[1][2] Oleksandr Konovaliuk was born on May 1, 1978 in the city of Nova Kakhovka, Kherson region, Ukrainian SSR.
He began rowing in 1992 and three years later he joined the Ukrainian national team and competed in the Junior World Championships in Poznan, where he took sixth place in the eights.
In the same year, he failed to make it into the medalists at the World Championship in Carapiro, limiting himself to the final B.
Thanks to a series of successful performances, he earned the right to compete at the 2012 Summer Olympics in London - as part of a team that also included rowers Anton Kholyaznykov, Viktor Hrebennikov, Ivan Tymko, Artem Moroz, Andriy Pryveda, Valentyn Kletskoy, Oleh Lykov and Serhiy Chykanov.
After the London Olympics, Konovaliuk remained in the main lineup of the Ukrainian national team and continued to take part in major international regattas.
