Power vs vo2max

Depending on how approximate you're looking for, FTP is approximately 75% of pVO2max.

I'm pretty sure I recently read somewhere that there is a approximate relationship (formula) between FT wattage and your Vo2max. Now I can't seem to find it. Does anyone know what the formula is, if it in fact exists and is not a figment of my imagination? Thanks, Bone

Read entry number 2.

possibly not quite, depending on what protocol was used.

however, for the vast majority of cyclists FT will be in the range of 72 - 77% of MAP, see, http://www.cyclingnews.com/fitness/?id=powerstern

And for the relationship between wattage and VO2max; I assume that you could use the basic chemistry formulas how carbonhydrates are oxidized, and how much energy is released in the process. Furthermoere, there is the commonly used apprximation of ~25% efficiency, so that 25% of that energy can be converted to power. Yes, I remember I've seen that calculation somewhere, but can't remember the result. Too many years from high school were this kind calculations were done 4 * 2'... anyone here to try?

[font=Verdana]"the oxygen consumption can be converted directly to kcal/min by multiplying by 4.8 kcal/l O2"[/font]

[font=Verdana]Furthermore, assuming that 1 kcal energy consumed means the same as 1 kJ energy produced for the bike power meter, it's easy to calculate the relationship between VO2max and power at VO2max.[/font]
