Yelena Isinbayeva hopes the doping scandal affecting Russian athletes will not stop her competing in a fifth Olympic Games in Rio de Janeiro next year.
Russia were provisionally suspended by the IAAF last week amid allegations of state-sponsored doping following an independent commission established by the World Anti-Doping Agency.
The commission called for the All-Russia Athletic Federation to be banned over allegations of "corruption and bribery" at the highest levels of international athletics.
That suspension has cast doubt over Russian athletes competing in Brazil, although International Olympic Committee president Thomas Bach believes clean competitors will be able to participate.
And Isinbayeva - a two-time Olympic gold medallist in the pole vault - hopes that is the case as she prepares for her final appearance at the global showpiece.
"Of course I feel sad [that Russia could be banned], and of course everyone knows that the Olympic Games in Rio would be my last one and fifth," she said at a media event in Moscow.
"Of course I'd like to do my best there, because in London I missed first place [after claiming bronze] so I'd like to do something great in Rio.
"I'm really looking forward to that. If I don't have that opportunity then I will be really sad, and my retirement won't be as great as I imagined."
The 33-year-old hopes those involved in the scandal are caught, allowing the clean athletes to be in peak physical condition for the Games.
She added: "I hope the truth will come out. Everyone must be responsible for their mistakes.
"I'm not involved so me and other clean athletes must stay away from such a problem. We must continue our training, our preparation for the Olympics."
