Paula Radcliffe is sceptical whether Russia has done enough to clean up its drug-testing programme in time for the Olympics.
The marathon world record holder has also questioned if Russian athletes would know how to "train without cheating" if allowed back for the Rio Games in August.
The Russian track and field federation was suspended in November after an independent report by a World Anti-Doping Agency panel alleged systematic corruption and doping cover-ups in Russia.
The WADA investigation followed allegations made in a documentary by German broadcaster ARD.
The IAAF has laid down a series of criteria for Russia to meet before they can be eligible for re-admission. The international governing body, headed by Sebastian Coe, is scheduled to hold a news conference on Friday after a two-day meeting of its ruling council.
ARD aired another documentary Sunday, in which a Russian coach was accused of continuing to train athletes while he serves an IAAF suspension.
The programme alleged another coach offered banned substances for sale and that the acting head of the Russian anti-doping agency had allowed an unidentified athlete to reschedule a supposedly no-notice drug test.
Radcliffe spoke of her shock at watching ARD's "very damaging" revelations.
The 42-year-old, who retired in April 2015, said: "It doesn't seem a lot has changed. So if the decision was being made now, based on that and I'm not privy to whatever information the IAAF have then I would say no, not enough has been done.
"I think everybody had some suspicions but not that it was on that scale, and so supported by the state, and so much the norm.
"If they are allowed back in and they do come back in clean, I doubt whether there'll be that much performance there because I doubt whether they actually know how to train without cheating.
"It's a tough job to move it forward and get the changes through. If the sport all pulls together and actually tries to proactively do something in the right direction, we're going to get a lot further than if we all sit here and go 'It's terrible. What a mess. We don't want Coe in there.'"
Radcliffe, a three-time winner of the New York and London marathons, is a member of the IAAF's athletes commission.
On Thursday, she threw her support behind a drive to get Russia's track federation to refund all prize money and appearance fees of athletes whose results have been nullified for doping offenses since 2009.
"They should have to repay what they've essentially stolen so it can be redistributed to the athletes who should have won it," Radcliffe added.
Radcliffe felt she was implicated during a British Parliamentary hearing last August into allegations levelled by British and German media of rampant blood doping in endurance events. She was cleared of any wrongdoing.
On comparisons with the case of Maria Sharapova, who admitted to failing a drugs test on Monday, Radcliffe said: "I hadn't actually done anything wrong. But she's failed a test.
"It's not about bitterness, but it should be equal and fair across the board across all sports."
