: number of animals; MAP: mean arterial pressure; SMW: soleus muscle wet weight; CS: citrate synthase; MAP: mean arterial pressure; NE: norepinephrine; WKY-Sed: Wistar-Kyoto-sedentary; SHR-Sed: spontaneously hypertensive rat-sedentary; WKY-ExT: Wistar-Kyoto-exercise training; SHR-ExT: spontaneously hypertensive rat-exercise training. Data are mean ± SE. Values for MAP and HR were obtained in anaesthetized rats. MAP was measured by catheterizing femoral artery. versus WKY-Sed. versus SHR-Sed.
