Under the background that artificial intelligence (AI) is rising and the National Physical Fitness Assessment Standard (2023 Revised Version) is put in force, this research makes use of smart fitness testing instruments to investigate the influences that aerobic dance brings to the physical fitness of college students. One hundred students in total have been undergone the testing procedure. In this group, 50 students are the majors of aerobic dance, and 50 are the non-art majors. The experiments have covered many aspects, which include body mass index (BMI), body fat proportion, vital capacity, heart-lung endurance, power, flexibility, equilibrium, and reaction time. The results show that students who take aerobic dance as their major have got obviously higher marks in body shape, body function, and whole body fitness level (p < 0.001). The professional training of aerobic dancing is able to effectively promote the promotion of strength, endurance, flexibility and coordination ability.Based on these findings, it is recommended that colleges broaden the scope of aerobic dance courses and enhance intelligent physical fitness monitoring to facilitate the all – around development of students.
