Validity of Consumer-Based Physical Activity Monitors for Specific Activity Types

Abstract

Consumer-based PA monitors should be used cautiously for estimating EE, although they provide accurate measures of steps for structured ambulatory activity, similar to validated pedometers.

Comparison of four Fitbit and Jawbone activity monitors with a research-grade ActiGraph accelerometer for estimating physical activity and energy expenditure

“…This study only assessed the total measurement values for steps, EE, and active minutes over the observed period for all monitors assessed, and therefore time-matched analyses for each activity performed are not provided in current results. However, this analysis can be found in a similar study from our laboratory 15. The current study defined a step as lifting the entire foot and then placing it on the ground, which may not be the same method as the PA monitors use to recognise a step.…”

Energy Expenditure in People with Diabetes Mellitus: A Review

“…Accelerometry showed higher error particularly during low intensity activities and cycling (99, 105, 106). In order to overcome this limitation, Bonomi et al (107) demonstrated that the AEE estimate via accelerometry can be improved if it is combined with detection of the type of activity.…”

Risky Gadgets to the Rescue - Reframing In-Car Technology Use as Task Engagement

“…Our observations regarding varying HR data echo findings from a recent study by Nelson et al (2016) who examined the accuracy of various FitBit and Jawbone devices for 45 46 estimating energy expenditure (EE) and step counts. They found that consumer based 45 fitbit.com 46 jawbone.com/up physical activity monitors should be used cautiously for estimating EE, although they provide accurate measures of steps for structured ambulatory activity.…”
