Four testing protocols were completed by each of 10 runners using a common speed for protocols 1 and 2 (P1 and P2), each runner's training pace for protocol 3 (P3) and a speed selected manually by the runner for protocol 4 (P4). Stages were increased by 2.5% grade every 2 min for each protocol except for P1, which had 1 min stages. There were no significant differences in maximum oxygen uptake (VO2 max) between protocols (P1, 65.0 +/- 5.6 ml.kg-1 min-1; P2, 64.5 +/- 5.3 ml.kg-1 min-1; P3, 66.2 +/- 3.9 ml.kg-1 min-1; P4, 64.7 +/- 5.8 ml.kg-1 min-1). Treadmill time was significantly less for P1 than for the other protocols. The rate of perceived exertion obtained at maximal exercise during P1 was less than that obtained during the other three protocols. Heart rate was significantly lower (P less than 0.05) at any level of submaximal VO2 during P3 than during the other protocols. We recommend a testing protocol using speeds approximating the runner's training pace and 1 min stages. This may result in lower perception of difficulty and HR throughout the test and shorter testing times.
10名跑步者每人完成了四种测试方案。方案1和方案2（P1和P2）采用共同速度，方案3（P3）采用每名跑步者的训练配速，方案4（P4）采用跑步者手动选择的速度。除P1的阶段为1分钟外，每个方案每隔2分钟坡度增加2.5%。各方案之间的最大摄氧量（VO2 max）无显著差异（P1，65.0±5.6毫升·千克⁻¹·分钟⁻¹；P2，64.5±5.3毫升·千克⁻¹·分钟⁻¹；P3，66.2±3.9毫升·千克⁻¹·分钟⁻¹；P4，64.7±5.8毫升·千克⁻¹·分钟⁻¹）。P1的跑步机测试时间显著短于其他方案。P1在最大运动时的主观用力程度低于其他三个方案。在任何亚最大VO2水平下，P3期间的心率均显著低于其他方案（P<0.05）。我们推荐一种测试方案，采用接近跑步者训练配速的速度和1分钟的阶段。这可能会使整个测试过程中的难度感知和心率降低，并缩短测试时间。
