One of the biggest newspoints ahead of the Rio Olympic Games was the ban of the Russian athletic contingent. This was because of an organised state sponsored doping system in Russia, which allowed athletes the use of banned substances. While Russia was not altogether banned as a country, 118 athletes from their originally selected 389 missed out on Olympic participation. And in the ongoing Paralympics, Russia is banned in totality.The Russian story, many say, constitutes the biggest doping scandal ever and has resulted in a bitter power struggle in Olympic circles. While the Russian state maintains that it is being wronged and is being targeted, leading Olympic nations have supported the strong action taken against the Russians in the name of clean sport and in advocating zero tolerance against performance enhancement drugs.

(Also Read: Russia stripped of two Beijing Olympic medals for doping)Question is if this is an act of settling on scores from the Russian side? Why have the hackers revealed records of leading US athletes first? Is there a story behind the story? Is the cold war back in the sporting domain?While the Russian state has distanced itself from the hacking, suspicions will remain. And it will only add to the already brewing bitterness in Olympic circles over what is going on. The hacking also exposes the fragility of the WADA system and asks serious questions about the relevance and efficiency of the organization.advertisementMore importantly, it asks serious questions of US athletes like Biles. The quadruple gold winner has tweeted saying she has had the Attention Deficit Hyperactivity Disorder since childhood and has been on medicine for this problem for a long time. She has also said that she believes in clean sport and has not broken any rule. Biles, for the record, did obtain the necessary TUE (Therapeutic Use Exemptions) and is thus allowed the use of certain banned substances.However, did the world know about this problem before? Can the TUE be misused by athletes the world over? The US history over doping – the Balco scandal for example is enough to make the world suspicious. What were the mitigating circumstances that forced US authorities to give Biles the necessary permission? Has the case been reviewed ever and do these stimulants give her any added advantage over other athletes?These are uncomfortable questions that have cropped up in the backdrop of the hacking. While it is indeed despicable that confidential medical records are hacked, it is also true that sport should be above suspicion at every level. And the hacking has done exactly the opposite. It has ended up sowing the seeds of suspicion. Sad but true.As I said earlier, may be the cold war is back again and we have not seen the last of this doping scandal.
