She is currently serving a four-year suspension from 2021 to 2025 for anti-doping rule violations. Her results from 15 July 2012 onwards had been disqualified, including her 2012 Olympic gold medal in the 400 metres hurdles.
According to World Athletics, prior to her ban, Antyukh had last competed in 2016, aged 35. She was 40 years old at the outset of the ban, and will be 44 years old when it concludes.

2012: Olympic champion at 31 years old
On 8 August 2012, Antyukh, then 31 years old, won the gold medal in the 400 metres hurdles at the 2012 Olympic Games in London, with a personal best time of 52.70 seconds.[9][10][11][12] Three days later, she won the silver medal for the 4×400 m relay, helping finish in a time of 3 minutes, 20.23 seconds.[13] She received the Russian Order of Honour after the Olympics for her performances.[14]
2016: Teammate disqualified, stripped of her 2012 Olympic silver medal
In 2016, Antyukh's silver medal in the 4×400 m relay from the 2012 Olympic Games was stripped, with medals reallocated to relay teams from Jamaica (silver) and Ukraine (bronze), after teammate Antonina Krivoshapka had her results from the event disqualified.[15] In 2019, all Russians, including Antyukh, were banned by the World Anti-Doping Agency from competing in international track and field events representing Russia for a four year period.[16]
2020–2025: Disqualified, stripped of her 2012 Olympic gold medal
In 2020, Antyukh was among four Russian track and field athletes charged with doping offences, facing charges of using a prohibited substance or method. The Athletics Integrity Unit said the cases were based on an investigation into Russian doping for the World Anti-Doping Agency presented in 2016 by Canadian lawyer Richard McLaren.[17] Her ban was confirmed on 7 April 2021 by the Court of Arbitration for Sport when she was suspended from athletics for four years, to 2025, with all her results from 30 June 2013 onwards disqualified.[18][19] In October 2022, more than 10 years and 2 months after the race, her results from July 2012 to June 2013 were disqualified, stripping her of the gold medal in the 400 m hurdles at the 2012 Summer Olympics, with the new recipient being the former silver medalist, American Lashinda Demus.[20][21][22][23]
The stripping of her gold medal marked the attainment of stripping all Russians who won a gold medal in track at the 2012 Summer Olympics of their gold medal(s).[19]
In addition to being banned for anti-doping rule violations, Antyukh, along with all other Russian and Belarusian athletes, was subjected to another ban starting 1 March 2022, which excluded her from all World Athletics competitions with no communicated end date and was implemented in response to the 2022 Russian invasion of Ukraine, part of the ongoing Russo-Ukrainian War that began in 2014.[24]
