WRITE DOWN THE POINTS… Learn, define and find out your resting HEART RATE Understand what STROKE VOLUME and CARDIAC OUTPUT are Learn how these are affected by exercise HEART RATE This is the number of times your heart beats per minute Lets now find out our resting heart rates The average heart rate is about 70 beats per minute • What is your heart rate? • What is the average of the whole class? STROKE VOLUME This is the volume of blood pumped out of the heart by each ventricle during one contraction This increases once exercise commences because heart chambers fill and empty more due to stronger contractions of the heart CARDIAC OUTPUT This is defined as the amount of blood ejected from the heart in one minute After doing the reading in section 2, calculate your estimated cardiac output using the equation… Heart rate x stroke volume = cardiac output
