Abstract Background: Inadequate physical activity in young people is associated with several physical and mental health concerns. Physical education (PE) is a potentially viable existing network for promoting physical activity in this population. However, little research has been conducted on whether PE teachers can influence students’ engagement in leisure-time physical activity. The present study therefore examined the efficacy of an intervention aimed at increasing PE teachers’ autonomy support on students’ leisure-time physical activity (the PETALS trial). The intervention was guided by the trans-contextual model (TCM) explaining the processes by which PE teachers’ provision of autonomy support during PE promotes students’ motivation and engagement in physical activity in their leisure time. Methods: The study adopted a cluster-randomized, waitlist control intervention design with randomization by school. Participants were PE teachers (N = 29, 44.83%female; M age = 42.83, SD = 9.53 yrs) and their lower secondary school students (N = 502, 43.82%female; M age = 14.52, SD = 0.71 yrs). We measured TCM constructs, including perceived autonomy support, autonomous motivation in PE and leisure time, beliefs and intentions towards leisuretime physical activity, and physical activity behavior at baseline, post-intervention, and at one-, three-, and sixmonths. Study hypotheses were tested through a series of ANOVAs and structural equation models using postintervention and one-month follow-up data. (Continued on next page)
