“…This investigation broadens the findings of (Kang et al, 2003) by having subjects perform continuous exercise at two different intensities. Using an estimation -production protocol, Kang et al, 2003 determined that subjects could self-regulate their exercise intensity on the treadmill using the OMNI RPE scale for a continuous 20 minute exercise bout.…”

“…Various scaling metrics have been shown to be valid in establishing and maintaining exercise intensity during steady state aerobic exercise ranging from 8 -25 minutes in duration (Dunbar et al, 1992;Dunbar et al, 1994;Kang et al, 2003). The next logical step is to examine if RPE can be used to regulate exercise intensity during an intermittent training bout.…”

“…Investigators using the same estimation-production protocol as (Kang et al, 2003) examined the ability of male and female subjects to use RPE to regulate arm and leg ergometry during five minutes of exercise (Kang et al, 1998). The study performed only intramodal comparisons.…”

“…Subsequent validation studies have been completed on adult male and females and for a range of exercise modalities (Gairola et al, 2006;Groslambert et al, 2005;Kang et al, 1998;Kang et al, 2003;Pfeiffer et al, 2002;Robertson, Goss, Andreacci, Dube, Rutkowski, Frazee et al, 2005;Robertson et al, 2002;Robertson et al, 2001;Robertson et al, 2000;Robertson et al, 2004;Robertson et al, 2003;Utter et al, 2006;Utter et al, 2004;Utter et al, 2002) The OMNI rating of perceived exertion scale has demonstrated both concurrent and construct validity for weight bearing exercise for men and women during walking and running exercise (Utter et al, 2004). A concomitant increase in OMNI RPE and respiratory-metabolic measures provided the basis for concurrent validation.…”

“…The results of the Chow et al (1984) study indicated that RPE scaling metrics can be used to maintain a constant exercise intensity for durations of 15 to 20 minutes. In addition, the OMNI RPE scale has recently been established as a valid instrument for regulating exercise intensity during longer exercise bouts on both the cycle ergometer and the treadmill (Kang et al, 2003;Utter et al, 2006).…”

The primary purpose of this investigation was to determine if college age males and females (18 to 25 year old) can self-regulate exercise intensity during a 20 minute intermittent bout of aerobic exercise on the treadmill using the OMNI RPE scale. All subjects completed an estimation trial (EST) graded exercise test using the Bruce protocol to measure heart rate (HR), oxygen consumption (VO 2 ), and rating of perceived exertion (RPE) every minute until exhaustion. Using data from the EST, target RPEs corresponding to 50% and 70% of VO 2 R were determined via regression analysis. A production trial (PROD) was then performed in which subjects titrated speed and grade on the treadmill to elicit the target RPEs corresponding to 50% and 70% of VO 2 R in counterbalance order. At an RPE corresponding to 50% of VO 2 R, HR and VO 2 were significantly higher in the PROD compared to the EST for counterbalance order I (70% -50%) (p < .001). However, there was no significant difference in HR and VO 2 between the EST and PROD for counterbalance order II (50% -70%) (p > .05). When subjects exercised at an RPE corresponding to 70% of VO 2 R, the HR was significantly higher in the PROD compared to the EST for counterbalance order I (70% -50%), (p < .05). However, there was no significant difference in HR between the EST and PROD trials for counterbalance order II (50% -70%), (p >.05). At an RPE corresponding to 70% of VO 2 R, there was no significant difference in the VO 2 between the EST and PROD trials (p > .05). Subjects were also able to perceptually differentiate between the two target RPEs corresponding to 50% and 70% of VO 2 R iv as indicated by the significant difference in HR (p < .05) and VO 2 (p < .05) between the two prescribed PROD RPE intensities. The present investigation indicates that subjects were able to use RPE to self-regulate exercise intensity during 20 min of exercise at varying intensity when starting the exercise bout at the RPE corresponding to 50% of VO 2 R.

The validity of predicting maximal oxygen uptake from a perceptually-regulated graded exercise test

et al. 2005

The purpose of this study was to assess the validity of predicting maximal oxygen uptake(VO(2max)) from sub-maximal VO(2) values elicited during a perceptually-regulated exercise test. We hypothesised that the strong relationship between the ratings of perceived exertion (RPE) and VO(2) would enable VO(2max) to be predicted and that this would improve with practice. Ten male volunteers performed a graded exercise test (GXT) to establish VO(2max) followed by three sub-maximal RPE production protocols on a cycle ergometer, each separated by a period of 48 h. The perceptually-regulated trials were conducted at intensities of 9, 11, 13, 15 and 17 on the RPE scale, in that order. VO(2) and HR were measured continuously and recorded at the end of each 4 min stage. Individual's RPE values yielded correlations in the range 0.92-0.99 across the three production trials. There were no significant differences between measured VO(2max) (48.8 ml.kg(-1).min(-1)) and predicted VO(2) max values (47.3, 48.6 and 49.9 ml.kg(-1).min(-1), for trials 1, 2 and 3, respectively) when VO(2) max was predicted from RPE values of 9-17. The same was observed when VO(2max) was predicted using RPE 9-15. Limits of agreement (LoA) analysis on actual and predicted VO(2max) values (from RPE 9-17) were (bias+/-1.96xSDdiff) 1.5+/-7.3, 0.2+/-4.9 and -1.2+/-5.8 ml.kg(-1).min(-1), for trials 1, 2 and 3, respectively. Corresponding LoA values for actual and predicted VO(2max) (from RPE 9-15) were 5.4+/-11.3, 4.4+/-8.7 and 2.3+/-8.4 ml.kg(-1).min(-1), respectively. The data suggest that a sub-maximal, perceptually-guided, graded exercise protocol can provide acceptable estimates of maximal aerobic power, which are further improved with practice in fit young males.
