On the Borg scale, which range corresponds to exertion levels (6 to 20)?

• A. 0-10 RPE scale
• B. Dyspnea scale
• C. Talk test
• D. Borg scale

Answer: (D)

The key idea is recognizing the specific range used by a well-known perceived exertion tool. The Borg Rating of Perceived Exertion is defined with a 6 to 20 range, designed so that the numbers roughly map to heart rate (about 10 times the RPE value). This makes it easy to estimate how hard you’re working without equipment—6 representing no exertion and 20 representing maximal effort. The other options describe different methods for gauging intensity (a 0–10 RPE is a separate scale, a Dyspnea scale measures breathlessness, and the talk test uses speech comfort). So the reference that uses the 6–20 range is the Borg scale.
