The size and complexity of which device makes them unsuitable for measuring energy expenditure for short time intervals, particularly less than 30 minutes?
A) room-size calorimeters
B) metabolic cart
C) simplified portable system
D) doubly labeled water (DLW)

Question

Quizplus · Accepted Answer

Room-size calorimeters are large and complex devices that are designed for measuring energy expenditure over long periods of time. They are not suitable for short time intervals, particularly less than 30 minutes. For short time intervals, simplified portable systems or metabolic carts are better options. DLW is a method for measuring average daily energy expenditure over a period of several days and is not designed for short-term measurements.
