A member of the IOC Athletes’ Commission says it is pushing for coaches and parents to be “punished more severely” when their athlete is convicted of doping. Former Olympic fencing champion Britta Heidemann spoke to Eurosport in the wake of 15-year-old Kamila Valieva’s positive test for trimetazidine, a banned heart drug. Ad/> Valieva was cleared to compete in the women’s singles by the Court of Arbitration for Sport (CAS) on Monday after her provisional suspension was lifted by the Russian Anti-Doping Agency (RUSADA).
