Description

Technical field [0001] The invention relates to the technical field of gas sample collection and energy metabolism analysis, in particular to a human energy metabolism detection device and method. Background technique [0002] The gas metabolism test is based on the principle of indirect calorimetry. It calculates the energy consumption of the human body according to the amount of oxygen consumption and carbon dioxide production within a certain period of time, and the composition of the three major nutrients (carbohydrates, fats and proteins) in energy consumption. The device can be used with load equipment such as treadmills and power cars to test the human body's oxygen uptake and carbon dioxide emissions under different exercise loads. The gas metabolism test provides a reference for the assessment of cardiopulmonary function, diagnosis and treatment of diseases, and scientific nutrition supply. [0003] The early gas metabolism test is relatively simple, generally using Dougl...
