Russia's Olympic Committee pressed on Thursday with its preparations for the Rio Olympic Games despite the threat of a ban for state-run doping hanging over the country.

At a regular meeting in Moscow the executive board approved a 387-strong team to compete at this summer's games starting on August 5.

The team's line-up includes the 68 track and field athletes, whose fate hinges on the Court of Arbitration for Sport (CAS) in Lausanne, which will rule Thursday on whether the IAAF had grounds to impose a blanket ban on Russia's athletics federation.

"The (Olympic) squad's line-up has been formed according to the applications of the country's sports federations," the committee chief Alexander Zhukov told the press.

The Olympic Committee released a statement on their website saying that 387 competitors were included in the list.
