Question

Quizplus · Accepted Answer

During aerobic exercise, sympathetic stimulation of the heart increases, which causes an increase in heart rate and blood pressure. However, there is also an increase in vasodilation in the muscles being exercised, which helps to maintain blood pressure within a normal range. Therefore, blood pressure changes only slightly during aerobic exercise.
