What is VO2 Max?
Scientifically, this is the amount of oxygen the body can use in millilitres, per kilo that you weigh, per minute.
Clearly this definition of VO2, whilst correct, doesn't tell us much because how do we know what to do with the information?
So, more simply, testing an athletes VO2 maximum is a measure of the
endurance capability of an athlete. Basically,
those who can uptake oxygen more efficiently can work harder than those
who can't. Training will, over time, increase this level, although genetics also have a role to play here, so to and extent
you "get what you are given!".
There are various ways in which this can be measured. The actual figure that
is produced from some of these tests is not as important as the athletes
measure of what was achieved and the aim of improving this over time.
The most scientific way to do this is to get a laboratory test done on a
treadmill with an oxygen mask and being linked up to a computer.
However, this is beyond the means of most athletes and isn't entirely necessary.
It is important to note that whilst the lactate threshold limit an athlete has is loosely related to their VO2 Max, there
is enough variation here that a runner with a very good VO2 Max, may have a significantly lower lactate threshold than another whose
VO2 maximum isn't that high.
