Cardiovascular effects
Cardiovascular response to changes in body position and physical activity
Abstract The aims of the experiment were to investigate the cardiovascular responses to changes in body position and exercise on human blood pressure using an electronic (automated) blood pressure meter. Moreover, monitoring changes in blood flow and blood pressure in the body while sitting, lying supine, standing, as well as engaging in low intensity exercise of walking and medium intensity exercise of squatting after 2 minutes. The main conclusions of the experiment were that systolic blood pressure, mean arterial blood pressure, and pulse rate increase during levels of physical activity compared to the measurements read at the initial resting positions, whereas the diastolic blood pressure remained fairly constant throughout the different measurement readings.
Introduction The blood that circulates throughout the body maintains a flow and pressure. Blood pressure is the force of blood against a blood vessel wall. Blood pressure is needed to push the blood along the blood vessels to reach the various tissues of the body (5). The nervous system can change the flow and pressure based on the particular needs at a given time, such as during exercise where blood pressure and blood flow is increased (6). In the systemic heart, blood starts in the heart and is pumped from the left ventricle through the aorta to the tissue beds of the body. The blood then returns to the heart from the body through the systemic veins. It returns to the right atrium, and is pumped to the right ventricle. From the right ventricle the blood is pumped through the pulmonary arteries to the lungs, where gas exchange occurs. The blood is returned to the heart through the pulmonary veins to the left atrium. Then it is pumped to the left ventricle to complete the circuit (1, 2). The pressure at which the heart pumps blood throughout the body must be able to overcome the resistance in the circulatory system
