Oleg Tsvetkovskiy

At the 2000 Summer Olympics in Sydney, Tsvetkovskiy competed only in two swimming events. He eclipsed a FINA B-cut of 1:55.29 (200 m freestyle) from the Asian Championships in Busan, South Korea. On the first day of the Games, he teamed up with Ravil Nachaev, Petr Vasiliev, and Oleg Pukhnatiy in the 4×100 m freestyle relay. Although he swam the second leg in heat one, his team had been disqualified due to an early relay takeoff by Pukhnatiy. The following day, in the 200 m freestyle, Tsvetkovskiy placed forty-fourth on the morning prelims. He edged out Egypt's Mahmoud El-Wany to lead the first heat by 0.26 of a second in a lifetime best of 1:54.93.

Tsvetkovskiy made his official debut at the 1996 Summer Olympics in Atlanta. He failed to reach the top 16 final in the 100 m freestyle, finishing forty-eighth in a time of 52.39. A member of the Uzbek team, he also placed seventeenth in the 4×100 m freestyle relay (3:28.33), and twelfth in the 4×200 m freestyle relay (7:40.60).
