Eductional Objective: During exercise, the blood supply to the muscle during periods of strenuous activity is reaching around 85% of cardiac output. Mean blood pressure doesn't significantly be affected due to increase sympathetic stimulation during exercise despite of increasing cardiac output and splanchnic vasoconstriction. vasodilation within active skeletal muscles significantly decreases the total systemic vascular resistance.
