Validity Of Wearable Activity Monitors For Estimation Of Resting Energy Expenditure In Adults, Zachary Motz, Yang Bail, Youngwon Kim, Danae M. Dinkel, Jung-Min Lee

Research Presentations

• Wearable accelerometers have become the standard method for assessing physical activity for both individuals and field-based research [1]. These new devices allow consumers to have the ability to estimate total energy expenditure and track it over time. • Resting Energy Expenditure plays a critical role in estimating daily total energy expenditure as it contributes 60-70% of total energy expenditure [2,3]. • Little to no information is available to substantiate the validity of these consumer-based activity monitors under free-living conditions.

Wearable activity trackers have become popular for tracking individual’s daily physical activity, but little or no information is available to substantiate the validity of these devices in step counts. PURPOSE: The purpose of this study was to systemically examine the validity of newly developed wearable activity trackers for measuring steps compared to the criterion measure (hand tally) in two different conditions. METHODS: Twenty (28.2±4.8 years) healthy males (n=19) and females (n=17) participated in the study. The participants were fitted with eight wearable activity trackers while walking and running on a treadmill (speeds of 2, 2.5, 3, 3.5, 4, …

PURPOSE: To evaluate the validity of wearable activity monitors in SPT and EE under free-living environment.

PURPOSE: To evaluate the validity of wearable activity monitors in SPT and EEunder free-living environment. METHODS: Thirty-nine (24.9+5.4 years) healthymales (n=26) and females (n=11) participated in this study. Total SPT and EE weremeasured by eight monitors; Nike+Fuel Band SE (NFB), Garmin VivoFit (VF), MisfitShine (MF), Fitbit Flex (FF), Jawbone UP (JU), Basis B1 (BB1), Polar Loop (PL), andSense Wear Armband Mini (SWA). The monitors were worn for at least 23 hours to beincluded in final data analysis and no PA restriction was applied. The …
