This framework comprises four pillars aimed at the development of: (a) an empirical definition of VILPA, (b) methods to reliably and accurately measure VILPA, (c) approaches to examine the short and long-term dose-response effects of VILPA, and (d) scalable and acceptable behavioural VILPA-promoting interventions. To encourage collaboration and research agenda alignment among groups interested in this field, we propose a research framework to further understanding of vigorous intermittent lifestyle physical activity (VILPA). Key gaps include the absence of an empirically-derived dose specification (e.g., minimum duration of lifestyle physical activity required to achieve absolute or relative vigorous intensity), lack of acceptable measurement standards, limited understanding of acute and chronic (adaptive) effects of intermittent vigorous bouts on health, and paucity of essential information necessary to develop feasible and scalable interventions (e.g., acceptability of this kind of physical activity by the public). Despite this recognition and the advantages such lifestyle physical activity has over continuous vigorous intensity structured exercise, a scoping review we conducted revealed that current research in this area is, at best, rudimentary. Recently revised public health guidelines acknowledge the health benefits of regular intermittent bouts of vigorous intensity incidental physical activity done as part of daily living, such as carrying shopping bags, walking uphill, and stair climbing. 14 Department of Kinesiology, McMaster University, Hamilton, ON, Canada.13 Department of Kinesiology, College of Health and Human Services, University of North Carolina at Charlotte, Charlotte, NC, USA.12 Doctoral College, Ulster University, Newtownabbey, Co Antrim, BT37 0QB, Northern Ireland, UK.11 Institute Sport Exercise Health, Faculty Medical Sciences, University College London, London, UK.10 School of Sport, Exercise and Health Sciences, Loughborough University, Loughborough, UK.9 Institute of Musculoskeletal Health, University of Sydney, Sydney School of Public Health, Faculty of Medicine and Health, Sydney, Australia.8 Department of Health Systems and Populations, Macquarie University, Sydney, Australia.7 National Research Centre for the Working Environment (NRCWE), Copenhagen, Denmark.6 Physical Activity and Behavioural Epidemiology Laboratories, Baker Heart and Diabetes Institute, Melbourne, Australia.5 School of Sport, Exercise and Rehabilitation Sciences, University of Birmingham, Birmingham, UK.4 Physical Activity and Well-Being Research Group, School of Psychology, Curtin University, Perth, Australia.3 Allied Health and Human Performance, University of South Australia, Adelaide, Australia.2 School of Health Sciences, Charles Perkins Centre, The University of Sydney, Faculty of Medicine and Health, Hub D17, L6 West, Sydney, NSW, Australia. 1 School of Health Sciences, Charles Perkins Centre, The University of Sydney, Faculty of Medicine and Health, Hub D17, L6 West, Sydney, NSW, Australia.
