I am trying to capture RR Intervals during an activity. What do I need to use the log HRV feature and what are some ways to analyze the RR data? I see I may need a chest strap but which ones definitely work?
I have logged it with both the HRM-RUN and the old softstrap.
If it is like the Fenix watches, you need to download a .fit file to the watch. This file contains the setting which will enable the HRV logging. I can't remember the name, but it can be googled.
If you want to look at your HRV data from an activity, you can upload the activity .fit file to runalyze.com.
On 935 you don't need the fit file. You enable it in the watch under Settings -> Physiological Metrics (i run my watch in another language so so my "translation" of the menu items might be wrong)
I have an account at sporttracks.mobi too, but as far as I can see, it only records one HRV value per workout? If I want to see how and when my HRV changes during a workout, I haven't found a way at Sporttracks.
AllanOlesen67 To delve into the beat-by-beat data you will likely need an analysis package like Kubios. I'm pretty certain that none of the sports trackers will provide that level of detail. Maybe Golden Cheetah?

Well, I wonder what you want to see. HRV data is not that easy to read without lots of (medical) knowledge. Take a loot at e.g. Kubios documentation and publications on HRV. Maybe have a look at "Performance condition" data field or the graph in your activity's summary. This information uses HRV with others to get kind of real-time stat. There is some explanation in GC behind the question mark symbol within graph segment.
I am interested in the mechanics behind the lactate threshold detection and performance condition detection. So I would like to see the data which went into the calculation.
