Key PointsQuestionDoes an internet-based intervention for teachers improve children’s cardiorespiratory fitness when delivered across a large number of schools? FindingsIn this cluster randomized clinical trial of 22 schools including 1188 students, use of the internet-based intervention significantly improved children’s cardiorespiratory fitness at 12 months. Follow-up assessments at 24 months showed a sustained effect. MeaningResults of this randomized clinical trial suggest that the intervention has potential to be scaled to benefit children’s health at a population level.
