DIFFERENT DIETS FOR DIFFERENT ATHLETES

Understand the different types of diets required for endurance and power athletes

Learning Outcomes:

A – Use knowledge learnt of different types of diets to solve exam questions

B – Identify and Explain why the different classes of food are used for the different diets

C – Identify the different classes of food that are used for different athletes diets

Do Now Task – Attempt questions on nutrition

ANSWERS

1. Name the 6 classes of food (3 marks) – Carbohydrates, Protein, Fat, Vitamins, Minerals, Fibre

2. What are the benefits of having fibre in a diet (2 marks) – Prevents constipation, reduces blood cholesterol levels, control blood glucose levels

3. Why do people involved in physical activity need to make sure they eat foods with a sufficient amount of iron and calcium (4 marks) – Iron, formation of haemoglobin helps with transport of oxygen, important for people whose sports require a lot of cardiovascular endurance. Calcium, Main mineral in bones and teeth required to keep bones strong as they are under more stress when being physically active. Nerve and muscle function. Important for muscular strength and endurance

INFORMATION

What would be the difference in the diets of a physical active and inactive person of similar BMR’s?

In general a physically active person would need a greater intake of food to cover the extra output of energy they are using by being

active. The involvement and intensity of the activity will greaten the need

to take in sufficient food.But is just eating more food enough?

Care must be taken in maintaining a balanced diet so that performers receive all the vital nutrients they need to perform well.

ENDURANCE ATHLETES

Endurance training makes a performer better at metabolising fats.Therefore fats need to be increased.

What are benefits of fats? Double the energy to carbohydrates, Carrier for fat-soluble

vitamins, used at rest or low intensity exercises – needs lots of oxygen to break it down

This means carbohydrates can be used for later on the activity.So what do we need to do to our carbohydrate intake?

Increase it to satisfy the energy demands of the performer.

POWER/STRENGTH PERFORMER

Would a power performer also need to increase their carbohydrate intake?

Yes because it is the bodies preferred source of energy and can be used at all intensities of activity.

What other class of food would need to be increased in their diet?ProteinWhy?

Because of the increase in muscle repair and growth that accompanies their training

ANY PERFORMER

Would should any elite performer also increase in their diet?Vitamins and Minerals

Why?Because athletes generally have a higher metabolism than the

average person because of their training load

TASKS

1. Complete the performer profiles with the necessary information2. Attempt exam questions.

ANSWERS

How should the diet required by a marathon runner differ from an inactive person? (3 marks)

Higher intake of food due to increased metabolism from trainingIncreased fat intake to use as energy

Increased carbohydrate intake to satisfy the energy demands of the performer
