3. Definitions Blood pressure - ‘The of force at which the blood passes through the blood vessels.' Heart rate - 'The number of times the heart beats per minute' Stroke volume - ‘The amount of blood pumped out of the heart during one contraction' Cardiac output - ‘The amount of blood ejected from the heart in one minute'

5. Resting heart rate The average heart rate when we are at rest is 60-80 BPM Your resting heart rate can be a sign of fitness. People with high cardiovascular fitness have lower resting heart rates as the body is more efficient at transporting the blood around the body.

6. Systolic/Diastolic Systolic – The pressure of the blood when the heart contracts Diastolic- The pressure of the blood when the heart relaxes Systolic/Diastolic http://www.youtube.com/watch?v=06iQlVMS B34

7. Task You will take you pulse for 15 seconds Take this number and multiply by 4 to get your BPM

8. Task You are going to do 1 minute of star jumps star jumps 1min Retake you pulse List: what has been the immediate effects of this small amount of exercise on you

9. Heart rate monitoring Effects of exercise on the cardiovascular system 10 An ECG (electrocardiogram) machine will show you what your heart rate looks like.

10. Short-term effects of exercise on the cardiovascular System Effects of exercise on the cardiovascular system 11 Heart rate increases Adrenalin released Breath faster and deeper Body Temperature increases Blood Pressure increases Sweating

11. Long-term effects of exercise on the cardiovascular system Effects of exercise on the cardiovascular system 14 Size and Volume of the heart increases Lower Resting Heart Rate Lower Blood Pressure Increased Stroke Volume Increased Cardiac Output More Capillaries

12. The cyclist Miguel Indurain, five times Tour de France winner, had a resting heart rate of 28 beats per minute, one of the lowest ever recorded in a healthy human. Effects of exercise on the cardiovascular system 18
