The increase in size of the heart enables the left ventricle to stretch more and thus fill with more blood. The increase in muscle wall thickness also increases the contractility resulting in increased stroke volume at rest and during exercise, increasing blood supply to the body.
What is the cardiovascular adaptation to exercise?
The functionally most important adaptation is the improvement in maximal cardiac output which is the result of an enlargement in cardiac dimension, improved contractility, and an increase in blood volume, allowing for greater filling of the ventricles and a consequent larger stroke volume.
How is the cardiovascular system affected by exercise?
Improves the muscles’ ability to pull oxygen out of the blood, reducing the need for the heart to pump more blood to the muscles. Reduces stress hormones that can put an extra burden on the heart. Works like a beta blocker to slow the heart rate and lower blood pressure.
