Comparison of two rating of perceived exertion scales for evaluating training

[摘要] 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 thescales directly. PURPOSE: To compare the BORG-RPE and BORG-CR10 on anintraindividual 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 physiologicalvalues. Subjects then participated in six, varying intensity (two easy, two moderate, twohard), 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 scalesand 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.
