Garmin edge 1000 VO2 max calculator

[E65Ross]

How does this work? Mine seems perhaps a little optimistic..... Apparently you work out VO2 max by getting your 20min test power, multiplying by 10.8, dividing by weight in kgs, then adding 7. For me, this is (241x10.8)/54 + 7 which gives just over 55. Yet my garmin which is set to automatically calculate it shows my VO2 max at 65.

Im not fussed, it is what it is, just curious more than anything else!

Cheers

I've not looked at the number my Edge 1000 has chucked out yet, but my 920XT took quite a few runs to build up a picture. Even then one longer run could throw the number higher. However the average position is very close to my actual VO2 Max test.

That equation would give Chris Froome a 20 minute power of 532w.

His 20 minute is more like 400/425....................

That equation looks crap.

Interesting.

I'd have thought my garmin would have been pretty accurate. Today it's showing 64 which isn't too shabby.

The only way to measure V02 is by having a gas analysis test. Anything else is completely pointless.

I'm not sure why you would want to know it either, it is a pretty meaningless value in the grand scheme of things.

As per my first post.... Just out of curiosity

It gives choppers something to bore the tits off others at the cafe with...

Really? A cycling computer that doesn't measure your O2 intake, CO2 exhaustion, take into account body type (What about if you have one arm?) is accurate?

Nah, even the FTP calculation is rough.
