Deconditioning

Deconditioning is often seen in the elderly due to bed rest and inactivity. Risk factors are illness, disability, chronic disease, medical and psychosocial circumstances.

Deconditioning is thought to be the reason for inactivity in ME/CFS by those holding the theory ME/CFS is a mental health issue and they claim patients have a "fear of exercise" instead of believing patient's claims of not being able to exercise or exert themselves.

Notable Studies

 * Unexplained exertional dyspnea caused by low ventricular filling pressures: results from clinical invasive cardiopulmonary exercise testing


 * Cort Johnson breaks down the study in Health Rising. Article Heading: Not Deconditioning "The study also indicated neither deconditioning or a reduced maximal effort, both of which have been suspected in ME/CFS, play a role in the exercise intolerance found. In fact, deconditioned people, ironically, exhibit an opposite finding (increased as opposed to decreased filling pressures) to that found in this study."
