    © 2014, Medical Association of Thailand. All rights reserved. Objective: To investigate the relationship among metabolic equivalents of an exercise stress test (METs of EST), demographic parameters (age, body weight, height, BMI), peak oxygen consumption (VO2 peak), and six-minute walk distances (6MWD) determined from a six-minute walk test (6MWT). Material and Method: Exercise capacity was estimated by a 6MWT and EST at the sixth week post operation in post coronary artery bypass graft (post CABG, n = 17) and post percutaneous coronary intervention (post PCI, n = 13) patients. Results: METs of EST showed: high correlation (p<0.01) with VO2 peak of 6MWT (r = 0.94), 6MWD (r = 0.92); muscle strength (r = 0.78), moderate correlation (p<0.01) with height (r = 0.53); negative correlation with age (r = -0.50). Low correlation was found (p<0.05) with step length (r = 0.43), and weight (r = 0.38). No correlation was found among METs of EST and rating perceived exertion (RPE) of EST and 6MWT. The multiple linear regression equation for explaining METs of EST is as follows: METs of EST = -2.94+0.02 (6MWD), (r = 0.923, R2 = 0.85, p<0.001). Conclusion: The 6MWT may possibly be used as an alternative choice for estimating energy expenditure to design exercise programs for these post operation groups.

    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.
