Borg's Rating of Perceived Exertion (RPE) is a numerical scale that ranges from 6 to 20. This scale is used to measure the intensity of an individual's exercise based on how they perceive their effort. Each number corresponds to a different level of exertion:
- 6: No exertion at all
- 7-8: Extremely light
- 9-10: Very light
- 11: Light
- 12-13: Somewhat hard
- 14-16: Hard
- 17: Very hard
- 18-19: Extremely hard
- 20: Maximal exertion
A rating of 17 on this scale corresponds to "Very Hard" effort. This indicates a high level of exertion, typically the point at which the activity is significantly challenging and strenuous.
Given the multiple-choice options:
- Option A: Very Light
- Option B: Light
- Option C: Somewhat Hard
- Option D: Very Hard
The correct answer corresponding to a Borg RPE of 17 is clearly Option D:
Very Hard
