Testo completoAbstract (sommario):
The Rating of Perceived Exertion (RPE) is an important measure of exercise intensity, which is useful both as a primary and adjunctive method of exercise prescription. However, there are multiple variants of the Borg RPE scale, primarily the Borg 6-20 RPE scale (BORG-RPE) and the Borg Category-Ratio-10 scale (BORG-CR10). There are inadequate data available to address the comparability and interchangeability of these two widely used scales. Well-trained non-athletes performed two increment cycle tests, with each scale used in a random sequence. Subjects also performed interval sessions at three intensities (50, 75 and 85% of peak power output) with each scale used in a random sequence. There were very large correlations during the incremental exercise between the conventional physiological measures (% heart rate reserve – r=0.89 & r=.87); and %VO2reserve (r=.88 & r=.90) and RPE measured by either the BORG-RPE or the BORGCR10, respectively. This pattern was also evident during the interval exercise (% heart rate reserve (r=.85 & r=.84; and blood lactate concentration – r=.74 & r=.78) and RPE measured by either the BORG-RPE or the BORG-CR10, respectively. The relationship between RPE measured by the BORG-RPE and the BORGCR10 was large and best described by a non-linear relationship for both the incremental (R2=89) and the interval (R2=.89) exercise. The incremental and interval curves were virtually overlapping. We concluded that the two most popular versions of the RPE scale, BORG-RPE and BORG-CR10, were both highly related to the conventional physiological measures and very strongly related to each other, with an easily described conversion.

Testo completoAbstract (sommario):
<p><b>Introduction: </b>The Borg Scale for perceived exertion is well established in science and sport to keep an appropriate level of workload or to rate physical strain. Although it is also often used at moderate and high altitude, it was never validated for hypoxic conditions. Since pulse rate and minute breathing volume at rest are increased at altitude it may be expected that the rating of the same workload is higher at altitude compared to sea level. <p> <b>Material and methods: </b>16 mountaineers were included in a prospective randomized design trial. Standardized workload (ergometry) and rating of the perceived exertion (RPE) were performed at sea level, at 3,000 m, and at 4,560 m. For validation of the scale Maloney-Rastogi-test and Bland-Altmann-Plots were used to compare the Borg ratings at each intensity level at the three altitudes; p < 0.05 was defined as significant. <p><b>Results: </b>In Bland-Altmann-Plots more than 95% of all Borg ratings were within the interval of 1.96 x standard deviation. There was no significant deviation of the ratings at moderate or high altitude. The correlation between RPE and workload or oxygen uptake was weak. <p><b>Conclusion: </b>The Borg Scale for perceived exertion gives valid results at moderate and high altitude – at least up to about 5,000 m. Therefore it may be used at altitude without any modification. The weak correlation of RPE and workload or oxygen uptake indicates that there should be other factors indicating strain to the body. What is really measured by Borg’s Scale should be investigated by a specific study.

Purpose: The session rating of perceived exertion (sRPE) is a well-accepted method of monitoring training load in athletes in many different sports. It is based on the category-ratio (0–10) RPE scale (BORG-CR10) developed by Borg. There is no evidence how substitution of the Borg 6–20 RPE scale (BORG-RPE) might influence the sRPE in athletes. Methods: Systematically training, recreational-level athletes from a number of sport disciplines performed 6 randomly ordered, 30-min interval-training sessions, at intensities based on peak power output (PPO) and designed to be easy (50% PPO), moderate (75% PPO), or hard (85% PPO). Ratings of sRPE were obtained 30 min postexercise using either the BORG-CR10 or BORG-RPE and compared for matched exercise conditions. Results: The average percentage of heart-rate reserve was well correlated with sRPE from both BORG-CR10 (r = .76) and BORG-RPE (r = .69). The sRPE ratings from BORG-CR10 and BORG-RPE were very strongly correlated (r = .90) at matched times. Conclusions: Although producing different absolute numbers, sRPE derived from either the BORG-CR10 or BORG-RPE provides essentially interchangeable estimates of perceived exercise training intensity.

