High Aerobic always remains zero

4152815 3 days ago

Hi,

In my past trainings I had always some low aerobic trainings and some high aerobic trainings. I was using the Edge 840 with hear rate sensor. Since some weeks I'm using my new Garmin forerunner 970 to broadcast the heart rate and I Garmin Conncect tells me I have an high aerobic shortage. It actually is zero even when I was in zone 3 and 4 for some time. Heart rate zones seems fine on Edge and Forerunner. See a lot of topics on this issue on the forum but no solution. Any help is appreciated. Thanks

Could you post a link to one of your activities that you believe should trigger some high aerobic effect?

The most common reasons are inaccurate Max HR, LTHR, or Resting HR values, or the misunderstanding which exercise does actually trigger a high aerobic effect. A table with examples is available at What Is the Training Effect Feature on My Garmin Device? | Garmin Customer Support

This activity is labeled "Base", hence the training effect is indeed correctly considered "Low Aerobic". For "High Aerobic" effect, you have to be closer to the lactate threshold (Z4). See the table I mentioned previously, for some examples.
