Or another way would be to be able to define a timestamp e.g 8:00am and take the data which is available for this time stamp. so it would assure similarity in getting the data.
Average over the day depends on so much factors including the training you did on this day etc.
Edit Addon:
There is a nice little IQ App called Test HRV - which writes a fit file after doing a 3min HRV test. The .fit file includes also the RMSSD fields - what would be nice if there would be a way to use this .fit file and insert the value into the wellness data.
I’m sceptical about that IQ addon. It uses wrist heartrate-data and can’t connect to a strap. HR data from optical sensors is a challenge and most manufacturers heavily filter the signal to extract the heartbeats. I wouldn’t trust the HRV data from such a source. One missed beat can make a huge difference! But technology keeps evolving so I’m not going to judge without having the results from a good comparison.
Fully agree and I will test it in comparison with EliteHRV, to validate accuracy in next days.
However, since Garmin is calculating a lot of figures based on Firstbeat technology, I assume they measure HRV anyhow “internally”, but obviously do not offer any User accessible information.
Not sure what the Garmin Developer API delivers, but as @David mentioned above it seems to be a little complicated.
apologies if this has already been covered. I’m thinking of the Garmins “Body Battery” reading. It might be useful to put into the readiness field whatever your body battery reading was at the beginning of your workout. This could then lend itself to show trends over time of how you might have gone against your ‘readiness’
Is it possible to have the same order for the health fields? Humor and Hidration starts from the “top/best” instead of the worse like the others, see screenshot.
What about the HRV rMSSD and SDNN fields? (FWIW, I have “log HRV” set on my garmin watch and bike computer. Is there a way to see that data for an activity when I use a polar h10?)
Check the available fields which can be shown on an activity - go to Activity > Fields at the bottom. I just had a quick look and I don’t think Garmin HRV log data points are available
I also use EliteHRV with Polar H10 strap. I haven’t started adding it to intervals.icu though and would like to somehow try to get the Resting HR, HRV, and Readiness Score into intervals.icu
I found that you can export all the data very easily from the EliteHRV app, which sends you a link and downloads a zip file. The file has a bunch of txt documents for each day with RR intervals as per attached. @david is there any way intervals.icu could import in this zip file and use the data to update wellness HRV data for the days in the zip file? See screenshot of file format within the zip and some sample data.
That´s only RAW not-analyzed RR data. Intervals has no way of analyzing that RAW data (yet).
Getting avg RHR from this is rather easy but calculation of RMSSD needs filtering and checking for artefacts. That requires some quite advanced algorithms.
What you need is the result from that series of heartbeat data.
Thanks, EliteHRV is able to sync to Apple Health. There is an option to export all Apple health data. Opening up one I can see this data from EliteHRV.
This value 46.96 looks to be SDNN from EliteHRV.
Ideally like you say I would be able to just export the Morning Readiness information as per screenshot but doesn’t seem to be possible. I might just have to keep this separate to intervals.icu
I find having the data in intervals to be very beneficial to provide context to my other data, feelings and general training.
Yes it is frustrating having to manually input but it takes about 20 secs to input the 2 data fields i want (HRV and Readiness) and the benefits outweigh the inconvenience of manual input.
Very useful info thanks guys, I might look into HRV4TRAINING also but do agree it takes very little time to update manually but always like to have it automatic if possible.
I also noticed that intervals.icu shows my resting heart rate automatically from Garmin however this is always lower to when I do the HRV test in the morning. So maybe in intervals.icu I use the empty Avg Sleeping Heart Rate field to record this value. The garmin value I really consider to be my sleeping heart rate, reading on Garmin it is the lowest 30min avg heart rate for the day.
Starting putting in some data manually from EliteHRV results, and it is looking good, you can see after a hard effort where the red dot is, the following day the HRV resting HR goes up, and the HRV goes down…Then I have the Readiness Score and average 7D. That is a good start. I don’t think I will convert to HRV4TRAINING for now as I have been using EliteHRV for quite a while so might as well stick with it
I am using the Average Sleeping HR field and Labelled HVR-RHR in the graph .
