  • Tensions and Paradoxes of Scaling Up

    Open AccessHarriet Koorts, Adrian Bauman et al.ARTICLEInternational Journal of…2022

    Achieving system-level, sustainable 'scale-up' of interventions is the epitome of successful translation of evidence-based approaches in population health. In physical activity promotion, few evidence-based interventions reach implementation at scale or become embedded within systems for sustainable health impact. This is despite the vast published literature describing efficacy studies of small-scale physical activity interventions. Research int…

  • Controversies in the Science of Sedentary Behaviour and Health

    Open AccessStuart Biddle, Jason A Bennie et al.ARTICLEInternational Journal of…2019

    The development in research concerning sedentary behaviour has been rapid over the past two decades. This has led to the development of evidence and views that have become more advanced, diverse and, possibly, contentious. These include the effects of standing, the breaking up of prolonged sitting and the role of moderate-to-vigorous physical activity (MVPA) in the association between sedentary behaviour and health outcomes. The present aim is to…
