Specific Diets
Year 10 GCSE
To begin:
• Swap the questions you created
for each other on diet.
• Have a go at answering and
remember to PEEL!
Aims:
• Know how diet links to levels of activity.
• Understand the correct and appropriate
times for eating.
• Understand special diets that particular
types of performers might need.
Key Terms:
Term
• Basal Metabolic Rate:
• Calorie:
• Glycogen
Definitions
• The minimum rate of
energy required to keep all
of the life processes of the
body maintained when at
rest.
• A unit that measures heat
or energy production in the
body.
• The form of carbohydrate
storage, which is converted
into glucose as needed by
body to meet energy
needs.
Levels of participation:
• Mo Farah
• Usain Bolt
• Will their diets be different?
• Why?
• Explain their different needs to a partner.
Create revision aid…
• Using the equipment on tables, create a summary of the
information on page 52.
• You have 7 minutes!
My revision aid would be:
• Eating food
• Right food
weight
Energy
Enough Energy
Maintains correct
• Active
BMR affected, so need to balance what your
body has taken in with the amounts being used up.
• Number of calories need to balance your activity levels:
When to eat…
• On whiteboards, what have you been told?
• Before activity: do not eat too close to
performing. Wait about 2 hours after eating.
• During activity: generally you shouldn’t eat
during activity, but something light and in small
quantities would be ok (e.g. banana)
• Liquids need to be taken before, during and after
to avoid………………. Don’t take too much as it can
cause discomfort.
Specific Diets…
High-protein Diets
Carbohydrate Loading
•
•

•
•
Endurance athletes.
E.g. Marathon runners.
Eat lots of starch rich food.
E.g. pasta.
During week building up to
event.
• Increases amount of
glycogen in muscles.
• Helps delay tiredness.
• Improves performance in
end stages of performance,
due to slow release of
energy.

•
•
Power athletes.
E.g. Body builders (sprinters)
Eat lots of protein rich food.
E.g. meat, fish, eggs.
Helps to build and repair
muscle.
BUT extra protein doesn’t
build muscle in itself.
The training is the key.
High protein foods can be
difficult to digest.
Shouldn’t be eaten just
before or during
performance.
Mark these answers:
• What is basal
metabolic rate and
how is it affected when
you exercise?
• (2 marks)
• Basal metabolic rate is
the minimum rate of
energy needed to keep
the body maintained
when at rest. When
you exercise your basal
metabolic rate is
affected and you must
balance the
requirements your
body has taken in, with
the amounts that are
being used up.
• What advise would
you give someone
about eating before
activity?
• (2 marks)
• You should eat lots of
food before you
exercise to give you
lots of energy.
• Explain the type of
diet that a power
athlete should eat
and reasons for this.
• (3 marks)
• A power athletes
should eat a diet high
in protein content
such as pasta. They
should do this
because it will help
them to build and
repair muscles
damaged during
performances.
