Watch the video, decide
whether the movement
is aerobic or anaerobic
movements
Aerobic exercise
•
Aerobic exercise need a
sufficient supply of
oxygen
to the tissues.
•
Work for a long time
•
Moderate – hard work
•
Periods of more then
60s
Anaerobic exercise
•
No oxygen
is used in its
initial release, energy is
produced from the
supplies already in the
body.
•
Maximum
bursts of
energy
•
Time it takes to do is very
short
Extension task
Explain how a
games player
would use
both aerobic
and anaerobic
systems

Glucose + oxygen -----Energy + CO2 + water
Glucose -----Energy + lactic acid
Aerobic Respiration -
The muscles and liver store glucose (main source of energy from food)
Anaerobic Respiration -
Is toxic!,
causes muscle ache,
cramps eventually stopping
them from working!
Fats
:
Fuel source for aerobic activity
The muscles and liver store glucose (main source of energy from food)
Carbohydrates
:
Fuel source for anaerobic and

Oxygen debt is….
Oxygen debt is…
The amount of oxygen needed at the end of a physical activity to break down lactic
acid. Often after a 400m race lactic acid builds up as the oxygen stores have run out.
Oxygen is repaid through deep gasping breaths at the end of exercise.
Glucose -----Energy +
lactic acid

Respiratory
Increased
breathing rate
Oxygen debt
(take on enough oxygen until
it is paid
off
)
Increased tidal
volume
Muscular
Lactic acid build up (during
anaerobic exercise) –
known as
lactate
accumulation
Muscle fatigue
(because of the
build up of lactic
acid)
Oxygen debt as
a result of
anaerobic
exercise
Cardiovascular
Increase
heart rate
Increase in
stroke volume
Increase
cardiac output
Increase in blood
pressure (diastolic
& systolic)

on the content on the left (all
4 bullet points)
“If you do what you’ve always done…you get what you’ve always got!”
The content discusses the differences between aerobic and anaerobic exercise, detailing how each system utilizes oxygen or stored energy for energy production. It explores the role of gaseous exchange in energy systems and relates it to the respiratory system's function. Additionally, it covers the importance of oxygen debt and how the cardiovascular and respiratory systems collaborate to support physical activities.
