CARDIORESPIRATORY
ENDURANCE
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.
 Prolonged exercise


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.


Short-term exercise
Benefits of Aerobic Exercise



Higher maximum oxygen
 Increase in bone density
uptake
(weight bearing bones)
Increase in oxygen-carrying  Decreased recovery time
capacity of the blood.
 Decreased blood
Decrease in resting heart
pressure & blood lipids.
rate
Increase cardiac
output & stroke
volume.
Lower heart rate at given
workloads.
Reduced risk of heart
disease, type II diabetes