Testo completoAbstract (sommario):
We examined how obese children perceive a maximal cardiorespiratory fitness test compared with a submaximal cardiorespiratory fitness test. Twenty-one obese children (body mass index ≥95th percentile, ages 10–17 years) completed maximal and submaximal cardiorespiratory fitness tests on 2 separate occasions. Oxygen consumption (VO2) and overall perceived exertion (Borg 15-category scale) were measured in both fitness tests. At comparable workloads, perceived exertion was rated significantly higher ( P < 0.001) in the submaximal cardiorespiratory fitness test compared with the maximal cardiorespiratory fitness test. The submaximal cardiorespiratory fitness test was significantly longer than the maximal test (14:21 ± 04:04 seconds vs. 12:48 ± 03:27 seconds, P < 0.001). Our data indicate that at the same relative intensity, obese children report comparable or even higher perceived exertion during submaximal fitness testing than during maximal fitness testing. Perceived exertion in a sample of children and youth with obesity may be influenced by test duration and protocol design.

Testo completoAbstract (sommario):
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.

Testo completoAbstract (sommario):
Tai Chi, yoga, and stretching regimens are gaining popularity as alternatives to more traditional exercise, but there is scant research regarding participants’ perceived exertion and affective responses to these practices. We compared experienced states of perceived exertion, feelings of pleasure/displeasure, and arousal in 70 elderly women enrolled in groups of Tai Chi ( n = 26), yoga ( n = 25), or stretching ( n = 19) classes. Mean rates of perceived exertion, feelings of pleasure, and arousal responses were significantly higher over the time course of all three groups, while the overall mean perceived exertion ( Somewhat Hard on the Borg CR-10 scale) and pleasure responses (∼ Very Good on the Feeling Scale) were similar between them. The circumplex model of affect showed that changes occurred in the high-activation pleasure quadrant (energy on the Felt Arousal Scale). From a practical perspective, the exercise intensity and affective responses elicited during these classes made participants feel good and infused with energy, likely creating a positive memory and reinforcing continued physical activity participation.

Testo completoAbstract (sommario):
Psychophysical approaches to quantifying perceived effort have been used to evaluate the physical demand of many industrial work activities. An experiment was conducted to examine the relationship between ratings of whole-body perceived exertion and differentiated, regional ratings of exertion. The Borg, CR-10 scale was used by 16 subjects performing a simulated repetitive lifting task. Ratings of perceived exertion were obtained for the arms, legs, torso, and central (cardiorespiratory) effort sensations as well as a rating of overall, whole-body exertion. A multiple linear regression analysis was used to predict the whole-body rating of exertion from the differentiated ratings in lifting tasks using both a squat and stoop posture. In the stoop posture condition the coefficient of determination between whole-body perceived exertion and the model including arm, torso, and central ratings was R2=0.81. In the squat posture condition, the final regression model predicting whole-body exertion contained only the rating from the legs (R2 = 0.62). Differentiated ratings explained the majority of the variance in whole-body perceived exertion for squat and stoop lifting tasks.

Testo completoAbstract (sommario):
The Borg Ratings of Perceived Exertion (RPE) Scale has proven to be a highly popular instrument in measuring the subjective responses of individuals to a given work or exercise task. Historically, the instrument was designed to correlate highly with the heart rates in young-to-middle-aged men performing various tasks. The body of literature, however, has revealed inconsistencies in the extent of just how strong the relationship is between ratings of perceived exertion and various physiological criterion variables, most notably, heart rate. In addition, most studies have invoked the question of whether the criterion-related validity coefficients derived from the relationship between ratings of perceived exertion and a specified physiological criterion variable are just as valid as those for which the Borg RPE Scale was originally performed. A meta-analysis, therefore, was undertaken to determine the magnitude of the relationship between ratings of perceived exertion scores and each of three commonly used physiological measures or criterion variables: heart rate, blood lactate, and oxygen uptake. Results show that by using Tests of Homogeneity for each physiological criterion variable, the observed sample size-weighted validity coefficients are heterogeneous. The median of the mean sample size-weighted validity coefficients is .574 for heart rate, .561 for blood lactate, and .480 for oxygen uptake. Each study in the meta-analysis was grouped by the study characteristics of subject gender, fitness level, RPE Scale, exercise type, exercise protocol, and study quality. For heart rate, the highest validity coefficients are those in which the subjects are highly fit, the exercise type is fairly unusual, such as swimming, and the subjects are required to maximally exert themselves. For blood lactate, the highest validity coefficients are for females, healthy-inactive subjects, the 15-point RPE Scale, treadmill use, and swimming. For oxygen uptake, the highest validity coefficients between ratings of perceived exertion and oxygen uptake are for swimming. In a meta-analysis of study effects, when the validity coefficients are analyzed by study, the resultant mean validity coefficients are only somewhat higher (ratings of perceived exertion and heart rate, .657; ratings of perceived exertion and blood lactate, .642; ratings of perceived exertion and oxygen uptake, .609) than those obtained using sample size-weighted validity coefficients. Finally, corrections for bias generally resulted in increased validity coefficients and decreased variances.

