The Rating of Perceived Exertion (RPE) is an important measure of exercise intensity, which is useful both as a primary and adjunctive method of exercise prescription. However, there are multiple variants of the Borg RPE scale, primarily the BORG-RPE (6-20) and the BORG-CR (0-10) scales. There are inadequate data available to address the comparability and interchangeability of these two widely used variation of the scales. Well-trained non-athletes performed two increment cycle tests, with each scale used in a random sequence. They also performed interval sessions at three intensities (50, 75 and 85% of peak power output) with each scale used in a random sequence. There were very large correlations during incremental exercise between conventional physiologic measures (% heart rate reserve (r = 0.89 & r = 0.87; and %VO2reserve (r = 0.88 & r = 0.90)) and RPE measured with either BORG-RPE or BORG-CR10, respectively. This pattern was also evident during interval exercise (% heart rate reserve (r = 0.85 & r = 0.84, and blood lactate concentration (r = 0.74 & r = 0.78)) and RPE measured with either BORG-RPE or BORG-CR10, respectively. The relationship between RPE measured with BORG-RPE and BORG-CR10 was large and best described by a non-linear relationship for both incremental (R2=0.89) and interval (R2=0.89) exercise. The incremental and interval curves were virtually overlapping. We conclude that the two most popular version of the RPE scale, BORG-RPE and BORG-CR10 are both highly related to conventional physiologic measures and very strongly related to each other, with an easily described conversion.

在增量运动和间歇运动中感觉到的运动量表的等级比较

知觉运动量（RPE）是锻炼强度的重要指标，可作为锻炼处方的主要方法和辅助方法。但是，Borg RPE秤有多种变体，主要是BORG-RPE（6-20）和BORG-CR（0-10）秤。没有足够的数据来解决这两个广泛使用的量表变化的可比性和互换性。受过良好训练的非运动员进行了两个增量循环测试，每种量表均以随机顺序使用。他们还以三种强度（峰值功率输出的50％，75％和85％）进行间隔训练，每种刻度都以随机顺序使用。在增量运动过程中，传统的生理指标（％心率储备（r = 0.89＆r = 0.87；％VO2储备（r = 0.88＆r = 0.90））和分别用BORG-RPE或BORG-CR10测量的RPE。这种模式在间歇运动期间也很明显（分别使用BORG-RPE或BORG-CR10测量的心率储备百分比（r = 0.85＆r = 0.84，血乳酸浓度（r = 0.74＆r = 0.78））和RPE。 。用BORG-RPE和BORG-CR10测量的RPE之间的关系很大，最好用增量运动（R2 = 0.89）和间隔运动（R2 = 0.89）的非线性关系来描述，增量和间隔曲线实际上是重叠的我们得出结论，RPE量表的两个最受欢迎的版本是BORG-RPE和BORG-CR10都与常规生理指标高度相关，并且彼此之间非常相关，并具有易于描述的转换。精力，心率，
