17
Q

What are triglycerides?

A

Fats

18
Q

What are fats?

A

Triglycerides which provide the body with fatty acids for energy production

19
Q

What is the role of fats?

A

Insulate nerves, form cell membranes and cushion organs

Provide an energy store which can be broken down for aerobic energy production

20
Q

What are unsaturated fats?

A

Fat molecule that is liquid and room temperature e.g. sunflower, olive and fish oils. These can help lower cholesterol

21
Q

Is unsaturated fats good or bad?

A

Good

22
Q

What are saturated fats?

A

Fat molecule that is solid at room temperature e.g. bacon, butter. Excessive amounts can lead to heart attacks

23
Q

Are saturated fats good or bad?

A

Bad

24
Q

How do saturated fats effect performance?

A

Limit intake to reduce the risk of cardiovascular disease

25
Q

How do unsaturated fats effect performance?

A

Boosts oxygen delivery, so improves endurance recovery and reduce joint inflammation

26
Q

What are vitamins and minerals?

A

Organic and inorganic nutrients essential for healthy bodily functions

27
Q

Give 5 examples of vitamins and minerals:

A
  1. calcium
  2. iron
  3. phosphorus
  4. vitamin d
  5. vitamin c
28
Q

What is fibre essential for?

A

The function of large intestines

29
Q

Where s fibre found?

A

cereal, bread, lentils, fruit and veg

30
Q

For fibre to work properly, what do you need?

A

Adequate amount of water

31
Q

How much of the body’s weight is water?

A

Two-thirds

32
Q

What can dehydration result in?

A

Decreased plasma volume, decreased stroke volume and increase temperature and heart rate

33
Q

What are the 7 components of a balanced diet?

A 
carbs
protein
fats
vitamins and mineral
fibre
water
34
Q

What is muscle loss known as?

A

atrophy

35
Q

What is energy expenditure?

A

The sum of your metabolic rate, thermic effect of food and the energy expended during physical activity

36
Q

What is basal metabolic rate (BMR)?

A

the minimum amount of energy needed to sustain essential physiological functions at rest

37
Q

What is thermic effect of food (TEF)?

A

The energy required to eat, digest, absorb and use food taken in

38
Q

What is the equation for energy expenditure?

A

Energy expenditure = BMR + TEF = physical activity energy expenditure

39
Q

What is energy intake?

A

Measured in calories or joules, it is the total amount of energy from consumed food or drinks

40
Q

What is energy balance?

A

the relationship between energy intake and energy expenditure
