Repayment of oxygen debt incurred during physical effort is determined by measuring the extra oxygen used above the resting value during a recovery period of 0.5 to 1 h. Since this imposes an additional stress on the experimental subject, an attempt has been made to develop a simple, quick, and accurate method for determining oxygen debt. The method described here is based on the fact that the curve describing recovery is the resultant of two exponential curves, one fast and one slow, the former being complete in less than 3 min. We have derived a mathematical equation by means of which the total oxygen debt measurable over a 60 min period can be extrapolated from the measurements of excess oxygen consumption over the resting value at the end of 3, 6, and 9 min of the recovery period. The equation has been validated by observations on 10 young healthy subjects at sea level and at high altitude. The results show that the equation has good predictive value.
通过测量在0.5至1小时的恢复期内超过静息值所使用的额外氧气量，来确定体力活动期间产生的氧债偿还情况。由于这会给实验对象带来额外压力，因此人们一直在尝试开发一种简单、快速且准确的方法来确定氧债。此处描述的方法基于这样一个事实，即描述恢复过程的曲线是两条指数曲线的合成结果，一条快曲线和一条慢曲线，前者在不到3分钟内完成。我们推导出了一个数学方程，通过该方程，可以根据恢复期3分钟、6分钟和9分钟末超过静息值的耗氧量测量值，外推出60分钟内可测量的总氧债。该方程已通过对10名年轻健康受试者在海平面和高海拔地区的观察得到验证。结果表明该方程具有良好的预测价值。
