Blood Pressure & Cardiac Output 

BLOOD PRESSURE

There are two components to the measure of blood pressure:

Systole - TOP NUMBER It is the pressure in the ventricles when they are contracting and pushing blood out into the body. 

Diastole - BOTTOM NUMBER It is used to describe the pressure in the heart when the ventricles are relaxed and are being filled with blood. Indicator of peripheral blood pressure (the blood pressure in the body outside the heart).

FYI: The normal range of pressure during systole is about 120 mmHg and during diastole is about 80 mmHg

120/80mmHg

The table above presents data for a healthy trained 80 kg male at rest and performing two different actions (running fast, a dynamic activity; trying to lift a very heavy object, static but very high forces), as well as resting data for another untrained and unhealthy individual. 

Answer the following Questions based on the Chart: 

1.   What effect does dynamic exercise have on blood pressure? 

2.   What effect does static exercise have on blood pressure? 

3.   Why is one higher than the other? 

4.   What difference is there between the two participants at rest? 

5.   Elevated blood pressure is known as hypertension. Why would a higher blood pressure          present a challenge that may result in health complications? 

CARDIAC OUTPUT

The amount of BLOOD that our HEART puts out per MINUTE
