@kosmoplan I don't see the problem about dropping a major update before leaving for 3 weeks holiday and 6 months papa-perm.
My colleagues might, but... they'll have forgotten but the time I get back.
@kosmoplan the best time to be at work. No emails, no meetings, quiet office.
Then take your 3 weeks mid august when everyone comes back and tries to be productive.
@john Oof, BLE is a huge pain. I still have to work through a couple other things before I get there, but by that point I think I'll have a way to save a stream of data to the file system for later viewing.
@dcz if you’re looking to apply this to your bike computer. I’d like to have raw data from the sensors in the saved data, but happy to see massaged data on device.
Dunno how close you are to implementing BLE or ANT though ;-)
@dcz yeah. So for me, 201 is peak rate - reproducible number consistently in similar scenarios with good sensors.
I’ve seen over 220 once doing a maximal test untrained when I was a bit younger. Then I could hit 211 on demand when fit. The equipment wasn’t what it is today so I consider that an erroneous reading.
@dcz HRV is just that variation of the timing between beats. I think you probably want to look for a whitepaper called FirstBeat, they link to the original research. I’d look it up but pinned to a chair by sleeping baby atm.
@dcz I’d also say that a single outlier is a useful data point. From my own observations going from untrained -> trained I see a drop in peak HRs as efficiencies kick in from training
@dcz so ok you don’t take the time between 2 beats and directly extrapolate BPM. Neither should we enforce that BPM is 60s worth of data (not that you said this).
Proper analysis comes into play, as well. Let’s say I get a max HR of 201, it’s an anomaly unless it’s reproducible.
@dcz again I’m not sure that’s the case as Heart Rate Variation(HRV) tends to stabilise during exercise. https://www.researchgate.net/publication/339800303_Speed_and_Heart_Rate_Variation_During_Marathon_Running_in_a_Hot_Environment
Again depends on the quality of the equipment being used. But HRV as a proxy for stress(es) is a fascinating subject.
@dcz I don’t know that’s the case anymore if you have a belt / monitor capable of HRV. I’d say it’s more likely to be software attempting to remove bad readings.
