%X A community-based participatory research approach and action learning framework are used with measurements at baseline and 18-month follow-up. Within each intervention school, a committee develops an action plan aimed at meeting the primary objective (preventing the decline in accelerometer-derived MVPA). Academic partners and the State Department of Education and Training act as critical friends. Control schools continue with their usual school programming. 24 schools were matched then randomized into intervention (n = 12) and control (n = 12) groups. A total of 1518 girls (771 intervention and 747 control) completed baseline assessments (86% response rate). Useable accelerometer data (¡Ý10 hrs/day on at least 3 days) were obtained from 79% of this sample (n = 1199). Randomisation resulted in no differences between intervention and control groups on any of the outcomes. The mean age (SE) of the sample was 13.6 (¡À 0.02) years and they spent less than 5% of their waking hours in MVPA (4.85 ¡À 0.06).Girls in Sport will test the effectiveness of schools working towards the same goal, but developing individual, targeted interventions that bring about changes in curriculum, school environment and policy, and community links. By using community-based participatory research and an action learning framework in a secondary school setting, it aims to add to the body of literature on effective school-based interventions through promoting and sustaining increased physical activity participation among adolescent girls.Australia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12610001077055Physical inactivity is one of the leading modifiable risk factors for mortality and morbidity among adults, responsible for an estimated 3.2 million deaths in 2004 [1]. Patterns of activity in adulthood are often established during adolescence [2], making this an important period for promoting physical activity. Moreover, prevalence rates show that adolescent girls are less active than bo
