Objectives
This study examines whether moderate-to-vigorous physical activity (MVPA), in at least 30-min school breaks (SB), helps to achieve the health-related amount of daily physical activity (PA) and whether these exercises influence after-school PA.
Methods
The ActiTrainer-based PA was monitored over two school days in 239 children aged from 9 to 10 (57.3% female; 20.1% ...
Background
Schools provide a unique setting for the promotion of physical activity (PA) in children through structured physical education, recesses, extracurricular sports and promotion of community activities. Because recesses may contribute up to 40% of moderate/vigorous activity, approaches that increase activity during recess are of interest. A number of recent ...
Background
Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender ...
Background
Accelerometers have been used to determine the amount of time that children spend sedentary. However, as time spent sitting may be detrimental to health, research is needed to examine whether accelerometer sedentary cut-points reflect the amount of time children spend sitting. The aim of this study was to: a) ...
This study compared measures of sleep from an accelerometer worn on the hip to measures obtained from an accelerometer worn on the wrist, the gold standard measure of sleep behavior in community research. The accelerometer worn on the hip provides a measure of total sleep time in 10- to 11-year-old ...
The school commute is a prime opportunity to increase children's physical activity levels. However, active commuting has decreased over the past 40 years.
Strategies that increase walking to school are therefore needed. Travelling Green (TG) is a school-based active travel resource aimed at increasing children's walking to school.
The resource consists ...
The purpose of this study was to derive ActiGraph cut-points for sedentary (SED), light-intensity physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) in toddlers and evaluate their validity in an independent sample. The predictive validity of established preschool cut-points were also evaluated and compared. Twenty-two toddlers (mean age = 2.1 years ± 0.4 years) ...
Background
Accelerometers measure levels of physical activity (PA) objectively, and they are being increasingly used to obtain information on PA in children.
Functional Data Analysis (FDA) is a statistical method that can be used to better characterise continuous activity patterns and their variation over time.
The objective of this study ...
Background/Aims
Proponents of the Daylight Saving Bill currently under consideration in the UK parliament have hypothesised that extending afternoon daylight would promote child physical activity. Our aim was to investigate the relative contribution of day length and weather to children's physical activity, and the behavioural mediators underlying these effects.
...
The following fundamental research was not performed explicitly using an ActiGraph device. However, the theories developed in this paper are used extensively in ActiGraph’s ActiLife software.
Objective
Obesity rates in young children are increasing, and decreased physical activity is likely to be a major contributor to this trend. Studies ...
