Objective: To evaluate the relationship between high school sport participation among university students and whether previous sports participation was associated with current levels of exercise self-efficacy, resilience, and psychological need satisfaction physical activity behaviors. Participants: College freshmen (n = 152) in the United States responded to an electronic survey sent out by their university. Methods: Participants completed a set of questionnaires assessing resilience, psychological need satisfaction in exercise, self-efficacy, and current PA. Results: Analysis of variance, Kruskal-Wallis H tests, independent samples t-tests, and ordinary least squares regression modeling were used. Total PA and having met moderate PA guidelines were both associated with exercise SE and PNSE. HS GPA, total PA, and being a college athlete were associated with both resilience and exercise SE. Conclusions: Sport participation may serve as an effective method for students to develop exercise SE, resilience, and PNSE. The development of these skills may support lifelong PA behaviors.
