I don’t know if the info below is derived

from the same JAMA study you mention (my computer couldn’t access the

link above) or if yours was a follow-up study to the one below, but this

article explains the importance of exercise from a JAMA study in layman’s

terms – sorry it’s from 2001.

Hi Kathy:

This (from Dr. Mirkin) all sounds wonderful, thank you for posting

it. I was unable to access the January 12 2001 item they seem to

have based that piece on. Does anyone have a reference for it,

please?

But it is all inconsistent with the fact that the New England

Centenarian Study's listing of factors common to their centenarian

subjects does not contain anything related to exercise. When I asked

them why, their reply was that there was no consistent pattern either

of amount of exercise or by type. Some had taken considerable

amounts exercise, others none at all. And for those who had

exercised, the types of exercise were all over the map, they said.

Yet the subjects were all over 100.

Seeing at least the abstract of the JAMA paper might help.

Also bear in mind that most of the stuff I have seen regarding the

claimed benefits of exercise indicate that most of the benefit is in

protection against CVD. If that is the case then exercise may not

add much on top of the benefits derived from CRON, the practitioners

of which already exhibit negligible CVD risk factors (WUSTL). And

more exercise does require the expenditure of more calories, which we

can all agree may not be helpful.

It seems to me that the jury is still out on this one. I could be

swayed either way by more definitive evidence of benefits, especially

for immunity and cancer, as suggested in Dr. Mirkin's piece that you

kindly posted.

Rodney.