Testo completoAbstract (sommario):
O método Pilates, o qual vem se difundindo muito nas últimas décadas, é um método de condicionamento físico que apresenta uma série de exercícios sistematizados os quais podem ser realizados com aparelhos, dotados de molas, submetendo os músculos a cargas externas. Um desses exercícios é o leg work que pode ser caracterizado como uma extensão de quadril e joelhos. Dessa maneira, o conhecimento das forças envolvidas no exercício, bem como seu comportamento, ao longo da amplitude de execução permite uma melhor definição do exercício, contribuindo para uma escolha mais criteriosa e uma melhor prescrição do exercício. Assim, este estudo tem como objetivo identificar a diferença no exercício leg work executado nos aparelhos Chair e Reformer levando em consideração a carga do equipamento (força das molas), a amplitude de movimento (ADM), o ritmo de execução, a atividade eletromiográfica (EMG) de músculos específicos se a sensação subjetiva de esforço das executantes. A amostra foi composta por 18 mulheres fisicamente ativas sem histórico de lesão e praticantes de Pilates há pelo menos 6 meses. Foi empregado diagrama de corpo livre e equações de Newton-Euler para calcular a variação da força externa nos aparelhos Chair e Reformer no movimento leg work. Foi utilizada cinemetria bidimensional (2D) e dois eletromiógrafos para aquisição dos dados. Os músculos analisados foram glúteo máximo (GM), bíceps femoral (BF), vasto lateral (VL), reto femoral (RF), gastrocnêmio medial (GAS), oblíquo externo (OE) e multífido (MU). Os resultados indicam que há diferenças significativas na ativação EMG do OE, VL e RF, no índice de co-contração de BF-RF, BF-VL e OE-MU bem como no índice de esforço percebido entre aparelhos Chair e Reformer durante o movimento leg work. Isso provavelmente se deve a diferenças na ADM e nas estratégias de recrutamento, uma vez que a carga do equipamento final imposta era a mesma em ambos os aparelhos. Essas informações devem ser levadas em consideração em um programa de condicionamento e reabilitação de Pilates. Pode-se concluir que há diferenças no exercício leg work executado nos aparelhos Chair e Reformer na atividade EMG de músculos específicos, ADM e sensação subjetiva de esforço das executantes.The Pilates method, which has been popularized over the last decades, is a physical conditioning method that presents a series of systematized exercises that may be performed by apparatus with springs, loading the muscles to external loads. One of these exercises is the leg work, that may be characterized as hip and knee extension. The knowledge of forces involved in an exercise, as well as their behavior throughout the range of execution allows a better exercise definition, contributing to a more careful choice and a better prescription of the exercise. So, the main goal of this study is to identify the difference between legwork exercise performed on Chair and Reformer apparatus, taking into account external load (spring force), range of motion (ROM), rhythm of execution, specific muscles electromyography (EMG) and subject‟s perceived exertion effort sensation. Eighteen women took part of the study, all physically active, without injury history and practitioners of Pilates for at least six months. Free body diagram and Newton-Euler equations were used in order to calculate external force variation on Chair and Reformer apparatus during the legwork movement. Two-dimensional (2D) kinematics and two electromyography were used for data acquisition. The muscles analyzed were Gluteus Maximum (GM), Biceps Femoris (BF), Vastus Lateralis (VL), Rectus Femoralis (RF), Gastrocnemius (GAS), External Obliquies (EB) and Multifidus (MU). Results indicate that there are significant differences in EMG activation of EB, VL and RF, in co-contraction index BF-RF, BF-VL and EB-MU, as well as in perceived exertion sensation between Chair and Reformer apparatus during the legwork movement. This is probably due to differences in the ROM and recruiting strategies, once the imposed final external load was the same for both apparatus. This information should be considered in conditioning and rehabilitation program in Pilates. It‟s possible to conclude that there are differences between legwork exercise performed on Chair and Reformer apparatus in relation to EMG activity of specific muscles, ROM and related Borg perceived exertion scale.

