@PetrMisek But if you look, the graph perfectly shows the problem. One could think, not knowing, that you slept from midnight until 5 PM the next day. It is not helpful at all. Also, why does the axis show 120 percent? Is this another bug by Suunto? And then again, right after the activity, there is a rapid rise in the resources.

Is SV2 or R2 uses HRV to calculate resources?
-
@masi0 Yes. In the Suunto app, if you scroll below the graph, there’s a full explanation of what you’re seeing and how resources are measured.
-
@PetrMisek If you swipe across the graph, the app shows you the legend for each bar. Red indicates very high stress.
-
@Manuel-Extreme In the night yes, but not during the day.
-
@masi0 From in-app documentation, there’s no clear distinction between daytime and nighttime HRV measurement.
What is explicitly described is how “resources” are calculated:
Active state: recovery time from activities reflects recovery needs. Longer recovery times indicate faster depletion of resources.
Inactive state: HRV is used to assess autonomic balance. Higher HRV indicates more available resources, while lower HRV indicates reduced resources. Metrics like RMSSD, stress index, SDNN, together with heart rate, are used to evaluate stress levels.
So the focus is not on when HRV is measured, but on how it is used within the model. -
@Manuel-Extreme HRV is only measured during the sleep portion of the day. It’s not measured during the day, which wouldn’t make much sense anyway.
-
@maszop Are you saying that based on inference, or because you have the specifications?

“Suunto Race, Suunto Race S, Suunto Vertical, Suunto Ocean and Suunto 9 Peak Pro GPS watches can track your HRV during your sleep. Nighttime measurement is a reliable and easy way to gather comparable HRV data.”
-
Looks like this debate is going nowhere. @maszop in the picture above, you show HRV widget that shows average HRV during sleep specifically. But it does not disprove that 24 hour HRV measurement is part of the data stream used for continuous Resources calculation. So better arguments are needed. Or better yet, someone from Suunto who knows what they are talking about regarding this, to set the record straight.

Same goes for this claim. Provide more details, or is this just an assumption?
-
@Squirrel Measuring HRV alone is pointless because the data itself is useless. What’s needed is a trend based on repeated measurements under repeated conditions. That is, at night.

Agreed, HRV in isolation. But nobody said it is used in isolation to calculate resources.
What’s needed is a trend based on repeated measurements under repeated conditions. That is, at night.
You already got that in the HRV widget you posted above and also in the app, where you can look at long term trends and history. So what are you trying to suggest here regarding resources?
-
@maszop correct, but my assumption would be that Suunto as everybody else have added HRV during the day also since they added Stress measurment in Resources. Do not have any proof of that, but I doubt they only use HR to calculate that.
-
@aiv4r Your assumption is based on what?
-
@maszop Why do you keep insisting on answering with certainty about things you don’t actually know?
Stress scores are typically measured using HRV and HR, including during the day under optimal conditions.
That’s certainly how Firstbeat algorithms work.Does Suunto do it? According to its in-app documentation, yes
The study confirms that other sport Watch Firstbeat based primarily uses HRV (with HR as a supporting signal) to derive the stress score.

@Manuel-Extreme
You can’t get precise data from the watch’s OHR throughout the day – data that would let you reliably determine HRV and spot trends.
Garmin churns out hundreds of ridiculous statistics; half of them might as well come from a random number generator.https://forum.suunto.com/topic/14697/armband-and-zonesense
During sleep, you move your hand very little, skin temperature remains relatively stable, and blood flow is more consistent, making this type of measurement relatively easy for optical heart rate (OHR) sensors.
And apart from the measurement problem during the day, there are also hundreds of factors that affect the body, that affect HRV, and have nothing to do with recovery.
-
@maszop You keep writing your own interpretations that have little to do with reality. But that’s fine, I won’t insist, because I understand that I could bring all the documents and data, and you would still remain faithful to your own ideas without giving value to the topic
-
@Manuel-Extreme Find one place where Suunto says it uses HRV during the day for Regeneration and Resources. For now, you’re creating some kind of alternative reality.
-
@maszop Screenshot comes! One Moment please
-
@maszop here you have the answer. Sure suunto uses HRV for Ressourcen Management in day conditions.
