Central command may predominate in rapid HR acceleration at exercise onset; hypothesis-generating for autonomic mechanisms in health and disease.
Does volitional cycling or passively induced cycling with electrical stimulation decrease R-R interval compared to rest in healthy volunteers?
Both central command (volitional cycling) and muscle-heart reflex (passive cycling with electrical stimulation) contribute to instantaneous heart rate increases at the onset of dynamic exercise.
Williamson et al. (1995) studied this question.
