This document presents a method for heart beat (R-R) based estimation of energy expenditure. This methods applies a wide range of heart beat derived physiological functions that provides increased accuracy and is yet very simple to use.
Firstbeat Technologies has developed a novel EE estimation method that is also based on heart rate information. This method is based on analysis of beat- by-beat heart rate data. The aim of this method has been to resolve the problems that cause errors in traditional EE-estimates.
