The ARAF are currently suspended after the International Association of Athletics Federations (IAAF), headed by Coe, imposed a ban after allegations of state-supported doping following an investigation by the World Anti-Doping Agency (WADA).

The two-time Olympic pole vault champion and world record holder has been the most vocal critic of the IAAF decision and has now challenged Coe on her Instagram account to explain the decision to prevent her from competing at Rio 2016.

The only athlete allowed to represent Russia at Rio 2016 will be long jumper Daria Klishin, who the IAAF have ruled can compete because she has lived in the United States for three years. 

"There has not been any answer to the direct question to IAAF President Coe -  why and for what reason Isinbaeva (sic) is disqualified from participation in Rio," she wrote. 

"He just leaves ignoring the question. 

"There is still no clarity, no answers, I still don't give up trainings (sic) hoping that this injustice is to end very soon. 

"Friends, I thank you for your support and petitions; dear mass media, thank you but I ask you one more time, probably for the last time to help me get to the truth and find out from Coe the reason for my disqualification, exactly my disqualification. 

"And let him not say that I am part of the Russian Athletics Federation and have to be responsible for other athletes' mistakes because Daria is also part of it but she only lives in a different country and doesn't carry any responsibility for other sportsmen! 

"I do not want to give up and simply to accept such an unfair and vile IAAF decision concerning myself! 

"If there is at least one chance to perform in Rio, I want to use it."

Isinbayeva had supported Coe during his successful campaign last August to replace Lamine Diack as President of the IAAF.

She is now herself increasingly turning her attention to sports administration and may put her name forward as a potential candidate for the Presidency of the ARAF.

The position is currently held by Dmitry Shlyakhtin, elected in January on a temporary basis to replace Vadim Zelichenok.

He himself had taken over in an interim basis on February 2015 after Valentin Balakhnichev stepped down when the reports of wrongdoing first emerged via German broadcaster ARD.

Russian Sports Minister Vitaly Mutko has revealed that an election to find a permanent replacement for Balakhnichev is due to take place next month.

"It is certainly still early to speak about such an issue as me in charge of ARAF," Isinbayeva told Russia's official news agency TASS.

"However, I do think about running for the post."

Isinbayeva is also currently standing for election to the International Olympic Committee (IOC) Athletes' Commission. 

The 34-year-old from Volgograd is still allowed to stand, even though she is not able to compete here because of the IAAF's ban.

The IOC, who have permitted her to take part in the election, despite missing the deadline for nominations by a month, confirmed today that if she wanted to come to Rio 2016 she would be given accreditation for the Games and allowed to stay in the Olympic Village so she can campaign.
