Evaluating variations in free-living energy expenditure during the day and on a day-to-day basis is of major interest in clinical trials as well as for individual use. Several monitors are available today for research on energy expenditure (EE) prediction.
The aim of our study was to compare the accuracy of EE estimation of two of these devices (Actiheart and Armband), compared to measurements using calorimetric chambers for the assessment of changes of energy expenditure during the day, and the doubly-labelled water (DLW) technique for the evaluation of free living total energy expenditure.


CAMNTECH NOTE: The Bodymedia Sensewear Armband has been discontinued since the sale of Bodymedia to the consumer company ‘Jawbone’ in 2013. Jawbone subsequently went into liquidation in 2017 and all product support was discontinued. This illustrates the danger of choosing consumer focussed products for scientific research. Our professional, research grade Actiheart device has been available and continually refined since 2003 with hundreds of peer-reviewed publications.
