Blood Pressure

What is diastolic blood pressure?

The force exerted by blood on arterial walls during ventricular relaxation.

What is the normal range for diastolic blood pressure in a healthy adult?

80 mmHg.

What is systolic blood pressure?

The force exerted by blood on arterial walls during ventricular contraction.

What is the normal range for systolic blood pressure in a healthy adult?

120 mmHg.

What unit measures the force exerted by circulating blood on arterial walls?

mmHg

How does dynamic exercise affect systolic blood pressure?

Systolic BP increases and can rise to 200 mmHg during exercise.

Does diastolic blood pressure change during dynamic exercise?

Diastolic BP remains constant

What do muscles move through?

a specific range of movement

What does dynamic exercise involve?

repetitive movements that promote efficient blood flow allowing blood vessels to relax

What does the dilation of the blood vessels mean?

keeps the diastolic BP from rising too much

What happens to both systolic and diastolic blood pressure during static exercise?

Both systolic BP and diastolic BP increase.

What is the muscular movement in static exercise?

muscles length doesn’t change and joints don’t move

What does the constant contraction of muscles limit and increase?

limits blood flow and increases pressure

What does the body interpret this as?

a higher resistance rate so both systolic and diastolic pressures increase

What is vascular shunting?

The process of redistributing blood flow to areas where it is most needed during exercise.

What happens to blood flow during exercise?

Blood flow increases to active muscles to meet oxygen and nutrient demands and to remove heat and waste products.

How much more blood flow is directed to active muscles during exercise?

Up to 25 times more blood flow to active muscles.

What happens to arterioles during exercise?

Arterioles dilate to supply more blood to the muscle.
