Borg Rating of Perceived Exertion Scale (RPE) is a psychophysiological measurements that translates physical stimuli to a psychological construct, which is perceived exertion. Its use is simple and it represents the effort perception. Each number of the scale is associated with a heart rate or percentage of maximal oxygen consumption (VO2max), which estimates the intensity of exercise.
To validate RPE scale in patients with type 2 diabetes mellitus (DM2).
Thirty five DM2 participants with a median age of 59 years underwent an incremental exercise test in a treadmill with breath-by-breath analysis of oxygen consumption. After every three minute stage, the RPE scale was applied and correlated with oxygen consumption variables.
There was correlation coefficient of 0.91 between RPE score and VO2max. A RPE score of 11 corresponded to 52% of VO2max, a RPE score of 13 corresponded to 76% of VO2max, a RPE of 15 corresponded to 88% of VO2max and a RPE of 17 correspondent to a 100% of VO2max.
RPE Scale is valid in patients with type 2 diabetes as an estimate of the intensity of physical activity.
伯格主观用力程度分级量表（RPE）是一种心理生理学测量方法，它将身体刺激转化为一种心理结构，即主观用力程度。其使用方法简单，代表了对努力程度的感知。该量表的每个数字都与心率或最大耗氧量（VO2max）的百分比相关，可用于估计运动强度。
验证RPE量表在2型糖尿病（DM2）患者中的有效性。
35名年龄中位数为59岁的DM2参与者在跑步机上进行递增运动试验，并逐次呼吸分析耗氧量。在每三分钟的阶段后，应用RPE量表并将其与耗氧量变量进行关联。
RPE评分与VO2max之间的相关系数为0.91。RPE评分为11时对应VO2max的52%，RPE评分为13时对应VO2max的76%，RPE评分为15时对应VO2max的88%，RPE评分为17时对应VO2max的100%。
RPE量表在2型糖尿病患者中可有效用于估计体力活动强度。
