Interesting, thanks! I know a lot of people who hate taking statins and hate exercising, but do both. I wonder which they will quit?
Personally I have been on Vytorin for years to keep my cholesterol down, and it contains Zocor, the statin they studied. I don't have any problems with statins or exercise (other than the ridiculous, exorbitant, infuriating, insane cost of Vytorin). I feel I gain at least as much from exercise now as I did before I started on statins. Actually more, I suppose, because despite being 7 years older now I am stronger than ever.
(Edited to add: Ah - - I see that they only looked at aerobic fitness, not strength. Well, OK, even though I have been improving my time and speed on the elliptical quite a bit, still I am the worlds' worst at cardio exercise. But then, the same was true for me in high school so nothing new there.
Seriously, I don't see the difference there, either.)
I love my workouts at the gym, and feel I get a lot out of regular exercise. I don't see myself ever giving up regular exercise unless some serious health reason arises. Also I don't see myself giving up statins unless my cholesterol lowers all by itself (and my doctor says that is unlikely to happen because there is a hereditary component).
If the study is valid, then I suspect that there are a lot of individual differences in response to statins.
