Rating Of Perceived Exertion In Cycle Ergometer
Medicine & Science in Sports & Exercise
Aim: Th e purpose of this study was to evaluate cardiopulmonary responses of individuals with diff erent fi tness levels according to predetermined rating of perceived exertion (RPE) scores and to investigate the correspondence between the heart rate reserve percentage (HRR%) and the RPE scale by using fi t and unfi t subjects. Materials and methods: RPE scores of sedentary volunteers were recorded at diff erent HRR% levels during graded exercise tests on a cycle ergometer. Following the tests,
... ollowing the tests, subjects were divided into 2 groups, high metabolic equivalent [(MET) MET ≥ 10; n = 9] and low MET (MET < 10; n = 11), according to maximal O 2 uptakes (VO 2max ). Participants performed the steady-state exercise test at the 13th-14th level of their perceived exertion 48 h aft er the fi rst test. Variance and regression analyses were performed. Results: For all HRR% values, RPE levels were not diff erent between groups. During the graded exercise test, perceived exertion was signifi cantly higher in the low MET group than in the high MET group. Predetermined RPE score results were signifi cantly greater in the low MET group with relative O2 consumption as compared to the high MET group (P < 0.05-0.001). Conclusion: In individuals with diff erent VO 2max levels, exercise intensity can be prescribed using HRR% or RPE scale methods while adjusting for individual diff erences in oxygen consumption.
