deconditioning

Abstract: Patients with long COVID and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) suffer from a reduced exercise capacity, skeletal muscle abnormalities and post-exertional malaise (PEM), where symptoms worsen with cognitive or physical exertion. PEM often results in avoidance...

This is the preprint. Go to post #186 for the published version. Abstract Myalgic Encephalomyelitis (ME; sometimes referred to as chronic fatigue syndrome) is a relatively common and female-biased disease of unknown pathogenesis that profoundly decreases patients' health-related...

Just wrote a blog about what deconditioning looks like and how it differs from ME/CFS. https://mecfsskeptic.com/what-does-deconditioning-look-like/ Interestingly the best evidence on deconditioning comes from NASA bed rest studies. Head-down bed rest was used as a proxy for the low gravity...

Disuse-Induced Muscle Fatigue: Facts and Assumptions Sergeeva, Xenia V.; Lvova, Irina D.; Sharlo, Kristina A. Skeletal muscle unloading occurs during a wide range of conditions, from space flight to bed rest. The unloaded muscle undergoes negative functional changes, which include increased...

I used to read full papers voraciously and wrote over 100 e-letters along with getting some letters published. Following a discussion about risk factors for CFS today, I was reminded of the following in response to some spin in a paper by Peter White et al. =========...

Abstract Purpose: Previous studies in chronic fatigue syndrome (CFS) have reported reductions in maximal oxygen uptake (VO(2max)), yet often the testing procedures have not followed accepted guidelines, and gender data have been pooled. The present study was undertaken to reevaluate exercise...

Background: Orthostatic intolerance (OI) is a core finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Deconditioning is often proposed as an important determinant for OI. Deconditioning can be objectively classified using the predicted peak oxygen...
