The aims of the present study were a) to compare the outcome of running exercise performed on a treadmill (laboratory) and an outdoor track (field) using an RPE production protocol and b) to study this kind of protocol used over time (3-5 wk). A group of 11 healthy male subjects participated, with ages varying from 33 to 65 yr (mean = 42.9 +/- 11.0 yr). Two test sessions consisting of both treadmill and track exercise were performed in a rotated order to control for sequential effects. All subjects exercised according to an identical protocol: two successive trials (3 min each) at RPE 11 (light exertion), followed by a RPE 13 (somewhat hard) trial (11 min) and, finally, a RPE 15 (hard) trial (5 min). Results show significantly different levels of heart rate (HR), blood lactate, and velocity at the three RPE levels. Large differences were also observed in all measured variables between field and laboratory. These differences were consistent over time. A high internal consistency, measured by test-retest reliability (alpha greater than 0.9), was obtained for both velocity and HR between the first two trials at RPE 11. In conclusion, the RPE method functioned well as a means of monitoring and regulating exercise intensity.
a）使用主观用力程度（RPE）生成方案，比较在跑步机（实验室）和室外跑道（场地）上进行跑步运动的结果；b）研究这种方案在一段时间内（3 - 5周）的使用情况。一组11名健康男性受试者参与其中，年龄从33岁到65岁不等（平均 = 42.9 ± 11.0岁）。进行了两次测试，包括跑步机和跑道运动，测试顺序交替以控制顺序效应。所有受试者均按照相同方案进行运动：在主观用力程度为11（轻度用力）时连续进行两次试验（每次3分钟），随后是主观用力程度为13（稍费力）的试验（11分钟），最后是主观用力程度为15（费力）的试验（5分钟）。结果显示，在三个主观用力程度水平下，心率（HR）、血乳酸和速度水平存在显著差异。在场地和实验室之间的所有测量变量中也观察到了很大差异。这些差异随时间保持一致。在前两次主观用力程度为11的试验中，速度和心率的重测信度（α大于0.9）表明具有较高的内部一致性。总之，主观用力程度方法作为监测和调节运动强度的手段效果良好。
