    Purpose The purpose of this study was to validate of a Thai translated version of OMNI cycle ergometer exercise scale of perceived exertion among young healthy females (N = 17) (18-25 yrs). Methods Heart rate (HR, b/min), oxygen consumption (VO2, L/min), minute ventilation (VE, L/min), respiratory rate (RR, b/min) and ratings of perceived exertion (OMNI cycle Scale; RPE) for the overall body (RPE-O), legs (RPE-L), and chest (RPE-C) were determined at the end of each of 3-min exercise stages in continuously administered exercise tests. Power output (PO) of cycling intensity started at 25 Watt (w) with 25 w incremented in every stage. Subjects performed the exercise test up to 100 w. Results Exercise responses range was for HR: 99.9-153.9 b/min; VO2: 14.20-26.58 ml/kg/min; VE: 15.1-41.7 L/min; RR: 22.3-33.2 b/min and OMNI RPE RPE-O, RPE-L, and RPE-C: 0.8-7.1. Linear regression analyses showed that RPE-O, RPE-L and RPE-C distributed as a positive linear function for all criterion measures (HR, VO2, VE, and RR) (p < 0.01). Correlation between RPE and HR (r: 0.74-0.79, p < 0.01), RPE and VO2 (r: 0.79- 0.80, p < 0.01), RPE and VE (r: 0.82-0.83, p < 0.01), and RPE and RR (r: 0.47-0.49, p < 0.01) were statistically significant. Two-way ANOVA with repeated measures showed that RPE increased at each exercise stage and RPE-L were higher (p < 0.01) than RPE-O and RPE-C. One-way ANOVA with repeated measures showed that HR, VO2, VE, and RR significantly increased with the progression of workload (p < 0.001). Conclusion The Thai translated version of the OMNI Scale of perceived exertion for cycle ergometer exercise concurrent validity is established for young adult female.
