Pavel Kulizhnikov

Kulizhnikov entered the 2020 World Single Distances Championships, taking place at Utah Olympic Oval in Salt Lake City. During the team sprint event, Kulizhnikov tumbled, and so his team did not finish the run. The fall resulted in Kulizhnikov having his shoulders dislocated. However, the Russian took part in the 500 m distance and achieved victory. After the 500 m, he planned to skip the 1000 m event. Despite that, Kulizhnikov was persuaded not to do that; as a result, he finished the 1000 m event with a new world record (1:05.69).

In the 2019–20 World Cup season, Kulizhnikov missed out the first two stages due to injury received during practice. He then skipped the following stage in Nur-Sultan. He returned to the ice rink in Nagano, collecting four medals, out of which two were gold ones, in 1000 m and, for the first time, in team sprint. In the 1000 m event he set a track record. In the following Calgary stage he set another track record in the same event.

On 8 March 2016 it was reported that Kulizhnikov had failed a drug test, testing positive for meldonium, an anti-ischemic drug added to the World Anti-Doping Agency (WADA)'s banned substances list in 2016. On 13 April, the World Anti-Doping Agency gave amnesty to athletes with the presence of less than 1 microgram of meldonium in doping samples in tests conducted on athletes before 1 March 2016 is acceptable, WADA cites due to uncertainties and lack of studies for how long meldonium stays in the body. On 21 April 2016, the International Skating Union lifted its temporary ban on Kulizhnikov and he was reinstated in the team, since the concentration of meldonium was below the threshold.

the International Skating Union's Official Statement was quoted: "In the case of Meldonium, the WADA recognized that there is currently a lack of clear scientific information on excretion time and considers that in certain circumstances there may be grounds for no fault or negligence on the part of the athlete. All mentioned above skaters credibly assured the ISU that they have discontinued the use of Meldonium prior to 1 January 2016, when the substance was included in the prohibited list. In light of the given information, the ISU has decided to lift the provisional suspension imposed on the four skaters, with immediate effect, to stay the results management process and consequently not to disqualify any results at the present stage."
