Implementation of a School Physical Activity Policy Improves Student Physical Activity Levels: Outcomes of a Cluster-Randomized Controlled Trial.

Aim: To assess the impact of a multistrategy intervention designed to improve teachers' implementation of a school physical activity (PA) policy on student PA levels.

Methods: A cluster-randomized controlled trial was conducted in 12 elementary schools. Policy implementation required schools to deliver 150 minutes of organized PA for students each week via physical education, sport, or class-based activities such as energizers.

Barriers to and Facilitators of the Implementation of Environmental Recommendations to Encourage Physical Activity in Center-Based Childcare Services: A Systematic Review.

Background: Identifying factors influencing the implementation of evidence-based environmental recommendations to promote physical activity in childcare services is required to develop effective implementation strategies. This systematic review aimed to: (1) identify barriers and facilitators reported by center-based childcare services impacting the implementation of environmental recommendations to increase physical activity among children, (2) synthesize these factors according to the 14 domains of the "Theoretical Domains Framework," and (3) report any associations between service or provider characteristics and the reported implementation of such recommendations.

Methods: Electronic searches were conducted in 6 scientific databases (eg, MEDLINE) and Google Scholar to identify studies reporting data from childcare staff or other stakeholders responsible for childcare operations.

Barriers and facilitators to the implementation of physical activity policies in schools: A systematic review.

Unlabelled: Research consistently indicates that schools fail to implement mandatory physical activity policies. This review aimed to describe factors (barriers and facilitators) that may influence the implementation of school physical activity policies which specify the time or intensity that physical activity should be implemented and to map these factors to a theoretical framework. A systematic search was undertaken in six databases for quantitative or qualitative studies published between 1995-March 2016 that examined teachers', principals' or school administrators' reported barriers and/or facilitators to implementing mandated school physical activity policies.
