VO_{2}max is a synonym for the maximum possible intake of oxygen. It is the amount of oxygen which is processed by the body under maximum activity.
It essentially depends on four factors.
First, the oxygen needs to get into the lungs. Therefore it is an advantage being able to breathe in and out a lot of air within a given timespan. Blood needs to
absorb the oxygen and transport it to the muscles. The heart pumps the blood through the blood vessels. Finally, the muscles need to absorb the oxygen transported
by the blood and need to use it. Parts of the VO_{2}max value is genetically determined but the other part is definitely
trainable. VO_{2}max is a good indicator for endurance capacity of an athlete but many
other factors come up when aiming for a win. As a consequence athletes with a lower VO_{2}max can beat athletes with a higher one.

The calculator applies the following formula:

\( VO_{2}max = \frac{6\: min\: Power \cdot 10.8}{weight} + 7 \)

Using this formula the VO_{2}max can be determined very vell. To get the exact VO_{2}max value a
fitness test in a lab has to be done.

My calculated VO_{2}max corresponds very well to the value measured in a lab. With my 66.5 kg and a power of ~400 W for 6 min the VO_{2}max
is calculated to 72.0 ml / (kg ⋅ min). It differs only 3.0 ml / (kg ⋅ min) or 4 % from the measured VO_{2}max of 69.0 ml / (kg ⋅ min)
in the lab (17 November 2017).

To calculate your VO_{2}max you need to know your body weight and the power you can sustain for 6 min on a bike. A powermeter can easily measure this
6 min power. To do this you should choose an ascent and give everything for 6 min. At the end you should be completely exhausted. Don't go too hard at the
beginning, because you should aim for a reasonably steady power output. The average power output for these 6 min will serve as a basis for the calculation.

If you don't have a powermeter on your bike you can do the test on a hometrainer too. Therefore you should approximately know how much watt you can produce for a period of 6 min. Now you start riding with this wattage. If you feel that the choosen wattage was too low, you can increase the wattage for example one minute before the end. Finally you have to calculate the arithmetic average (attention: if you did 5 min at 300 W and 1 min at 350 W the average is calculated to (5 min ⋅ 300 W + 1 min ⋅ 350 W) / 6 min = 308 W).

This data applies to men and is indicated in ml / (kg ⋅ min).

Top cyclists have a VO_{2}max of above 80 ml / (kg ⋅ min). The four times Tour de France winner,
Christopher Froome, has a VO_{2}max of
84.6 ml / (kg ⋅ min), for example. Miguel Indurain once had a figure of
88.0 ml / (kg ⋅ min) and Greg LeMond even
had 92.5 ml / (kg ⋅ min). Anton Palzer, who
switched from Ski mountaineering to Bora - hansgrohe directly into the highest ranks of cycling,
has a VO_{2}max of 92 ml / (kg ⋅ min).

Cross-country skiers tendentially have higher figures because more groups of muscles have to be supplied with oxygen.
