A series of pressure sensitive cells called barorceptors constantly regulate blood pressure as part of the barorceptor reflex, a homeostatic mechanism for maintaining blood pressure. These barorceptors are located in the carotid artery, the wall of the ascending aorta and in the aortic arch.
When exercising the systolic blood pressure will increase in relation to exercise intensity, this is a result of an increase in cardiac output. The diastolic pressure will see little or no change apart from when performing high resistance static exercises, which may give rise to large increases.
Blood Pressure change during Exercise
The resting blood pressure levels have been proven to see reductions following aerobic exercise or resistance training. During an exercise period of 5 to 25 weeks you could see a reduction in resting systolic pressure of 11mm/Hg and a decrease of 8mm/Hg in the resting diastolic pressure.
The baroreceptors monitor blood pressure and provide information to the cardiovascular control unit in the brain, from here the pressure is compared to the bodies preset value that the body normally experiences.
