To investigate the effect of cumulative ecological risk (CER) on college students' physical activity patterns (PAP) and to analyze the mediating effect of exercise atmosphere (EA) and self-control (SC), with the aim of promoting the convergence of university physical education with community sports and helping college students to form a healthy physical lifestyle. A total of 966 college students were selected from schools in Beijing, China, and a cross-sectional survey of cumulative ecological risk, physical activity patterns, exercise atmosphere, and self-control was conducted using four scales. Differences, correlations and mediated models were analyzed using ANOVA, Pearson and structural equation modelling (SEM). CER negatively predicted PAP (β=-0.293, P < 0.01), SC (β=-0.523, P < 0.01), and EA (β=-0.352, P < 0.01). EA positively predicted SC (β = 0.358, P < 0.01) and PAP (β = 0.084, P < 0.01), while SC positively predicted PAP (β = 0.256, P < 0.01). Mediation analysis using the Bootstrap method indicated that CER affected PAP both directly and indirectly through three significant paths: Direct effect: CER→PAP (effect size = 0.636). Indirect effects: CER→EA→PAP, CER→SC→PAP, and CER→EA→SC→PAP (combined effect size = 0.364). This also indicates that CER can directly reduce PAP among college students, while effectively enhancing EA and SC, thereby mitigating the negative effects of CER. (1) CER directly affects college students' sport lifestyles, and family and school risks a...
