Why and how does blood pressure change during steady state exercise?

Answer 1

Stroke volume: Stroke volume is the amount of blood ejected per beat from left ventricle and measured in ml/beat. Stroke volume to its highest during sub maximal exercise and doesn't increase during maximal exercise. The greatest increase of stroke volume increases in the transition from rest to moderate exercise, during maximal exercise stroke volume doesn't go over its peak of 120 - 140 per minute Starling's law states that the stroke volume is limited towards the venous return, of which is the amount of the blood that is available to enter the left atrium and pass to the left ventricle

Answer 2

When you exercise, you need more energy, in order for our muscles cells to function. So more aerobic respiration occurs to provide our cells with oxygen. Oxygen is transferred through blood. So if our heart rate and breathing rate both increase in order to provide our muscles with oxygenated blood, blood pressure increases as well because it transfers oxygen quicker. However this happens during the steady state exercise. After this exercise blood pressure returns to the normal levels of each person.
