When referring to the Borg rating system, what does the number 6 represent?

In the Borg rating of perceived exertion (RPE) scale, which ranges from 6 to 20, the number 6 corresponds to "no exertion at all." This scale allows individuals to rate their level of effort during physical activity based on their perception of exertion. The selection of 6 represents a state where an individual feels no physical strain or effort in their activities, making it clear that they are not engaged in any form of exercise or exertion.

The other choices represent different levels of exertion according to the Borg scale. For instance, "very light" generally refers to a level of effort that is noticeably above resting but still quite minimal. "Somewhat hard" indicates a moderate level of effort that is challenging yet manageable, while "maximal exertion" reflects the highest level of effort, where the individual is pushing themselves to their limits. Understanding this spectrum helps users of the Borg scale assess and communicate their physical sensations accurately during exercise.
