Pathophysiological Effects (Cardiovascular Responses) of Excessive Exercise
Abstract
The cardiovascular system is a complex system that contains the heart, the blood as well as the vasculature. Its purpose is to receive oxygenated blood from the lungs and pumps the oxygenated blood to the rest of the body (organs and skeletal muscles). During exercise there is an increase in the supply of oxygen to the working muscles, this happens so that there is an increased generation of adenosine triphosphate (ATP) to support the continued contraction of the muscles. During this time CO2 is expelled though the heart pumping deoxygenated blood to the lungs.

My measuring the ventricle output it represents the flow of blood throughout the cardiovascular system and the hearts ability to keep up with the body’s demand for blood delivery. Cardiac output is ever changing due to the body’s metabolic needs varying. If strenuous physical activity is done the cardiac output will increase to accommodate the demand for blood flow to the skeletal muscles.
Heart rate is affected primarily by the sympathetic nervous system (increases HR) and the parasympathetic nervous system (decreases HR). These systems change the depolarization and repolarization of the pacemaker cells of the conducting system.
Stroke volume is the amount of blood that is ejected from the ventricles with each heart beat and is determined by three important factors: Preload, which is the amount of blood that returns to the heart during diastole (relaxation), as more blood returns into the heart the more blood is able to be ejected. Afterload is the pressure that counters the ejection of the blood in the ventricles and is known to be equal to the systemic arterial pressure, reflected by the mean arterial pressure (MAP). As all factors are equal is decreases stroke volume and increase
