A recent paper (Billat et al., 1994a) has shown the reproducibility but also the great variability between subelite long-distance runners in their time to exhaustion at the velocity which elicits VO2max, called the maximal aerobic speed (MAS). The present study delved further into the reasons for this large difference between runners having the same VO2max. The question addressed was whether the exercise-induced hypoxemia (EIH) was more important for athletes having the longest time to exhaustion at 90 (Tlim 90), 100 (Tlim 100), or 105% (Tlim 105) of MAS. The study was conducted on 16 elite male runners. EIH was observed, that is, arterial oxyhemoglobin saturation and arterial partial pressure of oxygen dropped significantly after all the Tlim tests. However, EIH was only correlated with Tlim 90 (r = -0.757; -0.531, respectively).
最近的一篇论文（比拉特等人，1994年a）表明，在次精英长跑运动员中，以引发最大摄氧量的速度（称为最大有氧速度，MAS）进行运动至力竭的时间具有可重复性，但也存在很大差异。本研究进一步探究了最大摄氧量相同的跑步者之间存在如此大差异的原因。所探讨的问题是，对于在MAS的90%（Tlim 90）、100%（Tlim 100）或105%（Tlim 105）时力竭时间最长的运动员，运动诱发低氧血症（EIH）是否更为重要。该研究对16名精英男性跑步者进行。观察到了EIH，即在所有Tlim测试后，动脉血氧血红蛋白饱和度和动脉血氧分压显著下降。然而，EIH仅与Tlim 90相关（r分别为-0.757；-0.531）。
