The president of the All-Russia Athletic Federation promised on Monday to take tough measures against coaches accused of doping athletes, and the athletes who work with them.
Dmitry Shlyakhtin said he and Sports Minister Pavel Kolobkov discussed the issue on Monday with a taskforce from the IAAF.
That follows allegations a suspended coach is continuing to work with a runner from the Olympic team, and that other Russian coaches are involved in providing banned substances to top Russian runners.
Shlyakhtin said serious investigations were underway.
"Today the minister and I discussed this issue with the taskforce and very tough measures will be taken in the near future on all these things which were covered," he said.
