Purpose:

To examine whether a 3-min all-out test can be used to obtain accurate values for the maximal lactate steady state (v MLSS) and/or peak oxygen uptake (VO2peak) of well-trained runners.

Methods:

The 15 male volunteers (25 ± 5 y, 181 ± 6 cm, 76 ± 7 kg, VO2peak 69.3 ± 9.5 mL · kg−1 · min−1) performed a ramp test, a 3-min all-out test, and several submaximal 30-min runs at constant paces of v END (mean velocity during the last 30 s of the 3-min all-out test) itself and v END +0.2, +0.1, –0.1, –0.2, –0.3, or –0.4 m/s.

Results:

v MLSS and v END were correlated (r = .69, P = .004), although v MLSS was lower (mean difference: 0.26 ± 0.32 m/s, 95% CI –.44 to –.08 m/s, P = .007, effect size = 0.65). The VO2peak values derived from the ramp and 3-min all-out tests were not correlated (r = .41, P = .12), with a mean difference of 523 ± 1002 mL (95% CI –31 to 1077 mL).

Conclusion:

A 3-min all-out test does not provide a suitable measure of v MLSS or VO2peak for well-trained runners.
