Objective To describe the associations among moderate-to-vigorous physical activity (MVPA), fitness, sedentary behavior (SB), and insulin sensitivity (IS).
Research Designs & Methods Data were drawn from the baseline assessment of the QUALITY cohort, which included 630 white youth (aged 8–10 years at recruitment), with at least one obese biological parent. IS was ...
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 ...
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 (...
Background There is currently no validated questionnaire available to assess total sedentary time in older adults. Most studies only used TV viewing time as an indicator of sedentary time. The first aim of our study was to investigate the self-reported time spent by older persons on a set of sedentary ...
Objectives:
The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body.
Methods:
Twenty participants (age=40.03 years, weight=75.8 kg and height=1.76 ...
Objective:
Examine the association between sedentary behavior and psychiatric symptoms among overweight and obese adults with schizophrenia or schizoaffective disorders (SZO/SA).
Design:
Randomized clinical trial; Weight Assessment and Intervention in Schizophrenia Treatment (WAIST) Study: baseline data collected 2005-2008.
Setting:
University of Pittsburgh Medical Center, Pittsburgh, PA, USA.
Participants:
Community-dwelling ...
Introduction:
Elevated C-reactive protein (CRP) is associated with adverse pregnancy outcomes. In non-pregnant populations, physical activity has been inversely associated with CRP, but this association has not been evaluated during pregnancy. The purpose of this study was to evaluate the association between objectively measured physical activity, sedentary behavior, and CRP ...
Background:
Physical activity (PA) and related energy
expenditure (EE) is often assessed by means of a single
technique. Because of inherent limitations, single techniques
may not allow for an accurate assessment both PA and related
EE. The aim of this study was to develop a model to accurately
assess common ...
Purpose Understanding fluctuations in lifestyle indicators is important to identify relevant time periods to intervene in order to promote a healthy lifestyle; however, objective assessment of multiple lifestyle indicators has never been done using a repeated-measures design. The primary aim was, therefore, to examine between-season and within-week variation in physical ...
Introduction Given its associations with morbidity and mortality, sedentary behaviour (SB) has emerged as a potentially significant public health issue. Although most studies of relationships between SB and health outcomes acknowledge that some sort of adjustment should be made for physical activity, there is no consensus on the approach for ...
