Watch App : HRV

HRV app. Discussion, report bugs, suggested features, etc...

HRV
Get the app.

Graphing.
The design currently only saves to 1 location per day. The timestamp is taken when the test starts, so autostart will take the timestamp at the scheduled time. This means that any saved test will overwrite any previous test of that same day. A day is calculated from the local timezone, so travelling won't disrupt the storage so long as you have updated the timezone before starting the test. The averages are a 30 day mean average.

Description & Explanation
Wouldn't that be nice. Will happen, but might take a while.
This page could be useful.

Notes
- Your device must have firmware that supports Connect IQ Apps.
- You can save the results by creating a log file. To do this you must work out which name has been applied to the HRV app file. The apps are in the /GARMIN/APPS folder. It will be a name something like A6227C9B.PRG. You then create a log file with the same name, e.g /GARMIN/APPS/LOGS/A6227C9B.TXT. Each reading you save will output a result formatted as ISO8601 date & time, hrv, avg pulse, 30 day hrv avg, 30 day pulse avg.

In a move to revive this app somewhat, I have released the source. https://github.com/sharkbait-au/HRV_iq

It would have been great if the app showed results for HF/LF, so that there will be
a reference to fatigue or readiness of the Sympathetic or Parasympathetic systems.

I love the app, use it every morning.

Is it only me or did FW 6.80 break the app? I only get the crash-screen when I try to start it...

FR 235 compatible...

Hi,
I've been keeping track on any updates for this app. I would really love to have the app on my FR 235. I see it is now available for the fenix 3 HR. They both have the same sensor, is there any chance we might be able to use this app on the FR 235 soon?
Thank you!

Thanks for the app! I don't bother with the garmin stress score.

I would also love to either see the output of raw data. Let us know what we can do to motivate you.

I love the app, use it every morning.

Also very keen for the HF/LF feature, and maybe the ability to export the results to MapMyFitness/GoldenCheetah? At the moment I'm entering the data manually.

Thanks for a great App! Appreciate it.

Agreed! I would love to see this for the Forerunner 235 :D

Doesn't look like it would provide very useful information according to this analysis of the "r-r" data : http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=149812

Any hope in supporting the new Forerunner *3* models? Meaning 230, 235, 630?

Thanks for the great app!!!!

LF/HF Measurements

It would have been great if the app showed results for HF/LF, so that there will be
a reference to fatigue or readiness of the Sympathetic or Parasympathetic systems.

I love the app, use it every morning.

I am a physician who specializes in measuring HRV and other autonomic measures routinely in my clinical practice. HRV is most greatly reflected in the parasympathetic branch of the autonomic nervous system and is what clinicians refer to when stating HF (high frequency).

LF (low frequency) represents the sympathetic branch.

Parasympathetics can be measured a variety of ways but rMSSD combined with paced breathing seems to be the most consistent method in portable devices. The sympathetics are more difficult to measure reliably.

Hope that helps.
