The purpose of this study was to examine the relationship between total estimated work, bar load and total oxygen consumption (TVO2) during the deadlift exercise. Forty-two observations of TVO2 during a wide range of deadlifting bouts were made on a heterogeneous sample of 10 males and 14 females. TVO2 was measured by standard open-circuit spirometry. An R of 0.912 for work and TVO2 indicated that total estimated work during deadlifting can be used to predict oxygen cost accurately. The calculated regression equation was TVO2 (litres of O2) = 2.63 + 0.80 work (kJ) with a S.E.E. of 1.50 litres O2. An R of 0.909 for bar load and TVO2 indicated essentially the same predictability using bar load as the independent variable. The calculated regression equation was TVO2 (litres O2) = 2.88 + 0.005 bar load (kg) with a S.E.E. of 1.5 litres O2. Care should be taken when converting oxygen cost to energy expenditure values using non-protein R equivalents, since underestimations are likely, due to the heavy glycolytic involvement.
本研究的目的是检验硬拉运动中总估计功、杠铃负荷与总耗氧量（TVO2）之间的关系。对10名男性和14名女性的异质样本在广泛的硬拉回合中进行了42次TVO2观测。TVO2通过标准开路肺量计测量。功与TVO2的相关系数R为0.912，表明硬拉过程中的总估计功可用于准确预测氧气消耗成本。计算出的回归方程为TVO2（升O2）=2.63+0.80×功（kJ），标准误差估计值（S.E.E.）为1.50升O2。杠铃负荷与TVO2的相关系数R为0.909，表明以杠铃负荷作为自变量时具有基本相同的可预测性。计算出的回归方程为TVO2（升O2）=2.88+0.005×杠铃负荷（kg），标准误差估计值为1.5升O2。当使用非蛋白质R当量将氧气消耗成本转换为能量消耗值时应谨慎，因为由于糖酵解的大量参与，可能会出现低估。
