Background: Larger brain volumes are often associated with more free-living physical activity (PA) in cognitively normal older adults. Yet, whether greater brain volumes are associated with more favorable (less fragmented) PA patterns, and whether this association is stronger than with total PA, remains unknown. Methods: Brain magnetic resonance imaging and ...
Abstract: Low and middle-income countries in Asia and Africa have been witnessing a process of rural transformation, characterised by rising agricultural productivity, commercialisation of agriculture, improved infrastructure and access to services, over several decades. However, there is little empirical evidence on how this transformation process has affected the patterns and ...
Abstract: Women’s patterns of time-use, which proxy the work burdens associated with productive and reproductive activities, are an important determinant of nutrition and well-being in LMICs. However, there is a lack of empirical evidence on how patterns of time-use translate into patterns of physical activity and energy expenditure, particularly ...
Background: Individuals with Down syndrome (DS) are less physically active than the general population, but limited data on objective physical activity patterns in adults with DS are available. Methods: Free-living physical activity was measured by waist-worn accelerometry in adults with DS from 2018 to 2020. Data were analysed using descriptive statistics, bivariate ...
Introduction Exercising in hot conditions may increase the risk for exertional heat-related illness due to reduction in cerebral blood flow (CBF); however, the acute effect of exercise-induced changes on CBF during compensable and uncompensable heat stress remain unclear. We tested the hypothesis that exercising in hot dry and humid conditions ...
Abstract Although regular physical activity is recommended for health, highly contaminated air exposure acts to the detriment of the benefits produced in individuals. The purpose of the present study was to compare the accelerometer-measured physical activity and sedentary behavior during the whole day, in-school time, out-of-school time, and school breaks ...
Background ACE (Active, Connected, Engaged) is a theory-informed, pragmatic intervention using peer volunteering support to promote active ageing in socially disengaged, inactive older adults. This study aimed to establish ACE’s feasibility and acceptability. Methods Fifty-four older adults were recruited as either peer volunteers (activators; n = 15) or participants (ACEs; n = 39). ...
Background The built environment can affect health behaviours, but longitudinal evidence is limited. We aimed to examine the effect of moving into East Village, the former London 2012 Olympic and Paralympic Games Athletes' Village that was repurposed on active design principles, on adult physical activity and adiposity. Methods In this cohort ...
Purpose The purpose was to examine the feasibility and preliminary effectiveness of two built environmental interventions with Head Start preschool children to increase minutes and intensity and total physical activity (PA). Design and Methods A prospective, quasi‐experimental, repeated measures design was conducted in two Head Start centers. Centers were ...
Abstract As activity space measures are increasingly used to estimate exposure to environmental determinants of health, little is known about the stability of these measures over time. To test the stability of GPS-derived measures of activity-space footprint, size, and environmental features over time, we compared 14-day measures at baseline and ...
