A Cluster-Analytic Classification of Children's Physical Activity: The Change! Project

  • Added on July 22, 2011

Introduction Physical activity is a major public health concern as trends show inadequate levels of physical activity for health and rising levels of obesity. A research priority is understanding key explanatory variables underpinning children’s physical activity participation. Despite this, there are few studies identifying “clusters” of children based on ...


Can a 6 Week School Based Active Play Intervention Increase Moderate-to-Vigorous Physical Activity and Decrease Sedentary Behaviour?

  • Added on July 22, 2011

Introduction There is concern that preschool children are not physically active enough to benefit health, yet few interventions have attempted to increase physical activity (PA) in this population. This study aimed to investigate the effectiveness of a 6-week school based Active Play intervention on children’s moderate-to-vigorous physical activity (MVPA) ...


Comparison of Accelerometer Cut Points for Predicting Activity Intensity in Youth

  • Published on 07/01/2010

The absence of comparative validity studies has prevented researchers from reaching consensus regarding the application of intensity-related accelerometer cut points for children and adolescents. Purpose This study aimed to evaluate the classification accuracy of five sets of independently developed ActiGraph cut points using energy expenditure, measured by indirect calorimetry, as ...






International Children's Accelerometry Database (ICAD): Design and Methods

  • Added on June 21, 2011

Over the past decade, accelerometers have increased in popularity as an objective measure of physical activity in free-living individuals. Evidence suggests that objective measures, rather than subjective tools such as questionnaires, are more likely to detect associations between physical activity and health in children. To date, a number of studies ...


Predicting Children's Free-living Energy Expenditure

  • Added on June 16, 2011

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 ...


Impact of Accelerometer Epochs on Classification of Children Activity Patterns

  • Added on June 16, 2011

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 ...
