This study's aim was to investigate the test-retest reliability of the 3-min all-out running test (3MRT) in hot environments. Twelve male sprinters (age 21.2 ± 1.8 years; height 1.78 ± 0.01 m; weight 71.0 ± 1.6 kg; [Formula: see text] 55.0 ± 1.0 mL kg min) performed an incremental exercise test in a laboratory, during which the first and second ventilatory thresholds (VT and VT) and [Formula: see text] were determined. In addition, they performed two 3MRTs on an outdoor track in a hot environment, during which the critical velocity (CV) and anaerobic capacity (D') were estimated. Significant reproducibility was found in CV and D' (ICC = 0.74 and 0.61, P < 0.05). The average CV in 3MRTs (3.09 ± 0.13 m s) correlated significantly with VT (3.13 ± 0.07 m s, P < 0.05). The 3MRT is a reliable tool for measuring CV and D', while CV from 3MRT in a hot environment was identical to VT.
本研究旨在调查热环境下3分钟全力跑测试（3MRT）的重测信度。12名男性短跑运动员（年龄21.2±1.8岁；身高1.78±0.01米；体重71.0±1.6千克；[公式：见原文]55.0±1.0毫升·千克·分钟）在实验室进行了递增运动测试，期间测定了第一和第二通气阈值（VT1和VT2）以及[公式：见原文]。此外，他们在热环境下的室外跑道上进行了两次3MRT测试，期间估算了临界速度（CV）和无氧能力（D'）。发现CV和D'具有显著的可重复性（组内相关系数ICC=0.74和0.61，P<0.05）。3MRT测试中的平均CV（3.09±0.13米/秒）与VT1（3.13±0.07米/秒）显著相关（P<0.05）。3MRT是测量CV和D'的可靠工具，而热环境下3MRT的CV与VT1相同。
