Born in Dnipropetrovsk, her breakthrough in the triple jump came in 1991 when she broke the world record with a clearance of 14.95 metres in June.

At the inaugural appearance of the women's triple jump at the 1992 European Athletics Indoor Championships she won the gold medal.

Later that year at the 1992 Summer Olympics she claimed the long jump silver as part of the Unified Team.

She followed this with a gold medal at the first women's triple jump at the 1993 IAAF World Indoor Championships, but due to a doping ban she did not compete at the debut of the event at the 1993 World Championships in Athletics, where Russia's Anna Biryukova took the title.