Testo completoAbstract (sommario):
Aim: The aim of this study is to analyse potential determinants of cycle commuting speed, with the following research questions: 1. How does cycle commuting speed relate to amount of gears, access to shower facilities, and rating of perceived exertion (RPE), when sex, age, weight, body mass index (BMI), duration, last digit in self-reported duration, and cycling area are controlled for? 2. How are the earlier found relationships between speed and duration, and speed and sex, affected when amount of gears, access to shower facilities, and RPE are added to the control variables age, weight, BMI, last digit in self-reported duration, and cycling area? Method: In this cross-sectional study, 1526 adult cycle commuters (67% females) in Stockholm County, Sweden, were recruited through advertisements. In a self-administered questionnaire, the respondents reported their sex, age, height, weight, duration of their typical cycle commuting journey, amount of gears, access to shower facilities at the destination, and rating of perceived exertion (measured by the Borg RPE Scale) while cycling. They also drew their cycling route on an individually adjusted map. Multiple linear regression was used to facilitate the analyses. Results: In a regression model with the independent variables sex, age, weight, body mass index, duration, last digit in self-reported duration (1–4 or 6–9 compared to 0 or 5), cycling area (inner urban compared to suburban and suburban – inner urban), gears, shower facilities, and RPE, the dependent variable cycle commuting speed was positively related to using a bicycle with five or more (as compared to four or fewer) gears, having convenient (as opposed to inconvenient or non-existent) access to shower facilities, and perceiving a higher degree of exertion while cycling. Gears, showers, and RPE were also found to substantially affect the earlier found relationships between speed and duration, and speed and sex. The respondents showed a clear tendency of giving odd-numbered, compared to even-numbered, ratings of perceived exertion. Conclusions: This study highlights the importance of gears, showers, and RPE in activities such as estimating, planning or taking measures in relation to cycle commuting. It also shows that adding new factors to control for might change earlier established relationships within this field. When the Borg RPE Scale is used, correct instructions strengthens the validity.Syfte och frågeställningar: Syftet med denna studie är att analysera potentiella påverkansfaktorer gällande cykelpendlingshastighet, med följande frågeställningar: 1. Hur relaterar hastighet till antal växlar, tillgång till duschfaciliteter och skattning av egenupplevd fysisk ansträngningsgrad (RPE), när kön, ålder, vikt, BMI, duration, slutsiffra i självrapporterad duration samt cykelområde kontrolleras? 2. Hur påverkas de tidigare funna förhållandena mellan hastighet och duration, samt hastighet och kön, när antal växlar, tillgång till duschfaciliteter och RPE adderas till kontrollvariablerna ålder, vikt, BMI, slutsiffra i självrapporterad duration, och cykelområde? Metod: I denna tvärsnittsstudie rekryterades 1526 vuxna cykelpendlare (67% kvinnor) i Stockholms län genom annonser. I ett själv-administrerat formulär rapporterade de kön, ålder, längd, vikt, duration vid deras typiska cykelpendlingsresa, antal växlar, tillgång till duschfaciliteter vid destinationen, och skattning av egenupplevd fysisk ansträngningsgrad (enligt Borgskalan) under cyklingen. De ritade även in sin cykelväg på en individuellt anpassad karta. Multipel linjär regression användes för att möjliggöra analyserna. Resultat: I en regressionsmodell med de oberoende variablerna kön, ålder, vikt, BMI, duration, slutsiffra i självrapporterad duration (1–4 eller 6–9 jämfört med 0 eller 5), cykelområde (innerstad i jämförelse med ytterstad samt ytterstad – innerstad), växlar, duschmöjligheter och RPE, var den beroende variabeln cykelhastighet positivt relaterad till användandet av en cykel med fem växlar eller fler (i jämförelse med fyra eller färre), att ha bekväm tillgång till dusch (i motsats till obekväm eller ingen tillgång alls) samt att uppleva en högre grad av fysisk ansträngning under cykling. Växlar, duschmöjligheter och RPE visade sig även substantiellt påverka de tidigare funna förhållandena mellan hastighet och duration, samt hastighet och kön. Respondenterna visade en tydlig tendens att ge ojämna, i jämförelse med jämna, RPE-skattningar. Slutsats: Denna studie belyser vikten av växlar, duschmöjligheter och egenupplevd ansträngningsgrad vid exempelvis bedömning, planering eller vidtagande av åtgärder i relation till cykelpendling. Den visar även att nya kontrollfaktorer kan förändra tidigare etablerade förhållanden inom detta fält. Korrekta instruktioner stärker validiteten vid användandet av Borgskalan.

