Flávia Oliveira

In 2020, the prescribed use of vilanterol to treat an acute condition caused an adverse finding for Oliveira. Oliveira established she had no significant fault or negligence with respect to the violation. USADA granted a TUE to Oliveira for the medication after the fact. Additionally, WADA made the determination that vilanterol is not performance enhancing and removed it from the 2021 prohibited list when used as Oliveira did.

While preparing for the 2020 Summer Olympics, Oliveira was struck by a car and suffered a broken pelvis. After rehabilitation, Oliveira collected enough Olympic qualification points to provisionally qualify her for the 2020 Tokyo Olympics. However, three weeks before the 2019 Road World Championships, Oliveira suffered a crash in the GP Fourmies in France that effectively ended her season.

A second positive occurred nine years later on 26 June 2018 at the Brazilian Road Championships. Oliveira won the race and was allowed to maintain the title of champion of Brasil after the hearing. In a unanimous decision, the arbitration panel ruled that Oliveira did not ingest the contaminant intentionally and in fact, the contaminant entered her system after the race had completed. Oliveira returned to racing shortly after, recording her best ever finish in a World Cup Event at GP Plouay, where she finished 8th.

Oliveira is a past winner of the mountains classification at the Giro d'Italia Femminile in 2015, the Brazilian National Road Race Championships, and she was the winner of the general and mountain classifications at the 2016 Tour Cycliste Féminin International de l'Ardèche.

In June 2009, in her first year as a professional, Oliveira tested positive for oxilofrine, a stimulant, while racing with the Italian professional team SC Michela Fanini at the Giro del Trentino Donne. The adverse finding came from a supplement purchased in the United States that did not include oxilofrine on the ingredients label. In fact, several supplement companies were making products that contained oxilofrine without indicating the substance on the label. Oliveira later sued the supplement manufacturer. In December 2009 the ban was reduced through an appeal to CAS after the panel found that she had not intentionally ingested the banned substance and there was no way that she could have known that the supplement would have contained a banned substance. This would see her resume competition on 1 March 2011.
