ventricular contraction. Cardiac output is the volume of blood ejected from the left or right ventricle into the aorta or pulmonary trunk per mind. Cardiac output equals stroke volume times the heart rate; therefore‚ if the anything that decreases cardiac output‚ also decreases blood pressure because there is less pressure on the vessel walls. An increase in cardiac output results in an increase in blood pressure. Anything that affects heart rate or stroke volume affects cardiac output and blood pressure

Exercise has a major impact on the cardiovascular system and its efficiency in the human body. There are many concepts which need to be examined to understand exercise and the cardiovascular system‚ such as systolic and diastolic blood pressure‚ cardiac output‚ total peripheral resistance‚ and physiological pathways. According to the European Journal of Cardiovascular Prevention and Rehabilitation‚ exercise provides a change in the effectiveness of the cardiovascular system‚ whether over a short or
