Question	Correct Answer	Explanation
1	B	RMR measures the amount of energy required to maintain essential physiological functions while at rest.
2	C	Indirect calorimetry is the gold standard for measuring resting metabolic rate because it directly measures oxygen consumption (and CO₂ production when available).
3	C	VO₂ Master uses a modified Weir Equation to convert oxygen consumption into energy expenditure (kcal/day).
4	C	Resting Metabolic Rate typically accounts for the largest proportion (approximately 60–75%) of Total Daily Energy Expenditure.
5	B	Lean body mass (fat-free mass) is the strongest determinant of resting metabolic rate.
6	C	Fat-free mass explains most of the variation in RMR between individuals, although organs contribute the greatest metabolic activity per kilogram.
7	C	Caffeine can temporarily increase metabolic rate and should be avoided before testing.
8	B	Standardization reduces measurement variability, allowing meaningful comparisons between repeated tests.
9	B	The Fowler position promotes relaxed breathing, minimizes unnecessary muscle activity, and improves comfort during testing.
10	C	Clients should ideally rest for 5–10 minutes before data collection to allow VO₂ and heart rate to stabilize.
11	C	Talking and movement increase oxygen consumption and heart rate, reducing test validity.
12	B	Stable VO₂, heart rate, and ventilation indicate the client achieved a physiological steady state.
13	B	A sudden increase in heart rate usually indicates movement, talking, coughing, or increased sympathetic nervous system activity.
14	C	EPOC is the elevated oxygen consumption that occurs after exercise while the body returns to homeostasis.
15	B	Adaptive thermogenesis is the reduction in resting metabolic rate that can occur during prolonged calorie restriction or weight loss.
16	B	Higher HRV generally reflects greater parasympathetic activity and improved physiological adaptability.
17	B	Respiratory frequency helps assess how relaxed the client remained during the measurement and can assist with evaluating test quality.
18	B	Before interpreting an unusually high RMR, first investigate client preparation, equipment setup, calibration, and testing conditions.
19	C	Body recomposition refers to increasing lean mass while reducing fat mass, often with little change in total body weight.
20	B	RMR should always be interpreted alongside heart rate, HRV, respiratory frequency, graphical trends, and the client’s preparation and testing conditions.
