Sedentary Behavior, Physical Activity, and Abdominal Adipose Tissue Deposition

  • Published on Mar 2017

Purpose: We examined whether sedentary lifestyle habits and physical activity level are associated with abdominal visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), intermuscular adipose tissue (IMAT), and liver attenuation, independently of one another and potential confounders. Methods: This study analyzed 3010 African American and Caucasian men and women, 42–59 yr ...


Physical Activity and Sedentary Time among Children with Disabilities at School

  • Published on Feb 2017

Purposes: Physical activity (PA) is important for the development of children with disabilities, but rarely does this population meet the recommended standards. Schools are salient locations for PA, but little is known about how specific school settings affect the PA of children with diverse disabilities. We assessed PA and sedentary ...


Effects of supervised aerobic and strength training in overweight and grade I obese pregnant women on maternal and foetal health markers: the GESTAFIT randomized controlled trial

  • Published on Sep 29, 2016

Background: During pregnancy, a sedentary lifestyle may have negative consequences on maternal and foetal health status. The main objective of this project is to assess the effects of an exercise intervention in overweight and grade I obese pregnant on maternal and foetal health markers. Methods/Design: The present study aims ...


Empirically derived cut-points for sedentary behaviour: are we sitting differently?

  • Published on Sep 21, 2016

Sedentary behaviour (SB) is associated with a number of adverse health outcomes. Studies that have used ActiGraph monitors to define sedentary time tend to use a threshold of  <100 counts per minute (cpm) for classifying SB; however, this cut-point was not empirically derived for adults. It is not known ...


Longitudinal Growth, Diet, and Physical Activity in Young Children With Cerebral Palsy

  • Published on Sep 7, 2016

Objectives: To describe the longitudinal relationship between height-for-age z score (HZ), growth velocity z score, energy intake, habitual physical activity (HPA), and sedentary time across Gross Motor Function Classification System (GMFCS) levels I to V in preschoolers with cerebral palsy (CP). Methods: Children with CP (n = 175 [109 (62.2%) boys]; mean recruitment age 2 ...


Household-level correlates of children’s physical activity levels in and across 12 countries

  • Published on Aug 25, 2016

Objective: Household factors (electronic media equipment, play equipment, physical activity in the home, and social support) have been associated with childhood moderate- to vigorous-intensity physical activity (MVPA), but little is known about how these factors differ across diverse countries. The objective was to explore household correlates of objective MVPA in ...


Estimating Physical Activity and Sedentary Behavior in a Free-Living Context: A Pragmatic Comparison of Consumer-Based Activity Trackers and ActiGraph Accelerometry

  • Published on Jul 9, 2016

Background: Activity trackers are increasingly popular with both consumers and researchers for monitoring activity and for promoting positive behavior change. However, there is a lack of research investigating the performance of these devices in free-living contexts, for which findings are likely to vary from studies conducted in well-controlled laboratory settings. ...


Does duration of physical activity bouts matter for adiposity and metabolic syndrome? A cross-sectional study of older British men

  • Published on Mar 15. 2016

Background: Older adults have low physical activity(PA) and high sedentary behaviour(SB) levels. We investigate how total volume and specific patterns of moderate to vigorous PA(MVPA), light PA(LPA) and SB are related to adiposity and metabolic syndrome (MS). Then, with reference to physical activity guidelines which encourage ...


School grounds and physical activity: Associations at secondary schools, and over the transition from primary to secondary schools

  • Published on May 2016

This paper aims to further understanding of the physical environments of secondary schools and their associations with young peoples' physical activity. Accelerometer-derived physical activity measurements from 299 participants in the SPEEDY study (Norfolk, UK) were obtained from baseline measurements (age 9–10 y) and +4y follow-up. These were linked to objective measures ...


Investigating elementary school children’s daily physical activity and sedentary behaviours during weekdays

  • Published on Mar 7, 2016

The purpose of the study was to quantify the contributions of physical education, exergaming (active video games that also are a type of exercise), recess, lunch break and after-school time segments to children’s daily physical activity and sedentary behaviours. Participants were 138 second and third graders (71 girls) who attended 20-min ...
