As a bit of curiosity, I’m interested to find out what the variation in HRV and Resting HR are withing the TR population.
I’m interested to see just how variable HRV and RHR are and how closely they correlate with training volume. Training Stress Score may be a better metric than volume, but this isn’t going to be published research!
Garmin has me at an average resting HR of 51bpm over the last year (52bpm over the last month). It takes the average of the 20 lowest overnight readings I think. So it might be lower than Garmin reports.
I’m in the process of buying/selling a house and moving, and have had a few injuries recently, so I’ve been inconsistent with my training, but over the past few months it’s been 5-10 hrs/wk riding and running.
Other than the recent hours being inconsistent, the HRV and RHR have remained in the same range for a few years now regardless of training volume and intensity.
I have never noticed much correlation between HRV and training load/volume, at least as tracked and reported by my Apple watch for the last 3 or so years. I don’t notice my watch’s reported RHR changing much either, but I don’t quite understand where the Apple watch comes up with this figure. I do notice a correlation between fitness and overnight low heart rate, which I look at more than the watch’s reported resting rate.
M/40, 4.1 w/kg
Recent volume average is about 11 hrs/wk.
~50 HRV
Apple watch says RHR is 47, but my overnight low is around 39-41 most nights.
Training volume: ranges from 6 to 10 hours a week.
I also do a fair bit of socialising around drinks, which consistently bombs my HRV.
RHR: 42
HRV: Garmin watch nightly average is usually 60 ish. If I drink more than half a bottle of wine it gets in the 40-50 range. In parts of the year when I am peaking, I get to the 70-80 range.
I have compared that with dedicated apps and measurements with chest strap, the difference seems negligible.
Training Volume - ~5 hours over winter, 4-8 hours over summer
~75kg, 290FTP
Average overnight HRV from Garmin Instinct 2 - 46ms, but coming off a sickness followed by my last MTB race, it’s typically in the 50-55ms range when healthy
Male 61y
70kg, 280 FTP
Weekly Volume: 9-12+h/wk (MTB in summer, now indoors)
HRV 21 (Oura 12mo avg)
RHR 55 (Oura 12mo avg)
My HRV drops into the teens once fatigue builds up, but goes back up into high 20s or even low 30s when I get some rest. All this assuming I drink no alcohol or eat anything of significance past 6pm. We are in bed by 9:30PM and usually up around 6:30AM. If I deviate much from the sleep schedule, I see drop HRV. All of this was more forgiving and easier to recover from deviations when I was younger!
