Which statement about the Rating of Perceived Exertion (RPE) scale is true?

• A. It uses a 0-10 scale
• B. It uses a 1-20 scale
• C. It measures heart rate
• D. It is only used for advanced athletes

Answer: (A)

RPE is a way to quantify how hard you feel you’re working during exercise, based on your own perception. A common version uses a zero to ten scale, where zero means no effort at all and ten means maximal effort. This setup is popular because it’s quick, intuitive, and works across different activities and fitness levels without any equipment. You gauge intensity by how breathless, fatigued, or strained you feel, and that subjective rating often aligns with how your body is actually responding, even though it isn’t a direct measure of heart rate. There are other Borg scales that use different ranges (for example, some scales go up to 20), but the statement about a 0–10 range is a standard and practical way to assess effort. The scale isn’t limited to advanced athletes; it’s a versatile tool for beginners as well.
