Move it or lose it? Supposing for one second that this disease has

dietary ogigins, would not the physiological stress occasioned by

exercise just speed up its development if dietary defficiencies remain

uncorrected? Just like calcium supplementation, exercise just does not

seem like the adequate answer to this problem.

Actually, there are many studies (I'll attach a summary article below)

that have established over and over that physiological stress on the

bones is *necessary* to strengthen the bones. That's why astronauts

in space need to keep exercising (strengthening bones and muscles).

Cochrane Review on exercise for preventing and treating osteoporosis

in postmenopausal women.

You're right that dietary deficiencies still need to be corrected in

order to improve bone density, but you are incorrect about physiologic

stress being worse for bones under those conditions. Obese people

often have lousy diets and very strong bones.

Hi folks:

And also don't forget the study posted here some months ago which

showed that rats that SWAM for exercise - generally not considered

weight-bearing - also had much improved bone mass.

It is far from clear to me that I have a good grasp of the

fundamental principles involved in this issue. (Is it the stress of

weight on bones, or flexing of muscles, or something else no one has

thought of that explains the effect?). But yes, exercise has been

shown quite often to improve bone mass, as has taking supplements of

calcium/vitamin D, of course. (Posted here often).

The most interesting new (to me) information I have read on this

topic recently was the Mirkin email item I posted here which claimed

that stem cells in bone can either produce bone cells or fat cells.

This seems like this might turn out to be a big issue. If correct.

If anyone finds more information on this please post.

Rodney.

Interesting, I remember reading that it also will tend to raise the 5 of

fat in a human when they exercise in a pool, although it was speculated

that that was related to pool temperature.

I am in the process of building a new house that will probably have a

pool, primarily for exercise.

I recall the pitcher, Sandy Koufax, who retired because of arthritis - x-rays of his left pitching arm showed bone wall thickness like twice that of the right arm. I think that's do the muscle pulling on the bone - a force balance system. So I conclude that the bone builds to carry the stress of the muscle on the bone, regardless of the exercise.

Swimming seems to me the same type of exercise maybe not as intense, but may be better for exercising all muscles.

So maybe if I pick up 100# over my head it strengthens all the bones in the path, but once it's there the strain on the bone takes over. Implying to me maybe the weight of a person standing is not as good as using the muscles as in walking, etc.

Astronaut exercises are dynamic, as I recall.
