The relationship between distance and best time is roughly linear for distances between 1500 and 5000 m. The slope of this relationship has the dimension of a velocity (Vlim) which can be sustained during a long time. The individual time-distance relationships and the resulting Vlim have been studied in 32 subjects practicing different athletic activities by measuring exhaustion time for 2 to 4 constant-velocity running exercises performed to exhaustion. The velocity corresponding to 4 mmol.l-1 of blood lactate (V4 mmol) has been compared with Vlim. As maximal oxygen uptake is a major factor determining V4 mmol, Vlim and V4 mmol have also been correlated with the result of a field test which is assumed to measure maximal aerobic power (Léger-Boucher's test). This test consists in running until exhaustion at a velocity which increases every two minutes. The higher the velocity at exhaustion (Vléger) is, the higher the maximal oxygen uptake is assumed. Both Vlim and Vléger were very well correlated with V4 mmol (r greater than 0.90) and the average value of Vlim was almost equal to the average value of V4 mmol (13.89 vs 13.71 km.h-1). However, it was not possible to estimate V4 mmol accurately from the values of Vlim or Vléger because the standard errors of estimates were too large.
对于1500米至5000米的距离，距离与最佳时间之间的关系大致呈线性。这种关系的斜率具有速度（Vlim）的量纲，且该速度能够在较长时间内维持。通过测量2至4次以恒定速度跑步直至力竭的运动的力竭时间，对32名从事不同体育活动的受试者的个体时间 - 距离关系及由此得出的Vlim进行了研究。将对应于4 mmol.l-1血乳酸的速度（V4 mmol）与Vlim进行了比较。由于最大摄氧量是决定V4 mmol的主要因素，Vlim和V4 mmol还与一项被认为可测量最大有氧功率的现场测试结果（勒热 - 布歇测试）相关。该测试包括以每两分钟增加一次的速度跑步直至力竭。力竭时的速度（Vléger）越高，假定最大摄氧量越高。Vlim和Vléger与V4 mmol均具有很好的相关性（r大于0.90），且Vlim的平均值几乎等于V4 mmol的平均值（13.89对13.71 km.h-1）。然而，由于估计的标准误差过大，无法根据Vlim或Vléger的值准确估计V4 mmol。
