HRV
-
@szaboat74 HRV is age-dependent as well and decreases with age. Mine is similar to yours.
-
@szaboat74 Overnight HRV measurements for me are not optimal for many reasons, so I don’t trust these values at all (whatever the brand, of course).
-
@cjanevate Just to be curious, have you achieved medical tests that leads you to that statment ?
I have not, so I don’t know if values are “precise”. I pay more attention to variations and long term evolution of values.(The only value that I’ve “medicaly” mesured was my VO2Max. 59,5 mesured while my SV tells me I’m around 56 - but I do almost only trail running so SV estimation is under evaluated. I find it not so bad however).
-
@Tieutieu without elaborating, I mean that I much prefer morning readings over night ones, which are much more consistent with my stress/workout/etc. response.
-
@cjanevate ok understood !

A parallel comparison with Garmin and Polar shows that the measurement of Suunto is wrong. The sensors of Suunto seems to be outdated.
-
@szaboat74 the measurements of Suunto are wrong. I checked in parallel the measurements via Garmin and Polar. The results are round about 10 ms higher as Suunto is showing. It seems to be that they in general have a issue with there sensors. HR at the wrist is also faulty especially during exercises. It is very sobering in itself when this is the case with a current model like the Race.

@mr-quality wrist HR measurement accuracy depends a lot on how you wear the watch, and there may be individual factors as well, like dark skin or lot of hair. For me, when using a 3rd party velcro watch strap, tightened enough, wrist HR is pretty accurate on both the Race and S9B.
-
I have the same, used a garmin and a coros with a baseline of 35-45 ms accros both brands, with suunto I m in the 25-35 ms range, not a big deal I think as hrv is something you should consider compared to a baseline values and see its evolution to reflect you day recovery
-
@mr-quality it seems there are not using the same hrv définition -there are a few. So you cannot directly compare the figures.
-
@raceaddict I find the HR pretty accurate on my Vertical.
Yesterday 160k on the bike. Wahoo bike computer via Polar HR strap Suunto on wristAverage HR was identical. Max was 3 beats higher with strap.
Some of the zones are different, but I’m not sure if that is more down to set up
Anyway it is awful for some people but pretty accurate for others. Which seems to be the nature of wrist HR.
-
@raceaddict The calculation is medically fixed and predefined. It is identical in the descriptions. In this respect, the values determined are decisive and these in turn come from the sensor. It is worth taking a look at the number of sensors and positioning at Polar and Suunto. Based on this, I would assume that Polar has a higher accuracy.
-
@Audaxjoe Maybe. The test reports criticized what I also noticed. During sporting activities with rapidly changing pulse rates, the sensor on the wrist does not keep up and shows excessive deviations.

Even wikipedia doesn’t agree https://en.wikipedia.org/wiki/Heart_rate_variability
See Analysis paragraph. I don’t want to count all of them, too many for sure.You cannot compare absolute values vs Garmin/Polar, but the trend should be the same.
-
If you know something about this topic, you should know that there are different methods for the hrv… Suunto uses RMSSD I think. I‘m nearly sure that the other brands use others metrics… that‘s why you cannot compare the absolute values.
If you are interested in this topic…

Comparing an AppleWatch with Suunto I get very similar readings, the trend is always the same even if the numbers are slightly different.
-
@SuperFlo75 The descriptions of the methods are identical in the freely accessible operating instructions. The difference with Polar is that they only record the first four hours as soon as you fall asleep. The data is recorded for the entire bedtime and can be viewed and analyzed. This means that I would sometimes have even greater deviations, as the HRV is often higher on average after the four hours.
-
@raceaddict The method used is the same for all of them: RMSSD. In this respect, Wikipedia also confirms that this method is medically fixed. If everyone uses the same method, a comparison must be possible.
-
@mr-quality but what time suunto neasures the HRV? the first 4 hours from the sleep or the whole time from sleeping? No infos in the manual?!
-
@GiPFELKiND According to the information directly in the app, the entire bedtime.
