Comparison of two rating of perceived exertion scales for evaluating training

By Blaine Arney


The Borg 6-20 Rating of Perceived Exertion (BORG-RPE) and Category-Ratio 10 (BORG-CR10) scales are the most well-known and widely used Rating of Perceived Exertion (RPE) scales in the field of exercise. However, no studies have compared the scales directly. PURPOSE: To compare the BORG-RPE and BORG-CR10 on an intraindividual level in varying training sessions using concurrent validity, verbal anchor and numerical categorical comparisons. METHODS: Fourteen subjects completed an initial maximal incremental exercising testing to determine maximal physiological values. Subjects then participated in six, varying intensity (two easy, two moderate, two hard), interval exercise sessions. The BORG-RPE and BORG-CR10 were used separately on different occasions for each exercise intensity. Regression analysis was used to determine concurrent and construct validity of the two scales. RESULTS: A strong non- linear correlation was identified between the two scales (r = .95). Strong, linear correlations were identified between both scales and heart rate [BORG-RPE (r = .85); BORG-CR10 (r = .83)]. Good, linear correlations were identified between both scales and blood lactate [BORG-RPE (r = .74); BORG-CR10 (r = .78)]. CONCLUSION: A high degree of equivalence and interchangeability was identified between the BORG- RPE and BORG-CR10 for perceived effort during exercise training
