The need for policies and environments that promote population-wide increases in physical activity is urgent, given that less than 50% of U.S. adults meet the recommendations for moderate and/or vigorous physical activity. There are various ways to engage in the policy process ranging from educating policymakers about existing research, to promoting evidence-based policymaking, to ensuring that policies are implemented well. Such insights are critical for realizing greater use of available evidence in active living policy decisions. This workshop highlighted evidence about how science is used to inform policy decisions and implementation practices, and complemented the existing literature with their own practice-based experiences. Participants learned how researchers and practitioners can more effectively engage in the different stages of the policy process to promote active living research. Participants practiced what they learn during small group and role-play exercises. This interactive workshop involved didactic instruction and provided participants with concrete strategies and skills needed to advance evidence-based and evidence-informed active living interventions throughout the policy process.
