为了评估有氧过程对跑步速度(v)的相对贡献，我们根据1987年田径赛季中800m， 1500m， 3000m和5000m的中距离成绩选择了27名男运动员。他们的成绩所对应的平均跑动速度（.hivin.v）要优于法国最优秀的.hivin的90%，才能入选研究对象。这个季节的V。最大耗氧量（.ovrhdot. vo2max）和跑步能量消耗(C)在田径赛季前2个月内测量，再加上休息时的耗氧量（.ovrhdot. vo2max），我们可以计算出在有氧条件下可以持续的最大v: vamax = (.ovrhdot. vo2max)。的最大摄氧量-.ovrhdot。VO2rest)同学们。颈- 1。跑步机的运行v对应于血乳酸浓度为4毫摩尔。L-1 （v1a4）也被计算。全组C与身高显著相关（r = -0.43; P < 0.03）。C和。ovrhdot都不是。最大摄氧量（在本例中，3000米运动员除外）与.ovrhdot.v相关。另一方面，vamax与.ovrhdot呈显著相关。V在超过800米的距离上。这些.ovrhdot。V也与v1a4相关。然而v1a4出现在vamax的87.5% SD 3.3%，这一关系被解释为vamax与.ovrhdot.v之间的相关性表达。热应力的计算为分析其性能提供了一种有用的手段。在研究的成就水平上，。V持续超过3000 m对应于vamax。v/vamax作为赛事持续时间的函数关系的形状提出了一个问题，即在中长跑比赛中，C作为v的函数可能会发生变化。
In order to assess the relative contribution of aerobic processes to running velocity (v), 27 male athletes were selected on the basis of their middle-distance performances over 800, 1500, 3000 or 5000 m, during the 1987 track season. To be selected for study, the average running velocity (.hivin.v) corresponding to their performances had to be superior to 90% of the best French .hivin.v of the season. Maximum O2 consumption (.ovrhdot.VO2max) and energy cost of running (C) had been measured within the 2 months preceding the track season, which, together with oxygen consumption at rest (.ovrhdot.VO2max) allowed us to calculate the maximal v that could be sustained under aerobic conditions: vamax = (.ovrhdot.VO2max -.ovrhdot.VO2rest) .times. C-1. The treadmill running v corresponding to a blood lactate of 4 mmol .cntdot. l-1 (v1a4), was also calculated. In the whole group, C was significantly related to height (r = -0.43; P < 0.03). Neither C nor .ovrhdot.VO2max (with, in this case, the exception of the 3000 m athletes) were correlated to .ovrhdot.v. On the other hand, vamax was significantly correlated to .ovrhdot.v over distances longer than 800 m. These .ovrhdot.v were also correlated to v1a4. However v1a4 occurred at 87.5% SD 3.3% of vamax, this relationship was interpreted as being an expression of the correlation between vamax and .ovrhdot.v. Calculation of vamax provided a useful means of analysing the performances. At the level of achievement studied, .ovrhdot.v sustained over 3000 m corresponded to vamax. The shape of the relationship of v/vamax as a function of the duration of the event raised the question of a possible change in C as a function of v during middle-distance running competitions.
