Assessing the Wider Implementation of the SHARP Principles: Increasing Physical Activity in Primary Physical Education.

To assess the wider application of the SHARP (Stretching whilst moving, High repetition of skills, Accessibility, Reducing sitting and standing, and Promotion of physical activity) Principles intervention on children's moderate to vigorous physical activity (MVPA) in physical education (PE), when applied by teachers and coaches. A quasi-experimental intervention was employed in nine primary schools (experimental, = 6: control, = 3) including teachers ( = 10), coaches ( = 4), and children (aged 5 to 11 years, = 84) in the West Midlands, UK. Practitioners applied the SHARP Principles to PE lessons, guided by an innovative behaviour change model.
