Abbreviations: CI confidence interval, CF cognitive functioning, VLT verbal learning test, SST stop-signal task, SSRT stop-signal reaction time, LDST letter digit substitution test, MVPA moderate-to-vigorous physical activity per week.* Effects are reported as intervention group vs control group as the control group served as a reference group in the different subgroups. Subgroups were predetermined based on paper on effects on PA. 1 Assessed at baseline; Guidelines prescribe 150 min of MVPA per week
