New software update for S9P-S9B-S9-S5P-S5 and S3 devices 2.20.28

Yesterday I did a run (no trail running), 9 km flat out, not much more in me, I wanted to run 10 km but my running partner got injured at km 9. My pace was 4:04 min/km, and avg HR 163 bpm (47% Z5, 40% Z4 and 11% Z3) and my VO2max went from 54.3 to 55.2, so 0.9 up.
This was more or less what I expected, and I’m pretty sure that If I run some km mainly in my Z4 it will go up again. But then I have my doubts with trail running, will test more.

@cosme-costa keep in mind that the Algo afaik tries to find a best effort with good hr readings and flat ground. That’s it’s preference I think. I think as the FB Algo is a black box.
-
Could it be that you can do VO2max only once per day?
Today I started trail running.
At start after a few meters I forgot something.
Then I quickly stopped, canceled and not saved the activity.
There was a V02max on summary in watch.
Then I started the second time for real.
At the end no VO2max. -
@freeheeler Polars „lay down“ VO2max test yields strange results for me (between 30 and 42). But their running index is quite similar (40) to what I get from Suunto 9P (40.5) or Garmin (41)

@chrisa
VO2max is a blackbox for me… I recently had better values when going slower than when I did faster sessions…living sideways
-
@freeheeler it’s not about pace, it’s about how HR is affected by intensity…
I mean, Firstbeat VO2Max algo, uses speed vs HR: “The Firstbeat algorithm analyzes the relationship between HR and exercise speed at multiple points during a training session” link so if the algo, “thinks” that at low speed you are proportionally consuming less oxygen that at high speed, it will give you a better figure…

@freeheeler For me VO2max is very reliable and plausible on Suuntos. The ratio HR and pace is crucial, not only fast running. For example I did a lot improvement to my running technique. I do not run always faster, but with a way lower HR (same speed). My VO2max improved much. But I think VO2max should in general give a feeling of max power. But algo can also be interpreted, how efficient running is. That’s how I use it. Of course there are better days in my running form and normal days. Maybe there is also a litte smoothening over last trainings (but this I do not know).

@chrisa

@suzzlo
hence I am more efficient at lower speeds… -
@freeheeler I think you (and me, and everyone) should be efficient at the speed you are used to train.
Also, I think this algo is designed to give value to us (amateur athletes) and not to be a lab test substitute…
I mean, it works in also in not high demanding sports like walking.BR

keep in mind vo2max can drop and rise for many conditions especially a health related issue such as inflamation
-
@dimitrios-kanellopoulos What is the criteria, when there is no VO2max calculation at the end of running / trailrunning?
-
@mountainchris I dont know
-
@dimitrios-kanellopoulos maybe also first running calibration (I have a new watch)

It took a good long time for my values to stabilize after starting a new watch. At least a month.

There should be an option to deactivate VO2max for hiking. It messes up running VO2max a lot. VO2max is getting useless because you do not see your VO2max running anymore.
I wonder if ascent is really calculated fully in. Normally my VO2max is 53 - 55 and with fast hiking with much ascent only 43-35… Can’t believe…
-
@mountainchris it should be on / off. The same way hr for workouts is implemented.
-
@mountainchris or just split into walking/running vO2max.
-
@dmytro Since a few days I used hiking profile. This messed it up. Before I used mountaineering. There was never a VO2max calculated. So in running I had my pure running VO2max. That was accurate. I hope that mountaineering is still after update without VO2max.
Even if it would be walking, I can’t believe the difference and wonder if all ascent is calculated in. But I hope my solution before to use mountaineering still works
-
@mountainchris I think it does
