Accelerometer: Assessing Physical Activity Dose for Health

The image above shows a detail of an accelerometer, a device that measures the amount and intensity of movement. Using wearable monitors to assess physical activity dose, UMass Amherst kinesiologists Catrine Tudor-LockePatty Freedson and colleagues (Public Health and Health Sciences) are using accelerometer-based data processing methods to accurately quantify the amount and intensity of physical activity to better understand the “dose” of activity that correlates to positive health outcomes. With new funding from NIH’s National Institute on Aging, Tudor-Locke is developing a common metric that can be collected and interpreted across the variety of pedometers, accelerometers and other wearable trackers now in use for personal activity level monitoring.
