摘要

Purpose: To examine whether a 3-min all-out test can be used to obtain accurate values for the maximal lactate steady state (nu(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 nu(END) (mean velocity during the last 30 s of the 3-min all-out test) itself and nu(END) +0.2, +0.1, -0.1, -0.2, -0.3, or -0.4 m/s. Results: nu(MLSS) and nu(END) were correlated (r = .69, P = .004), although nu(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 nu(MLSS) or VO2peak for well-trained runners.
