Abstract
Introduction. - The new best female performance on marathon corresponds to a velocity equal to 17.98 km · h-1. Methods. - To sustain this velocity for 2 h 20 min, an oxygen consumption equal to 54 mL · min-1 · kg-1 is required (with the hypothesis of a very economical stride with a gross oxygen cost equal to 180 mL · min-1 · km-1). To be able to maintain this oxygen consumption for more than 2 hours, the fractional utilisation of maximal oxygen consumption (85% of VO(2max) over the marathon) must be below the onset of blood lactate accumulation. Conclusion. - To be able to run the marathon at 18 km · h-1, a maximal oxygen consumption equal to 1/0.85 x 54 = 74.7 mL · min-1 · kg-1, a onset of blood lactate accumulation at 90% of VO(2max) and a gross running oxygen cost equal to 180 mL · min-1 · km-1 are required. These data have already been observed for women.
