Objective[edit | edit source]
Borg rating of perceived exertion (RPE) is an outcome measure scale used in knowing exercise intensity prescription. It is use in monitoring progress and mode of exercise in cardiac patients as well as in other patient population undergoing rehabilitation and endurance training.
Borg RPE scale was developed by Gunnar Borg[1] for rating exertion and breathlessness during physical activity; that is, how hard the activity is as shown by high heart and respiration rate, profuse perspiration and muscle exertion.
Versions And Scoring[2][edit | edit source]
Borg original version is a scale of 6-20 and it has a high to correlation heart rate. It was later reconstructed to category (C) ratio (R) scale, termed Borg CR10 Scale or modified Borg Dyspnoea Scale which is mostly used in diagnosis of breathlessness and dyspnea, chest pain, angina and musculo-skeletal pain. The CR-10 scale is best used in a specific area of the body sensation such as muscle pain or from pulmonary responses.
| Borg RPE Scale | Borg CR10 Scale | |||
|---|---|---|---|---|
| Scoring | Level of Exertion | Scoring | Level of Exertion | |
| 6 | No Exertion | 0 | No Exertion | |
| 7 | Extremely Light | 0.5 | Very very Slight | |
| 8 | 1 | Very Slight | ||
| 9 | Very Light | 2 | Slight | |
| 10 | 3 | Moderate | ||
| 11 | Light | 4 | Somewhat Severe | |
| 12 | 5 | Severe | ||
| 13 | Somewhat Hard | 6 | ||
| 14 | 7 | Very Severe | ||
| 15 | Hard(Heavy) | 8 | ||
| 16 | 9 | Very very Severe | ||
| 17 | Very Hard | 10 | Maximal | |
| 18 | ||||
| 19 | Extremely Hard | |||
| 20 | Maximal Exertion | |||
In Borg RPE,
9 connotes ‘very light’ exercise which equals walking slowly for few minutes at own pace of a healthy individual..
13 depicts ‘somewhat hard’ but the individual is still able to continue the activity.
17 connotes ‘very hard’. A healthy person can continue but must push themselves beyond their comfort of being very fatigued.
19 is extremely strenuous exercise.for most people, the hardest they have ever experienced.
Intended Population[edit | edit source]
It is intended for all patient under rehabilitation. and for monitoring exercise prescription in athletes.It may not be suitable for children's use as the scoring is difficult to interpret in this age group.
Method of Use[edit | edit source]
The scale is a very simple numerical list. Participants are asked to rate their exertion on the scale during the activity, combining all sensations and feelings of physical stress and fatigue. They are told to disregard any one factor such as leg pain or shortness of breath but to try to focus on the whole feeling of exertion. This number gives an indication of the intensity of activity allowing the participant to speed up or slow down movements. The scale takes seconds to complete and can be researcher or self-administered and used on a single occasion or multiple times.
Evidence[edit | edit source]
Reliability[edit | edit source]
Testing of the subject twice was used in ascertaining reliability was used in study done and Borg RPE was found to be reliable in rating exertion[3][4]
Validity[edit | edit source]
Borg RPE scores were positively associated with heart rate in adults during exercise sessions using the Wii Fit Plus.[5]
Skinner et al, found no significant differences in any of the physiological and perceptual variables in work intensity when the work load was presented in a random order and compared with those obtained during the progressive exercise test.[3]
