Borg RPE Scale®

This is the original 6 – 20 scale for ratings of perceived exertion. It is constructed to give interval data that grows linearly with oxygen consumption and heart rate at steady state exercise (Borg, G., 1962, 1970, 1998).

Borg CR Scale® (CR10)
This is a general intensity scale that can be used for most kinds of sensations and experiences. Traditionally, however, most applications have been in sports and training, ergonomics, physical exertion, physiology, physiotherapy, etc., to measure symptoms related to perceived exertion, pain and functional capacity. In the scientific literature, the CR10 scale is sometimes given different names depending upon the area of application. Some examples are: Borg CR-10, Borg Dyspnea Scale, Angina Scale, Fatigue Scale, Anxiety Scale, Pain Scale etc. It is also used in different scoring sheets (eg., functional index). (Borg, G., 1982, 1998).

Borg CR Scale®, Borg centiMax Scale® (CR100)
A more recently developed, finely graded version based on the same principles as the CR10 Scale but with a main number range from 0 – 100. Gunnar Borg’s Range Principle and the idea of using a common reference at 100, the previously experienced maximal exertion, gives the scale “centiMax” (cMax, cM for short) as a unit for psychological measurement. Like the CR10 scale this scale can be used for most kinds of sensations and experiences but is especially valuable when more detailed comparisons are needed (Borg, G., and Borg, E., 1994; Borg, E., 2007). The scale is used in the same areas as the CR10. Some new applications, however, are putting force in golf, performance evaluation in diving, depressive symptoms, aircraft noise and hypernasality (see References).
