“…The influence of fitness, activity and athletic experience on the application of the RPE has been equivocal, with some studies reporting that fit individuals report lower RPE values (Hassmen 1990;Travlos and Marisi 1996), or no difference in RPE values (Demello et al 1987;Felts et al 1988;Mihevic 1983;Parfitt et al 1996;Winborn et al 1988) when compared to unfit individuals. Previous research has also provided inconsistent evidence regarding the influence of gender on the use of the RPE (Demello et al 1987;Eston et al 1987Eston et al , 2006Parfitt et al 1994;Purvis and Cureton 1981).…”

This study assessed whether the accuracy of predicting maximal oxygen uptake (VO2max) from sub-maximal heart rate (HR) and ratings of perceived exertion (RPE) values was moderated by gender and habitual activity. In total, 27 men and 18 women completed two GXTs to determine VO2max and three perceptually-regulated GXTs, incremented by RPE 9, 11, 13, 15 and 17. The RPE and HR were individually regressed against VO2max (approximately 0.96) to enable predictions of VO2max. The VO2max was predicted from three RPE ranges (9-17, 9-15, 9-13). The RPE ranges were extrapolated to RPE(19), RPE(20) and age-predicted maximal HR (HRmax(pred)). ANOVA revealed no differences between measured and predicted VO2max (P > 0.05) when the RPE range 9-17 was extrapolated to RPE(19) and HRmax(pred). Extrapolation of RPE 9-17 to RPE(20) overestimated VO2max (P < 0.05), but no differences were observed when predicted from the RPE ranges 9-15 and 9-13. The prediction of VO2max was not moderated by gender or activity status. Hierarchical regression analysis revealed that HR explained additional variance in VO2max when added to the RPE (2%). Hierarchical multiple regression analysis also indicated that VO2max was significantly correlated with power output at sub-maximal RPE values of 13 and 15 (P < 0.01) in men and women. The addition of HRmax(pred) improved the accuracy of the prediction equation for men (P = 0.05) but not for women. The study confirmed the validity of estimating VO2max from perceptually-regulated, sub-maximal GXT and indicated the potential utility of regression analysis to gauge appropriate sub-maximal exercise intensities.

“…Fit individuals have been reported to exhibit lower RPE (DeMello et al 1987;Hassmen 1990;Travlos and Marisi 1996) or no difference in RPE (Mihevic 1983;DeMello et al 1987;Felts et al 1988;Winborn et al 1988) when compared with unfit individuals at a given relative exercise intensity. Travlos and Marisi (1996) observed that highly fit individuals (>56 ml kg À1 min À1 ) reported lower RPE than individuals who were low in fitness (<46 ml kg À1 min À1 ) at 10-min workloads on a cycle ergometer corresponding to equivalent exercise intensities of 40, 50, 60, 70 and 80% of _ VO 2max : Conversely, Mihevic (1983) reported that there are no differences in RPE between groups of high and low fitness during short duration, low-moderate exercise intensities.…”

This study assessed the relationship between differentiated ratings of perceived exertion (RPE) and heart rate with oxygen uptake (VO2) during two graded exercise tests (GXT) to exhaustion on a cycle ergometer in 49 men and women (19-50 years) of high and low fitness. The study also assessed whether sub-maximal RPE values elicited during the GXTs could provide appropriate estimates of maximal aerobic power (VO2max) Peripheral RPE (RPEP) was higher than overall RPE (RPEO) at exhaustion in both groups (P<0.001), but the reliability of the terminal RPEO was higher (0.75 and 0.40, respectively). Fitness did not moderate the relationship of RPEO and RPEP with VO2 during the GXTs (P>0.05). However, the correlation for RPEP and VO2 was higher for women compared to men (0.98 and 0.96, respectively, P<0.05), although this is of little practical significance. In both groups, RPEO was almost as highly correlated with VO2 as heart rate during GXTs terminated at exhaustion (approximately 0.955-0.980). There were no differences between predicted and measured VO2max when VO2 values were extrapolated from sub-maximal RPEO (13, 15 and 17) intensities (42.1+/-12.5, 43.4+/-11.5, 44.2+/-11.3 and 43.3+/-10.0 ml kg(-1) min(-1), respectively). However, VO2max predicted from sub-maximal RPEP intensities was significantly lower (P<0.05). In conclusion, terminal RPEO was a more reliable measure of the RPE, and provided more accurate estimates of VO2max in healthy participants of high and low fitness when elicited from sub-maximal exercise intensities.

“…The result is almost consistent with Tikuisis et al (2002)'s findings who observed that the PeSI was not completely dominated by RPE in trained group where fRPE ranged from 40% to 55%. In the present study, all participants performing sports frequently per week may be treated as trained individuals so that they might be not sensitive to perceived exertion (Mihevic, 1983). Work uniform A (with better heat-moisture transfer capability) provided a pleasant thermal sensation that resulted in significantly lower perceptual strain levels than uniform B.…”
