This Datafield calculates your training load based on your heart activity. The HRSS depends on exercise duration and intensity. The HRSS is based on an exponential scaling factor equation. </p><p></p><p>The HRSS code is according to the web extension Elevate (former Name: Stravistix): http://thomaschampagne.github.io/elevate/</p><p>According to Stravistix, HRSS is more accurate than the Training Impulse TRIMP since it takes care of the user Lactate Threshold Heart Rate (LTHR). LTHR is the best average heart rate that an athlete can maintain for up to an hour. Training one hour at the LTHR results in an HRSS of 100.</p>
