Abstract
The results suggest that when partial curarization induces a disproportion between the signal from central command and that from exercising muscles, the larger signal arising from central command determines the magnitude of the cardiovascular responses. The centrally generated heart rate response is in part caused by vagal withdrawal. However, the blood pressure response cannot be attenuated by the sole use of alpha- or beta-receptor adrenergic blockade or combinations of these with atropine. This suggests that there may be greater redundancy in the autonomic control of blood pressure than in the vagal control of heart rate associated with central command during static exercise in man.
