Dunca's family name was changed from Kőszegi in September 1976, allegedly to sound more Romanian (Kőszegi being a Hungarian name). At that time, she was trying out for the national team. Dunca attended the
1979 World Championships, where she and the rest of the Romanian team won gold. Individually, she was 5th in the all-around. The next year, she competed at the
1980 Summer Olympics, where the Romanian team won silver, and Dunca placed 7th. She competed at her only
European Championships in 1981, where she won bronze on the balance beam and took 4th place in the all-around. At the
1981 Summer Universiade, she won gold in the team event and silver on the balance beam, and she was again 4th in the all-around. Her last competition was the
1982 FIG Artistic Gymnastics World Cup; she finished in 14th place. In 2002, Dunca gave an interview to
ProSport in which she recalled her time training in
Deva, which she called a "concentration camp". She alleged that Romanian head coach
Béla Károlyi starved gymnasts, forbid them from drinking water until they were so thirsty that they drank from toilet tanks, and physically abused gymnasts. She said that in 1980 or 1981, she and
Melitta Rühn as well as
Teodora Ungureanu ran away, but they were caught in
Dej by the
Securitate and forced to return. Afterward, the windows were nailed shut, and the Securitate threatened the gymnasts with harm to their families. She also recalled being forced to take dozens of unknown pills a day. In the same interview, Dunca said that she and the other gymnasts begged
Nadia Comăneci to let them open her fan mail for her. If foreign currency was included, Comăneci let the other gymnasts keep it. == Post-gymnastics career ==
