Diet and Nutrition is examined in Paper 2, Factors affecting optimal performance in physical activity and sport.
It covers carbohydrate, fibre and fats for exercise, protein, vitamins and minerals, hydration before, during and after exercise and creatine, sodium bicarbonate, caffeine and glycogen loading.
Sample questions from Diet and Nutrition
Answer each one closed book first, then open the answer.
-
Carbohydrate, fibre and fats for exercise
Define dietary fibre.
Show the answer
Dietary fibre is the indigestible part of plant foods such as wholegrains, fruit, vegetables and pulses. Fibre passes through the gut largely undigested. -
Carbohydrate, fibre and fats for exercise
What is saturated fat, and which foods are rich in it?
Show the answer
Saturated fat comes mainly from animal sources and is usually solid at room temperature. Butter, cheese, cream and fatty meat are rich sources. -
Protein, vitamins and minerals
How might a lack of vitamin C affect an injured performer?
Show the answer
Vitamin C is needed to make collagen, the protein in tendons, ligaments and scar tissue. A deficiency would slow the healing of damaged tissue. -
Protein, vitamins and minerals
What can a high sodium intake in the everyday diet lead to?
Show the answer
A high sodium intake can raise blood pressure. High blood pressure increases the risk of heart disease and stroke. -
Hydration before, during and after exercise
A footballer loses 1.2 kg of body mass during a match. Using a guideline of 1.5 litres of fluid per kilogram lost, how much should be drunk afterwards?
Show the answer
The footballer should drink about 1.8 litres of fluid. Fluid needed = 1.2 kg × 1.5 L per kg = 1.8 L. -
Hydration before, during and after exercise
When is a hypotonic drink most useful?
Show the answer
A hypotonic drink is more dilute than body fluids and is absorbed fastest. A hypotonic drink suits performers who need fluid more than fuel. -
Creatine, sodium bicarbonate, caffeine and glycogen loading
Which events are most likely to benefit from sodium bicarbonate?
Show the answer
Events lasting roughly one to seven minutes that rely heavily on anaerobic glycolysis benefit most. Examples include the 800 m, the 1,500 m and 2,000 m rowing. -
Creatine, sodium bicarbonate, caffeine and glycogen loading
Why does the depletion phase increase the amount of glycogen stored afterwards?
Show the answer
Glycogen depletion stimulates the activity of the enzyme glycogen synthase. The muscles then store more glycogen than normal when carbohydrate returns, which is called supercompensation.
The 4 subtopics
One subtopic is one session. Work down the list.
| Subtopic | What it covers | Questions |
|---|---|---|
| Carbohydrate, fibre and fats for exercise | Carbohydrate and glycogen stores, simple and complex carbohydrates, fibre, fat as a fuel, saturated and trans fats, and LDL and HDL cholesterol. | 15 |
| Protein, vitamins and minerals | Protein for repair and strength athletes, vitamins C, D, B-12 and the B-complex, and sodium, iron and calcium for performers. | 16 |
| Hydration before, during and after exercise | Dehydration and thermoregulation, fluid loss and worked calculations, hydrating before, during and after exercise, isotonic, hypotonic and hypertonic drinks, and hyponatraemia. | 15 |
| Creatine, sodium bicarbonate, caffeine and glycogen loading | Creatine, sodium bicarbonate and caffeine with their benefits and side effects, traditional and modern glycogen loading, and the pre-competition meal. | 17 |
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.
