Validity and Reliability of Fitbit Flex for Step Count, Moderate to Vigorous Physical Activity and Activity Energy Expenditure
OBJECTIVES To examine the validity and reliability of the Fitbit Flex against direct observation for measuring steps in the laboratory and against the Actigraph for step counts in free-living conditions and for moderate-to-vigorous physical activity (MVPA) and activity energy expenditure (AEE) overall. METHODS Twenty-five adults (12 females, 13 males) wore a Fitbit Flex and an Actigraph GT3X+...
متن کاملComparison of two sets of accelerometer cut-off points for calculating moderate-to-vigorous physical activity in young children.
Accelerometers are becoming more widely used in the assessment of physical activity in children, and converting the output to min of moderate-to-vigorous physical activity (MVPA) requires the use of age-specific cut-off point definitions. However, numerous cut-off points are available among children, and different cutoff point definitions of MVPA have been used in different studies. Comparison ...
متن کاملAccelerometry cut points for physical activity in underserved African Americans
BACKGROUND Despite their increased use, no studies have examined the validity of Actical accelerometry cut points for moderate physical activity (PA) in underserved (low-income, high-crime), minority populations. The high rates of chronic disease and physical inactivity in these populations likely impact the measurement of PA. There is growing concern that traditionally defined cut points may b...
متن کاملSteps/day translation of the moderate-to-vigorous physical activity guideline for children and adolescents
BACKGROUND An evidence-based steps/day translation of U.S. federal guidelines for youth to engage in ≥60 minutes/day of moderate-to-vigorous physical activity (MVPA) would help health researchers, practitioners, and lay professionals charged with increasing youth's physical activity (PA). The purpose of this study was to determine the number of free-living steps/day (both raw and adjusted to a ...
متن کاملThe contribution of recess to children's school-day physical activity.
BACKGROUND Recess is an important component of a Comprehensive School Physical Activity Program, providing approximately 1268 and 914 steps for boys and girls, respectively, within a 15-minute time period. The purpose of this study was to determine the contribution of unstructured recess on children's school-day physical activity levels and to examine if recess and school-day physical activity ...
