What is the CR-10 scale of exertion used for?

The CR-10 scale, also known as the Borg Rating of Perceived Exertion (RPE) scale, is specifically designed to assess an individual's perceived level of exertion during physical activity. Participants use this scale to provide feedback on how hard they feel they are working, taking into consideration factors such as heart rate, breathing, and fatigue. The scale ranges from 0 (no exertion) to 10 (extremely hard exertion), allowing individuals to gauge their own intensity levels during exercise.

This self-assessment tool is crucial in exercise programming because it helps trainers and exercise physiologists tailor workouts to an individual’s fitness level and tolerance, promoting safe and effective training. It is particularly useful when objective measures such as heart rate or blood pressure might not be readily available or suitable for all populations. The CR-10 scale fosters greater awareness of personal exertion, encouraging clients to listen to their bodies and adjust their exercise intensity accordingly.
