Abstract
BackgroundSchool-based physical activity interventions evaluating the effect on academic performance usually includes children. We aimed to investigate the effect of a nine-month, school-based physical activity intervention titled School in Motion (ScIM) on academic performance in adolescents.MethodsThirty secondary schools in Norway were cluster-randomized into three groups: the Physically active learning (PAL) group (n = 10), the Don’t worry – Be Happy (DWBH) group (n = 10) or control (n = 10). Target dose in both intervention groups was 120 min/week of additional PA during school hours. Parental consent was obtained from 2084 adolescent students (76%). Standardized national tests in reading and numeracy was conducted at baseline and at the end of the intervention. We used linear mixed model to test intervention effects. We found significant intervention effects in numeracy and reading among students in both interventions when compared with controls.ResultsThe mean difference in change in numeracy was 1.7 (95% CI: 0.9 to 2.5; Cohen’s d = 0.12) and 2.0 (95% CI: 1.4 to 2.7; Cohen’s d = 0.23) points in favour of students in the PAL and DWBH intervention, respectively. Similar results were found for reading, where the mean difference in change was 0.9 (95% CI 0.2 to 1.6; Cohen’s d = 0.06) and 1.1 (95% CI 0.3 to 1.9; Cohen’s d = 0.18) points in favour of students in the PAL and DWBH intervention, respectively. When conducting intention to treat analysis with imputed data the estimates were attenuated and some no longer significant.ConclusionThe ScIM study demonstrates that two different school-based PA interventions providing approximately 120 min of additional PA weekly over nine months, significantly improved numeracy and reading performance in 14-year old students compared with controls. However, the results should be interpreted with caution as the effect sizes reported were very small or small and the estimates were attenuated when conducting intention to treat analysis. Despite this, our results are still positive and suggest that PA interventions are viable models to increase academic performance among adolescents.Trial registrationRetrospectively registered (25/01/2019): NCT03817047.

The School in Motion (ScIM) study demonstrates that two different school-based Physical activity (PA) interventions providing approximately 120 min of additional PA weekly over nine months, significantly improved numeracy and reading performance in 14-year old students compared with controls
We recently reported a favourable effect on the daily PA level and the time spent in moderate-to-vigorous intensity physical activity (MVPA) among adolescents in one of the intervention arms compared with controls [14]
Summary
School-based physical activity interventions evaluating the effect on academic performance usually includes children. A randomized controlled trial (RCT) called Physical Activity Across the Curriculum, found improved performance in reading, numeracy, and spelling in a sub sample comparing children who received physically active lessons daily for three years with children who followed the regular curriculum [7]. In the Fit & Vaardig op School study, weekly physically numeracy and language lessons over two years improved numeracy and spelling performance among elementary school children [8]. These results correspond with the Activity and Motivation in Physical Education trail findings, where the authors reported significant intervention effects on numeracy performance [9]
