Relative Contribution Of Cardiac And Peripheral Blood Flow To Blood Pressure In Humans: The Role Of Metaboreceptors, Gabriel B. Carlota, Matthew Pizano, Stephanie S. Wang, Areum K. Jensen
Relative Contribution Of Cardiac And Peripheral Blood Flow To Blood Pressure In Humans: The Role Of Metaboreceptors, Gabriel B. Carlota, Matthew Pizano, Stephanie S. Wang, Areum K. Jensen
International Journal of Exercise Science: Conference Proceedings
The autonomic nervous system plays an essential role during exercise by adjusting cardiac output (CO) and redistribution of peripheral blood flows. One primary mechanism responsible for such alterations is the exercise pressor reflex (EPR), a feedback mechanism from contracting muscles via mechano- and metabo-receptor activation. The EPR adjusts the circulation by evoking reflex increases in sympathetic outflow to the heart and the vasculature, eventually increasing blood pressure (BP) during exercise. Previous studies suggested that relative contribution of cardiac and peripheral blood flow to regulate BP may depend on various factors (e.g., sex, health status). Thus, we thought to investigate if …
