Flávia Oliveira

In June 2009, in her first year as a professional, Oliveira tested positive for oxilofrine, an illegal stimulant, while racing with the Italian professional team SC Michela Fanini at the Giro del Trentino Donne.[7] The adverse finding came from a supplement purchased in the United States that did not include oxilofine on the ingredients label. In fact, several supplement companies were making products that contained oxilofrine without indicating the substance on the label. [8] Oliveira later sued the supplement manufacturer.[9] 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.[10] This would see her resume competition on 1 March 2011.

A second positive occurred nine years later on 26 June 2018 at the Brazilian Road Championships.[11] 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.[12] Oliveira returned to racing shortly after, recording her best ever finish in a World Cup Event at GP Plouay, where she finished 8th.[13]

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.[14] Additionally, WADA made the determination that vilanterol is not performance enhancing and removed it from the 2021 prohibited list when used as Oliveira did.[15]

While preparing for the 2020 Olympics, Oliveira was struck by a car and suffered a broken pelvis.[16] After rehabilitation, Oliveira collected enough Olympic qualification points to provisionally qualify her for the 2020 Tokyo Olympics.[17] However, three weeks before the World Championships in Yorkshire, England,[18] Oliveira suffered a crash that effectively ended her season in the GP Fourmies in France.[19]
