I think that’s the standard methodology but there’s merit to using anything from laying down, seated or standing. Ultimately you are trying to measure your minimum heart rate in a rested state which can be any of those and as long as you are consistent you can compare to anything. If your RHR is high such as when ill it will be elevated in all positions above the baseline.
I can’t remember whether it was just for people with low RHR or all fit people but when taking HRV (measuring the time between beats) it is sometimes recommended to do them standing as too low a HR results in lower quality data due to not enough activity during the measurement interval.
It’s the only time I’m really laying down, but I also see no real different values between sleep and other resting much, but I have no idea what the definitions are really!
Ran with my bubble buddy and was dreading it, I rarely run on consecutive days and had a poor night’s sleep.
10 kms 54:18… over two mins quicker on similar roads more importantly av hr of 135, continued on for another 5 k or so at about 5:30 kms holding mid 130”s hr.
For some reason in my head I had the PB down at 6:41mile pace.
So by mile 4 I was thinking this might be a good un. Then 5 & 6 were slower so was like, bummer.
Get home and look at the splits.
The last .22 miles was 7 seconds slower than last time.
