A randomised trial of an intervention to sustain primary schools’ implementation of a state-wide physical activity policy

To support schools to sustain scheduled physical activity, in particular daily classroom energisers (i.e., short 5-10 minutes class time physical activity breaks), across the school week a multi-strategy sustainability intervention will be offered to schools. 1. Obtain executive support: Executive support will be obtained from educational leaders at the commencement of the study period to illustrate their endorsement of schools scheduling energisers every day. Support will also be communicated to the schools’ staff through an endorsement email template; and the school community through a framed certificate and fence sign to display highlighting them as an ‘Energiser school’. 2. Prompts and support to school champions: Project officers will provide email support to school champions throughout the intervention period to: i) remind teachers to schedule daily energisers; ii) address any new barriers that emerge with school champions; and iii) identify when and if school champion turnover occurs. If a new school champion is identified, project officers will contact them via email, welcoming school champions to their new role and providing them with relevant materials and resources for their role. 3. Provision of resources: A range of resources will be provided to teachers to motivate and remind them to schedule energisers each day, including timetable templates, infographics, resource cards and case studies of successful Energiser schools. Schools will also be provides with electronic resources which can be provided to parents and carers for newsletters and kinder orientation material which explains the importance of energisers and that they are an Energiser school.
