Calculating VO2 Max

Bhima

Is there a cheap/free way of estimating this without all the lab equipment involved?

Recently Greg Lemond wanted Alberto Contador to "prove he was clean" and was making all sorts of claims about his VO2 Max using some kind of calculation... What calculation was that, and how reliable is it?

There's a test out there which involves running for 12 minutes and putting your distance into an equation to come up with your VO2 Max figure - does this work for cyclists and is there a cycling equivilent?

If there was a way of measuring it, it would be a good way to track your fitness every so often, on par with power measurement I reckon...

This one. Yes VO2 max is VO2 max. Remember the gym scene in American Flyers.

Do a 5-minute uphill time trial as fast as you can maintain. That will be your VO2max power.

You don't have a power meter on your bike? then you can use a online calculator to estimate power:

Divide that number by your weight in kilograms, now you have your power-to-weight ratio (PTW). Use this formula to estimate VO2max:

VO2max = 12 * PTW + 3.3

Cheers.

Surely the "meters covered per 12 minutes of running" depends on how good you are at running...? People seem to swear by that method, even people who aren't runners...

I used this: http://analyticcycling.com/ForcesPower_Page.html to estimate power using average gradients and average speeds from some of the hills I always time myself up. I've used 3 hills as examples in the calculation and it's come out with 41, 58 and 61.

So perhaps I need to do the test properly and with a powermeter to make things more accurate.

The problem with these though is that you are "estimating" somewhere along the line. The only way to measure your VO2 Max is in a lab surely, anything else is going to be off

I recently contacted a local university about VO2max testing. Cost is £60+VAT if you do it on your own or £50+VAT for 3 or more at the same time. Not much really. Alternatively, find a univesity with a sports science/physiology department and see if you can volunteer for any studies that require endurance trained athletes and involve a VO2max test. I did just that a couple of years back (for a study looking at the effects of low and high GI diets on glycogen recovery which involved 90mins cycling at 70% VO2max).

I can't see the point in estimating VO2max - seems about as useful as estimating HRmax using empirical formulae.

No.

Not that it is all that relevant a number anyway.

Bhima

Right, cheers.

I do know some sports scienc students, so i'll give them a call! Didn't think of that...

For running the "Beep Test" is a measure of your V02 max. Can't remeber though if the level reached proved how good you were or if it tied to a specific value, think the latter though.

I did the Rockport 1 mile Walk test.

With a brisk walk I got 55.
With a gentle run on the beach including groyne jumping I got 60.
(with a heart rate monitor and nokia sports tracker)

That is rated as the highest category.
I really didn't think I was very fit. So this surprised me greatly.

Is there a better way to measure aerobic fitness without spending more than £200?
How would I measure it on a stationary bike?
Where's the closest place to me that can do it in a lab with measuring air intake (Poole, Dorset, UK) What to search for in Yellow Pages?

The sports science department of your nearest university (prob Southampton).

But as has been said, VO2 max is just a number and pretty meaningless. Threshold power is a more useful determinant of potential cycling ability.

cougie

The bleep test can give you the approximate number and from that it can predict your race times. Its pretty close on for me - but its just a bit of fun really.

Edwin

+1 for NapoleonD's reply - if you win, then you're fit enough. If you don't win, train harder

Seriously, if you really want to know without spending money on the test, then try to volunteer for an experiment at your nearest university with a sports science department. That's what I did, FWIW my value was 65 ml/kg/min but that was a few years ago so I'd be interested to see if it's improved. Then again, I'm starting to be convinced into getting a powermeter to get some numbers to work with....

galaxyboy

It's probably only any good if you keep using the same method to measure your VO2 each time. I get 2 different medicals each year one uses the chester step test and i usually score mid 40's the other uses an old exercise bike and i get around 70. :?

APIII

I would think any of these numbers, VO2Max, threshold, etc. are only useful if you have a way of accurately repeating the test on a frequent basis, thus being able to measure any gains. Otherwise they're just numbers.

Interested why you say 'gimmick' here Alex? Do you mean the beep test is a gimmick or that the numbers you get are the gimmick.

I'm also interested in what Cougie says in that his beep score predicts his running times, Isn''t the beep test a very similar model as you (RST) use to get MAP results, which you then also use to extrapolate to predict race performance?

I'm not trying to be argumentative here, just thinking of the validity of any ramp tests.

Unless you're talking about TTs, Bike races are a poor way of measuring fitness. You don't get any figures/numbers from it because a lot of it is to do with tactics and outsmarting opponents.

I'm starting to think that something like the beep test or the "run for x minutes" test may be a good way of measuring VO2 Max vaguely - it might not be accurate, but if I do the tests regularly, at least the results will be consistent and there would be a chance that I could see some kind of trend...

freehub

If you want to go to all this effort to calculate your VO2 Max just give up.

shockedsoshocked

Just out of interest, why did you get a powertap if you can't afford the relevant tests to set up thresholds etc?

Bhima

How do you mean? You don't need to do a VO2 Max test in order to use a powermeter...

(Don't have a powertap yet, btw)

:roll:

Are you intending to just strap the thing on and go riding? If you are you may as well save yourself a few pretty pennies and not bother.

A proper lab test would establish VO2max, Max HR and peak power. If you can afford a powertap you should be able to afford that.

Bhima

Well, I didn't say I couldn't afford it, I just wanted to know if there was a cheaper way. When the new term starts, i'm getting down to my mate's UNI to get a free test anyway.

You can use a power meter without knowing exact VO2 Max figures. It's not essential that you know it at all, I don't see your point there...?

it's possible I've misinterpreted what the beep test is. I thought this was one of those "wear your heart rate monitor and lie down for five minutes to find out your supposed VO2max" tests

"Beep Test" as I know it is shuttle runs over a 20m distance in time with a standardised "beeps" soundtrack - as the test progresses, the beeps get closer and closer together so you run to exhaustion. The test stops when you can't reach the turn before the next beep and that is your score for the test.

Used by many bodies who set minimum fitness entry requirement standards (Police service for instance).

Sweet Jesus.

My point is if you're getting a powertap and will be doing a proper lab test, your VO2max will be included in the results. Trying to find some "cheap" (read unreliable) way to establish yours is pretty pointless.

You might want to try doing some bike races before making that judgement...

Gotcha. I was thinking bike riding and HRMs with "features".

Yeah - that would be akin to a MAP test. In general, MAP is a little higher than you might call power at VO2 Max, although that in iteself is a pretty fuzzy notion since there is quite a wide range of power at which one can induce VO2 Max.
