The peak of her career came in the 1974 season. She started with an indoor national double in the 60 m hurdles and 60 metres sprint.[6] She placed sixth at the 1974 European Athletics Indoor Championships in the hurdles.[4] Outdoors she proved herself as Hungary's most versatile athlete with wins in the long jump, 100 m hurdles and pentathlon. Her winning mark of 6.63 m (21 ft 9 in) in the long jump was a personal best for the athlete and a Hungarian championship record.[2] She was selected for both long jump at the pentathlon at the 1974 European Athletics Championships. Her first final was the long jump and she produced a lifetime best performance of 6.65 m (21 ft 9+3⁄4 in) to break the Hungarian national record and take the gold medal ahead of Eva Šuranová of Czechoslovakia. Despite this additional efforts, she still managed to place sixth in the pentathlon event and was the only athlete in the top seven not to come from either East Germany or the Soviet Union.[7] For her achievements she was chosen as the Hungarian Sportswoman of the Year.[8]
Bruzsenyák did not compete in major international competition in 1975, but took national indoor titles in the hurdles and long jump that year.[6] The 1976 season was her last at a high level. She was the sprint hurdles champion indoors and outdoors.[2] Alongside the national champions Ildikó Erdélyi and Margit Papp, she was chosen again for the long jump and pentathlon at the Olympics. At the 1976 Montreal Games her decline on the international scene was evident as she failed to progress beyond the long jump qualifiers and dropped to sixteenth in the pentathlon rankings.[1] The following year she won the last national title of her career, the indoor 60 m hurdles.[6]
Bruzsenyák married Lajos Gresa, a fellow Hungarian international athlete.[1]
