Physical activity, sedentary time, and pericardial fat in healthy older adults

  • Published on Oct. 2012

Abstract: Pericardial fat is emerging as a unique risk factor for coronary disease. We examined the relationship between objectively measured physical activity during free-living and pericardial fat. Participants were 446 healthy men and women (mean age = 66 ± 6 years), without history or objective signs of cardiovascular disease (CVD), drawn from the Whitehall II ...


Effects of Substituting Sedentary Time with Physical Activity on Metabolic Risk

  • Published on March 28, 2014

Purpose: The detrimental effects of sedentary time on health may act by replacing time spent in physical activities. The aim of this study was to examine cross-sectional associations between objectively assessed sedentary and physical activity domains on cardiometabolic risk factors using a novel isotemporal substitution paradigm. Methods: Participants were 445 healthy ...


Participatory Workplace Interventions Can Reduce Sedentary Time for Office Workers—A Randomised Controlled Trial

  • Published on Nov. 12, 2013

Background: Occupational sedentary behaviour is an important contributor to overall sedentary risk. There is limited evidence for effective workplace interventions to reduce occupational sedentary time and increase light activity during work hours. The purpose of the study was to determine if participatory workplace interventions could reduce total sedentary time, sustained ...


Amount of Time Spent in Sedentary Behaviors in the United States, 2003–2004

  • Published on Feb. 25, 2008

Abstract: Sedentary behaviors are linked to adverse health outcomes, but the total amount of time spent in these behaviors in the United States has not been objectively quantified. The authors evaluated participants from the 2003–2004 National Health and Nutrition Examination Survey aged ≥6 years who wore an activity monitor for up to 7 ...


Do Activity Levels Increase After Total Hip and Knee Arthroplasty?

  • Published on Dec. 19, 2013

Background: People with osteoarthritis (OA) often are physically inactive. Surgical treatment including total hip arthroplasty or total knee arthroplasty can substantially improve pain, physical function, and quality of life. However, their impact on physical activity levels is less clear. Questions/Purposes: We used accelerometers to measure levels of physical activity ...


Validating two self-report physical activity measures in middle-aged adults completing a group exercise or home-based physical activity program

  • Published on Nov. 19, 2013

Objectives: To compare self-reported physical activity recorded in physical activity diaries or the Active Australia Survey with objectively measured physical activity using accelerometry in sedentary middle-aged adults completing two physical activity interventions. Design: Cross-sectional study Methods: Sedentary 50-65 year olds were recruited to a non-randomized 6-month community group exercise program (...


Reallocating time to sleep, sedentary behaviors, or active behaviors: associations with cardiovascular disease risk biomarkers, NHANES 2005-2006.

  • Published on Jan. 17, 2014

Abstract: Sleep and sedentary and active behaviors are linked to cardiovascular disease risk biomarkers, and across a 24-hour day, increasing time in 1 behavior requires decreasing time in another. We explored associations of reallocating time to sleep, sedentary behavior, or active behaviors with biomarkers. Data (n = 2,185 full sample; n = 923 fasting subanalyses) ...


Children’s sedentary behaviour: descriptive epidemiology and associations with objectively-measured sedentary time.

  • Published on Nov. 25, 2013

Background: Little is known regarding the patterning and socio-demographic distribution of multiple sedentary behaviours in children. The aims of this study were to: 1) describe the leisure-time sedentary behaviour of 9-10 year old British children, and 2) establish associations with objectively-measured sedentary time. Methods: Cross-sectional analysis in the SPEEDY study (Sport, Physical ...


Participatory workplace interventions can reduce sedentary time for office workers-a randomised controlled trial

  • Published on Nov. 12, 2013

Background: Occupational sedentary behaviour is an important contributor to overall sedentary risk. There is limited evidence for effective workplace interventions to reduce occupational sedentary time and increase light activity during work hours. The purpose of the study was to determine if participatory workplace interventions could reduce total sedentary time, sustained ...


Comparison of Objectively Measured and Self-reported Time Spent Sitting

  • Added on March 11, 2014

Abstract: Until recently, methods for objective quantification of sitting time have been lacking. The aim of this study was to validate self-reported measures against objectively measured total sitting time and longest continuous time with uninterrupted sitting during working hours, leisure time on workdays and leisuredays. Objective diurnal measurement of sitting ...
