Waist circumference and cardiorespiratory fitness are independently associated with glucose tolerance and insulin resistance in obese women

  • Published on Dec. 12, 2013

Abstract: The purpose of this study was to determine the independent associations between physical activity (PA), cardiorespiratory fitness (CRF), abdominal obesity and insulin action in obese women. We studied 141 abdominally obese women (waist circumference (WC): 106.4 ± 10.2 cm). PA duration (min/day) and intensity (counts/min) were obtained by accelerometry. CRF was ...


Associations of Sedentary Behavior, Sedentary Bouts and Breaks in Sedentary Time with Cardiometabolic Risk in Children with a Family History of Obesity

  • Published on November 2013

Background Although reports in adults suggest that breaks in sedentary time are associated with reduced cardiometabolic risk, these findings have yet to be replicated in children. Purpose To investigate whether objectively measured sedentary behavior, sedentary bouts or breaks in sedentary time are independently associated with cardiometabolic risk in a cohort ...


Adiposity and Insufficient MVPA Predict Cardiometabolic Abnormalities in Adults

  • Published on Jan. 1, 2014

Objectives To compare the extent to which different combinations of objectively measured sedentary behavior (SB) and physical activity contribute to cardiometabolic health. Design and Methods A population representative sample of 5,268 individuals, aged 20-85 years, was included from the combined 2003-2006 NHANES datasets. Activity categories were created on the combined basis ...


Associations between obesity and physical activity in dogs: a preliminary investigation

  • Published on Oct. 9, 2013

Objectives To assess whether obesity has any association with objectively measured physical activity levels in dogs. Methods Thirty-nine dogs wore Actigraph GT3X accelerometers (Actigraph) for 7 consecutive days. Each dog was classified as ideal weight, overweight or obese using the 5-point body condition scoring system. Total volume of physical activity ...


Patterns of Sedentary Behavior and Weight Status Among Children

  • Published on Oct. 2, 2013

In order to make robust conclusions regarding the association between accelerometer-measured sedentary time and overweight and obesity among children, several gaps in the literature must be addressed. The purpose of this study was to examine associations between sedentary time, weekday sedentary time, weekend sedentary time, sedentary bouts, sedentary breaks, and ...


Increased physical activity improves aerobic fitness, but not functional walking capacity, in severely obese subjects participating in a lifestyle intervention

  • Published on November 2013

Objective To determine the relationship between change in physical activity level and change in directly measured maximal aerobic fitness in severely obese subjects participating in a 1-year lifestyle intervention, and to determine whether change in 6-min walk test (6 MWT) could be used as an indicator of change in aerobic fitness. ...


Short sleep duration is associated with increased obesity markers in European adolescents: effect of physical activity and dietary habits. The HELENA study

  • Published on July 26, 2011

Background Adequate sleep is a critical factor for adolescent’s health and health-related behaviors Objective (a) to describe sleep duration in European adolescents from nine countries, (b) to assess the association of short sleep duration with excess adiposity and (c) to elucidate if physical activity (PA), sedentary behaviors and/or ...



Association between accelerometer-measured physical activity intensities and sedentary time in 8-10 year old children

  • Published on 2013

Abstract This study examines the association between objectively-measured physical activity (PA) intensities and sedentary behaviour (SED) in a cohort of 532 children aged 8-10 y. PA and SED were assessed by accelerometer over 7-days. Television and computer/video-game use were self-reported. Associations between PA intensities and SED variables were assessed by ...


Insulin secretion and its association with physical activity, fitness and screen time in children

  • Published on Oct. 16, 2013

Objective To determine the independent associations of moderate to vigorous physical activity (MVPA), fitness, screen time, and adiposity with insulin secretion in children. Design and Methods Caucasian youth (n = 423/630), 8-10 years old, with at least one obese biological parent, were studied (QUALITY cohort). Insulin secretion was measured using HOMA2-%...
