Arslan discovered kickboxing at the age of 23 as her younger sister started to attend a new gym,[3] which opened in a local basement.[4][5][6] The gym owner, Hasan Fahri Şen, was a former Turkish champion in martial arts and a coach.[5] He offered to start training her for kickboxing. In the beginning, she was not interested because she had to work until late leaving little spare time and she was very tired after work. She also smoked two packs of cigarettes a day, and coughed up dust due to the conditions in her workplace.[4][6] The coach and Deniz Işık Doğan persuaded her to begin training in the gym.[5] She soon realized that kickboxing was very different from what she had thought. She exercised three days a week, and made great progress as a sportswoman in the first four months.[2][4]
Arslan became the Turkish champion for three consecutive years.[6] In 2015, she debuted internationally and she won a gold medal at the Intercontinental Kickboxing Mauritius Cup event.[6] She won the silver medal at the 2016 European Championship in Maribor in Slovenia,[6][7] and the gold medal at the 2019 World Seniors Kickboxing Championship in Antalya in Turkey. [4][5] In 2021, she captured the gold medals at the World Kickboxing Seniors Championship in Jesolo, Italy[8] and the 2021 Islamic Solidarity Games in Konya, Turkey.[9] At the 2023 European Games in Myślenice, Poland, she was the champion.[1]
