@jussim i didnt got red zone while doing intervalls… Heart rate Zone 5 but zone sense says GREEN ??? Whats going on here?

@GiPFELKiND as far as I understand it, reacting on short intervalls is NOT what Zonesense is capable of and made for. It’s more suitable for longer „phases“.
Actually I would interpret it that way, that your interval workout was deemed aerobic as a whole and that you could increase intensity, if you want. Zonesense is not about HR measurement, Suunto says, but about Heart measurement, measuring the stress of the heart. And I think it makes sense, seeing that after your short intervals Zonesene tracks you moving into higher aerobic states.
There is a pretty good youtube video from Suunto, describing this.

@Mff73 I suspect what this is saying is that your heart doesn’t like it much when you run up and down mountains
The time you were at the top and when you were on the flat bit near the end it was much happier -

This is by far the easiest to digest explanation of the behavior I have seen. This makes perfect sense.

No it’s my turn to have questions about ZoneSense. Today I did a run that felt fairly easy and so my ZoneSense stayed mostly green and the graph in the App agrees with that:
If we look at the detected thresholds ZoneSense thought it is a bit lower today - I can live with that…
No second threshold - it was an easy run.
So far so good. If we take in consideration that I set my LT1 to 152 and ZoneSense even lowered that to 148, I wonder why ZoneSense agreed with easy, when I look at my real heart rate recordings:
It gives me 55% of the time above 152, so above 148…
If the data makes sense somehow, possibly the presentation in the app is not reflecting that?

@2b2bff You said it felt fairly easy and the ZS reflected that. I find ZS matches my RPE very well.

@Brad_Olwin said in ZoneSense:

yeah I get that, but what about that heart rate discrepancy?

@2b2bff Why is there a HR discrepancy? ZS is reporting effort in real time. HR Zones are set either from lab or field test and are good only on the hour/day you test. That is the power of ZS. HR zones will change depending on stress, sleep, caffeine, training,fatigue,etc
This is the reason to use ZS! It is not a tool to find HR zones but instead a tool to measure real time effort. I have not had enough time in VO2M to assess that transition but I know when I cross my LT as my breathing changes and ZS is showing that transition well.

Your “Measured” “Aerobic threshold” of 148 bpm for that day is just a bone thrown to our obsession with exactitude. I don’t know if it is an average for the whole exercise, or the very first instance of measurement (observe we don’t get the number on our watches), but it is supposed to detect (I’ve forgotten the used terminology) when our HRV-system goes: ‘Hmmm… This doesn’t look like rest anymore’ [i.e. LT1]. Overall, the Heart Rate can be seen as living its own life - think about Pulse Drift for example - while HRV and its associated hormones and chemicals live another. The two measurements can at times be very decoupled.
Let me offer a recent exercise of mine which illustrates the decoupling in stark detail. I’m not used to running much above easy LT1 sessions, so the slightly below LT2 Pace-based 8x3 minutes with 1 minute jogging rests was an ordeal. In fact, I had to cut it short at 7 times because I was completely knackered; at such an extent that I had to start walking as the Cool Down instead of doing a normal running end. The “Measured” “Aerobic threshold” for the day was 145 (lab-measured some years ago as 148) and the first screenshot below is just to show, with a marker, where HR is in step with that threshold at the beginning. 3 minute intervals are not enough for ZS to shine, but it shows the exhausting trend quite accurately. There’s a HR dropout of ca 1 minute at about minute 22 - hence the flat lines in both graphs:
The next two screenshots have the marker at almost the same time (hard to manoeuvre with a finger) with the colourised ZS and HR versions of the graphs. At that time I’m walking in the “Light aerobic” HR Zone with 106 bpm, but as ZS shows well and truly Anaerobic. I was exhausted:
In this instance there really is no sense in talking about an “Aerobic threshold” of 145 bpm
