There is a nearly linear relationship between power output and oxygen consumption (V̇O2), where a 10% increase in power typically results in a 10% increase in V̇O2.

“power is a very good extremely good uh there's a very good correlation between power and V2 obviously more work more oxygen consumption simp simp simple as that and this is also a this is a curve you can almost say it's a lineary relation relationship so if you increase your power by 10% you will normally increase your oxygen consumption by 10 % as well”
