What does a score of 20 on the Borg scale indicate?

A score of 20 on the Borg scale indicates maximum exertion. The Borg Rating of Perceived Exertion (RPE) scale is a subjective measure that helps individuals rate the intensity of their exercise based on how hard they feel they are working. It typically ranges from 6 to 20, with lower numbers representing very light activity and higher numbers indicating increasing levels of exertion.

When a person rates their exertion as 20, they are expressing that they are at their highest possible level of effort, experiencing extreme fatigue and difficulty in performing any additional physical activity. This score is often used in exercise settings to help gauge the intensity of workouts and ensure that individuals are training at appropriate levels for their fitness goals.

Understanding this scale is vital for both participants and trainers, as it helps in monitoring exercise intensity and ensuring safety during physical activity.
