People with chronic fatigue syndrome or rheumatoid arthritis both experience exercise intolerance. A recent study suggests that both similar and different processes are at work in both.
Invasive exercise study uncovers two different kinds of chronic fatigue syndrome. One is characterized by low heart outputs associated with reduced preload and blood pooling. The other is probably caused by shunts which propel blood away from the muscles. Approximately 30% of ME/CFS patients have small fiber neuropathy as well. Deconditioning is not causing the abnormalities found.
How a person with chronic fatigue syndrome (ME/CFS) improved their health and quality of life by pacing using heart rate and heart rate variability monitoring
The exercise physiologists at the Workwell Foundation are pretty darn good at providing thought provoking case reports. A couple of years ago, a Workwell case report indicated that a very ill ME/CFS patient was able, using Workwell’s heart rate-based exercise...
Exercise affects far more of the body than expected. A blood test that predicts aerobic functioning and other insights from an intensive exercise study could ultimately help explain chronic fatigue syndrome.
Poor oxygen uptake from the red blood cells could help explain the exercise issues in chronic fatigue syndrome (ME/CFS). Mitochondrial problems or hyperventilation contribute to the oxygen uptake problem.
