Validity Of Wearable Fitness Trackers On Sleep Measure, Alyssa Keill
Validity Of Wearable Fitness Trackers On Sleep Measure, Alyssa Keill
Research Presentations
Wearable trackers that detect sleep offer users a way to track their sleep quality and patterns without the use of expensive equipment. Few studies have tested the validity of these trackers on sleep measure. PURPOSE: To examine the validity of the Actigraph GT9X (AG), SenseWear Mini Armband (SW), Basis Peak (BP), Fitbit Charge HR (FB), Jawbone UP3 (JU), and Garmin Vivosmart (GV) for estimating sleep variables as compared with a sleep diary. METHODS: 78 healthy individuals participated in the study. Group 1 (n= 38) and wore the AG, SW, BP, and FB or Group 2 (n = 40) …
Examining The Validity Of Fitbit Charge Hr Tm For Measuring Heart Rate In Free-Living Conditions, Jung-Min Lee, Hyun-Sung An, Seoung-Ki Kang, Youngdeok Kim
Examining The Validity Of Fitbit Charge Hr Tm For Measuring Heart Rate In Free-Living Conditions, Jung-Min Lee, Hyun-Sung An, Seoung-Ki Kang, Youngdeok Kim
Research Presentations
Optical blood flow sensors (i.e. photoplethysmographic techniques) have recently been utilized in wearable activity trackers. The Fitbit Charge HRTM (FBHR) is one of the widely recognized wearable activity trackers that utilizes Fitbit’s proprietary PurePulse optical heart rate (HR) technology to automatically measure wrist-based HR. Despite its increasing popularity, however, no study to date has addressed the validity of FBHR for measuring HR in free-living conditions. PURPOSE: The purpose of this study was to examine the validity of FBHR for measuring HR using a chest strap Polar HR monitor (PHR) as a reference measure in free-living conditions. METHODS: Ten …

PURPOSE: Validate the Schoche (SC) (RhythmTM), Basis B1 Band (BB) (BASIS Science, Inc.), and Mio Alpha (MA) (Physical Enterprises, Inc.) wireless heart rate monitors. METHODS: Fifteen college students (males, n=11, age=27±5yrs; females, n=4, age=27±6yrs) participated. All participants simultaneously wore the SC on left forearm, the BB on the right wrist, the MA on the left wrist, and Polar HR strap on their chest. Participants’ resting heart rate was measured twice prior to exercise. The exercise protocol consisted of one 30-minute bout of continuous walking and running in which the treadmill speed increased every 5-minutes. The treadmill started at 2 …
Validity Of The Ihealth-Bp7 And Withings-Bp800 Self Measurement Blood Pressure Monitor, Hyun-Sung An, Matthew Bubak, Danae M. Dinkel, Dustin Slivka, Jung-Min Lee
Validity Of The Ihealth-Bp7 And Withings-Bp800 Self Measurement Blood Pressure Monitor, Hyun-Sung An, Matthew Bubak, Danae M. Dinkel, Dustin Slivka, Jung-Min Lee
Research Presentations
PURPOSE: The purpose of this study is to validate the iHealth-BP7 and Withings-BP800 monitors according to the European Society of Hypertension (ESH) International Protocol revision 2010. METHODS: Data from 11 participants (31.6 ± 2.2 years) were initially examined according to the ESH International Protocol for the validation of BP measuring devices. Participants were asked to sit and relax for 10-15 mins with legs uncrossed, and back supported prior to the test. In all participants, sequential left arm measurements were performed by two trained observers using a mercury sphygmomanometer and one supervisor using the device. Collected data were screened …
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
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.

How Accurate Are Wearable Activity Trackers For Measuring Steps?, Jung-Min Lee, Gregory Jones, Hyun-Sung An, Jungyoon Kim, Danae M. Dinkel
Research Presentations
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 …
