In order to explore the relationship between meanings of life and exercise behavior of college students,
and the mechanism of general self-efficacy and exercise self-efficacy between them. 302 college students were
investigated as subjects to conduct questionnaires. The results found: (1) The meaning of life, exercise behavior,
general self-efficacy and exercise self-efficacy are significantly positively correlated. (2) The meaning of life
positively predicts exercise behavior, and at the same time predicts exercise behavior through multiple mediating
effects of general self-efficacy and exercise self-efficacy. Conclusion: The meaning of life and exercise self-efficacy
are important predictors of exercise behavior. The effect of general self-efficacy on exercise behavior is entirely
through exercise self-efficacy. This study provides an empirical basis for strengthening the education of meaning
of life about college students and the role of improving exercise self-efficacy in promoting exercise behavior
