Objective: Two studies were conducted to examine the relationship between past physical activity, concurrent self-regulatory efficacy (CSRE), and current physical activity during the transition to university. Participants: Study 1 included 110 first-year undergraduate students recruited during October/November of 2012. Study 2 involved 86 first-year undergraduate students recruited during October/November of 2013. Methods: Surveys were completed online, concurrently (Study 1) and prospectively (Study 2). Results: CSRE was found to positively predict current physical activity participation in both studies. However, the relation of CSRE to physical activity was attenuated when past behavior was taken into account. Conclusions: Physical activity is one goal that university students pursue concurrently with other goals. Not only is current planned activity related to one's past participation in physical activity, it is also related to self-regulatory beliefs about managing that activity in the new context of university life.
