The paper's discussion contains this statement:

In addition, studying masters athletes partially limits the applicability of these data to the general population of aging adults who do not aggressively exercise 4 to 5 times per week.

It's unfortunate that such a statement won't make it into popular treatments, but the paper doesn't get very far out over its skis.




My point is they are not sampling from genpop And they are sampling Different populations with age rising. I've met quite a few fit 60 yr olds, but have never seen a that fit 80 yr old.
