Vertical 2 resources
-
I went cross-country skiing for 2 hours. Average HR for 2 hours was 149bpm (H10 strap). Resources went down pretty quickly (finally
) but i don´t understand red stripe - under load, this was 45 minutes after activity and it is bigger than blue one before it, so resources are going up when I am under load?? Strange -
@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.

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.
