ch2: concepts of energy balance Flashcards
what is energy out
exercise
mvt
basal metabolic rate
digestion
estimating energy intake methods
- 24h recall
- food frequency questionnaires
- food diary
- self-reported food intake
errors of self-reported food intake
- accurate recordings
- portion sizes estimated correctly
- underestimated
biase on journal day - error in data
% of resting metabolism that accounts for a sedentary persons daily energy expenditure
70%
% of thermic effect of food (energy)
10%
% physical activity energy expenditure
20%
which component of energy expenditure is most readily influenced
food or PA
components of energy expenditure
- resting metabolism
- thermic effects
- physical activity
factors affecting resting metabolic rate
- gender
- genetics
- age
- body size
- thyroid hormone
- starvation
- amount of fat-free tissue
- exercise
- env temp
- ascending to high altitude
- caffeine intake
factors affecting resting metabolic rate
influenced not under voluntary control
gender
genetics
age
body size (height)
thyroid hormones
factors affecting resting metabolic rate
substantial influence under some voluntary control
starvation
amount of fat-free tissue
factors affecting resting metabolic rate
subtle or temporary influence, under voluntary control
exercise
env temp
ascending to high altitude
caffeine intake
energy equations
are they given lol fuck learning this
activity factors: sedentary
1.2
(little or no exercise)
activity factors: lightly active
1.375
(1-3days/week)
