本研究的目的是检查增量运动测试期间一系列疲劳阶段对感知劳累 (RPE) 评级和估计时间限制 (ETL) 的影响。二十七名骑自行车的人进行了连续增量测试和随机负载的间断测试。使用线性混合模型来比较两次运动测试期间获得的 RPE、ETL、呼吸气体、心率和血液数据。 RPE 和 ETL 在测试之间没有显着差异。在最后一次增量测试工作负载期间，通气量、呼吸频率、心率和血乳酸浓度显着升高。总之，尽管增量运动测试产生的心肺和肌肉工作负荷比随机运动测试期间观察到的更高，很可能是由于更大的疲劳过程，但这些更高的工作负荷并没有影响知觉反应。
The purpose of this study was to examine the effects of a succession of fatiguing stages, on ratings of perceived exertion (RPE) and estimated time limits (ETL) during an incremental exercise test. Twenty-seven cyclists performed a continuous incremental test and a discontinuous test with randomized workloads. A linear mixed model was used to compare the RPE, ETL, respiratory gas, heart rate, and blood data obtained during the two exercise tests. RPE and ETL were not significantly different between the tests. Ventilation, breathing frequency, heart rate, and blood lactate concentration were significantly higher during the last incremental test workloads. In conclusion, although the incremental exercise test generated higher cardiorespiratory and muscular workloads than observed during the randomized exercise test, most likely due to a greater fatiguing process, these higher workloads did not influence the perceptual response.
