China’s level of sports aerobics is in the top class. As a non-Olympic event, some athletes participated in aerobics from youth, while others from other events. Athletes from different events have different traits, which lead to different performance. This paper takes high level athletes of aerobic gymnasts for example, in order to analyze the different sources of high level athletes of aerobics gymnasts, with the methods of literature, questionnaire survey, mathematical statistics and expert interviews. The results of the study shows that: (1) most of high level athletes of aerobic gymnasts came from gymnastics events; (2) the number of China’s aerobic champions that come from aerobics is increasing; (3) the gymnasts which only came from aerobics take an advantage among common high level athletes., and they are outstanding talents in universities; (4) most high level athletes who participate in aerobics aim to be admitted to better universities. Only minority of them are because of love or promotion for higher level of their aerobics skills.
