Career
Shemarov made his official debut at the 2000 Summer Olympics in Sydney, where he competed in the men"s heavyweight division (97 kg). He scored a set of two triumphs to defeat Canada"s Dean Schmeichel and Slovak-born Australian wrestler Gabriel Szerda in the opening matches, but suffered a formidable 2–3 overtime defeat against Poland"s three-time Olympian Marek Garmulewicz. Finishing second in the prelim pool and seventh overall, Shemarov"s performance fell short to put him further into the quarterfinals.
At the 2004 Summer Olympics in Athens, Shemarov qualified for his second Belarusian squad, as a 29-year-old, in the men"s heavyweight class (96 kg) by rounding out the top ten spot and receiving a berth from the 2003 World Wrestling Championships in New York City, New York, United States.
Shemarov delivered a more powerful effort from his previous Games by thrashing Turkey"s Fatih Çakıroğlu and Mongolia"s Tüvshintöriin Enkhtuyaa to secure a spot for the next round.
