Cardiovascular Reflexes Activity and Their Interaction during Exercise
نویسندگان
چکیده
Cardiac output and arterial blood pressure increase during dynamic exercise notwithstanding the exercise-induced vasodilation due to functional sympatholysis. These cardiovascular adjustments are regulated in part by neural reflexes which operate to guarantee adequate oxygen supply and by-products washout of the exercising muscles. Moreover, they maintain adequate perfusion of the vital organs and prevent excessive increments in blood pressure. In this review, we briefly summarize neural reflexes operating during dynamic exercise with particular emphasis on their interaction.

Neural control of the cardiovascular system during exercise. An integrative role for the vestibular system.
Precise regulatory signals are required in order to adjust the cardiovascular and respiratory systems to meet the demands of exercise. Two neural mechanisms, central command and a reflex originating in contracting muscles, are known to play a large role in exercise-associated adjustments in cardiovascular and respiratory activity. The extent to which other regulatory reflexes, such as vestibulo...
