Training status (VO2 max) unchanged for a weeks/months - Forerunner 955 Solar

Since I started to use new Garmin Forerunner 955 (July 2022) my training status (and also VO2 max stats) is stuck on "Maintaining" - no matter how hard I train, rest etc. (see attached screenshot below). Two changes occurred (from maintaining to strained and back to maintaining) when my FR955 was updated. My trainings are variable and when I used FR 745, the training status and VO2 max statistics reflected my training load pretty well.

I'm on sw/fw version 12.25B, I see the same stats on FR 955 and in Garmin connect.

Do you have an idea when this bug will be fixed?

Thank you!

All,

We have other reports of this and will be updating the main thread on this report as more information becomes available:

VO2Max isn't increasing

What happens when you look in the 12W or 4W View..there seems to be more variability in those views

I know, but the situation is the same there. Maintaining, maintaining all the time. Only in the weeks around the FW update date there were changes.

Same here, maintaining. The runalyze shows that my vo2max is increasing

Getting back in a productive state, VO2max trending upwards

I've been the same since 4th August.

I read a post somewhere about changing your profile, which I did, and that changed the status for one run! I tried changing it again with no effect!

I will update my findings after the reset I've done 2 weeks ago at the request of Garmin - Kevin.

Change of max HR will most likely cause vo2max to change.

Another user has shown data that vo2max is less sensitive now compared to the past. ie vo2max rises and falls at a lower rate

What is your actual vo2max from lab or estimated by a 1.5 mile run test ?

Personally I don't expect the Garmin VO2max to accurately represent a lab test result but rather as a relative performance/fitness incremental changes.

Absolute (lab tested) VO2max can easily be drastically improved by decreasing body weight through fasting for example, I routinely drop around 8-10% in 5-6 days fast. A lab test of 50 before would be ~54 with actual fitness unchanged. Garmin VO2max don't take body weight into account if I understood it correctly.

At least with the current non-functional VO2max we won't be stuck in the completely useless "Unproductive" status, I prefer to be stuck in "Maintaining" forever.

Hi DPSK

I might have changed my max HR by 1 point when I adjusted my profile, which would back up your suggestion for one run.

I have no idea what my actual VO2 max is but I'd estimate 55-60 based on the calculations i've seen. My watch says 68!

Not sure how you get the estimation.

Another alternative to estimate v02max without going to the lab is the 1.5 mile all out run test.

Maybe you can compare Garmn estimate with that test.

If you think Garmin estimate is too high, you probably set your max HR too high.
