The Borg Scale is a method to measure a personâs perceived exertion rate. Developed by Stockholm University professor Gunnar Borg during the 1980s, the scale does not require any equipment, but asks participants who engage in physical activity to assess his or her perceived rate of exertion from light to strenuous. The scale measures exertion in a range between six and 20.
How Borg RPE Reflects Heart Rate. You may wonder why the Borg RPE scale starts at 6 and goes to 20. This is because it is designed to give you a fairly good estimate of your actual heart rate during activity. To do this, multiply your RPE by 10 to get an estimated heart rate. For example, if your RPE is 12, then 12 x 10 = 120 beats per minute. This scale was designed for the average healthy adult.
