VO2max levels confusing

Efejota

My case is totally the opposite. 51, not a great athlete, running as much as 10 kms around 5:45 and the VOMax in amazingly high levels. Compared to those in Runalyze for the same run, I think that the ones from S9B are very very optimistic.

@Efejota I run at the same pace and get 51. Looks ok.

Runalazyze is not using the firstbeat method.

Also you wanna make sure you have setup your max hr correct and zones correct.

@Dimitrios-Kanellopoulos I think @Efejota meant age 51, not VO2 max = 51

Anyway only lab test using gas analysis system can say how accurate is Firstbeat or any other algorithm

@Dimitrios-Kanellopoulos I am not sure what Fitbit measures but I found it highly overestimating my aerobic fitness and my daily calorie burn. Sometimes it told me I burned 4000 to 4500 calories just by walking with the dog twice on a Saturday… It’s sleep tracking is very good though

My vo2max highly depends on gps signal.

Best gps situation -> 64 vo2max
So-so gps I->. 62
Bad ->61

what I’ve observed.

Normally, my vo2max on S9B is higher than Runalyze,
But since a couple of days, Runalyze is higher than S9B.

@Efejota My S9B provides VO2 max below my lab tests, but virtually all my running is on trails so this is understandable. Your HR settings will affect VO2 max too.

Well, I guess that we could debate about it till end of the days. Runalyze vs Firstbeat (Suunto) and we’ll never come to any conclusion. RA and FB calculation will never meet, just because both are using different algorithm and none of them is able to handle intervals and trails run in correct way. Not even GAP.
As was mentioned here here already (and many times before) real value can be measured in lab only.
Well, so you can go, let measure your real VO2max value in lab, and the set a correction factor in RA. Of course, do not forget to remove all interval or trail runs from calculation (in RA). Keep calculation for races (single race runs, not multisport races) and steady runs. Then one should be able to keep track on nearly real VO2 max. That is for Runalyze (RA).
For Suunto calculation, it is just not possible (afaik) to exclude specific run from calculation…

Oh yes, and please keep in mind that effective VO2max in RunAnalyze is calculated from VO2max and running efficiency. So, here is another factor in game telling us that you just cannot simply compare values from Runalyze and from Suunto. They are just not the same…

Have a nice day all!

but we are discussing the algorithms right？
