Nadezhda Sergeeva, pilot of the two-woman bobsled team representing the Olympic Athletes from Russia, proudly proclaimed her anti-doping stance when she appeared in a YouTube video wearing a sweatshirt with the slogan “I don’t do doping” stamped brightly across the front. But that slogan isn’t ringing so true today, after Russian Bobsled Federation president Alexander Zubkov announced that Sergeeva had tested positive for a banned heart medication, apparently the stimulant trimetazidine, in a drug test.
