In order to assess the feasibility of collecting accelerometer and fitness data and the likely change in MVPA and CRF that could be expected from taking part in the program, all participating children took part in the German Motor Ability Test (DMT 6–18) and half of the participants (one class per school) were asked to use a wrist-worn GENEActiv accelerometer (Activinsights Ltd, Kimbolton, UK) for seven consecutive days, 24 h per day, at t0 (Sept and Oct 2021) and t1 (June and July 2022), respectively.The DMT 6–18 [The GENEActiv accelerometer includes a triaxial acceleration sensor (ADXL345) with a ± 8-g dynamic range, is light weight and waterproof and has been shown to provide valid estimates of PA intensities among children [
