That is to say, sedentary behavior in older persons may not, in itself, give rise to a greater risk of long-term "disability."
That's interesting. The main difference between your findings and those of the study is that some prof got a government grant, and you did not.
Oh, and the other difference is that you are probably correct, while the study funded by grant is not.
While you were thinking and typing this, so was I! See below.
“It seems at least as likely that older persons who already suffer from conditions that will ultimately manifest as ‘disability’ will, as a consequence, be more inclined to be sedentary.”
Hmmm...I might have to dash off a note to my HS classmate, Rowland (aka “Bing”) Chang, MD pointing this out!
I have a pretty severe case of ME/CFS and I must put extreme limitations on sustained activity of any kind beyond about 2 minutes or I will suffer an even more debilitating relapse lasting up to a week.
Rather than walking around while talking on the phone as suggested by this article, I must lie down to avoid the combined mental/physical stress of the mental activity of phone social interaction with the physical effort of breathing while talking. Pretty pathetic, huh?
I make sure that every day I walk up 4 flights of stairs (65 steps) to my apartment, which I can do in 2 minutes if I do is slowly and deliberately. And I do 5 each of push-ups, back-lifts and jackknife sit-ups.
In addition I eat as little as possible to avoid weight gain with a very high proportion of chicken and fish protein in my diet. I weigh the same now as I did 13 years ago when I became disabled from ME/CFS.
So according to this study I am still DOOMED! Oh joy.
