The Russian track and field federation says it will investigate new doping-related allegations against Russian coaches.
A documentary transmitted on March 6 by German broadcaster ARD accused Russian coach Vladimir Mokhnev of continuing to train athletes while suspended by the international athletics association (IAAF) and said another coach offered banned substances for sale.
The Russian athletics federation said in a statement on March 7 that the allegations would be investigated and that "we will not allow individual people to cast a shadow over Russian athletics."
On March 6, the IAAF said its Russia taskforce would investigate the ARD allegations.
The ARD documentary also alleged that the acting head of the Russian anti-doping agency, RUSADA, had allowed an unidentified athlete to reschedule a supposedly no-notice drug test.
RUSADA did not respond to a request for comment.
