Calculate Activity Energy Expenditure (AEE)
Measuring activity energy expenditure
with the Actiheart
The Actiheart is a compact, chest-worn device that records heart rate and physical activity in one combined, light-weight waterproof unit and uses a system of branched modelling to use both the activity and heart rate to calculate Activity Energy Expenditure (AEE).
How does it work?
The Actiheart simultaneously records activity and heart rate and uses both parameters to calculate Activity Energy Ex- penditure (AEE). By combining both activity and heart rate, the accuracy of the energy expenditure calculation is subs- tantially improved over using just activity or just heart rate alone. Energy Expenditure calculations are within 0.02kJ/kg/ min of those measured by a Cosmed K4b23
