Suunto ZoneSense

Christoph13

@stromdiddily Thanks. I am always weary of relying on a metric that I have insufficient experience with.
When you are racing, you want to be close to the special mark on your personal fitness scale on that day, but on the correct side. Looking at the handful of runs with Zone DDA data, it looks like I will be racing mostly in the yellow zone (in ZoneSense it is called anaerobic but I suspect what it means is that it is no longer fully aerobic, which is fine).
For the race this probably means to progress mainly through the yellow zone with some excursion into the red during the finish, however long that may be.

BTW, I am seeing some of the weird behaviour reported by others, too, i.e. pace or heart rate go up, ZoneDDA becomes more aerobic,…

I’ll see how the half marathon goes and then take a look at the data again.

Totally unusable for me!

@sartoric I would think not? the app is on the watch

@larrybbaker
The S+ app is used to have real time data while recording the activity

This is function is really good. Have now used Suuntosense 4 times and have nothing to complain.
But i don’t think this is for me since I always get the same results, even if I feel good or tired and therefore don’t see the point of using it right now

@Mauerwegler Link?

Haven’t done this myself, but you have to download the version you want and then drag‘n‘drop the file on the Suuntolink software on your computer.

@TrailEyes very nice article

Stefan Kersting

I would appreciate if one of you guys could help me interpreting my ZoneSense data. BTW a very interesting feature I want to understand more.

The first screenshot is from a spinning activity. 20 minutes warm up before weight lifting and I felt that I did an ordinary effort. Not to hard.
The second screenshot is from a spinning activity of 50 minutes with three intervals. I did an hard effort but it wasn’t a maximum effort. When I see the aerobic threshold here it is 152 bpm, actually the max of my zone 4. what does that mean? Have I to adjust my zones now?

So it is only with HR belt, it does not work with optical sensor on the watch ?

It should work with the Scosche Rhythm24 OHR, as long as you set it to measure HRV.

@Stefan-Kersting I have been wondering the same after my first run. Z2/Z3 limit proposed by zonesens is far lower in my case than the level i have in HR zones.
My thoughts so far : I won’t change my HR zone and see in next weeks months how zonesens will evolve. If have understood well it should need time for the algo to calibrate. And whatever it says, it is supposed to take more consideration of health condition. So when hill it should always propose different HR values than those set in SA.
So my final point is : my HR zone are probably “well set” when I’m fit and healthy. Zonesens should bring in time more indications about my real capacities of the day.

My 33% “good experience” with ZONESENSE.

(Suunto 9PP + PolarH10 heart belt / IOS App v2.38)

The last few days I have tried Zonesense three times with the following performance results:

Mountain bike. No route tracking. WATCH FAIL (*) / APP OK
Mountain bike. With route tracking. WATCH OK / APP OK
Trail running. With route tracking. WATCH OK / APP FAIL (**)

(*) On the watch, the zone sense screen only indicated zone 1, regardless of heart rate or effort level, without the zone gauge moving. Later, however, in the app, the different zones were identified with colors and the thresholds were marked, etc.

(**) On the watch, everything worked perfectly, as expected from the Suunto+, indicating the times in each zone, the gauge indicating the appropriate section, etc. But then nothing appeared in the app, as if nothing had been registered.

Anyway, a promising feature that hasn’t worked consistently for me yet. I’ll keep trying over the next few days.

I’ve seen it too - however, zones switched as expected, only the gauge didn’t move. I think it was after unpausing the watch?

Mmm, well, thinking about it, maybe the pauses have something to do with it.

In fact, the only activity that worked well (watch and app) was the one without a pause.

In the first one, the autopause was activated shortly after starting (I have autopause in this sport mode). And in the second one, I activated and deactivated the pause during a stop (in trail running I don’t have autopause activated).

I’ll keep an eye on this aspect, thanks.

@Łukasz-Szmigiel I also had issues with ZoneSense, and I also did pause. I explained here: https://forum.suunto.com/topic/11713/race-misbehaving-in-multiple-ways

I am seeing an issue in the APP where periodically the watch will record and display the ZoneSense screen perfectly but when I sync to the app the ZoneSense dropdown is not available. If I kill the app it then loads correctly allowing me to see the ZoneSense data and flip between other metrics. Latest iOS beta SA, Suunto Vertical Ti. Morpheus HR Strap.

I rather suspect you might be able to make it display something because the minimum condition “HRV input feed present” is satisfied but the data quality is bound to be orders of magnitude lower for optical beat-to-beat analysis compared to a chest strap based on electric impulse detection to make the analysis meaningless (Garbage in, garbage out).

That is not to say that the Scosche is a bad heart rate meter (I am using a Polar Verity Sense myself), I just would not trust HRV data coming from anything but a chest strap.

Stefan Kersting

would like to share my first observations her. Did some spinning workouts with 3x5 min intervals. when warming up I was in the aerobic zone. after starting a harder effort within the 5 min interval it took about 2 min to get into the anaerobic zone. After further 2 min i got into the Vo2 max zone. So one minute was left and even when still going string with a HR of 158 i dropped back into the aerobic zone. Have to give it som more tries and observe a little bit more.

@Stefan-Kersting How long were your recovery breaks? If they were short I think you saw the expected behaviour

Edit: Except the breakdown in the end…

Stefan Kersting

@VoiGAS recovery breaks were 5 min

@enriqueescoms I have similar experiences with my SV… 🥲 I use the Suunto smart heartrate belt
