Energy Intake and Expenditure During Sedentary Screen Time and Motion-Controlled Video Gaming

  • Added on July 3, 2012

Background Television watching and playing of video games (VGs) are associated with higher energy intakes. Motion-controlled video games (MC) may be a healthier alternative to sedentary screen-based activities because of higher energy expenditures, but little is known about the effects of these games on energy intakes. Objective Energy intake, expenditure, ...


After-School Setting, Physical Activity, and Sedentary Behavior in 5th Grade Boys and Girls

  • Added on June 28, 2012

After-school hours are considered critical for children's physical activity (PA) and sedentary behaviors (SB); however, whether the after-school setting influences children's activity patterns is unknown. This study examined the influence of after-school setting (i.e., parent report of the child's usual after-school setting) on 5th grade children's PA and SB, ...


Associations of Objectively Measured Sedentary Time and Breaks in Sedentary Time With Cardio-Metabolic Markers in a High Risk UK Population

  • Added on June 15, 2012

Purpose Sedentary behaviour is known to have a detrimental effect on health. However, the manner in which is it accumulated may also be important. Therefore, we examined the association of daily sedentary time and breaks in sedentary time with various markers of cardio-metabolic risk. Methods Cross-sectional analysis using 725 participants from ...


Patterns of Sedentary Behaviour in 7-11 Year Old Children

  • Added on June 15, 2012

Purpose To describe the patterns of sedentary behaviour (SB) across the day and explore relationships with body composition and fitness. Methods 249 children (mean age 8.8 yrs; 56% female) wore an ActiGraph GT1M accelerometer for 7 days, completed a 20m shuttle run fitness test and had triceps and subscapular skinfolds measured. SB was ...


Multi-group and Longitudinal Invariance of Artificial Neural Networks (ANNs) to Predict Physical Activity Type and Physical Activity Energy Expenditure in Children and Adolescents

  • Added on June 15, 2012

Purpose To evaluate the multi-group and longitudinal invariance of ANNs to predict physical activity (PA) type and PA energy expenditure (METs) in youth. Methods The study was conducted at two sites. Site 1 (S1) served as the training and testing sample and comprised 100 youth mean age 11.0 ± 2.7 y. Site 2 (S2) served as ...


Hotspots for Schoolyard Physical Activity – Using GPS, Accelerometry and GIS

  • Added on June 15, 2012

Purpose A number of recent studies have found associations between the characteristics of schoolyards and the level of PA of schoolchildren using the schoolyards. Based on these findings, it seems likely that making schoolyards more attractive will help to increase the total amount of PA among schoolchildren. Before starting our ...


Adaptation and Evaluation of the Active Australia Survey for Internet-Based Self-Administration

  • Added on June 15, 2012

Purpose Evaluate the reliability and validity of a self-reported moderate-to-vigorous physical activity (MVPA) instrument administered by telephone and Internet. Methods The Active Australia Survey (AAS), administered nationally in Australia by telephone (T), was adapted into two forms for Internet self-administration: survey questions only (I-Text) and with videos demonstrating intensity (I-Video). ...



Agreement Between activPAL and ActiGraph for Assessing Children's Sedentary Time

  • Added on February 19, 2012

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) ...


Actigraph Accelerometer-Defined Boundaries for Sedentary Behaviour and Physical Activity Intensities in 7 Year Old Children

  • Added on August 11, 2011

Background Accurate objective assessment of sedentary and physical activity behaviours during childhood is integral to the understanding of their relation to later health outcomes, as well as to documenting the frequency and distribution of physical activity within a population. Purpose To calibrate the Actigraph GT1M accelerometer, using energy expenditure (...
