“…Mahon et al (1998) showed that RPE at VT was 11.5Ϯ2.6 during pedaling for adults. Thus, it could be said that our speculations regarding the exercise intensities at each stage from viewpoint of BLa and RPE are not so far from the previous studies (Boutcher et al, 1989;Mahon et al, 1998;Purvis and Cureton, 1981).…”

“…Regarding the RPE, it was 11.5Ϯ1.1 in the 1st stage, 13.2Ϯ1.7 in the 2nd stage and 14.9Ϯ2.2 in the 3rd stage in pedaling and 9.8Ϯ1.6 in the 1st stage, 11.3Ϯ1.1 in the 2nd stage and 12.2Ϯ1.0 in the 3rd stage for running. Boutcher et al (1989) observed that RPE at LT were from 9.0Ϯ2.6 to 10.6Ϯ3.0 in pedaling and from 10.4Ϯ2.4 to 12.0Ϯ3.7 during running for males. Purvis and Cureton (1981) reported that RPE at the ventilatory threshold (VT) was 14.2Ϯ0.9 for males during pedaling.…”

The purpose of this study was to evaluate the differential perceived exertion measured using a new set of Visual Analogue Scales (VAS) during pedaling and running. The subjects were eleven healthy males. They performed an incremental maximal test and then three 4-min stages of exercise, for both pedaling and running. During the tests, Vo 2 , V CO 2 , V E , f, and HR were monitored continuously. Bla and perceptual variables including VAS consisting of four scales (VAS 1-VAS 4) and Borg's RPE were measured at the end of each stage. Although the V O 2 (%V O 2 max ) and HR for both pedaling and running were not significantly different, Bla in pedaling was significantly higher than that in running. A significant interaction (mode, stage) was also obtained. The VAS 1 of pedaling was significantly higher than that of running. A significant interaction in VAS 1 (mode, stage) was obtained. The VAS 2 of pedaling was significantly higher than that of running. The subjects indicated that local pain became stronger than central pain in pedaling, but they were almost equal in running. In both pedaling and running, leg pain became stronger than arm pain (VAS 3). VAS 4 showed that during running, breathing difficulty and heart pain were almost equal in perceived intensity. However, during pedaling, breathing difficulty became greater than heart pain. Thus, a new four-part visual analogue scale was found to be useful for monitoring exercise intensity. In addition, the new VAS gave us more information in relation to the differential perceived exertion reflected in the different physiological responses obtained by different exercise modes.

“…It is known that RPE is actually more strongly coupled with blood lactic acid accumulation thresholds than with %HRmax or %VO 2 max. [31][32][33][34][35][36] The more highly trained individual will work to a greater proportion of HRmax or VO 2 max for a given blood lactate but the RPE at this given blood lactate will be the same in the trained and less trained individual.…”

Reliability and validity of measures taken during the Chester step test to predict aerobic power and to prescribe aerobic exercise

et al. 2004

Objectives: To evaluate the reliability and validity of measures taken during the Chester step test (CST) used to predict VO 2 max and prescribe subsequent exercise. Methods: The CST was performed twice on separate days by 7 males and 6 females aged 22.4 (SD 4.6) years. Heart rate (HR), ratings of perceived exertion (RPE), and oxygen uptake (VO 2 ) were measured at each stage of the CST. Results: RPE, HR, and actual VO 2 were the same at each stage for both trials but each of these measures was significantly different between CST stages (p,0.0005). Intertrial bias ¡95% limits of agreement (95% LoA) of HR reached acceptable limits at CST stage IV (22¡10 beats/min) and for RPE at stages III (0.2¡1.4) and IV (0.5¡1.9). Age estimated HRmax significantly overestimated actual HRmax of 5 beats/min (p = 0.016) and the 95% LoA showed that this error could range from an underestimation of 17 beats/min to an overestimation of 7 beats/min. Estimated versus actual VO 2 at each CST stage during both trials showed errors ranging between 11% and 19%. Trial 1 underestimated actual VO 2 max by 2.8 ml/kg/min (p = 0.006) and trial 2 by 1.6 ml/kg/min (not significant). The intertrial agreement in predicted VO 2 max was relatively narrow with a bias ¡95% LoA of 20.8¡3.7 ml/kg/min. The RPE and %HRmax (actual) correlation improved with a second trial. At all CST stages in trial 2 RPE:%HRmax coefficients were significant with the highest correlations at CST stages III (r = 0.78) and IV (r = 0.84). Conclusion: CST VO 2 max prediction validity is questioned but the CST is reliable on a test-retest basis. VO 2 max prediction error is due more to VO 2 estimation error at each CST stage compared with error in age estimated HRmax. The HR/RPE relation at .50% VO 2 max reliably represents the recommended intensity for developing cardiorespiratory fitness, but only when a practice trial of the CST is first performed.T he Chester step test (CST) was originally developed by Kevin Sykes at University College Chester to assess aerobic fitness by predicting maximal aerobic power (VO 2 max) in fire brigades in Britain, Europe, USA, and Asia, and more recently for work with airport firefighters, the ambulance service, health authorities, and corporate institutions.1 It also features in commercial health and fitness assessment packages and most noticeably one in particular (Fitech Pty Ltd, Australia; www.fitech.com.au). The CST is one of many tests designed to provide a safe and practical means of assessing aerobic fitness under submaximal conditions. Examples of other similar tests include the Astrand-Ryhming nomogram cycle ergometer protocol, 2 the American College of Sports Medicine protocols for cycle ergometry and treadmill, 3 and the Canadian standardised step test of fitness. 4 The limited equipment needed (step, heart rate monitor, portable cassette or compact disk player, and perceived exertion scale) makes the CST very portable and requirements for space are minimal, which is advantageous compared with similar protocols using treadmills, shutt...

The purpose of the present investigation was 1) to study the effects of fitness level on perceived exertion (RPE) and estimated time limit (ETL) scales during exhausting runs, and 2) to predict time to exhaustion from RPE or ETL values collected during a constant run exercise. Eight high-fitness level and twelve moderate-fitness level endurance trained males performed two exhausting exercises on a 400-m running track. The first test was a graded exercise using a portable metabolic system to determine maximal oxygen uptake (V.O (2)max), the velocity associated with V.O (2)max (vV.O (2)max), the velocity at the lactate threshold (vLT) and the velocity at delta 50 (vDelta50 : the velocity halfway between vV.O (2)max and vLT). The second test was a constant run exercise at vDelta50 to determine the time to exhaustion at this intensity (tlimvDelta50). Moderate-fitness level athletes perceived exercise to be relatively more strenuous and felt that they could continue for less time than high-fitness level athletes at similar relative velocities. There was no effect of fitness level on perceived exertion for a given relative exercise duration. RPE corresponding to vLT was not statistically significantly different between the two levels groups. For the two groups, measured and predicted exhaustion time values, which were calculated from linear extrapolation of RPE and ETL values collected during the first 4 minutes of a submaximal constant run exercise, were not statistically significantly correlated. These results indicate that the aerobic fitness level seems to influence perceived exertion only during graded exercise. Consequently, if RPE is used to prescribe an exercise intensity, the prescription must be individualised regarding the aerobic fitness level of the athlete except for exercise intensities corresponding to vLT. Moreover, the perceived exertion pattern at the beginning of a submaximal constant run exercise could not be considered as a sensitive predictor of the point of self-imposed exhaustion whatever the fitness level of the athletes.
