# VO2 max

I have never paid too much attention to the technical
aspects of training so forgive my ignorance on vo2. I had a
stress test last summer and just realized that the results
that I got included my vo2 measurement. I wonder if there is
a calculator that would predict what race times I should be
able to achieve based on vo2. Also, at the time, I had just
started training for a half marathon so my distance was
increasing. Will vo2 change much with training?

You can try this calculator, which calculates based on a
race time, but also gives a VO2max estimate and predicted
times for a large number of distances. So you can adjust
race times until you get the desired VO2max, then look up
all the equivalent race times. The purdy column is the most
accurate for distance events.

I also have a calculator for Jack Daniels' Oxygen Power
equations that can calculate any distance from any other
distance and also gives VO2max estimates. As this is an
Excel spreadsheet, I can't post this, but send me an email
if you want it.

Hi Lyndon:

I only wish VO2 max predictions were true...I measured 76.4
vo2 max at USC back in 81, which predicts a 28:40 10k and a
2:13 marathon.

I also held the record for a while as the person able to
stay longest on the vo2max treadmill (20 minutes with the 3
minute protocol with increasing grade & speed)

Unfortunately, my bests were only 33:35 10k and 2:37
marathon, although I retired from serious racing after only
3 years -- maybe I could have gotten faster if I'd been
more patient.

I was trounced by a friend who got only 62, but could run
32:30. He had a *very* smooth stride. I bounce quite a bit.
Apparently, I have a good motor, but "square wheels".

By the bye, since you are regional or national class in your
specialty, and a coach to boot, do elite competitors in the
100/200/400/800 world have high vo2 maxes?

Lyndon, Thanks for the link. I think this tells me all I
need to know. My vo2 max

for the general population but clearly not very good
compared to other runners. It seems my best half marathon
would only be 1:52:05!!

Any chance I can improve on that? Jane

First, unless they had you breathing into a mask or a tube,
the numbers they gave you from the GXT were estimates only.
The formula can be a bit off if you are active (the original
population for many of these estimates were not fit people).

Second, if they did use a metabolic cart, many are notorious
for being poorly calibrated. The technicians often do not
calibrate them properly or after every test as should be
done. I am skeptical of most VO2max readings unless I
personally know about the place doing them!

VO2max can be improved with training, but for a fit person
it will not rise by much. The most a fit active person can
expect to raise VO2max is 20% and that would be at the high
end. Data (unpublished) out of the Australian Institute of
Sport saw a 7% change in Vo2max amongst its pro cyclists
from start of the training year to Worlds.

VO2max is but one aspect of being a better athlete. In
running your pace at VO2max (vVO2max) is a better predictor
of performance. Pace at Lactate Threshold is probably an
even better predictor (I say probably only because I am not
aware of any studies that have compared the two). Running
economy is another factor. That is how much oxygen one uses
to run at a submaximal pace.

There are charts, but I would call them useless. In
your case (I am assuming) you did not get a real
VO2max measurement to begin with so you would be
putting in garbage.

As I will note many times, I distrust most if not all VO2max
measurements.

800m runners will have a very high VO2max. The sprinters
less so. Part of the determination of VO2max is muscle fiber
type and the sprinters tend to have more fast twitch.
