摘要：The lactate minimum protocol (LM) is preceded by a maximum effort to induce hyperlactatemia. Objective: To verify the reliability of LM test with induced hyperlactatemia realized by exercise intensity individualized by the rating perceived effort (RPE). Methods: The sample was composed of 20 students, physically active (25.4 ± 4.1 years, 14.1 ± 5.0% fats) who were undertaken to two tests with identical methodology of LM. Induction of hyperlactatemia was performed by a test with four stages, lasting three minutes each, loads individualized by the PSE (levels 10, 13, 16 and 17-20 last stage until voluntary exhaustion). After eight minutes of recovery the progressive test started with initial load of 75W and 25W increments every 3 min until exhaustion. Results: The intensities of LM 1 (155.0 ± 23.8 W) and 2 (157.5 ± 27.0 W) did not differ statistically (p = 0.795) and showed good reliability (ICC = 0.79) and agreement [-2.5 W of mean difference and ± 41.8 W of bias]. Conclusion: The LM test, with loads for induction of hyperlactatemia individualized by the RPE, has shown to be reliable in physically active individuals.
