Why does diastolic blood pressure remain relatively unchanged despite changes in exercise intensity

including the amount of blood in your body (blood volume), the volume that your blood pumps into your arteries with each beat (stroke volume) and how often your heart is pumping new blood into the arteries (heart rate). To meet your muscles increased oxygen demand, all these factors increase during exercise. To create more space for the increased blood flow during exercise, your arteries dilate so diastolic blood pressure remains the same.......
Diastolic blood pressure is the pressure on your artery walls between heartbeats. Diastolic pressure usually is described in combination with systolic pressure (the pressure exerted on your arterial wall during the heart's contraction), and is the lower of the two numbers in your blood pressure reading. In healthy individuals, diastolic blood pressure stays the same during cardiovascular exercise.

There are several factors that affect diastolic blood pressure, including the amount of blood in your body (blood volume), the volume that your blood pumps into your arteries with each beat (stroke volume) and how often your heart is pumping new blood into the arteries (heart rate). To meet your muscles' increased oxygen demand, all these factors increase during exercise. To create more space for the increased blood flow during exercise, your arteries dilate so diastolic blood pressure remains the same.
