Testing the activitystat hypothesis: a randomised controlled trial

  • Published on Aug 30, 2016

Abstract: It has been hypothesised that an ‘activitystat’ may biologically regulate energy expenditure or physical activity levels, thereby limiting the effectiveness of physical activity interventions. Using a randomised controlled trial design, the aim of this study was to investigate the effect of a six-week exercise stimulus on energy expenditure ...


Physical Activity Assessment Between Consumer- and Research-Grade Accelerometers: A Comparative Study in Free-Living Conditions

  • Published on Jul 2016

Background: Wearable activity monitors such as Fitbit enable users to track various attributes of their physical activity (PA) over time and have the potential to be used in research to promote and measure PA behavior. However, the measurement accuracy of Fitbit in absolute free-living conditions is largely unknown. Objective: To ...


Different Methods Yielded Two-Fold Difference in Compliance with Physical Activity Guidelines on School Days

  • Published on Mar 25, 2016

Introduccion: The aim was to compare the average and the days method in exploring the compliance of children with physical activity guidelines and describe their physical activity patterns in different school day segments. Methods: Physical activity was objectively measured in 472 children aged 6–13 for one school week. Children were compliant ...


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 ...


Places where preschoolers are (in)active: an observational study on Latino preschoolers and their parents using objective measures

  • Published on Feb 29 2016

Background: To combat the disproportionately higher risk of childhood obesity in Latino preschool-aged children, multilevel interventions targeting physical (in) activity are needed. These require the identification of environmental and psychosocial determinants of physical (in) activity for this ethnic group. The objectives were to examine differences in objectively-measured physical activity and ...


Physical activity and risk of breast cancer, colon cancer, diabetes, ischemic heart disease, and ischemic stroke events: systematic review and dose-response meta-analysis for the Global Burden of Disease Study 2013

  • Published on Aug 9, 2016

Objective: To quantify the dose-response associations between total physical activity and risk of breast cancer, colon cancer, diabetes, ischemic heart disease, and ischemic stroke events. Design: Systematic review and Bayesian dose-response meta-analysis. Data Sources: PubMed and Embase from 1980 to 27 February 2016, and references from relevant systematic reviews. Data from the Study ...


A non-equivalent group pilot trial of a school-based physical activity and fitness intervention for 10–11 year old english children: born to move

  • Published on Aug 24, 2016

Background: PE lessons are the formal opportunity in schools for promotion of physical activity and fitness. This study aimed to evaluate the effectiveness of a pilot PE intervention on physical activity, fitness, and psychosocial outcomes. Methods: Participants were 139 children aged 10–11 years from four schools. For six weeks children in ...


Comparison of wrist-worn Fitbit Flex and waist-worn ActiGraph for measuring steps in free-living adults

  • Published on Feb 24, 2017

Introduction: Accelerometers are commonly used to assess physical activity. Consumer activity trackers have become increasingly popular today, such as the Fitbit. This study aimed to compare the average number of steps per day using the wrist-worn Fitbit Flex and waist-worn ActiGraph (wGT3X-BT) in free-living conditions. Methods: 104 adult participants (n = 35 ...


Reliability and validity of the French version of the global physical activity questionnaire

  • Published on Aug 15, 2016

Background: The Global Physical Activity Questionnaire (GPAQ) has been used to measure physical activity (PA) and sedentary time in France, but no study has assessed its psychometric properties. This study aimed to compare the reliability as well as criterion and concurrent validity of the French version of the GPAQ with ...


Does home equipment contribute to socioeconomic gradients in Australian children’s physical activity, sedentary time and screen time?

  • Published on Aug 5, 2016

Background: Activity behaviours (physical activity, sedentary time and screen time) have been linked to health outcomes in childhood. Furthermore, socioeconomic disparities have been observed in both children’s activity behaviours and health outcomes. Children’s physical home environments may play a role in these relationships. This study aimed to examine ...
