Introduction In México, despite the important issue of obesity and overweight, little is known regarding the relationship of physical activity and their related health issues, especially in the adolescent population Purpose To evaluate in a group of sophomore high school students the amount of physical activity measured by accelerometry ...
Background: There is evidence to suggest that increasing physical activity (PA) improves academic achievement (AA) in children and that aerobic fitness is associated with both cognitive function and AA. However, it is not known how these variables are interrelated and analyses with adequate control for socioeconomic variables are needed. It ...
Purpose The purpose of this study was to compare physical activity (PA) and sedentary time (ST) in children that reside within city limits (WCL) and those that live outside city limits (OCL) in a rural environment. Methods Physical activity and ST were assessed for 7 days via accelerometers (ActiGraph GT3X+) ...
Background: The afterschool period holds promise for the promotion of physical activity, yet little is known about the importance of this period as children age. Purpose: To examine changes in physical activity of children aged 5–6 years and 10–12 years and their sedentary time in the afterschool period over 3 and 5 years, and ...
There is limited evidence on objectively measured physical activity from Africa. This study quantified physical activity by accelerometry in rural South African children at ages 7, 11, and 15 years. Total physical activity was generally high (mean accelerometer counts per minute ranged 485–1017 across the 3 groups), but moderate- to vigorous-intensity physical activity was low: &...
Purpose: This study developed and tested an algorithm to classify accelerometer data as walking or non-walking using either GPS or travel diary data within a large sample of adults under free-living conditions. Methods: Participants wore an accelerometer and a GPS unit, and concurrently completed a travel diary for 7 consecutive days. ...
Background Many children spend too much time screen-viewing (watching TV, surfing the internet and playing video games) and do not meet physical activity (PA) guidelines. Parents are important influences on children’s PA and screen-viewing (SV). There is a shortage of parent-focused interventions to change children’s PA and SV. ...
Purpose The study aimed to examine the associations between objectively measured sedentary time, breaks in sedentary time, moderate-to-vigorous physical activity (MVPA) and total physical activity with markers of cardiometabolic health in a population with known risk factors for type 2 diabetes mellitus. Methods This study reports data from two ongoing diabetes ...
Background Active commuting to/from school is an important source of physical activity that has been declining over the past years. Although it is an affordable and simple way of increasing physical activity levels it is still unclear whether it has enough potential to improve health. Therefore, the aim of ...
Background Despite overwhelming evidence of the health benefits of physical activity, most American youth are not meeting the 60 minutes per day recommendation for moderate- to vigorous-intensity physical activity (MVPA). Policy changes have the potential to bring about substantial increases in physical activity in youth, within school and community settings. Purpose ...
