After reading this article, imagine a scenario in which the physiological processes that strengthen or promote mitochondrial biogenesis after exercise are dysfunctional.

I wonder what such a disease process would look like?

It's certainly not my experience. Whilst limited duration of some form of exercise (done during "good" times) definately helps me physically when the bad times come it does nothing to help me cognitively, to the extent that at 45 I'm being investigated for dementia.
