Objectives

• YOU will be able to:– Localize your pulse and measure your heart rate.– Understand the importance of monitoring their heart rate.– Learn the importance of moderate to vigorous physical

activity – Notice a change in breathing intensity with activity– Define RPE– Learn the rate of perceived exertion chart and describe at

which level of the chart the activities performed correspond to.

Your Pulse and Your Heart Rate

• What is your pulse?– Your pulse is the palpable rhythmic expansion of an

artery produced by the increased volume of blood pushed into the vessel by the contraction of the heart.

• Why does your pulse increase with exercise?– The harder you work the faster your heart beats

because it has to send oxygenated blood (blood rich in oxygen) to the muscles to help them continue to work.

• Different locations to palpate your pulse:– Brachial artery - Carotid artery - Femoral

artery– Radial artery - Popliteal artery - Ulnar artery

Your Pulse and Your Heart Rate con’t

• How to find and measure your pulse– Use your index finger and middle finger to

lightly palpate either carotid or radial artery.– Subject’s arm must be relaxed– Subject can be sitting or standing up

straight– When you find the pulse measure it for a

total of one minute.– You can check your pulse before and after

activity to see the difference.

Rate of Perceived Exertion

• Rate– The amount of something per given amount of time.

• Perceived– What you personally think you observe/ educated

guess.

• Exertion– The energy or work you do

• RPE– The amount of energy you think you do in a given

amount of time.

• Chart and Cardio worksheet

Physical Activities• Walking and talking with a partner around the basketball

courts– Calculate HR and RPE– Answer question

• Play tag– Remember to play hard, play safe and play fair– Calculate HR and RPE– Answer question

• Run, jog, or jump rope for 2 minutes without stopping– There is no minimum number of laps but want them to

work at a level of 7 RPE– Calculate HR and RPE– Answer question

Closure• Turn to someone around you and

talk about what you noticed about your HR and RPE.

• What are some similarities?• What are some differences?

Heart Disease

Workout Time• What is a workout?• 30 minutes of continuous activity.• Heart rate must be elevated for

the entire 30 minute time span.

Target Heart Rate (THR)

• Why is THR important?• Targeting your heart rate is a

more effective way of working out.• Effectively track the intensity of

your workout routine.• Helps to better plan workouts that

reduce calories without tiring out or injuring yourself.

Target Heart Rate (THR)

• Reduce resting heart rate

• Improve circulatory system

Calculating Your THR• Take your age • Subtract it from 220• The sum is your Max heart rate

(HRmax)• Example: Age= 35• 220 – 35= 185• 185 is the HRmaxThis is an estimate pending other factors

American Heart Association

• Target Heart Rate Chart• http://www.americanheart.org/pre

senter.jhtml?identifier=4736

F.I.T.T. Principle• Frequency- how

often you exercise• Intensity- The

amount of effort you put into your workout (easy, medium, hard)

• Time- How long each workout last

• Type- type of exercises you will be doing

Caution!• Consult your doctor before beginning

any sort of rigorous workout regiment• When using your THR start slow and

begin with 50% of your max HR.• Once the work out becomes easier,

increase your intensity.• Pace yourself to avoid injury or burnout.
