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 (p < .05) positive linear function (r = .81–.92) for all physiological measures. OMNI-RPE was positively (p < .01) and linearly related to Borg-RPE in elderly men (r = .97) and women (r = .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.

The purpose of this study was to examine the concurrent and construct validity of the Borg (0–10) and children’s OMNI scales for quantifying the exercise intensity and training load (TL) in youth soccer players.


Twelve children (mean ± SD age 11.4 ± 0.5 y, height 154.3 ± 6.5 cm, body mass 39.5 ± 5.4 kg) took part in this study. Exercise intensity and TL were calculated on the basis of the session rating of perceived exertion (sRPE) and heart rate (HR; Edwards method) during 20 technical-tactical training sessions. Players’ sRPEs were obtained from the Borg and OMNI scales.


Low correlations between HR-based TL and sRPE TL based on the Borg (r = .17, P = .335) and OMNI (r = .34, P = .007) scales were obtained. Significant (P < .001) relationships in sRPE (r = .76) and TL (r = .79) between RPE scales were found.


The current data do not support the relationship between the sRPE and HR methods for quantifying TL in youth soccer players. However, the sRPE method could be considered a better indicator of global internal TL, since sRPE is a measure of both physical and psychological stress. In addition, the authors demonstrated the construct validity for the OMNI scale to control exercise demands.

The purpose of this investigation was to determine whether either the differentiated ratings of perceived exertion (RPE) for the legs (RPE-L) or chest (RPE-C) were higher than the overall body RPE (RPE-O) in children performing treadmill walking. A differentiated RPE that was higher than the RPE-O was considered the dominant perceptual signal. Thirty-one 10-year-old participants (16 boys, 15 girls) performed six separate 5-min bouts of level treadmill walking at different speeds. During each bout of exercise, RPEs were recorded using the modified Children’s OMNI Scale. Oxygen consumption (VO2), heart rate (HR), and ventilation (VE) were measured during Minutes 4 and 5 at each walking speed. VO2, HR, and VE increased as walking speed increased, as did perceived exertion. No differences were observed among RPE-O, RPE-L, and RPE-C at any speed. In addition, boys and girls exhibited similar responses for each perceptual and physiological variable. In conclusion, a dominant differentiated perceptual rating was not found at slow-to-moderate treadmill walking speeds for either boys or girls. Neither the respiratory–metabolic nor peripheral ratings of perceived exertion appeared to dominate the whole-body sensory-integration process in this sample.
