Energy expenditure is an important parameter during the performance of physical activity. An algorithm is presented calculating the burnt calories by three given parameters: heart rate, respiration rate and movement. These three vital parameters are provided by the FitnessSHIRT system which was developed by the Fraunhofer IIS. A study was performed to compare the calculated values of the energy expenditure with a reference system based on ergospirometry, an on-body monitoring system and two commercially available activity trackers. Compared to the reference system the developed algorithm, based on the parameters derived by the FitnessSHIRT, reaches a deviation of 18.0 % during running and 18.9 % during cycling.
