PURPOSE: The purpose of this project was to examine concurrent and construct validity of two newly developed Adult OMNI Elliptical Ergometry ratings of perceived exertion (RPE) Scales. METHODS: Fifty-nine sedentary to recreationally active, college-aged volunteers (males, n = 30; age = 21.3 + 3.3 yrs and females, n = 29; 22.3 + 3.5 yrs) participated in this study. A single observation, cross-sectional perceptual estimation trial was employed with subjects exercising to volitional fatigue on an elliptical ergometer. Oxygen consumption (VO2), heart rate (HR) and RPE-Overall Body (O), Legs (L) and Chest/Breathing (C) were recorded each stage from the Borg 15 Category Scale and two different OMNI RPE scale formats. One scale maintained the original format of the OMNI Picture System of Perceived Exertion. The second scale modified verbal, numerical and pictorial descriptors at the low end of the response range. Concurrent validity was established by correlating RPE-O, L and C from each scale with VO2 and HR obtained from each test stage during the estimation trial. Construct validity was established by correlating RPE-O, L and C from the Adult OMNI Elliptical Ergometry Scales with RPE-O, L and C from the Borg Scale. RESULTS: Correlation analyses indicated the relation between RPE-O, L and C from each OMNI RPE Scale distributed as a positive linear function of both VO2 (males, r = .941 - .951 and females, r = .930 - .946) and HR (males, r = .950 - .960 and females, r = .963 - .966). A strong, positive relation was also exhibited between differentiated and undifferentiated RPE from the Adult OMNI Elliptical Ergometry Scales and the Borg 15 Category Scale (males, r = .961 - .972 and females, r = .973 - .977). CONCLUSION: Concurrent and construct validity were established for both formats of the Adult OMNI Elliptical Ergometry Scale during partial weight bearing exercise. Either scale can be used to estimate RPE during elliptical ergometer exercise in health-fitness settings. However, because of the potential use of RPE in caloric expenditure indices and prediction models, the modified scale depicting the "rest" pictorial may be more practical.
