As the compulsion to sleep intensifies, the ...
One of the first definitions of ME/CFS, the Holmes Criteria published in 1988, does not use the term post-exertional malaise but describes prolonged fatigue after exercise as a symptom. [7] The term was later used in a 1991 review summarizing the symptoms of ME/CFS.
Fatigue in a medical context is used to cover experiences of low energy that are not caused by normal life.

When people with ME/CFS exercise on consecutive days, their performance declines on the second day, unlike those with unexplained chronic fatigue (ICF). Objective signs of PEM have been found with the 2-day cardiopulmonary exercise test. [52] People with ME/CFS have lower performance compared to healthy controls on the first test.
Researchers worry that people who exercise regularly might be sedentary to a harmful degree during the rest of the day because they think of their day in two blocks, active time and resting time ...
The combination of an inappropriate rapid heart rate response to exercise with heavy or rapid breathing is known as an exaggerated cardiorespiratory response to exercise. [3] Due to the confusion between muscle fatigue and muscle weakness, there have been instances of abnormal muscle fatigue being described as exercise-induced muscle weakness.
During intense exercise, lactate has been estimated to provide a third of the brain's energy needs. [39] [42] There is evidence that the brain might, however, in spite of these alternative sources of energy, still suffer an energy crisis since IL-6 (a sign of metabolic stress) is released during exercise from the brain.
