Abstract

Previous studies in the chronic phase of hypertension (SHR ~ 3 months) have shown the effectiveness of aerobic training (T) to reverse / correct some of the functional deficits, showing in addition that these changes were related to plastic and functional adaptations of central autonomic pathways. Nothing is known about the potential benefits of exercise training started early, in the pre-hypertensive phase. In the present study we sought to analyze in the young SHR (~ 4 weeks old at the beginning of the protocols) and their normotensive controls the effects of aerobic training on the functional responses of the cardiovascular system (baseline blood pressure and heart rate, baroreflex sensitivity, sympathetic and parasympathetic tone to the periphery, variability of blood pressure and heart rate) and the associated changes on gene and protein expression in different autonomic areas integrating bulbar and suprabulbar cardiovascular control.
