A study in Scotland has demonstrated that CFIDS patients recover muscle strength more slowly than healthy people do. The study by Dr. Lorna Paul and colleagues at Glasgow Caledonian University and the University of Glasgow, was published in the European Journal of Neurology (1999, Vol. 6, No. 1). During a sequence of quadriceps contractions, CFIDS patients and controls showed similar declines in strength, but during a recovery period and at 24 hours later, CFIDS patients were able to produce markedly less force than their initial efforts, while controls had recovered their strength. The results indicated that muscle endurance seemed to be normal in CFIDS patients but recovery from exercise was impaired. The authors wrote that the results could not be due to deconditioning, as the control subjects were similarly sedentary.
