CARDIORESPIRATORY
ENDUCANCE
HEART / LUNGS / BLOOD AND
THE BODY
Cardiorespiratory Endurance
The most important component of physical
fitness, and best indicator of overall health.
 The measure of how efficiently our bodies
work: oxygen uptake / distribution and
utilization.
 Hypokinetic diseases: diseases due to the
lack of activity.
 Hypertension, heart disease, obesity,
cancer etc..

Aerobic / Anaerobic Exercise


Aerobic Exercise
Low to moderate
intensity exercises.
 Body requires
oxygen to produce
energy (ATP).
 Walking, jogging,
swimming, cycling,
etc.

Anaerobic Exercise
High intensity
exercises.
 Exercise that doesn’t
need oxygen to
produce energy.
 2-3 minutes of high
energy bursts.
 100, 200, 400 meter
sprints, weight
lifting, etc.

Benefits of Aerobic Exercise



Higher maximum
oxygen uptake
Increase in oxygencarrying capacity of
the blood.
Decrease in resting
heart rate

Increase cardiac
output & stroke
volume.





Lower heart rate at
given workloads.
Increase number & size
of mitochondria.
Increase number of
functional capillaries.
Increased recovery time.
Decreased blood
pressure & blood lipids.
Assessing Cardio. Endurance






Determining maximal
amount of oxygen the
human body is able to
utilize in 1 minute.
1.5 mile Run Test
1.0 Mile walk test
Step Test (3 min.)
Astrand-Ryhming Test
12-Minute Swim Test
Blood Pressure/Heart Rate
Assessment




Find pulse / count 30 seconds / multiply by 2 =
resting heart rate / beats per minute – (bpm).
Bradycardia = slower heart rate than normal
(below 40 bpm).
Systolic Blood Pressure – pressure on artery
walls during heart contractions.
Diastolic Blood Pressure – pressure on arteries
during rest phase of heart contractions.
