Abstract
In animals, the J reflex evoked by pulmonary C fibers provides potent inhib ition of limb muscles and would act to limit exercise. However, recent work shows that although activation of these fibers causes severe respiratory d iscomfort, it does not impair the output of limb motoneurons to voluntary, reflex, or locomotor drives in awake humans.
