Swimming Australia says it’s “making inquiries” after bombshell reports about 23 Chinese swimmers – two-thirds of the country’s Olympic team – testing positive to the banned drug trimetazidine. The kicker is that they tested positive before going on to win 6 medals (including 3 gold) at the Tokyo Olympics. The World Anti-Doping Agency (WADA) confirmed it cleared the swimmers to compete after accepting their explanation about being exposed to the drug accidentally after it was detected in a hotel that they’d stayed in. As you might guess, that’s raised questions, but WADA’s medical director Olivier Rabin says the organisation stands by its decision – and it’s been backed up by World Aquatics. “Ultimately, we concluded that there was no concrete basis to challenge the asserted contamination”, Rabin said. But Swimming Australia says it advocates “for fairness and integrity”, and wants “to ensure a level playing field” ahead of the Paris Olympics.
