Introduction Different types of accelerometers are available to assess physical activity (PA) patterns levels, and the choice about which to use depends on various factors: cost, physical characteristics (weight, size, and battery life), performance (number of axes, possible epochs, system of data transfer, recording duration, function of the epochs, and ...
Introduction Cardio-metabolic risk factors are becoming more prevalent in children and adolescents. A lack of moderate-to-vigorous intensity physical activity (MVPA) is an established determinant of cardio-metabolic risk factors in children and adolescents [1]. Less is known about the relationship between sedentary behavior and cardio-metabolic health. Therefore, the objective was to examine ...
Background
Increasingly the combination of GPS, GIS and accelerometry is being employed in research on physical activity and the environment. GPS has potential as an objective and accurate method of collecting data on journeys and places used that does not suffer some of the drawbacks of alternative methods. Several studies ...
Background
Large changes in physical activity (PA) can be observed among teenagers. The majority of 11 year olds in Denmark do meet the recommend level of PA; the majority of 15 year olds do not. The chances of not meeting the recommended level of PA as adults are strongly correlated with not ...
Background
Parks are an important attribute of the built environment and are known to be associated with psychological, social and physical health benefits, perhaps as a result of improved opportunities to engage in physical activity (PA). Parks may be more likely to influence PA if they are accessible and if ...
Background Positive associations between dog ownership and adult health outcomes have been observed, but research involving youth is lacking.
Purpose The purpose of this study was to assess the relationship of family dog ownership to adolescent physical activity.
Methods Data were collected on dog ownership in 618 adolescent/parent pairs between 9/2006 ...
The purpose of the present study was to systematically review published evidence on the reproducibility, validity, and feasibility of motion sensors used to assess physical activity in healthy children and adolescents (2-18 yr).
Method
A systematic literature search was performed in October 2004 in PubMed, Embase, and SpycINFO. The clinimetric quality ...
Purpose The Trial for Activity in Adolescent Girls (TAAG) is a multi-center group-randomized trial to reduce the usual decline in moderate to vigorous physical activity (MVPA) among middle-school girls. In group-randomized trials, the group-level intraclass correlation (ICC) has a strong inverse relationship to power and a good estimate of ICC ...
Discussion of physical fitness and its relationship with physical activity is more apparent in adults than in children and adolescents (Malina 1996). A large portion of the variability in physical fitness is not accounted by physical activity (Malina, 2001). This suggests that, among pediatric subjects, other factors are involved and need to ...
Background
It is unclear how moderate and vigorous intensities of physical activity (PA) are associated with cardiovascular fitness (CVF) and percentage of body fat (%BF) in adolescents.
Objective
We tested the hypothesis that vigorous PA, to a greater degree than moderate PA, would be associated with better CVF and lower %...
