TY - JOUR AU - Scott, Christopher PY - 2005 DA - 2005/12/01 TI - Misconceptions about Aerobic and Anaerobic Energy Expenditure JO - Journal of the International Society of Sports Nutrition SP - 32 VL - 2 IS - 2 AB - The measurement of gas exchange has played an invaluable role in metabolic interpretation. The uptake of 1 liter of oxygen is often converted into an energy expenditure estimate of 21.1 kilojoules (e.g., 1 L O2 = 21.1 kJ or ~5 kcal). This article demonstrates both the importance of such a conversion and the potential for misinterpretation. Oxygen uptake during heavy and severe exercise will also be discussed.
