Introduction Most accelerometry research is in children and adults. Literature on accelerometry in older adults is limited and many studies rely on validity studies completed on younger adults to determine cutpoints for exercise intensity. The purpose of this study was: to review the literature to identify studies that used ActiGraph ...
Introduction The interest in physical activity (PA) to prevent pediatric obesity has increased during the past decade. However, to start with obesity preventative efforts, adequate measurements of PA are needed. Although accelerometers have been put forward as an adequate method to assess preschoolers’ PA, survey measures of PA can be ...
Introduction The most popular accelerometers in physical activity research are the Actigraph uniaxial accelerometer (AGR, Model GT1M, Actigraph, Shalimar, CA) and the RT3 triaxial accelerometer (Stayhealthy Inc, Monrovia, CA). When a large population is evaluated at the same time, the use of several accelerometers is necessary. To be able ...
Introduction The aims of this study were to assess the quality of data on physical activity obtained by recall from British Pakistani women, and to explore the feasibility of using accelerometer-based physical activity monitors to provide more objective measure of physical activity in this group. Previously only questionnaire data have ...
Introduction Accurate measurement of canine physical activity (PA) is important in obesity treatment and prevention in veterinary medicine [1]. Methods of PA measurement often rely on owner recall and thus open to the same cognitive problems recognised in human PA measurement [1]. Accelerometry has been shown to be a valid, practical and ...
Introduction Sitting at work is an emerging occupational health risk [1]. Few instruments designed for use in population-based research measure occupational sitting and standing as distinct behaviours [2]. The aim of this study was to develop and validate a brief measure of occupational sitting and physical activity. Methods A convenience sample (N=99, 61% ...
Introduction It is important to understand the determinants of physical activity needed to influence policy and create environments that promote physical activity among preschool children. Physical activity levels were studied with the aims to compare outdoor and indoor activity and to analyze minutes spent in sedentary, light, moderate and vigorous ...
Introduction South Asian minority groups in the UK are at greater risk of heart disease and diabetes than the general White population. Physical activity plays an important role in the onset of these diseases. A recent study using accelerometers showed that girls had lower levels of physical activity than boys, ...
Introduction There is no consistency in the literature as to the amount of accelerometry monitoring time required to reliably determine habitual physical activity behaviour in preschool children. This study aims to identify how many days, and what percentage of time each day, of monitoring is required. Methods Data from ActiGraph ...
Purpose To examine the change in the average daily steps taken at different cadence (steps/min) levels when a change in total steps/day occurs. Methods A total of 43 people participated in a one week intervention with the goal to increase time spent in moderate-to-vigorous physical activity. Participants wore a ...
