BackgroundPhysical activity levels decline markedly among girls during adolescence. School-based interventions that are multi-component in nature, simultaneously targeting curricular, school environment and policy, and community links, are a promising approach for promoting physical activity. This report describes the rationale, design and baseline data from the Girls in Sport group randomised trial, which aims to prevent the decline in moderate-to-vigorous intensity physical activity (MVPA) among adolescent girls.Methods/DesignA 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 (≥10 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 (± 0.02) years and they spent less than 5% of their waking hours in MVPA (4.85 ± 0.06).DiscussionGirls 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.Trial Registration NumberAustralia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12610001077055

The purpose of this study was to determine the relationship between the aims of course providers and events during the delivery of two soccer coaching accreditation courses. A secondary purpose was to evaluate performance-analysis methods for assessing the course instructor's performance. A case analysis approach was developed to evaluate the courses and the data-gathering process. This research approach was chosen to amalgamate the sources of evidence, providing a multi-dimensional view of course delivery. Data collection methods included simple hand notation and computer logging of events, together with video analysis. The hand notation and video analysis were employed for the first course with the hand notation being replaced with computer event logging for the second course. Questionnaires, focusing on course quality, were administered to participants. Interviews and document analysis provided the researchers with the instructors' main aims and priorities for course delivery. Results of the video analysis suggest a difference between these aims and the events of the courses. Analysis of the questionnaires indicated favourable perceptions of course content and delivery. This evidence is discussed in relation to intent and practice in coach education and the efficiency of employing performance-analysis techniques in logging instructional events.
