Activity Energy Expenditure (AEE) Correct Answers Accounts
for about 15-25% of total energy expenditure; includes daily
activities, physical activity, and exercise.
Are glycogen stores limited? Correct Answers Yes
Basal Metabolic Rate (BMR) Correct Answers Metabolic rate
during resting conditions (awake, reclined, fasting 12-14 hours,
comfortable environment, low cellular activity).
Body Size (Effect on RMR) Correct Answers Most important
determinant of metabolic rate; accounts for about 80% of RMR
differences.
Can eating more protein increase protein stores? Correct
Answers No
Causes of EPOC Correct Answers Elevated body temperature,
increased cardiorespiratory function, ATP restoration, and lactic
acid removal.
Direct Calorimetry Correct Answers Measurement of heat
generated from metabolism; most accurate method of assessing
resting energy expenditure.

No definitive evidence
, Does fat oxidation increase proportionally with fat intake?
Correct Answers No
Effect of Age on RMR Correct Answers RMR declines with
increasing age due to loss of muscle mass.
Effect of Severe Weight Loss on RMR Correct Answers
Decreases RMR, especially when lean muscle mass is lost.
Excess Postexercise Oxygen Consumption (EPOC) Correct
Answers Elevated oxygen consumption after exercise used to
restore the body to pre-exercise conditions.

Timing of measurement, exercise intensity/type, training
duration, age, fitness level, and post-exercise nutrition affect
results.
Factors Affecting NEAT Correct Answers Occupation, leisure
activities, and use of labor-saving devices.
Fat-Free Mass (FFM) Correct Answers Muscle and organs with
high metabolic activity; major contributor to RMR.
