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 ...
Introduction Sedentary behavior (SB) has been defined as any purposefully engaged activity that is mainly dominated by prolonged sitting with low energy expenditure (METs<1.5). Objective measures (e.g., accelerometer) has widely been used for monitoring SB in free-living settings; however, relatively little effort has been made to develop an ...
Background: This randomised controlled trial demonstrates the effectiveness of a value-based intervention program to encourage a physically more active lifestyle among physically inactive adults aged 30 to 50 years. The conceptual framework of the program is based on an innovative behavioural therapy called Acceptance and Commitment Therapy (ACT) that aims to increase ...
Purpose The 2010 physical activity (PA) guidelines for older adults in the UK include a target of 150 minutes of moderate or vigorous PA (MVPA)/week and recommend minimizing time spent being sedentary in extended periods. There are few large studies of objectively measured PA in the elderly which can estimate the ...
