respirometric
Respirometric refers to respirometry, the measurement of respiration rates by monitoring the exchange of gases, typically oxygen and carbon dioxide, to quantify metabolic activity. In humans and other organisms, respirometry yields variables such as oxygen uptake (VO2), carbon dioxide production (VCO2), and the respiratory quotient (RQ). When used with energy expenditure calculations, VO2 and VCO2 can be converted to caloric rate using established equations.
Respirometry can be open-circuit (flow-through) or closed-circuit. Open-circuit systems draw ambient air through a mouthpiece or
Applications span physiology, medicine, and sports science, including assessment of resting metabolic rate, exercise metabolism, and
Limitations include sensitivity to environmental conditions, the need for steady-state measurements for some metrics, and the
