Metabolism

Question 1

Three factors affect total daily energy expenditure (TDEE)

Answer 1

1. resting metabolic rate (basal and sleeping conditions + metabolic cost of arousal)
2. thermogenic effect of food consumed
3. energy expended during physcial activity and recovery

Question 2

What is Basal Metabolic Rate (BMR)?

Answer 2

minimum level of energy to sustain vital functions in the waking state
body’s total heat production

Question 3

What is resting metabolic rate (RMR)

Answer 3

always slightly higher than BMR

Question 4

influences on RMR

Answer 4

body size
health/fitness
muscle mass
age
hormones
body temp

Question 5

Offsets the decreases in BMR and RMR with aging

Answer 5

regular physical activity

Question 6

Five other factors that affect TDEE

Answer 6

1. physical activity
2. diet-induced thermogenesis
3. calorigenic effect of food on exercise metabolism
4. climate
5. pregnancy

Question 7

physical activity’s affect on TDEE

Answer 7

stimulates resting metabolism

offsets the decrease in resting metabolism that accompanies aging
