1. GCSE Physical Education Dietary Intake & Performance

2. Learning Objectives By the end of this lesson pupils should:
Explain the importance of the right timing for
dietary intake for best performance
Understand and explain blood flow (blood
shunting) during exercise

3. What sort of food would this athlete eat for energy?
Task
What sort of food would this athlete eat for energy?

4. Carbo-Loading The energy to run comes from food, and
more specifically carbohydrates
Carbo-Loading refers to boosting the
amount of glycogen in the body before
competition
Knowledge of the nutrients of a balanced
diet will help you understand how it works

5. Carbo-Loading Diet Plan
Eating more protein in early part of week
will help runners’ muscles to repair
Eating high levels of carbohydrates later in
the week, will increase glycogen stores in
liver and muscles
Important to take in food in the first 2 hours
after competing or training. This will restock
carbohydrates used during activity

6. Blood Flow During Exercise
When exercise begins, blood is sent to the working
muscles
Less blood is therefore available to digest food in the
gut, which can cause cramps
The flow of blood from other areas into the muscle
is known as blood shunting.
This is why an exercise session should not start until
2/3 hours after the last meal

7. Learning Objectives (Revisited)
By the end of this lesson pupils should:
Explain the importance of the right timing for
dietary intake for best performance
Understand and explain blood flow (blood
shunting) during exercise
