title: [Hemodynamic reactions in cats exposed to physical loading].
abstract: Cats were trained to pull with a force equal to 50--200% of their body weight. The mean arterial pressure and heart rate increased during the exercise. Pressor response was due to the increase of peripheral vascular resistance, as the cardiac output was constant or even decreased. Blockade of vegetative nervous system led to a 2--3 fold decrease of the pressor response. The conditioned stimulus for "work" had no effects in intact cats, but evoked obvious pressor response in curarized cats. Mechanisms of the vegetative changes during static work are discussed.
