Re: Re: BMI and IHD running and sodium

[Guest guest]

I don't dismiss running or one's desire to do it, but I think one should get a dr's approval before starting and I think walking is enough aerobic, per the AHA.

Subjectively, we can probably get more people to walk than run.

I've increased my sodium intake to just under 3 grams. There ARE other side effects one can't find in an article, peer reviewed or not.

I'm not convinced either will extend lifespan, especially for humans that started late in life.

Do you have at hand an article that shows risk versus running like the BMI/IHD. I have not found such yet.

Regards.

With the recent run of hot weather I had to start dosing with salt when I started to get cramping again (I don't need to supplement during winter months). I rarely pay much attention to the %BF on my tanita but I did notice between Wednesday and today my #BF dropped from 14%+ to 12%+ while my weight varied less than 1/2 #. Over the last few days I probably consumed an extra 3+ G of salt (mixed in water). Since the tanita works on electrical conduction this seems like one of several potential error sources.

Agreed walking is OK, just takes longer to get where I want to go.. :-)

I am not aware of studies of (human) running wrt longevity but do recall

reports of CR'd rats running on their wheels. I try not to read too much

into animal behavior under such unnatural conditions, so wouldn't even

try to infer something from such reports for humans.

I have seen a recent discussion of aerobic exercise being protective wrt

decline of mental function. If one plans to live a long time it would be

nice to keep more of our marbles..... Admittedly this is just a QOL

issue but IMO rather important.
