Mărănducă started gymnastics at the age of 6 at Farul ConstanţaClub. In 1991 she became the first gymnast from that club to be selected to the national team. At the beginning of her senior career she was not selected to participate at major international competitions. Instead she competed at the Romanian Internationals and Romanian Nationals. In 1993 she finished third all around at the Romanian Internationals behind Lavinia Miloșovici and Lyudmila Stovbchataya. Soon after this competition she broke her ankle and severely sprained her wrist during practice. She was told that she would not be able to return to gymnastics but after recovering from her injuries she went back to Constanţa to train with the junior team. She made it back in the national team in 1994. Her determination to return to the national team was a great inspiration to the juniors training at Farul. Among these juniors was Simona Amânar who declared that seeing Mărănducă train and returning to the national team was "the best lesson had ever learned". 1994 was a good year for Mărănducă. She won several medals at some minor competitions and went with the team in Dormunt to compete in the 1994 World Championships. Her performance on all four events, highlighted by a 9.8 on vault and a 9.837 on floor, helped the team to win the gold medal. She was also voted the most beautiful gymnast by the journalists covering the championships. Mărănducă retired from artistic gymnastics at the end of 1994 and went back to Constanţa where she majored in Environmental studies and helped with coaching at Farul.
After retiring from artistic gymnastics Mărănducă went to perform in the Aeros entertainment show. Among her colleagues at Aeros were Izabela Lăcătuș, Lăcrămioara Filip, Cristian Leric and Remus Nicolai. In 1996 she started to train for aerobic gymnastics and in 1999 she was selected to be a member of the national aerobic team trained by Maria Fumea. During her aerobic gymnastics career she won two world titles and three continental titles for the group event. She also won a world championshipsbronze medal and two European championships silver medals and placed fifth at the 2002 world championships on the trio event. Mărănducă retired from aerobic gymnastics in 2005.
