Based on the four hypotheses of sports persistence formation theory, this paper analyzes the influencing factors of college students' exercise persistence by using the methods of literature and logical analysis, and holds that: persistence in exercise is the result of the comprehensive effect of various influencing factors, and the factors are summarized into 6 categories and 22 items; the psychological dependence of the exerciser on exercise behavior is the key factor; the frequency, length of exercise, strength of exercise are closely related to exercise persistence. Based on this, the author puts forward that the persistence mechanism of college students' physical exercise behavior is the determined by individual sports motivation and the promotion of social factors, and suggests that three prevention and intervention methods should be adopted for passive sports addiction.
