Abstract
Introduction Access to raw acceleration data should facilitate comparisons between accelerometer outputs regardless of monitor brand. Purpose To evaluate the accuracy of posture classification using the Sedentary Sphere in data from two widely used wrist-worn triaxial accelerometers. Methods Laboratory: Thirty-four adults wore a GENEActiv and an ActiGraph GT3X+ on their nondominant wrist while performing four lying, seven sitting, and five upright activities. Free-living: The same participants wore both accelerometers on their nondominant wrist and an activPAL3 on their right thigh during waking hours for 2 d. Results Laboratory: Using the Sedentary Sphere with 15-s epoch GENEActiv data, sed..
