The Heart of the Matter


Put your hand on your heart
Hold out your hand and make a fist
Why do we wear wedding rings on our
left hand?
lub-Dub, lub-Dub. Sound familiar?
These sounds are made by the heart
valves as they open and close
Heart Facts




The heart is a strong muscle that pumps
blood throughout your body
Your heart provides the power needed
for life
An adults heart will beat about 70 times
per minute
We have 6 quarts of blood that moves
through our body 3 times every minute



Arteries are blood vessels that carry
blood away from the heart
Veins are blood vessels that carry blood
toward the heart
Even at rest, the muscles of the heart
work hard -- twice as hard as the leg
muscles of a person sprinting
Your heart and exercise



The heart changes how fast it pumps to
meet your body’s needs.
As muscles work harder, they need
more oxygen supplied by blood from the
heart.
The heart has to beat faster to keep up
with the needs of the muscles.
Problems of the heart


Heart Attack - caused by blockage of a
coronary artery.
Damage to the heart muscle can occur
if there is insufficient blood supply for
more than 20 minutes or more.
Typical Warning Signs




Chest discomfort along with pain that
runs down the left arm
Shortness of breath
Nausea
cold sweat, light headedness
Risk Factors





Family History of early heart attack
before 65 for women before 55 for men
Age (heart attack risk increases with
age)
Race
Diabetes
High blood pressure
Blood Pressure




The pressure exerted by the heart in
pumping blood away from the heart.
High blood pressure is 140/90 or higher
Systolic (top number) is the pressure in
the arteries as the heart contracts
Diastolic (bottom number) is the
pressure in the arteries as the heart
relaxes
Did you ever wonder



Why a nurse checks your pulse during a
checkup or why they check a victims
pulse?
Your pulse tells how well your heart is
working
Many factors affect pulse rate
fitness level, genetics, stress, diet
Your heart is a muscle
 If
you want it to be strong
you need to exercise it.
Did you know



Heart Disease is the #1 killer of women.
1 in 3 women dies of heart disease
Yet women make up only 25% of
participants in heart related research
studies
How to take your pulse





Never use your thumb
Begin your count with zero
locate pulse in your wrist or neck
count for 30 seconds multiple by 2
Resting rate is your pulse rate before
you get out of bed in the morning
Target Heart Rate





To get the most benefit from aerobic
exercise you need to work out in your
target heart rate zone.
220 - your age = maximum heart rate
MHR x 60% = lower range of zone
MHR x 80% = higher range of zone
You should be in this range of 60-80%
Tuesday




In your groups
one member of group will complete 3
fitness stations
Two minutes of exercise, record pulse
after exercise, 30 seconds, 60 seconds
and 90 seconds after exercise
other team members will act as timers,
recorder, and pulse taker
