Accuracy of a combined heart rate and motion sensor for assessing energy expenditure in free-living adults during a double-blind crossover caffeine trial using doubly labeled water as the reference method

Abstract

Ekelund, U., Sardinha, L. B. (2015). Accuracy of a combined heart rate and motion sensor for assessing energy expenditure in free-living adults during a double-blind crossover caffeine trial using doubly labeled water as the reference method. AbstractBackground/Objectives: A combined heart rate (HR) and motion sensor (Actiheart®) has been

Accuracy in Wrist-Worn, Sensor-Based Measurements of Heart Rate and Energy Expenditure in a Diverse Cohort

“…Since devices are continually being upgraded and algorithms tuned, we created a website for sharing validation data for the community and to provide a forum for users to interact with the most up-to-date performance evaluations from this ongoing study () [23,25,26,27,28]. While the FDA currently considers consumer wearable sensors such as wrist-worn devices as low risk (Class 1) and therefore not subject to active regulation, [29] they are however expected to increasingly inform clinical decision making.…”

Accuracy in wrist-worn, sensor-based measurements of heart rate and energy expenditure in a diverse cohort

“…14 Since devices are continually being upgraded and algorithms tuned, we created a website for sharing validation data for the community and to provide a forum for users to interact with the most up to date performance evaluations from this ongoing study (http://precision.stanford.edu/). 13,[15][16][17][18] While the FDA currently considers consumer wearable sensors such as wrist worn devices as low risk (Class 1) and therefore not subject to active regulation, 19 they are however expected to increasingly inform clinical decision making. This makes transparency regarding benefits and limitations of paramount importance.…”

How well do activity monitors estimate energy expenditure? A systematic review and meta-analysis of the validity of current technologies

“…Recent consumer devices include triaxial accelerometers, heat sensors and photoplethysmography heart rate sensors 13. This information can be incorporated to improve the estimation of EE relative to accelerometry alone 14. However, their accuracy compared with criterion measures is questionable15 and may vary with the type and intensity of activity 16…”
