Which

of the following are the three main components of total energy expenditure?

Resting

metabolic rate, diet quality, physical activity

Resting

metabolic rate, exercise, body composition

Basal

metabolic rate, sleep, emotional stress

Resting

metabolic rate, thermic effect of food, physical activity

How

does RER provide information about which fuel source is being used?

calculates the total energy intake from food and drink

reflects the ratio of carbon dioxide produced to oxygen consumed, which differs

for carbohydrate and fat oxidation

measures nitrogen excretion, which indicates protein metabolism

measures how much heat is released when foods are combusted

When
carbohydrate is stored as glycogen, approximately what proportion of the energy
obtained from that carbohydrate is used in the storage process?

About

15%

About 7%

About

25%

About

What

does a respiratory exchange ratio (RER) of 1.0 indicate?

Anaerobic

metabolism is occurring

Predominant

use of fats as fuel

Predominant

use of carbohydrate as fuel

Equal

use of carbohydrate and fat as fuel

Which

of the following is TRUE regarding skinfold measurements?

Accuracy

depends heavily on the assessor’s skill, and they provide a poor estimate of

body fat percentage

They

are an accurate method for assessing visceral fat stores

They are the best body composition measurement for athletic or lean populations

They

require advanced laboratory equipment

Approximately

what percentage of total daily energy expenditure comes from resting metabolic

rate (RMR) in most individuals?

85–95%

10–20%

60–75%

30–40%

Which

of the following factors influence body weight regulation?

Metabolism

alone

Genetics,

hormones, environment, and behaviour

Only

dietary intake and physical activity

Psychological

factors only

When

is it most appropriate to measure body composition?

Routinely

in all exercise settings

It is always appropriate

every doctor’s visit to track weight loss

Only

when it serves a clear purpose and is necessary for health or performance

What

does a bomb calorimeter measure?

Amount

of oxygen used during exercise

Heat

released during digestion of food in the body

Heat

released from the complete combustion of food

Resting

energy expenditure
