Respuesta :

Answer:

increased maximal stroke volume

Explanation:

Stroke volume is the amount of blood put out by the left ventricle during a contraction. By doing the regular aerobic training one can increase its maximal stroke volume. More the stroke volume of a person less will be its heart rate because more amount of blood will be pumped by the heart in a single time.