Testo completoAbstract (sommario):
An interesting aspect when studying the performance of physical work is the relationship between psychophysical and physiological growth functions as well as estimations of maximal capacity from sub-maximal levels. The current study compared the Borg CR10 and CR100 scales on physical work during a bicycle ergometer test with 24 test subjects, finding the CR100 scale slightly more detailed at lower levels of perceived exertion and containing a more natural nu-merical range. The CR100 scale was subsequently used to determine the psychophysical growth functions during cycling and power lifting. Obtained exponents were approx. 1.8 (chest) and 1.9 (legs) for cycling and 2.1; 2.2 for squats and bench press respectively. The data was used to estimate the maximal capacity of 17 subjects from sub-maximal levels, predicting one repetition max capacity within on av-erage 3 kg. Maximal aerobic capacity proved more problematic to es-timate, with obtained correlation coefficients of 0.38 (n.s.) - 0.65 (pd0.05) for running and cycling respectively (13 subjects).

Testo completoAbstract (sommario):
The Borg Rating of Perceived Exertion (RPE) scale is a primary tool for researchers and practitioners in exercise science to describe the intensity level subjects are experiencing when participating in exercise sessions. It has recently been suggested that RPE is not simply the direct result of interpretation of physiological changes as originally postulated, but is also influenced by affect, past experience, and time to completion, a concept coined as teleoanticipation.
The purpose of this study was to determine the role of teleoanticipation in a sedentary population, by examining the effect unexpected increases in exercise duration on rating of perceived exertion and affect during low intensity treadmill walking. Based on the findings of prior studies, it is expected that the unexpected duration session will elicit higher RPE values and lower affect scores as measured by the feeling scale (FS) than the expected duration session.
Ten participants between the ages of 18 and 45 years participated in the study. All participants were sedentary or insufficiently active with respect to physical activity for at least six months prior to the beginning of the study. Only participants with low to moderate risk according to the American College of Sports Medicine (ACSM) guidelines were admitted.
All volunteers participated in one familiarization session followed by two trials of treadmill exercise. The familiarization trial was used to determine the treadmill speed in subsequent trials. All experimental trials were 30 minutes in length in partial accordance with ACSM guidelines, but the third trial in each group was presented as being 20 minutes and was extended to 30 minutes using a deception procedure employed in related research. Participants were informed at the 20-minute mark that the session would be extended to 30 minutes. Speed remained constant during both experimental trials.
RPE and heart rate were recorded every minute to preclude volunteers from noticing the difference an increased interest in RPE responses around the 20-minute mark. Affect was measured by way of the feeling scale (FS) every other minute during the experimental trials. Blood pressure was recorded every five minutes to ensure participant safety.
Results indicated a significant main effect for time for RPE (p = 0.001); however, there was no significant main effect for time and no interaction for RPE (p > 0.05) and no significant main effect and no interaction for FS. The primary finding from this investigation was that unexpected exercise durations have no affect on RPE or FS at low intensities in untrained, sedentary populations. Results suggest there may be a threshold of intensity required for a teleoanticipatory effect. More research is needed to further compare these effects with those of moderately and highly trained populations in medium or high intensity situations.

