The head of the International Association of Athletics Federations (IAAF), the world’s top governing body for athletics, vigorously defended its anti-doping record on Monday, as global sporting bodies called for a thorough probe of the latest allegations to plunge international sports into crisis.
Britain's Sunday Times newspaper and Germany's ARD/WDR broadcaster reported on Sunday they had obtained secret data from the IAAF, supplied by a whistleblower, indicating suspicions of widespread blood doping in athletics.
"There are allegations made, no evidence. We want to look into them seriously because to say that in athletics between 2001 and 2012 we did not do a serious job with tests is laughable," IAAF president Lamine Diack told Reuters in response to the reports.
Diack said he “laughed when I read between 2001 and 2012 IAAF did not do the work," he added. The head of the IOC's medical commission had worked hard to combat doping in that period, Diack said.
Coming only weeks before the start of track and field's showpiece world championships event in Beijing on Aug. 22, the reports claim endurance runners suspected of doping had been winning a third of the medals at Olympic Games and world championships in that period.
The reports did not say that any athletes had failed doping tests, only that the tests had been abnormal, which can sometimes be a sign of cheating.
The allegations are the latest setback to tarnish the multi-billion dollar world of sports. Allegations of corruption in soccer's global governing body, FIFA, led to indictments against several current and former officials earlier this year.
International Olympic Committee (IOC) President Thomas Bach told reporters on Monday he had spoken to the head of the World Anti-Doping Agency and had full confidence in that body to investigate the claims thoroughly. "I don't know about the detailed allegations, which athletes, which competitions are affected," he said.
The World Anti-Doping Agency has said it was "very disturbed" by the reports.
Bach said the IOC would act with "zero tolerance" if there should be a case involving results at an Olympic Games. "But at this time we have nothing more than allegations and we have to respect the presumption of innocence for the athletes," he said.
Medals won could be affected if any cases of doping were subsequently unearthed using newer testing techniques that did not exist at the time.
The reports come weeks before a new IAAF president will be elected, with Britain's Sebastian Coe and Sergey Bubka of Ukraine bidding to replace Diack, who is retiring.
Sheikh Ahmad Al-Fahad Al-Sabah, the head of the Olympic Council of Asia and the Association of National Olympic Committees, appeared skeptical about the timing of the allegations. "If there is some mess, I hope it will be solved by the mechanism of the governance and anti-doping,” he said. “If not, related to election time, I will understand it."
Earlier, U.S. anti-doping agency chief executive Travis Tygart said an "aggressive review" was needed to protect clean athletes. "This is more evidence of what many of us already suspected," Tygart told Reuters.
The IAAF noted that the reports were based on confidential information obtained without permission.
A heavy preponderance of the "abnormal" results were from Russian athletes, according to the media reports. Russian sports minister Vitaly Mutko has said the allegations had nothing to do with Russia and that they reflected a power battle before the IAAF leadership vote.
In the report, Australian doping expert Robin Parisotto and another scientist, Michael Ashendon, said more than 800 athletes had recorded one or more "abnormal" results, defined as a result that had less than one chance in 100 of being natural.
Such athletes accounted for 146 medals at top events, including 55 golds, the Sunday Times said.
"There were 800-odd abnormal or suspicious results but not all of those would have been truly indicative of doping," Parisotto told Reuters.
Factors such as the timing of tests, altitude and testing conditions could have led to some suspicious results. Blood tests were not used as an official sanctioning tool until 2009, but the leaked data still showed a high number of suspicious or abnormal test results subsequently, he said.
Russia accounted for 415 abnormal tests, followed distantly by Ukraine, Morocco, Spain, Kenya, Turkey and others.
The allegations concern techniques to improve the ability of blood to carry oxygen, which can give an advantage in endurance events like cycling or running over medium and long distances.
The Sunday Times and ARD said they were given access to the results of more than 12,000 tests of more than 5,000 athletes taken between 2001 and 2012.
