was more predictive than traditional risk factors like coronary artery disease, smoking, and diabetes, right?

So I'll put numbers behind this because it gets even more interesting.

The cardiorespiratory fitness is inversely associated with long-term mortality and not observed to be an upper limit.

What that also means is

there doesn't seem to be any reduction in the benefit by continuing to increase your VO2 max.

So in other words, the higher your VO2 max goes, the more it seems to preserve all-cause mortality risk.

So there doesn't appear to be in this study.

In fact, you'd see the same thing if you looked at almost any other study in this area.

There seems to be no upper limit.

And so there's just really not a rationale of saying, well, I'm good enough here.

I'm okay, this is enough.

And if I get any better, it won't really help that much.

You actually do see that in sport performance.

So a classic example here is in the sport of mixed martial arts.

If you'd examine the VO2 maxes of the athletes in that, you would see that it's kind of on an average of about 55 milliliters per kilogram per minute.

And if you get past that,

the benefits of performance continue to go up but even but slightly and once you really start getting past north of 65 it seems to be really no more association between improved performance by that i mean winning fights doesn't mean it is detrimental of course or not advantageous to be in better fitness prior to a mixed martial art fight but we're just saying the rate of increase in performance against the rate of increase in vo2 max starts to taper off

we don't see a similar thing with cardiovascular health.

I'd like to take a quick break and thank our sponsors.
