Focused on the accelerometer-determined physical activity and sedentary time metrics in 9–11-year-old children, we sought to determine the following: (i) number of days that are necessary to achieve ...

To test the association between physical activity measured using accelerometer counts (Actigraph) and energy expenditure (EE) measured using the doubly labelled water (DLW) method in free-living ...

Objective This systematic review assessed the completeness of accelerometer reporting in physical activity (PA) intervention studies and assessed factors related to accelerometer reporting. Design The ...

Light intensity activities, like walking or household chores, were linked to a lower risk of death for people with ...

The technology in fitness trackers is changing the way researchers study exercise, allowing them to gather much more detailed information about how people move throughout the day, experts say. The ...

About The Study: In an analysis of 89,000 individuals providing a week of accelerometer-based physical activity data, a weekend warrior pattern of physical activity (i.e., most moderate to vigorous ...

High-tech fitness and activity trackers all share one thing: an accelerometer. Here’s how they work — and don’t. Accelerometers record changes in motion relative to the device: up and down, side to ...
