The Athletics Integrity Unit (AIU) has banned Natalya Antyukh of Russia for the use of a Prohibited Substance/Method which is a breach of the World Athletics Anti-Doping Rules.
The 41 year-old was stripped of her 2012 Olympic silver medal in the 4×400 relay by the IOC in 2017 because the Russian team was disqualified after doping was found in the samples of runner Antonina Krivoshapka.
In April 2021, the Court of Arbitration for Sport (CAS) disqualified Antyukh for four years for anti-doping rule violations. The period of the athlete’s suspension is counted from April 7, 2021. The results has been disqualified from June 30, 2013.
Last year, Antyukh was banned four years in a doping case related to evidence from the 2016 McLaren report on Russian doping. Her results from July 2013 through December 2015 were also stripped. She last competed in 2016, according to World Athletics. In the 2012 Olympic 400m hurdles final, Antyukh, then 31, lowered her personal best by 22 hundredths of a second to hold off Lashinda Demus by seven hundredths for the gold medal.
Following AIU charges based on LIMS data, Russian athlete Natalia Antyukh has been banned for the use of a Prohibited Substance/Method. DQ results from 15 July 2012 until 29 June 2013.
