low aerobic and high aerobic work error

good morning. I did a low intensity workout. the heartbeats were in zone 2. so bland work of slow running. yet the training effect gave me "TIME". why? is a mistake? in training load it should have been low aerobic instead it gave me high aerobics. does anyone know the reason?

I'm not sure if it will stick to the zones you set. It will analyse your fitness and then categorize your workout accordingly.

The correct translation of Tempo in your case would be Pace. I think it is quite misleading as for you the word time is used in both senses...

It means your zones are setup differently than what firstbeat thinks are your zones. Maybe you should do a Aerobic Threshold Test and find out at what heart-rate your AeT is, then you know the divider between low aerobic and high aerobic.

Testing the Aerobic Threshold to find the divider between Zones 2 and 3, e.g. if you can run for 10min+ with a pulse of 140bpm breathing only through your nose but when you go to 145bpm you feel like you need to breathe through your mouth, then your Z2 upper limit is ~140.
