What does the Borg rating measure?

The Borg rating scale, also known as the Rating of Perceived Exertion (RPE) scale, specifically measures the intensity of physical activity based on an individual's perception of their exertion level. It was developed by Gunnar Borg and is typically used in exercise settings to help individuals assess how hard they believe they are working during physical activity.

The scale usually ranges from 6 to 20, with lower numbers indicating minimal effort and higher numbers indicating maximal effort. This subjective measure is valuable because it allows individuals to tune into their body’s signals regarding how hard they are working, which can differ significantly from objective measures like heart rate or calories burned.

Using the Borg rating can help guide exercise intensity in a way that is personalized to an individual's fitness level and comfort, making it a practical tool in both rehabilitation and fitness coaching contexts. This is particularly important for populations that may not be familiar with other metrics of exertion or for those who may have varying physical capabilities. Hence, the Borg rating's focus on perceived exertion makes it an essential aspect of designing safe and effective exercise programs.
