Which term describes the calculation of heat in physical changes and chemical reactions?

• A. Lactate threshold
• B. Calorimetry
• C. EPOC
• D. VO2 max

Answer: (B)

Calorimetry is the measurement of heat involved in physical changes and chemical reactions. It quantifies the energy released or absorbed as substances change state or react, typically using a calorimeter to capture the heat flow. This directly links to how much energy is produced or required in metabolic processes during exercise, combustion, or phase changes. Other terms relate to different aspects of exercise physiology: lactate threshold concerns the intensity at which lactate builds up in the blood, EPOC describes the extra oxygen used after exercise to recover, and VO2 max is the maximum rate of oxygen uptake. Calorimetry best describes the measurement of heat energy changes.
