Recovery, HRV (Heart Rate Variability)

Heart Rate Variability (HRV) is a measure of the variation in time between heartbeats and its value is a good predictor of overall health and well-being.

HRV Recovery

HRV helps you to understand your recovery state and it measures your physical and mental stress and implies how ready your body is to train.

To be able to get an effective average HRV, you need to track your sleep at least three times a week over a longer period to establish your HRV range.

Different situations and conditions such as a relaxed holiday, physical and mental exertion or developing flu can lead to changes in HRV.


Please refer to or Suunto app to learn more about HRV recovery.
