Implementation Outcomes and Recommendations of Two Physical Activity Interventions: Results from the Danish ACTIVE SCHOOL Feasibility Study

Physical activity (PA) should be an essential part of all children’s lives, as it can promote physical and mental health, enhance general well-being, and positively impact learning outcomes. Schools offer an ideal setting to encourage physical activity during the school day, as nearly all children attend school. However, schools present a complex environment for implementing PA, and sedentary behavior is common in classroom teaching. This study explores the feasibility of two types of school-based physical activity interventions: one based on research in exercise and cognition (Run, Jump & Fun) and another grounded in embodied learning (Move & Learn). Run, Jump & Fun can be conceptualized as extra non-curricular physical activity implemented into the school day while Move & Learn is integrated into curricular time. The 8-week study involved third-grade students and their teachers from seven schools, with educational strategies applied to support adoption. Quantitative and qualitative data were collected before, during, and after the 8-week period. The results indicated that both interventions were feasible to implement, leading to a series of recommendations for further refinement. These recommendations can guide the development of future school-based PA interventions and inspire other researchers to assess and improve their implementation strategies.
