# Calculating the power that elicits a % of VO2max, based on results from a VO2max test.

Hey

For my dissertation I am performing a VO2max test on an SRM ergometer. I then need to work out what power would elicit 70% of their VO2max.

Is there an equation that calculates this?

For example (numbers pulled out of the air here)

A VO2max of 60 ml/kg/min is achieved, and the power at which exhaustion occurred is 500W.

Does this mean to cycle at a steady state of 70% VO2max, they would cycle at 70% of the power at exhaustion, i.e 350W

I would really appreciate some help here. I have searched for hours for an answer and have come up short.
