Relationship of the Borg 6~20 Scale and OMNI Scale of Perceived Exertion and Physiological Response in Men

[[abstract]]Purpose: The purpose of this study was to investigate the RPE value and the relationship of physiological responses in comparing Borg 6~20 scale and OMNI scale during the exhaustive exercise on bicycle ergometer. Methods: 30 healthy males students (age: 20.03 ± 2.22 years; height: 175.37 ± 4.57 cm; weight: 70.57 ± 7.33 kg; BMI: 22.91 ± 1.85 kg/m2) of the Department of Physical Education were tested in this study. Each testing subject used Borg 6~20 scale and OMNI scale respectively by counter-balance design, and did the testing of the exhaustive exercise on bicycle ergometer. Heart rate, ventilation, oxygen consumption, respiratory exchange rate, and RPE value of every subject during each stage were measured when exercising. Pearson’s correlation was applied to get the correlation between RPE value of two kinds of scales and physiological responses. Dependent t-test was applied to compare the correlation between two kinds of scales. Results: The RPE value of the two scales were significantly correlated with heart rate, ventilation, oxygen consumption and respiratory exchange rate ( p<.05). And the correlation coefficients were not significantly different between the two kinds of scales. Conclusion: The Borg 6~20 scale and OMNI scale are all good for identifying exercise intensity for adults during incremental exercise testing.
