Rating of perceived exception

from Wikipedia, the free encyclopedia

In sport, and especially in stress tests, the Rating of Perceived Exertion (RPE) , measured using the Borg scale for physical exertion (RPE scale), is a frequently used quantitative measure of the perceived exertion during physical activity. In medicine, this is used to document the patient's exertion during a test. Sports coaches use the scale to assess the intensity of training and competition. The original scale developed by Gunnar Borg shows the effort on a scale from 6–20. Borg then constructed a category (English: Category, C) ratio (English: Ratio, R) scale, the Borg CR10 scale. It is mainly used in clinical diagnostics for breathlessness and dyspnea , chest pain , angina pectoris and pain in the musculoskeletal system.

The Borg scale is comparable to other linear scales such as the Likert scale and the visual analog scale . The sensitivity and reproducibility of the results are for the most part very similar, however the Borg scale outperforms the Likert scale in some cases.

Importance of values

The Borg RPE scale is a numeric scale that ranges from 6 to 20. The rating 6 stands for "no effort at all" and the rating 20 for "maximum effort". In order to carry out a measurement, a value is chosen that best describes the exertion during a physical activity carried out. For the conception of the scale, the values ​​were set in such a way that the Borg value multiplied by 10 roughly corresponds to the heart rate of a young, healthy test person.

  • 6 - No effort
  • 7 - Extremely light
  • 8th
  • 9 - Very easy
  • 10
  • 11 - Easy
  • 12
  • 13 - A little difficult
  • 14th
  • 15 - Difficult
  • 16
  • 17 - Very difficult
  • 18th
  • 19 - Extremely difficult
  • 20 - Maximum effort

Use in strength training

Traditionally, the rating of perceived exertion was used to measure exertion and to regulate the intensity during aerobic exercise. More recently, however, RPE-based methods have also been used for intra-training feedback on the perceived exertion during explosive strength training. This is intended to enable exercisers to control the intensity in such a way that the power output can be maximized and the total fatigue of a single workout can be measured.
