During exercise cardiac output increases as a result of an A

During exercise cardiac output increases as a result of a(n) A) increase in heart rate. B) increase in stroke volume. C) increase in heart rate and stroke volume. D) increase in parasympathetic stimulation. E) both C and D are true.

Solution

answer is (c) because cardiac output -- increases during exercise because your heart is trying to meet your muscles’ need for increased levels of fuel. This fuel comes in the form of blood and oxygen, and is required for your muscles to keep going. While technically, the formula for determining your cardiac output is \"heart rate X stroke volume,\" for everyday practical purposes, monitoring your heart rate during exercise is generally more common. This is in part because changes to either the heart rate or stroke volume will have a domino effect in impacting all related components.
