Abstract: Purpose: The purpose of the study is to examine the concurrent and construct validity of the 10-Point OMNI Rating of Perceived Exertion (RPE) Colored Scale (OMNI-Color) in young adult women and men (18 – 25 yr). Methods: 10 male and 10 female clinically normal adults participated in the study. A cross-sectional, perceptual estimation design was used to assess exertional perceptions during a load-incremented cycle ergometer protocol that terminated at peak exercise intensity on 2 separate trials, 1 week apart. During each of the trial, subjects will be assigned to use either the OMNI-Color Scale or the Adult Omni Scale of Perceived Exertion for Cycle Ergometer Exercise (OMNI-Cycle) in a crossover randomized manner. RPE, VO2 and HR were measured during the last minute of each three-minute exercise stage. Results: For both gender groups, linear regression analyses indicted that RPE derived from the the OMNI-Color Scale distributed as a positive linear function of VO2 and HR for the first 4 stages (r = 0.97 to 0.99; P < 0.05), and when comparing all power output (PO) stages (r = 0.98 to 0.99; P < 0.05). RPE derived from the OMNI-Color Scale distributed as a linear function of the OMNI-Cycle Scale for the first 4 stages (r = 0.997 to 0.998; P < 0.01) and for all PO stages ( r = 0.996 to 0.998; P < 0.01) for both genders. Conclusion: Concurrent and construct evidence supports use of OMNI-Color Scale by adult women and men to estimate RPE during cycle exercise.
