Aerobic Decoupling - %HRR vs %6min MMP/Pace

The relation between %HRR and %6min MMP/Pace is a good indicator for aerobic decoupling for training session. Checkout Stephen Seilers YT-video on "Long, low intensity endurance sessions". The decoupling ratio is calculated along a rolling window of about ten minutes. Generally, if it rises above 1.3, you should think about intensity and duration of the current activity if it was planned as LIT. Make sure to configure your individual 6min maximal Power or Pace values together with heart rate min and max values via the Garmin Connect App before using the data field.
