Background Increasing understanding of environmental and social correlates of physical activity can inform environmental and policy changes that help create active communities for youth. An emerging body of research suggests that all youth may not have the same level of access to physical activity resources and this may explain socioeconomic ...
Background The local build environment is believed to play an important role in youth physical activity (PA) as their independent mobility is restricted. To be able to target interventions to promote PA among youth knowledge about objectively measured PA patterns is important. We would like to be able to answer ...
Introduction Sedentary behavior (SB) is directly associated with a greater risk of death from cardiovascular problems, cancer and all causes. Moreover, SB is directly associated with obesity in children. This study examined whether there was a significant seasonal variation in objectively measured SB in Portuguese youth across five months of ...
Introduction Knowing the degree of physical activity in a population group becomes the first step to address sport promotion policies to encourage a healthy lifestyle that may have impact on better living conditions. Traditionally, we have used questionnaires and log books to ascertain the practice of physical activities and sports. ...
The absence of comparative validity studies has prevented researchers from reaching consensus regarding the application of intensity-related accelerometer cut points for children and adolescents. Purpose This study aimed to evaluate the classification accuracy of five sets of independently developed ActiGraph cut points using energy expenditure, measured by indirect calorimetry, as ...
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 ...
