High VO2 max indicates a long-term commitment to exercise, not a recent change in fitness.

“so if a person has a high VO2 max they have been doing a lot of exercising for a long time that doesn't have to mean their whole life but they didn't just decide you know a week ago oh you know I'm kind of unfit but I'm going to start exercising and I'm going to get fit no no no no if if your if your VO2 max is in the top two or 3% of your age group you've been at this for a while and therefore the V2 Max measurement is really an integration of work that you have done it's that work that is being captured through the integral of the final metric or the test”
