A British newspaper has claimed that around a third of the world's top athletes at a major event cheated by using drugs. A study carried out at the World Athletics Championships in Daegu, South Korea in 2011 showed that 29-34 per cent of the athletes used performance-enhancing drugs in the previous 12 months. Reporters say that the International Association of Athletics Federations (IAAF) knew about the report but blocked its publication. The IAAF said there were many things wrong with the report. It is in discussions to help publish it.
The report is a huge shock to the athletics world. The newspaper said that a third of the medal winners in endurance races at the Olympics and World Championships had very unusual blood readings. The World Anti-Doping Agency (WADA) said it would investigate the claims in the report. An independent commission has already started work on this. The lead author of the report said that he and his colleagues were told not to discuss their research or the report. He said he thought that the IAAF and WADA "just blocked the whole thing".
