Calorimetry is:

Explanation:
Calorimetry is the measurement of energy expenditure. It can be direct, by capturing the heat the body produces in a calorimeter, or indirect, by assessing oxygen consumption (and CO2 production) to estimate how much energy is being used. This makes it the method used to quantify the body's energy output during activity. The other terms describe metabolic thresholds or maximal capacity (like lactate threshold, OBLA) or maximal oxygen uptake (VO2 max), which are about performance markers, not the measurement of energy expenditure itself.
