Suunto ZoneSense

How much time do I need to be in a zone, that the respective threshold is shown afterwards in the app?
It seems 4 Minutes is not enough.

@Stoke80 In my experience, there is no simple rule. Currently I mostly row on an erg or commute by bike. In rowing I had activities where 2 minutes were enough. But that was an sustained sub threshold effort followed by a ramp test. Never did an FTP Test on a bike. But I got an estimate when doing fun repeats across a bridge that crosses an express way. Those repeats were shorter than 2 minutes but in sum they resulted in feeling very tired. Both thresholds are different by approx. 20 beats when comparing cycling to rowing in my case. But quite stable within the same kind of sport. Did you try a ramp test or a longer sustained effort that pushed you to your limit already?

@Stoke80 I’ve not analysed in detail but my gut feeling is ZS needs to ‘see’ a clear change in the RR data so blasting through into VO2max for a couple of minutes and hitting max hr would likely work but so would multiple ‘dips’ over into VO2Max and back into threshold. I mostly get LT2 (Zone 4 -> Zone 5) recommendations from ZS when I run threshold runs where my HR is dancing either side of LT2 (as I go up and down hills) and I sometimes get a recommendation when I over-cook the last step in a progression run. In the same way, I mostly get LT1 (zone2 -> zone3) recommendations when I do threshold intervals of a few mins with recovery of about 2 mins as my HR has time to drop back down to Zone 2 or Zone 1. Basically, the more your HR crosses the LT1 and LT2 thresholds within a workout (with enough time between that ZS can track it - so HIIT doesn’t work) the better it seems able to recommend zone settings.

@taziden or may be add the ability to choose permanently zone sense as intensity zones? alongside Pace and Power Zones?
If not yet proposed -
@fluca I don’t think that’s possible while ZS is still a SuuntoPlus app. But once the technology is stable, proven and not being developed as quickly I suspect it will be integrated directly into the watch firmware and then it would be a great option. While it’s still being developed quickly it’s much better to stick with it being an app because then the developers aren’t limited to the release cadence of the watch firmware

@Brad_Olwin have you had a chance to check?

5 Months testing Zone Sense. He found inconsistencies in data and several other issues…
It’s in Spanish, but maybe you can translate the text to your native language using any online translator.

@Luis-Andés-Olmedo the interesting piece is that he connected two Suunto watches to the same Polar H10 and they gave different ZoneSense data what completely defers the point of using it…

@Luis-Andés-Olmedo I think, we will see soon a DC Rainmaker version in English. I watched the video, it’s a huge disappointment. Useless random number generator at least for the tester. Very sad.
-
@Jan-Suchánek Rays test was a long time ago - I would say it would have been published already if all the participants would have agreed to do so…
Edit: It was November 2024 https://bsky.app/profile/dcrainmaker.com/post/3lbaymc64fk25

@VoiGAS You may be right. Eduardo (who runs a marathon) provides information in his analysis about a “recent” test, nothing about it having been performed in November. It’s perfectly clear that Ray is the third person to take the same test, and that’s why we can draw any conclusions.
A few days later, Eduardo released a video with “clarifications” about possible confusions in the previous video.

Waiting for possible reactions or Ray’s knowledge of his personal analysis… in short, as far as my use of ZS is concerned, it is a tool more focused on RESISTANCE, ULTRAS… and above all, very personal for controlling your RPE with your device… -
@2b2bff The belts will only send R-R data to one watch even if they connect to multiple watches. So how can one do the test? Have to wear two belts because no two tests can be identical.

@Brad_Olwin I have not read the article, but the Polar H10 has two separate Bluetooth channels (only one enabled as default) plus the ANT+. It would be utterly strange if the R-R only went through one BT channel…
-
@Brad_Olwin ant + being a broadcast communication, any number of watch can “connect” to the strap at the same time, unless r-r data is just sent over bluetooth ? That would bé weird
-
@Brad_Olwin I have an HRM Dual that I use with the Race S (BT) and the Epix Pro (ANT+) same time. Both receive R-R data. In fact I tried Alpha-HRV data field on my Epix today to see if I can make any sense of it compared to ZoneSense…
My feeling is that the H10 will send R-R over both BT channels. Otherwise ZoneSense would refuse to work, wouldn’t it?
-
@2b2bff My HRm_Pro his 3 channels but only sends RR on one. Maybe H-10 is different.

@Brad_Olwin said in Suunto ZoneSense:
@2b2bff My HRm_Pro his 3 channels but only sends RR on one. Maybe H-10 is different.
Does the HRM_Pro differentiate the channels so one knows which has RR? For the Polar H10, connecting it to two devices there’s no difference in how the two channels appear that I can tell.
The Wahoo TRACKR has three bluetooth channels and claims to provide HRV with compatible apps. From my review of their tech specs, it does not say there’s a difference in those channels either.

@Brad_Olwin as I said HRM Dual sends via BT and ANT+ same time…
I just read that on an article on alphaHRV that a Polar H10 or a Suunto Belt is preferred for good quality data…
https://aiendurance.com/blog/real-time-readiness-with-alphahrv-and-ai-enduranceThat said, my alphaHRV values have been completely off. Judging from those values I ran around LT2 with about 150bpm. ZoneSense showed be short dips into yellow for that run, what is more likely, as my LT2 is usually above 170bpm.
-
The Garmin Pro and Pro Plus, in addition to ANT+, can send three BLE signals. Here’s the comparison chart from Garmin:
What I don’t see is any indication that those three BLE signals differ in any way. I’m curious about the claim from Brad that only one bluetooth channel can send the appropriate data, as I see no indication of that in Garmin’s comparison. Also, if true, I’d like to know if that deficit also affects the Wahoo HRM.