Testo completoAbstract (sommario):
O objetivo do presente estudo foi verificar as relações entre a percepção de esforço (PE) e diferentes cargas em exercícios de força (EF), em sujeitos adultos sedentários, ativos e treinados. Trinta homens com idade entre 18 e 34 anos, foram divididos em três grupos experimentais (GE) de 10 sujeitos cada, sendo os mesmos classificados pelo seu histórico recente (12 meses) de prática de exercícios físicos: grupo de sedentários (GSE), grupo de treinados em força (GTF) e o grupo de fisicamente ativos (GAT). A avaliação da força máxima foi estabelecida através do teste de uma repetição máxima (1RM) nos EF supino (SUP) e pressão de pernas (PP). Através da realização de séries de 12 repetições, diferentes cargas foram aplicadas até que os 4 índices de esforço percebido (IEP – 11, 13, 15 e 17 da Escala RPE de Borg) fossem determinados. O ritmo foi controlado (3 segundos para cada repetição), as cargas foram ocultas, os intervalos controlados (3 a 5 minutos), a ordem dos IEP randomizados, a PE localizada e determinada após a realização da série. Após identificada a carga correspondente à cada IEP, a mesma foi relativizada em percentuais pelo teste de 1RM correspondente (%1RM). A análise estatísitica foi realizada através da análise de variância com bloqueamento e pela correlação de Spearman, sendo o nível de significância de p < 0,05, com os dados processados no software SPSS v. 13. Os resultados indicaram altas (r = 0,826 a 0,922) e significativas (p < 0,05) correlações entre os IEP e o %1RM, conforme GE e EF. Um comportamento similar foi encontrado entre os EF. Maiores cargas estão relacionadas com maiores IEP, sendo diferenciado entre os GE. O GTF utiliza um maior %1RM em relação ao GSE, enquanto que o GAT, apresentou um comportamento intermediário em relação aos demais grupos. Menor variabilidade das respostas do %1RM é verificada nos IEP maiores. Desta forma, acreditamos que a utilização da percepção de esforço pode ser um instrumento confiável na mensuração da intensidade do treinamento de força.The aim of this study was to verify the relationship between the perceived exertion (PE) and different intensity in strength exercise (SE), in sedentary, active and trained adults subjects. Thirty males with 18 and 34 years old, were matched in 3 experimental groups (EG) with 10 subjects in each group, classified for their recent description (12 months) of physical exercises activities: sedentary group (GSE), strength training group (GST) and the physically active group (GPA). The maximum strength was measured through the 1 repetition maximum test (1RM) on the bench press and leg press exercise. With the accomplishment of sets of 12 repetitions, different loads were applied until the 4 ratings of perceived exertion (Borg’s RPE Scale - 11, 13, 15 and 17 ratings) were determined. The rhythm was controlled (3 seconds for each repetition), the loads were blinded to subjects, the intervals were controlled (3 - 5 minutes), the order of the RPE and exercise were randomized, and the active muscular PE were assessed following each set. After determination of corresponding load to each RPE, it was related by percentages for the corresponding 1RM (%1RM). Statistical analysis was carried by analysis of variance with lock-in and for the correlation of Spearman, with significant level p < 0,05, processing wit SPSS v. 13 software. The results indicated high (r = 0,826 a 0,922) and significant (p < 0,05) correlation between RPE and %1RM, as EG and SE. Similar results were found between the SE. Higher loads are related with higher RPE, with different behavior between EG. The GST uses higher %1RM in relation to the GSE, while the GAT, presented an intermediate behavior related to the other groups. Lower variability of responses of %1RM is observed in higher RPE. Thus, we believe that utilization of perception exertion can be a trustworthy instrument in the measurements of intensity in strength training.

