Designing programmes of physical activity through sport: learning from a widening participation intervention, 'City of Football'.

Background: Implementation profoundly influences how well new audiences engage with sport-based physical activity programmes. Recognising that effective implementation relies on concurrently generating supportive contexts, systems and networks for the least engaged 'target' groups; this paper aims to address what underpins children's (non) engagement with football-based physical activity.

Methods: An observational research design, using a non-probability sample of N = 594 primary and secondary schoolchildren assessed outcomes of a three-year 'City of Football' (CoF) programme.

Physical Activity and Sedentary Behavior Clustering: Segmentation to Optimize Active Lifestyles.

Background: Increasingly the health impacts of physical inactivity are being distinguished from those of sedentary behavior. Nevertheless, deleterious health prognoses occur when these behaviors combine, making it a Public Health priority to establish the numbers and salient identifying factors of people who live with this injurious combination.

Methods: Using an observational between-subjects design, a nonprobability sample of 22,836 participants provided data on total daily activity.
