Introduction. Estimating energy expenditure (EE) related to outdoor walking capacity in peripheral artery disease (PAD) patients could allow a better standardization of the assessment of their limitations during free-living outdoor walking. However, there is no data regarding the accuracy of ambulatory methods to perform such estimations. Our aim was to ...
Introduction: Our research group has developed the processing of raw acceleration data to ActiGraph counts for improved assessment of high intensity physical activity. The aim of the present study was to apply this new processing method to large population data and investigate the effect on physical activity compared to the ...
Background: Accelerometers provide an objective assessment of physical activity and are frequently deployed for at least multiple days. However, it is unclear how to summarize multiple days into one overall physical activity estimate, particularly in the presence of missing data. This study compared summarization method prediction and precision, and the ...
Objective:
Examine the association between objectively-measured moderate-to-vigorous physical activity (MVPA) and engagement in self-reported muscle strengthening activities (MSA) with alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT), and in turn, how each of these parameters associate with of all-cause mortality.
Methods:
Data from the 2003–2006 NHANES were employed, with follow-up through December 31, 2011 (N = 5030; 20+ ...
Background: The implementation of physical activity interventions in centre-based childcare services has been recommended to improve child health. This study aims to evaluate the efficacy of scheduling multiple periods of outdoor free play in increasing the time children spend in moderate-to-vigorous physical activity (MVPA) during childcare.
Methods: The study will ...
Objectives: To examine the validity and reliability of the Fitbit Flex against direct observation for measuring steps in the laboratory and against the Actigraph for step counts in free-living conditions and for moderate-to-vigorous physical activity (MVPA) and activity energy expenditure (AEE) overall.
Methods: Twenty-five adults (12 females, 13 males) wore a Fitbit ...
Objective:
To investigate the effect of a seven-month, school-based cluster-randomized controlled trial on academic performance in 10-year-old children.
Methods:
In total, 1129 fifth-grade children from 57 elementary schools in Sogn og Fjordane County, Norway, were cluster-randomized by school either to the intervention group or to the control group. The children in the 28 ...
Background: This study investigates prospective associations of anthropometrical and lifestyle indices with insulin resistance (IR) in European children from the IDEFICS cohort. Insulin resistance (IR) is a growing concern in childhood obesity and a central aspect of the metabolic syndrome (MS). It most likely represents the link between obesity and ...
Objective: Household factors (electronic media equipment, play equipment, physical activity in the home, and social support) have been associated with childhood moderate- to vigorous-intensity physical activity (MVPA), but little is known about how these factors differ across diverse countries. The objective was to explore household correlates of objective MVPA in ...
Background: Activity trackers are increasingly popular with both consumers and researchers for monitoring activity and for promoting positive behavior change. However, there is a lack of research investigating the performance of these devices in free-living contexts, for which findings are likely to vary from studies conducted in well-controlled laboratory settings.
