1

Define energy intake (EI)

EI is the total calories consumed by food or drink

2

Define energy expenditure (EE)

EE is the total calories used

3

How do you work out EE

EE = BMR + physical activity + thermic effect

4

Define energy balance

Energy balance is the relationship between EI and EE

5

Define basil metabolic rate (BMR)

BMR is their lowest amount of calories needed to carry out the bodies physiological processes at rest after 8 hours sleep and 12 hours fasted

6

Define positive energy balance

A positive energy balance is where EI is more than EE and you will gain weight

7

Define negative energy balance

A negative energy balance is where EE is more than EI and so you will loose weight

8

Define what a neutral energy balance is

A neutral energy balance is where EE is the same a sEI and so you mentain weight

9

What is the range of MET’s for moderate intensity exercise

2-5 MET’s

10

What is the MET value to which over is high intensity exercise

6+ MET’s

11

How do you work out your BMR per hour

BMR per hour = ((KG x 24) x body fat range) divided by 24

12

what is MET

MET is where VO2 = 3.5ml/kg/hr

13

Define MET

MET is a physiological meausure expressing the energy expenditure during physical activities

14

Define thermic effect

Thermic effect is the energy/calories used in the process of eating, digestion good and absorbing food
