Description

<jats:p>This study examined the concurrent and construct validity of the OMNI-Cycle Rating of Perceived Exertion (RPE) Scale, using elderly men and women. Seventy-six participants performed a load-incremented cycle-ergometer exercise test. Concurrent validity was determined by correlating OMNI-RPE responses with oxygen uptake, relative peak oxygen uptake, pulmonary ventilation, heart rate, respiratory rate, and respiratory-exchange ratio during a load-incremented cycle-ergometer protocol. Construct validity was established by correlating RPE derived from the OMNI-Cycle Scale with RPE from the Borg (6–20) Scale. Multilevel, mixed linear-regression models indicated that OMNI-RPE distributed as a significant (<jats:italic>p</jats:italic> < .05) positive linear function (<jats:italic>r</jats:italic> = .81–.92) for all physiological measures. OMNI-RPE was positively (<jats:italic>p</jats:italic> < .01) and linearly related to Borg-RPE in elderly men (<jats:italic>r</jats:italic> = .97) and women (<jats:italic>r</jats:italic> = .96). This study demonstrates both concurrent and construct validity of the OMNI-Cycle RPE Scale. These findings support the use of this scaling metric with elderly men and women to estimate RPE during cycle-ergometer exercise.</jats:p>
