Question

Quizplus · Accepted Answer

Direct calorimetry measures heat production directly by placing an individual in a specially designed room and measuring the heat given off to determine energy expenditure. Indirect calorimetry measures energy expenditure indirectly by measuring the respiratory quotient (RQ) using oxygen consumption and carbon dioxide production, and then calculates energy expenditure using known RQ values for different nutrient types. Therefore, both direct and indirect calorimetry are valid techniques for measuring energy expenditure in humans. Sub-direct calorimetry does not exist as a recognized technique.
