Suunto ZoneSense
-
@Stephen-Kenny @Sportsfreund
I used today’s run to look a bit closer. The watch said about 08:30 in yellow. The App on my iPhone says 10:00 yellow and interestingly the App on my iPad says 13:00 in yellow.But Suunto emphasizes in their videos that it is still early days, and they are going to improve it.

@stromdiddily so if you are suggesting that the app aligns with ten real time data you were shown on the app it may be that zonesense is aligned in real longer distances(??) . I am not there and I am running shorter ones .
In my case I have significantly different values between the watch and the app. I mean that in the watch I may have 15% of the time being on vo2max and the app to show 0%How long have you been using it? There is allegedly some calibration with each run used to make the real time data a bit smarter.

I am mostly running with an HR belt so I would say that I m using since it was announced .

Hi there!
Can you confirm for zonesense to properly work, you first need to put in some (how many?) workouts or minutes (which of both?) at each of the 5 zones? And basically ignore zonesense during this calbration workout(s)?
I’m asking as today I was running a 10k (probably my 3 workout with a HR belt and zonesense enabled) and wanted to do it in zone 2, but (almost) regardless of what HR I ran at, the DDFA-index stayed green:
On the other hand, it seems that zonesense was able to calculated my aet correctly, still:
This is a bit confusing to me. Any help is much appreciated, thanks!

@tschogo Theoretically you should always do the first 10 minutes easy, to do a proper calibration on each run. 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.
In case of a race, you have two options:
1.- Do an easy warm up for more than 10 minutes and stop the activity, then do the race. ZS will use the warm up as a base.
2.- Only record the race, here ZS will use the last good calibration, from your previous runs/activities.On each option the 10 first minutes will be discarded, option 1 should be more realistic because uses the base of the race day.
Regarding your 10 km, I understand that you wanted to do it in ZS zone 2 (yellow), I do not you as a runner and your paces, but from what I see it was a slow pace (1:20 for 10 km), so you should push a little bit more to enter in yellow. If we get used at some easy paces some times it is difficult go over this paces and we must also train these quick/effort paces, like starting doing short fast intervals or longer and progressive intervals with short rest times.
BTW do not try to match ZS and HR.
-
@cosme-costa But with Option1 you get a mix of warmup and Race Data. Would it be possible to switch from warmup to running with a multisport mode? Or would it start collecting data again after switching,
-
@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.
I’m not an expert but I have read a lot here and in the Spanish forum where all these things has been commented, and also my own experience.
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

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.
-
@Mountain Same here. Can’t run nearly HFmax and ZoneSense shows me green. Nonsens at this time. ZoneSense isn’t really work at this moment.
