Objective To describe levels of physical activity, sedentary time and adherence to Chief Medical Officers (CMO) physical activity guidelines among primary school-aged children across the UK using objective accelerometer-based measurements.
Design Nationally representative prospective cohort study.
Setting Children born across the UK, between 2000 and 2002.
Participants 6497 7-year-old to 8-year-old singleton children ...
Background To test for cross-sectional (at age 11) and longitudinal associations between objectively measured free-living physical activity (PA) and academic attainment in adolescents.Method Data from 4755 participants (45% male) with valid measurement of PA (total volume and intensity) by accelerometry at age 11 from the Avon Longitudinal Study of Parents and Children (ALSPAC) ...
Growing attention has lately been given to the importance of Vitamin D as a factor protecting people’s health. As an exploratory study, we investigated the relationship between physical activity, light level and individuals’ vitamin D status within an intervention promoting physical activity. Fourteen adults (age 49.2±8.0 yr.) underwent a short ...
Purpose To contrast the associations of objectively measured moderate-to-vigorous physical activity (MVPA) and total accelerometer counts with biomarkers in a representative sample of U.S. adults.
Methods Data from the 2003 - 2006 NHANES were used for this analysis. The sample included adults ≥ 20 y, not pregnant or lactating, who had self-reported PA ...
Purpose The purpose of this study was to test if moderate to vigorous physical activity (MVPA) in less than the recommended ≥10-minute bouts related to weight outcomes.
Design Secondary data analysis.
Setting Random sample from the U.S. civilian noninstitutionalized population included in the National Health and Nutrition Examination Survey (...
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 ...
Physical activity monitors can quantify various types of Physical Activities (PAs) in Manual Wheelchair Users (MWUs) with Spinal Cord Injury (SCI). The objective of this study was to develop new energy expenditure (EE) prediction models for MWUs with SCI based on an ActiGraph activity monitor. A total of 45 MWUs with ...
Background:
Research has indicated that actigraphy is valid and reliable for measuring low levels of physical activity among ambulatory individuals, and that it may be a valid indicator of energy expenditure for wheelchair users in laboratory conditions, but there are no reports of its evaluation in free-living conditions.
Objective:
To ...
Introduction:
Attention-Deficit Hyperactivity Disorder (ADHD) is the most common mental health problem in childhood and adolescence. Its diagnosis is commonly performed in a subjective manner since current objective measurements are either expensive or time-consuming. However, subjective methods tend to overestimate the severity of the pathology. In this paper, we propose ...
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 ...
