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 ...
Introduction The assessment of energy cost in paediatric populations has typically occurred in laboratory settings, which usually obtain higher validity coefficients. However, laboratory based protocols may be limited in the assessment of free-living behaviours as creating environments that reflect such behaviours is difficult [1]. Few studies have provided children the option ...
Introduction Children have intermittent activity patterns and this must be considered when assessing activity with accelerometers. This study examines the impact of accelerometer epoch duration on the recorded time spent in physical activity during recess. A second goal was to determine whether variability in activity is associated with overall time ...
Introduction The use of motion sensors to objectively measure physical activity (PA) in young children has become increasingly common, due to the various advantages they have over other methods, such as parental report [1]. New and improved motion sensors are continuously being made available, leaving researchers with many methodological [1] and budgetary ...
Introduction Different types of accelerometers are available to assess physical activity (PA) patterns levels, and the choice about which to use depends on various factors: cost, physical characteristics (weight, size, and battery life), performance (number of axes, possible epochs, system of data transfer, recording duration, function of the epochs, and ...
