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 Energy Right food Enough Energy Maintains correct weight 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… 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. High-protein Diets 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.
