Exertion is the physical or perceived use of energy. Exertion traditionally connotes a strenuous or costly effort related to physical, muscular, philosophical actions, and work,[1] resulting in the generation of force, initiation of motion, or in the performance of work.[2] It often relates to muscular activity and can be quantified, empirically and by a measurable metabolic response.[3][4]
Exertion in ME/CFS[edit | edit source]
Only a minimal amount of exertion causes a marked increase in symptoms in people with ME/CFS[5], for instance chronic fatigue, chronic pain, cognitive dysfunction (e.g., brain fog), flu-like symptoms, muscle fatigability, unrefreshing sleep, and more, this is known as ME/CFS's hallmark symptom post-exertional malaise (PEM).[5][6][7] Depending on a patient's disease severity exertion capabilities is different and results in varying symptoms and degree of symptom severity.[8][9] Physical or mental exertion can trigger PEM.[10][11]
This post-exertional malaise is not limited to just musculoskeletal pain or fatigue, and does not occur in illnesses like depression, multiple sclerosis, or systemic lupus erthematosus or rheumatoid arthritis.[5]
Intolerance to exertion and exercise was built into the renaming of ME/CFS by the National Academy of Medicine (NAM) in the 2015 Institute of Medicine report (IOM report) where the name Systemic Exertion Intolerance Disease (SEID) was coined.[12][9]

The severe exacerbation of symptoms following exercise, as seen in CFS patients, is not present in other disorders where fatigue is a predominant symptom such as depression, rheumatoid arthritis, systemic lupus erythematosus, or multiple sclerosis. 10,11
