Chapter 7 Textbook
Course Packet page 25
Cardiovascular Fitness

Ability of the heart, lungs, and blood
vessels to function efficiently when a
person exercises the body
What is the Cardiovascular
System made up of?

Heart, blood, and blood vessels
What is the Respiratory
System made up of?

Lungs and air passages
What are the jobs of the
heart, arteries, and veins?
Heart: pumps blood throughout the body
 Arteries: carry blood away from the heart
to the body
 Veins: carry blood back to the heart

Resting Heart Rate
&
Active Heart Rate

Resting heart rate: 80 beats per minute

Active heart rate: 140-220 beats per
minute
Life Choices that hinder or
support the cardiovascular
system and/or respiratory
system
Activity level
 Diet and Nutrition
 Smoking, drinking, drugs
 Genetics, heredity

FIT Formula
Aerobic vs. Anaerobic
Activity
Aerobic activity
 Activity steady enough to
allow the heart to supply
all the oxygen your
muscles need
 Example: jog
Anaerobic activity
 Activity so intense that
your body cannot supply
adequate oxygen to
sustain it for long periods
of time

Example: sprint
Skill-related Fitness

Parts of fitness that help a person perform
well in sports
– SKILLS
– (agility, balance, coordination, power, reaction
time, speed)
Skill-related Anaerobic Activities

(Sprinting bursts in a sport)
Running a route in football
 bursts of speed in soccer or basketball –
for example attacking the ball in soccer,
recovering back on defense to prevent the
opponent from scoring
 Sprint in track
 Sprint the bases in baseball/softball

HEART
 The heart is an involuntary muscle
– It beats regularly without you telling it to do so
Effect of Exercise On the Heart
Ways to assess cardiovascular
fitness…
*Maximal Oxygen Uptake Test
 PACER
 Walking Test
 Step Test
 Mile Run

Thresholds of Training
Calculate YOUR Target Heart Rate
Zone

Low end (target threshold)
– [220 – your age x .65]

High end (target ceiling)
– [220 – your age x .85]
