Maintaining a high VO2 max in one's 40s and 50s is important for potentially extending lifespan by a decade due to inevitable decline.

“and then you can reduce the um rate of decline by about half up to certainly up to your 70s probably”

“but even if they drop off 10% per decade they start at a much higher Baseline so if if your Baseline is 60 versus 35 and you lose 10% per decade you're still going to be way way way ahead way ahead and and at age 60 or 70 you're going to have a V2 max value higher higher than um uh you know 30-y old”

“the reason we push so hard Mike for our patients to have as high a V2 Max possible as as as possible when they're in their 40s or 50s is based on this inevitability of Decline and with the hopes that we're extending Life by a decade”

“this number is going down at about 8 to 10% per decade depending on your your training volume”

“And what we then overlay on this graph is, hey, if you want more juice here, let's get your V2 max from 40 up to 50, which will take us a year, maybe 18 months, but it's 100% achievable. And now look at how that changes the arc of your life. Look at what that does to extend your ability to do things over time.”

“VO2 max (among other performance traits) can be improved into one's 50s, 60s, and beyond.”
