Suunto ZoneSense

[snorbie]

@gone-troppo have you managed to get Zonesense results on the app …I’m having the same trouble

[VoiGAS]

@FCDsh Any news about Rays results? I found nothing on his or the correraunmarathon webpage. Your info is from social media?

[Jan Suchánek]

Is there any chance, we can get ZS on Karoo bike computer?

[FCDsh]

@VoiGAS Not yet. Ray posted the photos on Instragram at the beginning of his ZoneSense test phase. Normally it takes a few weeks between extensive testing and publication of the results on dcrainmaker.com - so it’s quite possible that we won’t see anything here until December / January. Patience is required here - although I have to admit that the curiosity about the results is quite high!

App was updated yesterday. Can anyone spot any changes?

[herlas]

@jussim it can now be used at same time with S+ climb, both were updated. Sounds like it’s mostly optimizations I’d guess.

@jussim said in Suunto ZoneSense:

App was updated yesterday. Can anyone spot any changes?

You mean Android App, doesn´t it?

[cosme.costa]

@enriqueescoms ZoneSense and Climb apps, in the watch.

ZoneSense and Climb weren’t compatible using both at the same time. Now they are and some other improvements.

As I have read in the Spanish forum you have to uninstall both apps and reinstall them.

[jussim]

@enriqueescoms Sorry for not being clearer, I meant SuuntoPlus app ZoneSense.

[Bento Galado 0]

@cosme-costa any visibel improvement, or i just backoffice fix?

[enriqueescoms]

@cosme-costa Ah, ok, great! Is there anything I need to do or are both features updating themselves?

[cosme.costa]

@enriqueescoms As I understand bug fixes in both apps, I just have read in the Spanish Forum that ZoneSense is now more reactive in the watch.

I’m still puzzling over the ZoneSense results in the APP a bit, as the info seems slightly contradictory.

Example: Today I did a reasonably hard indoor rowing session where my heart rate was between 140 and 150 BPM for the last 22 minutes (of a 33 minute session), which normally equates to a Zone 4 HR session.

ZoneSense says that for this workout, my aerobic threshold is 131 bpm, and my anerobic threshold is 148 bpm. Surely then those 22 minutes should have been in the yellow zone, as anything above 148 bpm would have been VO2 max, and therefore red.

But it has the whole 22 minutes as green (I didn’t check it live on the watch whilst rowing… too busy rowing!).

My previous indoor rowing was similar. Again, I think it should be showing that 22min steady state as yellow as it is above the aerobic threshold and below the anaerobic threshold.

So what is going on?

[herlas]

S+ ZS got updated again (twice this week) looks like Suunto is actively working on this S+, which is a good sign.

[jussim]

@herlas I was going to report a weird thing I experienced on a morning run just the other day: the ZS screen stayed black & white the whole run. A random glitch or a bug that got fixed? We’ll see

[Tieutieu]

@herlas : does update automatically applies to the app or it needs to be reinstalled ?

[halajos]

@Swaddy61 ad ZoneSense makes is computations on the inter-beat (R-R) intervals of the heart to find patterns over a time window, if the heart rate is not steady enough for long enough (couple of minutes), then the result of all that math (a single derived number) can fall into the wrong bucket. I have experienced ZoneSense showing aerobic effort during uphill, when my HR was around my lactate threshold (top of Z4). In more steady state periods the result is much more plausible.
As any technology, ZS also has its limitations.

[herlas]

@Tieutieu it should but it’s recommended to uninstall, sync, make sure it’s gone from watch, then install again.

[Brad_Olwin]

Three examples working well for me:
First is 3 20 min Tempo Intervals. ZS was showing yellow for most of these on the watch and the app matches well. HR and ZS match up well.

For the other two I ran a fairly long RPE 5-6 3.5 h Trail Run on Saturday 07/12 where my AT was near the threshold that has been measured.

Today 08/12 a day after the longer and harder run I ran easier in mid Endurance RPE4-5. Unsurprisingly even though the run was easier my fatigue from yesterday was apparent as my AT was measured at 130 bpm. ZS for me is accurately measuring my RPE in almost all cases.

[herlas]

3rd time ZS+ gets a new update in the last week or so, it wasn’t working with Race Nutrition S+ app and that was fixed.
