Relationship of Meeting Physical Activity Guidelines and Quality Adjusted Life Years

  • Presented on Oct. 27, 2013

Background/Purpose Regular physical activity is associated with reduced chronic disease burden and mortality. Recognizing the importance of physical activity, there are US federal guidelines for adults that also include persons with arthritis. Improving physical activity may be key to improving overall public health and reducing health care spending. Quality ...


Factors Associated with Sedentary Lifestyle of Hospitalized Patients Not Restricted to Bed

  • Added on October 30, 2013

Introduction The prolonged length of stay on the bed is related to the development of musculoskeletal and respiratory disorders. Therefore, the investigation of the level of physical activity and to verifying which factors are associated with the physical activity level in hospitalized patients might be important for future strategies to ...


Intense physical activity is associated with cognitive performance in the elderly

  • Published on Nov. 20, 2012

Numerous studies have reported positive impacts of physical activity on cognitive function. However, the majority of these studies have utilised physical activity questionnaires or surveys, thus results may have been influenced by reporting biases. Through the objective measurement of routine levels of physical activity via actigraphy, we report a significant ...


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

  • Published on Aug. 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 (...



A Longitudinal Study Evaluating the Effect of Exacerbations on Physical Activity in Patients with COPD

  • Published on Sept. 20, 2013

Background Physical inactivity is common in stable COPD and independently predicts poor outcomes. Longitudinal assessments of physical activity in outpatients with COPD, covering periods of stability and exacerbations, have not been evaluated previously. Methods Patients with clinically-stable COPD and a history of 2 or more clinical exacerbations in the preceding 12 months ...


How active are our children? Findings from the Millennium Cohort Study

  • Published on Aug. 21, 2013

Objective To describe levels of physical activity, sedentary time and adherence to Chief Medical Officers (CMO) physical activity guidelines among primary school-aged children across the UK using objective accelerometer-based measurements. Design Nationally representative prospective cohort study. Setting Children born across the UK, between 2000 and 2002. Participants 6497 7-year-old to 8-year-old singleton children ...


Associations between objectively measured physical activity and academic attainment in adolescents from a UK cohort

  • Published on Oct. 22, 2013

Background To test for cross-sectional (at age 11) and longitudinal associations between objectively measured free-living physical activity (PA) and academic attainment in adolescents.Method Data from 4755 participants (45% male) with valid measurement of PA (total volume and intensity) by accelerometry at age 11 from the Avon Longitudinal Study of Parents and Children (ALSPAC) ...


Can Promotion of Outdoor Activities Impact People’s Vitamin D Levels?

  • Presented on Sept. 2013

Growing attention has lately been given to the importance of Vitamin D as a factor protecting people’s health. As an exploratory study, we investigated the relationship between physical activity, light level and individuals’ vitamin D status within an intervention promoting physical activity. Fourteen adults (age 49.2±8.0 yr.) underwent a short ...


Comparison Of Four "Time In Intensity" Physical Activity Indices As Predictors Of Cardiometabolic Health

  • Presented on June 17, 2013

Introduction Recent physical activity (PA) guidelines incorporate recognition of the greater health benefits from higher intensity PA, but still dichotomize intensity into moderate or vigorous categories. New ubiquitous wearable accelerometry enables the estimation of intensity along the continuum from moderate intensity upwards. Purpose To compare two versions of a MET-min ...
