Sedov represented Kazakhstan at the 2008 Summer Olympics in Beijing, where he competed for the men's light heavyweight class (85 kg). During the competition, he successfully lifted 180 kg in the single-motion snatch, and hoisted 200 kg in the two-part, shoulder-to-overhead clean and jerk, for a total of 380 kg. Sedov, however, narrowly lost the Olympic medal to Armenia's Tigran Vardan Martirosyan by three kilograms short of his record from the clean and jerk, finishing the entire event in fourth place. On 17 November 2016 the IOC disqualified him from the 2008 Olympic Games and struck his results from the record for failing a drugs test in a re-analysis of his doping sample from 2008.
Sedov served a two-year ban for doping from 2006. The sanction ended 18 May 2008. In 2016 he was disqualified from the 2008 Olympic Games for failing a doping re-test.
