title: Stopping Exercise: Role of Pulmonary C Fibers and Inhibition Of Motoneurons.
abstract: In animals, the J reflex evoked by pulmonary C fibers provides potent inhibition of limb muscles and would act to limit exercise. However, recent work shows that although activation of these fibers causes severe respiratory discomfort, it does not impair the output of limb motoneurons to voluntary, reflex, or locomotor drives in awake humans.
