[Structure of hemodynamic responses in the central command to move].
Cardiac and vascular components of the hemodynamic response to "central command" to the skeletal muscles in immobilized decerebrated cats using an experimental model of "fictitious scratching" revealed that activation of the m. gastrocnemius increased blood pressure by 57 mm Hg, whereas cardiac output and blood flow in the common iliac artery changed insignificantly. The maximal increase of the blood flow in common iliac artery depended mainly on the stimulation of beta-adrenoreceptors by circulating catecholamines. The adaptive cardio-vascular responses during "central command" to skeletal muscles seem to depend mainly on the elevation of peripheral vascular resistance, there being no specific vasodilator influences on blood vessels of the muscles receiving the "central command".
