Validity and Comparability of a Wrist-Worn Accelerometer in Children.
BACKGROUND: Wrist-worn accelerometers may provide an alternative to hip-worn monitors for assessing physical activity as they are easier to wear and may thus facilitate long-term recordings. The present study aimed at a) assessing the validity of the Actiwatch (wrist-worn) for estimating energy expenditure b) determine cut-off values for light, moderate and vigorous activities, c) studying the ...
متن کاملCalibration and Validation of a Wrist- and Hip-Worn Actigraph Accelerometer in 4-Year-Old Children
INTRODUCTION To determine time spent at different physical activity intensities, accelerometers need calibration. The aim of this study was to develop and cross-validate intensity thresholds for the Actigraph GT3X+ accelerometer for wrist and hip placement in four-year-old children. METHODS In total 30 children (49 months, SD 3.7) were recruited from five preschools in Stockholm. Equipped wit...
متن کاملComparison of wrist-worn Fitbit Flex and waist-worn ActiGraph for measuring steps in free-living adults
INTRODUCTION Accelerometers are commonly used to assess physical activity. Consumer activity trackers have become increasingly popular today, such as the Fitbit. This study aimed to compare the average number of steps per day using the wrist-worn Fitbit Flex and waist-worn ActiGraph (wGT3X-BT) in free-living conditions. METHODS 104 adult participants (n = 35 males; n = 69 females) were asked ...
متن کاملDoes a waist-worn ActiGraph accelerometer quantify community ambulation in persons with multiple sclerosis?
Accelerometry has been recognized as a method of objectively measuring community ambulation in persons with multiple sclerosis (MS). However, the assumption that walking itself serves as a major contributor to the accelerometer signal has yet to be tested. This study examined the assumption that community-based walking is a primary contributor to accelerometer output in MS. Ambulatory persons (...
متن کاملTechnical variability of the Vivago® wrist-worn accelerometer.
The aim was to assess the technical variability of a new wrist-worn accelerometer under controlled conditions with a shaker device and during normal daily physical activities (PAs). In the first experiment, 10 wrist-worn accelerometers (Vivago(®) Wellness, Paris, France) were attached to the shaker device. Variability was tested at five shaking frequencies (1.1, 2.1, 3.1, 4.1, and 10 Hz) for 10...
