That doesn't speak for or against the view that the only type of exercise that
increases bone mass or prevents its erosion is load-bearing/impact
(weight-bearing/resistance).
JE>> they aren't doing load-bearing/impact exercise.
AA>> A.A. That's the conventional wisdom.
I thought you were saying that the conventional wisdom was that any exercise
helped, but that Kolata said it didn't; from what you later wrote, I thought
you were also saying she said load-bearing/impact exercise had a positive
effect.

sorry haven't got the time

You did. Anyway that she didn't say anything about it doesn't mean it isn't
relevant.

Then she omits important factors (such as nutrition)

who's the "they"?
