Middle distance runner Ekaterina Poistogova was one of two Russian athletes and two coaches banned by the Court for Arbitration for Sport for breaching anti-doping rules.
Poistogova, who won a bronze medal in the 800m at the 2012 London Olympics, was banned for two years on Friday for the use of a banned substance. The ban is backdated to August 2015, with her results from October 2014 nullified.
Alexei Melnikov, the former senior coach of the Russian national athletics team, and Vladimir Kazarin, a Russian athletics coach who trained short, middle and long-distance runners, both received life bans.
The Swiss-based court also handed an eight-year ban to race walker Stanislav Emelyanov for his second doping offence.
The CAS has been ruling on cases because the Russian Athletics Federation is suspended following the ongoing doping scandal.
