The news was confirmed at the federation. Her post will be taken over by vice-presidents Andris Smočs and Jānis Upenieks.
Meanwhile Radeviča said that her sole task during her work at the federation has been strengthening, developing and popularizing athletics in Latvia.
"Taking into account the present situation, I have decided to step down as president of the Latvian Athletics Federation so that the started projects are finished and the federation is not put to risk. I have dedicated my entire life to athletics and I care about the future of this sports in Latvia, as well as the further development of the Latvian Athletics Federation in cooperation with European and global athletics organizations," she said.
Radeviča nevertheless insisted that she has not consumed doping wittingly, but did not go as far as to contradict the results of the test.
Radeviča placed fourth at the London games and is one of the best-known athletes in the country.
Since 2017 she has also served as the president of the Latvian Athletics Federation.
Radeviča has tested positive for oxandrolone, an anabolic steroid and has since been hit with an interim ban.
She retired from professional sports in 2012, after narrowly missing out on a medal in London.
She currently holds the Latvian women's long-jump record.
