Evidence is lacking about scalable, effective and sustainable interventions to increase physical activity and concomitant outcomes in young children. Therefore, the investigators will conduct a large cluster randomized controlled trial investigating the effects of physical activity professional development of preschool staff on preschool physical activity practices and child health and development over 6 and 18 months. The aim is to recruit 60 preschools and 1200 children aged 3-5 years in one county in the western part of Norway to allow for detecting small to moderate effect sizes and ensuring a heterogeneous sample of preschools for the study of implementation. Children's physical development, children's socio-emotional and cognitive development, and intervention implementation will be investigated. The intervention will be developed with strong user involvement from municipalities and relevant stakeholders to facilitate the development of sustainable solutions.
