Background Grit, defined as perseverance and passion for long-term goals, is a vital psychological trait that contributes to academic success and overall wellbeing. At the same time, regular PA supports physical and mental health, yet its engagement often declines among university students. Although grit has been linked to health-promoting behaviors, the mechanisms underlying this association remain unclear. This study investigated the mediating role of self-efficacy from a variable-centered perspective and identified student profiles based on grit and self-efficacy through a person-centered approach. Methods A cross-sectional survey of 3,752 Chinese university students was conducted. Structural equation modeling tested the mediating role of self-efficacy in the grit-PA relationship. Latent Profile Analysis identified subgroups with distinct combinations of grit and self-efficacy, with PA levels compared across profiles. Results The variable-centered analysis revealed that grit was positively associated with PA ( β = 0.370, p < 0.001), with self-efficacy serving as a significant partial mediator, accounting for 21% of the total effect (indirect effect = 0.077, 95% CI [0.058, 0.097]). The person-centered analysis identified three distinct profiles: “Limited Self-Regulation” (16.12%), “Moderate Self-Regulation” (55.84%), and “Strong Self-Regulation” (28.04%). Students in the Strong Self-Regulation profile demonstrated significantly higher PA engagement ( M = 49.03) compared to ...
