Purpose The purpose of this study was to examine the use of the ActivPAL (AP) and ActiGraph GT3X (AG) for estimating SB during structured and free-living physical activity (PA) in youth. Methods Twenty-nine boys and 23 girls (mean±SD; age, 12±0.9 yrs; BMI 23.3±5.8 kg.m-2) performed up to 8 structured activities and ...
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+) ...
Active video games or “exergames” (EG) may provide an effective method by which to increase physical activity (PA) levels of sedentary individuals although the energy cost is less than the real version of the sport or activities. However, if already active individuals increased their usage of EG, a resultant displacement ...
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 ...
Accelerometers are gaining popularity as an objective measure of sedentary behaviour. Limited evidence exists however on the validity of different cut points used to define sedentary time, or on the inclinometer function seen in newer models of the ActiGraph accelerometer. Purpose: To determine the concurrent validity of the ActiGraph GT3...
PURPOSE: To determine the relationships between objectively measured and self-reported physical activity, sedentary behavior, and academic performance in Finnish children. METHODS: Two hundred seventy-seven children from five schools in the Jyvaskyla school district in Finland (58% of the 475 eligible students; mean age 12.2 years; 56% girls) participated in the study in the spring ...
Purpose. To examine the accuracy of intensity and inclinometer output of three physical activity monitors during various sedentary and light-intensity activities. Methods. Thirty-six participants wore three physical activity monitors (ActiGraph GT1M, ActiGraph GT3X+, and StepWatch) while completing sedentary (lying, sitting watching television, sitting using computer, and standing still) ...
Physical activity and sedentary behaviour among children should be measured accurately in order to investigate their relationship with health. Accelerometry provides objective and accurate measurement of body movement, which can be converted to meaningful behavioural outcomes. The aim of this study was to evaluate the best evidence for the decisions ...
OBJECTIVE: With the rise of type 2 diabetes in youth, it is critical to investigate factors such as physical activity (PA) and time spent sedentary that may be contributing to this public health problem. This article describes PA and sedentary time in a large cohort of youth with type 2 diabetes and ...
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 ...
