In the Spanish forum there is more information than here with some doctors explaining cases of use of ZS that are very interesting.
It would be great to have an english translation of that here
-
@halajos Yes indeed!
Check the YouTube channel of Luis del Aguila, he is a sport Dr. that uses ZS, you can use the automatic subtitles.

@cosme-costa Thanks a lot for your insights!
However, to me the meaning of this sentence is unclear: “To have a good starting data in general, the first 3/4 runs with ZS, the whole run, should be very easy, but eventually everything will align if you do not do that.”. Would you mind rephrasing?
Additionally, why do you state that one shouldn’t try to match ZS and HR? I’m under the impression that this is exactly what Suunto is doing in the second screenshot I provided (even suggesting to change your HR zones based on ZS data). I fully got the idea, that on one day my aerob threshold could be at 140 bpm, the next day it could be at 150 bpm (due to fatigue, stress, sleep quality, etc). However, comparing HR and ZS still makes a lot of sense to me.
And finally, green is Z1&2, not yellow. So when trying to stay in Z2, I need to be within green, do you agree? And as you identified correctly, it was a slow pace. However, in reality, me trying to do a Z2 endurance training run, I would most likely had to run even slower (at a HR of around 140, maybe 150), not faster;). You see, I‘m only starting to run, haha

@halajos use the EDGE Browser. It translates all websites in language you are set.

@VoiGAS Sorry, maybe I wasn’t clear enough, you have to stop and save the warm up. I guess a multisport should do too but as far as I know ZS distinguish among sports, so not the same values for biking than for running, I do not know if between running and trail running it consider them different sports.
Thank you, I’ll try it that way!

@tschogo green is z1&2 yellow z3&4 red z5
-
@Mountain yes exactly. I tried to (and did, according to ZS) stay mostly in Z2. Even though this can‘t be true with my HR sometimes well above 160 (and me only starting to run somewhat methodically, i.e I‘m not a trained runner). That‘s basically why I‘m (still) confused.
-
@tschogo that’s the point why ZoneSense doesn’t work.
-
@tschogo i don’t think thats „exactly“
. Your HR zones are fixed values, that may or may not correspond to your actual aerobic/anaerobic state for that day. What was „green“ last week, (when the weather was colder, you had no cold, had no alcohol the night before etc. ) could be yellow today, (when it‘s warmer, you had 3 beers the night before and your nose is running faster then your feet 
). Also your HR Max could be wrong etc. I could recommend to run with Zonesense and trust the process

@tschogo Heart rate doesn’t always correlate with ZoneSense. For example, sometimes I run in full sunlight—I’m in Brazil, and the sun is extremely intense. With a heart rate of 120, I can shift into the anaerobic yellow zone simply due to the heat. The algorithm takes many more factors into account than just heart rate.
-
@Mountain the algorithm does take into account only the heart rate variability (and does some crazy correlation based maths to it).
The rest is happening in your body, which reacts to different stressors (like heat, muscle fatigue etc). Zone sense is just looking at the result -
@Egika Exactly, and HRV is influenced by so many factors I never would have expected.
