Background Physical activity (PA) consists of multiple domains, including leisure-time PA (LTPA), occupational PA (OPA), and transportation PA (TPA), though limited research has examined these domains among college students. Methods This cross sectional, online survey asked undergraduate students to self-report demographics (gender, race/ethnicity, employment) and PA (LTPA, TPA, and OPA). Participants were categorized as meeting/not meeting current aerobic PA recommendations with only LTPA and with all domains of PA. Analyses examined differences by domain and demographics. Results For participants (n = 3732) when only considering LTPA, 79% met recommendations, while considering all forms of PA resulted in 94% of students meeting recommendations. Gender and race/ethnicity differences in the odds of meeting PA recommendations were present with only LTPA, however when considering all PA domains, some disparities were no longer present. Conclusions These findings highlight how different domains of activity contribute to overall PA and the relationship with gender and race/ethnicity.
