The International Gymnastics Federation imposed the ban after both tested positive for furosemide -- a diuretic sometimes used by athletes to shed weight quickly or to mask other forbidden products. The suspension was backdated to the date of the positive test -- the Goodwill Games in Brisbane, Australia, in August 2001.
The federation ordered the pair to return the medals they won at the rhythmic gymnastics World Championships, held in Madrid, Spain, in October. Kabayeva, 18, was overall world champion while 19-year-old Tchachina took the silver, and between them the pair won gold and silver in every event.
FIG announced last month that Tchachina tested positive again for furosemide during the world championships.
The Russian rhythmic gymnastics federation will file an appeal, a federation official said Thursday.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.

Remind me later.
