supported by anonymous surveys was performed nearly six years ago. Finally seeing the light of day, the results indicate that the application of doping by professional athletes is substantially higher than initially believed.
As reported by The Guardian, “The research, based on anonymous surveys carried out at two elite athletics competitions in 2011, found that up to 57% of competitors admitted doping in the previous 12 months, a figure far surpassing the 1-2% identified by blood and urine tests carried out by the World Anti-Doping Agency (Wada), and higher even than the 14% prevalence estimated from the athlete biological passport.”
