Are Stamina and Fatigue Polar Opposites? A Case Study

摘要

Most individuals with Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS) (), Myalgic Encephalomyelitis (ME) (), and chronic fatigue syndrome (CFS) () indicate that they experience fatigue and sharp decreases in energy levels, which hinder the ability to engage in physical activities (). However, there are some individuals who reduce activity engagement in order to avoid a worsening of symptoms; thus these individuals may endorse lower levels of fatigue. Accordingly, those with low levels of fatigue but low endurance/stamina might be inadvertently excluded from some criteria based on the fatigue requirement. The current study serves as an exploration of the relationship between fatigue and stamina and the effects of these constructs on illness symptomology and their implications for assessment and diagnosis.
