The metabolism of an animal is
estimated by determining rates of carbon dioxide production
(VCO2) and oxygen
consumption (VO2) of individual animals, either
in a closed or an open-circuit respirometry
system. VO2 max is a measurement of the maximum
amount of oxygen an individual uses during physical
activity. It is measured as milliliters
of oxygen used in one minute per kilogram of body weight.
It relates energy production via aerobic metabolism to
oxygen consumption during the action of the ETC.
