@Eugene-Benkovskiy said in Heart rate variability:
For me, it was a little bit strange not to find a described feature on the site in the Suunto app (it’s really missing). So, after some time of searching, I decided to ask the community about it.
Sorry if I sounded somewhat crumpy, wasn’t my intention. R-R in the watch spec isn’t wrong, Suunto watches indeed record R-R intervals and also pass those along.
And in a way Movescount and Suunto App are providing the same lavel of R-R support, meaning that there’s no (valid) metric or chart, but both Movescount and Suunto App actually provide access to this data through activity export and sync, so you can still go through some HRV analysis with 3rd party tools (like Kubios) and services (like Runalyze).
That said, R-R samples collected during physical activity are not considered to be very useful, there are just too many variables. For analysing trends and current condition, measurements are usually taken at the same time of the day, when rested and without any external stressors.
