Question

Quizplus · Accepted Answer

Indirect calorimetry is the most practical because it is portable and less expensive compared to direct calorimetry. Direct calorimetry involves the measurement of heat produced directly from a sample, which requires a large and expensive calorimeter. On the other hand, indirect calorimetry estimates heat production by measuring oxygen consumption (VO2) and carbon dioxide production (VCO2) through respiration, which can be easily done using handheld devices or metabolic carts. Therefore, indirect calorimetry is the preferred choice for practical applications such as clinical settings or sports performance analysis.
