Physical activity (PA) levels in children are too low. A classroom-based PA intervention is an effective way to increase PA. In order to make such an intervention successful, it should not negatively affect school performance. ‘Fit & Vaardig op school’ (F&V) is a classroom-based PA intervention with integrated learning material. The primary aim was to investigate whether F&V increases time on-task (TOT) immediately after the intervention. The secondary aim was to investigate whether relative intensity influences this possible increase in TOT. Participants were 82 children (mean age=8.93 years) of four elementary schools. The children were measured on an intervention day (children’s TOT was observed during the 30 minutes before and after the F&V lesson) and a control day (children were observed 30 minutes before and after a regular lesson). Both test days were executed in two periods during the school year. Heart rate was measured during intervention lessons to calculate relative intensity. Results showed no significant interaction effect of time and intervention on TOT, for both periods (p>.05). In period two, this interaction was significantly different between schools (p<.05). A significant weak correlation (r=-.30; p<.05) in period two indicated that high relative intensity was related with a decrease in TOT. The change in TOT between before and after the intervention was not significantly different between children that spent more, and children that spent less than 10 minutes in moderate to vigorous intensity PA (both periods: p>.05). Concluding, children’s change in TOT over time was not significantly different between the control and intervention situation. A high relative intensity seems to negatively influence the change in TOT. Future studies could investigate why the effect of the intervention is different per school.
