Geneva • Evidence that Russia ran a state-backed doping scheme for several years has been used to prove new cases of cheating by track and field Olympic and world champions.
Ivan Ukhov, the 2012 Olympic high jump champion was among 12 Russian track and field athletes found guilty Friday of taking part in "systemic doping," the Court of Arbitration for Sport said.
Ukhov was disqualified from the 2012 London Games, while hammer thrower Tatyana Lysenko and high jumper Svetlana Shkolina also have been disqualified after winning gold at the 2013 world championships in Moscow.
