➔ Understand the difference between
aerobic and anaerobic exercise
➔ Understand what EPOC is
➔ Analyse the recovery process
Aerobic Exercise
Aerobic exercise takes place in the presence of oxygen. When exercise is over a long period of time at
a moderate to low intensity, the heart can supply all the oxygen the working muscles need.
When working aerobically, energy comes from carbohydrates, which are converted into glucose and
oxygen. Carbon dioxide and water are produced as by-products. Sweat releases water and respiration
releases CO2.
Aerobic exercise is the body’s preferred way of working because lots of energy can be produced with
few harmful by-products.
Examples: marathon running
Glucose + oxygen = energy + carbon dioxide + water
Aerobic exercise
Working at a low to moderate intensity so that the body
has time to use oxygen for energy production and can
work for a long time.
Intensity
The amount of energy needed to complete an activity.
Working at a high intensity requires a large amount of
energy. Working at a low intensity requires less energy.
Anaerobic Exercise
Anaerobic exercise takes place in the absence of oxygen. When exercise is short in duration and high
in intensity, the heart and lungs cannot supply enough blood and therefore oxygen to the working
muscles.
When working anaerobically, the muscles produce a waste product called lactic acid. As lactic acid
builds up in the muscles, they become painful, fatigued and unable to continue working as efficiently.
Therefore, the body can only work anaerobically for a short period of time (approximately 60 seconds
maximum).
Examples: sprinting; Olympic weightlifting
Glucose = energy + lactic acid
Anaerobic exercise
Working for short periods of time at a high intensity
without oxygen for energy production.
Lactic acid
A mild poison and waste product of anaerobic respiration.
Activity 1: What is EPOC?
Watch the video and
answer the following
questions
•
•
•
What does EPOC
stand for?
When does it occur?
How does it affect the
body?
Extension:
Link back to your
spirometer trace
learning. Can you
sketch a spirometer
trace for Eddie Hall?
Excess Post-exercise Oxygen Consumption (EPOC)
Excess Post-exercise Oxygen
Consumption
EPOC is
sometimes
known as
oxygen debt,
but this term is
now outdated.
The amount of oxygen needed to
recover after exercise. It is
characterised by an increased
breathing rate and deeper breathing
after exercise.
EPOC occurs after anaerobic exercise.
Breathing rate is faster and deeper.
EPOC replenishes the body with Oxygen.
It enables the body to convert lactic acid into glucose, carbon dioxide and
water
