ZoneSense

@2b2bff That is why there are 3 zones, green aerobic, yellow mixed aerobic/anaerobic and red anaerobic. No need to fixate on a single HR number. The number you get is the predicted for THAT workout.

@2b2bff I agree with the presentation as being suboptimal, but how to change it? On the one hand there is the oldish training philosophy with rather static HR Zones (3, 5, 7, 9 or whatever, depending on the specific seller of books and methods), on the other there is some newer attempts of a more dynamic view, like ZS, where HR in itself plays a less prominent role.
In the example you provided you obviously had a very good day, where the HR (post 20 some minutes) could average about 155 bpm without the Nervous System/Brain starting to pump too much Lactate into the blood stream. In my example exercise, which was designed to reach and keep Lactate at about 3 mmol/l in the main segment, the Nervous System/Brain put its foot of protection down at the end by forcing me to quit and walk, and at the same time refusing to clear Lactate even with a low HR.
How can these fluid situations be grafted unto a list of HR Zones and Thresholds? Perhaps they shouldn’t… Perhaps anything Zone Sense should be kept as a separate page with more elaborate explanations.

@Brad_Olwin if the number is predicted for THAT workout - and it keeps consitent throughout the workout, so why have I been below LT1 most of the time according to ZoneSense and at the same time I have been in Zone 3 - above LT1 - according to the HR measurement. Even though the ZoneSense LT1 is below what I configured as the starting HR of my Zone 3?
That was the whole point of my question…@Inge-Nallsson I honestly don’t know. Possibly Suunto should take out that screen that you get when touching (i) alltogether. The two graphs make sense to me. That other screen left me clueless…

@2b2bff I think I could make this clearer if we were speaking. You are assuming AT based on an HR measurement that is not valid. For example, my tested AT is 142 and the tests are not super accurate so let’s assume 140. Yesterday ZS gave me an AT of 128 so I could ask the same question. Why am I anaerobic when I should be aerobic based on ZS? (This is the opposite of yours).
It is because my AT was not 140 yesterday it was near 128 because of likely many factors, my training schedule, my fatigue, etc. If my AT was 148 instead of 140 according to ZS it would be because I was well rested and likely slept well and maybe in a recovery week. HR for AT is not a fixed value and will depend on many physiological factors. ZS provides a real-time estimate of AT.
