Chronic fatigue syndrome: matching exercise to symptom fluctuations.
The major symptom of chronic fatigue syndrome is extreme fatigue and an increase in fatigue following exertion. Many patients reduce physical activity to avoid such fatigue and thus become increasingly weak and less fit. Exercise testing does not exacerbate symptoms. Even though a fair amount of variability exists in symptoms from one day to another, low- to moderate-intensity, intermittent exercise therapy appears to improve functional capacity and reduce fatigue and other symptoms.
