Abstract
Physical inactivity is a global challenge that necessitates early intervention during childhood. Schools are positioned to make a significant impact on children's current and future physical activity behavior, but numerous barriers hinder the implementation and sustainability of school-based physical activity opportunities. The purpose of this invited article is to provide an overview of the comprehensive school physical activity program (CSPAP) as a concept, framework, and promising approach to institutionalizing physical activity within the school environment. Despite the availability of numerous published reviews on the topic, a broad, up-to-date panorama of the CSPAP literature that encompasses and consolidates historical, conceptual, empirical, and practical perspectives is currently lacking. Contained within this article is an explanation of the public health context that undergirds the CSPAP concept, a historical perspective of the concept's origins and evolution, examples of CSPAP research, recommendations for advancing the knowledge base, and evidence-informed frameworks and principles for professional practice.
