Rating of Perceived Exertion Scales

There are two versions of this scale. Below is shown the category-ratio version with the ratings between 0 (nothing at all) and 10 (very very hard). This is also called the Borg CR10 Scale. There is another very similar RPE scale also developed by Borg, with the .

Gunnar Borg, PhD,introduced the field of perceived exertion during the latter part of the 1950s. Since then, he has won international renown for his work in developing methods for measuring perceived exertion and pain. His method for measuring perceived exertion is the main method used in the field, and his new scale, the Borg CR10 scale, is used for measuring both perceived exertion and pain, and other subjective magnitudes.

Borg CR 10 Scale (Dyspnea assessment)

  • Borg 6-20 - the original scale as developed by Borg, with the ratings between 6-20 which can correspond to 1/10 of the exercise heart rate.
  • Borg CR10 - an updated combined category and ration scale by Borg with the ratings between 0 (nothing at all) and 10 (very very hard).
  • Rob's RPE-5 Hand Scale - a new scale with some advantages over the other scales. For this RPE Scale, the subject just holds up the fingers of their hand to indicate the intensity level - from 1 to 5.

The RPE Scale is a common method for determining exercise intensity levels. It is commonly used in some research studies for that purpose, but may also be used in training programs to describe the intensity of training sessions. The scale of perceived exertion is how hard you feel your body is working, and so is a subjective measure.

The scale is based on the research of Borg, and is sometimes called the Borg Scale. You can download a copy of this .

The Borg CR10 Scale is more useful for statistical analysis than the Borg RPE. On the CR10 scale, twice the rating is likely to be twice as hard. While the Borg CR10 scale does not correspond with any physiological measures such as , this is not really an issue in practice. While this scale has a maximum value of 10, Borg's definition says that it is acceptable to use greater numbers if the subject so desires.