Purpose: The purpose of this study was to investigate the RPE value and the relationship of physiological responses in comparing Borg 6~20 scale and OMNI scale during the exhaustive exercise on bicycle ergometer. Methods: 30 healthy males students (age: 20.03 ± 2.22 years; height: 175.37 ± 4.57 cm; weight: 70.57 ± 7.33 kg; BMI: 22.91 ± 1.85 kg/m2) of the Department of Physical Education were tested in this study. Each testing subject used Borg 6~20 scale and OMNI scale respectively by counter-balance design, and did the testing of the exhaustive exercise on bicycle ergometer. Heart rate, ventilation, oxygen consumption, respiratory exchange rate, and RPE value of every subject during each stage were measured when exercising. Pearson’s correlation was applied to get the correlation between RPE value of two kinds of scales and physiological responses. Dependent t-test was applied to compare the correlation between two kinds of scales. Results: The RPE value of the two scales were significantly correlated with heart rate, ventilation, oxygen consumption and respiratory exchange rate ( p<.05). And the correlation coefficients were not significantly different between the two kinds of scales. Conclusion: The Borg 6~20 scale and OMNI scale are all good for identifying exercise intensity for adults during incremental exercise testing.

The main aims of this investigation were to determine whether facial expression could reflect the perception of effort, and then to develop and validate a pictorial exertion scale. The facial pictorial rating of perceived exertion (FPRPE) scale that focuses on the facial expression of effort was developed for evaluating physical tasks. The FPRPE scale has a category-rating format that contains both pictorial and verbal descriptors positioned along a comparatively narrow numerical response range, namely 0–10. A total of seven studies were conducted to develop the scale. The first study determined whether the facial expression of effort reflected the perception of effort. Studies two to four focused on the development and validation of the pictorial facial rating of perceived exertion (RPE) scale. Study five and six examined the correlations between subjective RPE and observational RPE by the FPRPE scale. Study seven was to determine a relationship between facial pictorial descriptor and exertion intensity. Studies one to four revealed that facial muscle activity reflects the perception of effort during incremental workload cycling. The FPRPE scale was developed based on the facial features of frowning and jaw clenching as pictorial representations of exertion. Both concurrent and construct validation supported the use of the FPRPE scale by male and female adults to estimate RPE during the incremental cycle ergometer test. Results of studies five to seven indicated that the observers would be able to apply facial expression to estimate the level of perceived exertion. The pictorial faces on the FPRPE scale suggested curvilinear increased as exertion intensity increased for observation of perceived exertion. The FPRPE scale is an alternative pictorial scale utilizing facial expression of exertion so participants can more easily estimate their internal level of exertion during exercise, and the scale will be useful for observation of exertion as well.

As the Borg rating of perceived exertion scale was not appropriate for children, investigators set about developing child-specific scales which employed numbers, words and/or images that were more familiar and understandable. Numerous studies have examined the validity and reliability of such scales as the CERT, PCERT and OMNI amongst children aged 5 to 16 years, across different modes of exercise (cycling, running, stepping, resistance exercise), protocols (intermittent vs. continuous, incremental vs. non-incremental) and paradigms (estimation vs. production). Such laboratory-based research has enabled the general conclusion that children can, especially with practise, use effort perception scales to differentiate between exercise intensity levels, and to self-regulate their exercise output to match various levels indicated by them. However, inconsistencies in the methodological approaches adopted diminish the certainty of some of the interpretations made by researchers. The scope for research in the application of effort perception in physical education and activity/health promotion is considerable.

The chapter The Ellestad Protocol reviews the performance of a maximal exercise test from start to finish using the Ellestad protocol as an example. Patient preparation should include caffeine avoidance should a vasodilator myocardial perfusion imaging (MPI) test be necessary secondary to inadequate exercise. A light meal prior to exercise testing is acceptable. The Bruce and Ellestad protocols both begin with a stage each investigator regarded as a warm-up, 3 minutes of exercise at 1.7 mph at a 10% grade. With two minute stages, primarily of increasing grade, the Ellestad protocol is completed approximately one minute earlier than the Bruce protocol. The use of the Borg scale of perceived exertion is helpful in determining a patient’s effort. If ancillary MPI is not being performed, an abrupt stop for a motion-free electrocardiogram (ECG) and then immediately placing the patient supine or semi-supine increases pre-load and, via the law of Laplace, increases left ventricular end-diastolic pressure, myocardial oxygen demand and thus ischemia. ST segment depression is observed earlier in recovery than if a cool-down walk is performed. Case examples are provided.
