My VO2 Max never changes on my S9B, no matter what where I’m at with my training it’s always been 53.9

@dmytro
I think so, as it’s only estimation.

that’s suspicious, too

Maybe we should move this to the VO2max topic…
Anyway the new firmware works great for me. I tried hiking with hills and some uphill running, and the value did not drop. It used to drop dramatically in the past (being that HR was much more elevated for the same pace going uphill), now it does not.

@isazi I noticed the same

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…

@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).

Mine has never changed, it’s permanently stuck on 53.9. Would be great if it worked as it’s a value I’d likely to find quite useful

freeheeler

@suzzlo
hence I am more efficient at lower speeds…

suzzlo

@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.

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?

Dimitrios Kanellopoulos

@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…
