Purpose: To assess the associations between 1) baseline objectively-measured activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) activity) and 4-year change in adiposity, and between 2) 4-year change in activity intensity and adiposity at follow-up.
Methods: Analyses of longitudinal data from the SPEEDY study, including all participants with valid data at ...
Purpose: To compare relations of neighborhood walkability and home equipment to (1) total and (2) location-specific physical activity.
Methods: 290 adolescents (M age=14.1±1.4 years; 45% girls; 74.7% White non-Hispanic) wore GPS and accelerometers for 5.4±1.9 days set to record at 30-second epochs. GIS was used to calculate a walkability index (sum of z-scores for density, mixed-use, ...
Purpose: Environmental characteristics of home neighbourhoods are hypothesised to be associated with residents’ physical activity levels, yet many studies report only weak associations. We propose this is in part a result of inappropriate definitions of what constitutes a neighbourhood. We objectively measured the distance that adolescents roamed from home to ...
Purpose: To examine whether change in SB and PA associated with a change in weight status over 24-months.
Methods: Data were from Identifying Determinants of Eating and Activity (IDEA), a 3-year longitudinal cohort study that assessed the etiology of adolescent obesity. PA and SB were assessed using the ActiGraph (Model 7164; ...
Background: Few randomized trials attempt to improve insulin sensitivity and associated metabolic risks in overweight youth, particularly Latino adolescents.
Purpose::The aims of the present pilot study are two-fold, (a) to test the efficacy of the intervention by comparing the home-based strength training (HBST) interventions vs. control group (C); ...
Purpose: Using static, ontogenetic and multilevel allometric modelling, objectives of the study were twofold: to estimate inter- and intra-individual effects of body size descriptors on the development of LVM in adolescent boys, and to examine independent and combined effects of physical activity (PA), sedentary time and biological maturity status on ...
Background: Autism spectrum disorders (ASD) is characterized by impairments in social interaction and communication skills and restrictive interests. ASD may also include delayed or impaired motor development. These social, behavioral, and perhaps motor impairments may interfere with a variety of physical activity (PA) opportunities, and therefore, put them into risk ...
Introduction: The on-going Finnish Schools on the Move programme aims to make the school day more physically active. This study investigated how school-time physical activity changed in students from grades 1 to 9 in two academic years during the pilot phase of the programme.
Methods: The data was collected in 2010-2012 during ...
Aim: The aim of this study was to assess time trends in objectively assessed physical activity in a population based sample of children and adolescents living in Norway.
Methods: The sample population (n=4766) consists of two independent samples of 9- and 15-year-old children recruited within the PANCS project in 2005-06 ...
Background: Multicomponent school-based interventions have the potential to reduce the age-related decline in adolescents‘ physical activity (PA). Studies on the effect of school environment interventions have reported varying results.
Purpose: To assess the effectiveness of a multicomponent environmental school-based intervention, designed to reduce the age-related decline in PA among adolescents.
