Suggests modality-specific cerebral metabolic responses to exhaustive exercise; leaves open relevance for clinical exercise testing or rehabilitation protocols.
Does exhaustive arm cranking compared to leg exercise differentially affect the cerebral metabolic ratio of O2 to (glucose + lactate)?
Exercise decreases the cerebral metabolic ratio when conscious effort is required, but the reduction is less pronounced during arm cranking compared to leg exercise.
Dalsgaard et al. (2004) studied this question.
