Mariya Sergeyevna Savinova (Russian: Мария Сергеевна Савинова; born 13 August 1985) is a Russian former athlete who specialized in the 800 metres event. In 2017, she was found guilty of doping and was subsequently suspended from competition for four years. In addition to the ban, she had three years of elite results nullified and was stripped of both her World Championship medals (2011 and 2013) and her 2012 Olympic gold medal.
In December 2014, in an undercover documentary filmed by a Russian whistleblower which aired on German TV, Savinova admitted to injecting testosterone and using the anabolic steroid oxandrolone. She said, "Oxandrolone is very quickly out of my body again. It takes less than 20 days. We have tested that. My husband has very good contacts at the doping control laboratory."[3][4] The footage led to Savinova's blood samples being re-examined and launched an investigation by the World Anti-Doping Agency into Russia.[5]
On 10 February 2017, the Court of Arbitration for Sport issued a 43-page opinion[6] which noted that, “It follows from the information and intelligence provided by Ms. Yuliya Stepanova (Savinova's teammate) that the Athlete [Savinova] used prohibited substances over a long period of time." The CAS upheld the four-year ban for Savinova, nullified her results from July 2010 to August 2013, and stripped her of the medals she was awarded during that time, including prize money and appearance fees.[4][10]
