In 2011, a community in central North Carolina launched a grassroots, community campaign to encourage all children and adults to be physically active through enhancement of the built environment and establishment of sustainable opportunities for active living.   The purpose of this project was to evaluate the effect of the community campaign on physical activity levels in elementary school children.  Rapid-Response funding was awarded in order to secure baseline physical activity levels before the campaign begins.  Pre- and post-physical activity levels was measured using accelerometers.
