Cardiac output--the volume of blood the heart pumps in a period of one minute--increases from the typical 5 litres per minute, to up to 40 litres per minute, during strenuous exercise short-term changes in blood flow at rest, the muscles require only about 15 to 20 per cent of the total amount of blood.

Cardiac output is inversely proportional to total peripheral resistance (which is related to mean arterial pressure) venoconstriction refers to the venous system and can't be cardiac output is the product of heart rate times stroke volume therefore cardiac output will increase with exercise read more. 1 explain how regular exercise reduces the risk of heart disease 2 define stroke volume and discuss how stroke volume can be altered explain the effect of changes in stroke volume on cardiac output using the appropriate formula for determining cardiac output. Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload understanding of the applicability and practical relevance of each of these four components is important when interpreting cardiac output values in the.
The increased cardiac output increases the blood flow during maximal levels of exercise increase in cardiac output during exercise cardiac output increases as well as stroke volume the increase in cardiac output means that more blood is pumped around the body allowing more oxygen to be sent to the working muscles. Catecholamine also affects cardiac output catecholamines are the chemicals that are produced during excitement periods these chemicals are released while working, exercising or engaging in any other activity these increases both stroke volume and heart rate which in turn affect cardiac.

See table 2: resting and exercising cardiac cycle length, edv, and esv see graph: resting 2 discuss the effect of venous return and heart rate on exercise edv 3 explain why elite athletes have a lower than normal heart rate, yet have a higher than normal ability to increase cardiac output. • cardiac output is the amount of blood pumped out by each ventricle in one minute • cardiac output can increase markedly to meet the demands placed on our body, whether dashing to catch a bus or riding a mountain bike. Exercise effects on the respiratory system: short- and long-term co2 changes effects of physical activity and sports on the respiratory system mainly depend on changes in alveolar co2 levels here, after analyzing the basics of oxygen transport (changes in co2 and o2 concentrations in the.
