Training sessions recorded with an ECG heart rate sensor include  downloadable RR interval data (ie. the intervals between successive heartbeats). The data can be exported as a CSV file from the Training analysis page in the Flow web service and analyzed with various tools to calculate heart rate variability (HRV) metrics.

Please note that the RR data export is not available in the following cases:

  • Training sessions are performed with the Polar Flow or Beat app even if the sessions were done using an ECG heart rate sensor.
  • Training sessions recorded to the internal memory of H10 are processed in the Polar Beat app.
  • When an optical heart rate sensor is used as the heart rate source.
