The purpose of this study was to compare the physiological adaptations to basic head-out aquatic exercises with different levels of body immersion. Sixteen young and clinically healthy subjects (9 women and 7 men) volunteered to participate in this study. Each subject performed 3 repetitions (on land, immersed to the hip, and immersed to the breast) of the aquatic exercise ‘‘rocking horse’’ for 6 minutes. The rating of perceived effort (RPE), the maximal heart rate achieved during the exercitation (HRmax), the percentage of the maximal theoretical heart rate estimated (%HRmax), the peak of oxygen uptake during the exercise (V˙ O2peak), and the energy expenditure (EE) were evaluated. The RPE was significantly higher when exercising immersed to the hip than on land ( p 0.01) and immersed to the breast ( p 0.03). The HRmax and %HRmax were significantly lower when exercising with immersion to the breast than on land ( p 0.01) and with immersion to the hip ( p 0.01). The V˙ O2peak was significantly different between all conditions. The lower mean value was verified when exercising immersed to the breast, followed by immersion to the hip and on land. The EE was significantly higher when performing aquatic exercises on land than when immersed to the hip ( p 0.02) and the breast ( p 0.01). So...

A presente dissertação é constituida de duas partes. A primeira parte teve como objetivo determinar o perfil antropométrico e o consumo alimentar de atletas de Tênis profissionais e amadores. Foram avaliados parâmetros antropométricos (massa corporal, altura, circunferências e dobras cutâneas) e o consumo alimentar pelo diário alimentar de 3 dias. Não foi observada diferença significativa no perfil antropométrico de atletas amadores e profissionais. Com relação ao consumo alimentar, ambos os grupos demonstraram baixa ingestão de carboidrato (CHO) (AM: 6,3±0,5 g/kg/dia e PRO: 6,5±0,7 g/kg/dia) quando comparada às recomendações atuais disponíveis na literatura. Estes dados reforçam a importância do planejamento nutricional para estes atletas. Na segunda parte, foi avaliado o efeito da suplementação de CHO sobre a percepção subjetiva de esforço (PSE), a resposta hormonal, a concentração de IgA salivar e o desempenho durante uma partida de Tênis com duração de 180 minutos. A PSE apresentou aumento no decorrer da partida, porém não foi detectada diferença entre as condições experimentais - placebo (PLA) e CHO (P>0,05). Com relação a PSE da sessão, a ingestão de CHO parece promover tendência de redução (P=0...

O objetivo do estudo foi examinar a influência de variáveis fisiológicas, perceptuais e mecânicas nas diferentes estratégias de corrida e no desempenho de atletas. Doze corredores especialistas em 5.000m realizaram: 1) um teste escalonado máximo para identificação do consumo máximo de oxigênio (VO2máx), velocidade de corrida associada ao VO2máx (vVO2máx), pico de velocidade em esteira (PVE) e velocidade de corrida associada ao limiar anaeróbio (vLAn); 2) uma prova de corrida de 5.000m avaliada a cada trecho (n = 5) de 1.000m em pista de atletismo para registro da frequência cardíaca (FC), percepção subjetiva de esforço (PSE) e velocidade de corrida. Os sujeitos foram divididos em dois grupos: saída lenta (SL) e saída rápida (SR) de acordo com a estratégia adotada, que por sua vez foi baseada na relação da velocidade de corrida no trecho inicial (Vel20%) com a velocidade média do teste de 5.000m. Os dados foram comparados entre os grupos de estratégia e posteriormente entre os trechos da prova esportiva para cada variável analisada. A velocidade de corrida no trecho inicial (SL = 16,9km.h-1 e SR = 19,1km.h-1) e no trecho final (SL = 19,1km.h-1 e SR = 16,7km.h-1) foi significantemente diferente (p < 0,05)...

Estratégia de corrida é forma pela qual os corredores distribuem a velocidade durante uma competição. Objetivando otimizar a utilização dos recursos energéticos, bem como melhorar o desempenho geral na prova, durante uma corrida de 5 km os atletas comumente adotam uma estratégia caracterizada por um início em alta velocidade, seguido por um trecho intermediário em velocidade inferior, e finalmente os atletas aumentam a velocidade quando se aproximam dos 400 m finais da prova. Sabe-se que o treinamento intervalado de alta intensidade (TIAI) realizado ao longo de 3 a 6 semanas é capaz de promover melhoras significativas nas variáveis fisiológicas determinantes do desempenho aeróbio, tais como VO2max, EC, VP, e OBLA. Uma vez que os atletas monitoram a PSE baseado em sinais internos (fisiológicos) e externos (ambiente), e desta forma alteram a velocidade para evitarem o término prematuro do exercício, acredita-se que melhoras em tais variáveis fisiológicas possam permitir que os corredores modifiquem a estratégia de corrida. Portanto, o principal objetivo do presente estudo foi analisar a influência de quatro semanas de TIAI sobre a PSE e também sobre a estratégia de corrida adotada por corredores durante um teste contra-relógio de 5 km (T5). Vinte sujeitos...

The hereditary ataxias comprise a very large spectrum of genetically determined neurodegenerative disorders with progressive ataxia as the prominent symptom. In order to measure the severity of cerebellar ataxia in an easier and more practical way, it was proposed a new scale: the Scale for the Assessment and Rating of Ataxia (SARA). The objective of this study was to translate and validate SARA into Brazilian Portuguese. METHOD: The SARA was translated into Brazilian Portuguese, analyzed, back translated to English, and compared to the original version. It was applied to 30 patients. In addition to SARA, we applied the International Cooperative Ataxia Rating Scale (ICARS) in all subjects. RESULTS: SARA scale was translated into Brazilian version with adequate internal consistence, but a significant correlation between ICARS and SARA was not found. CONCLUSION: SARA was translated and validated into Brazilian Portuguese language, showing good reliability and validity.

The aim of this study was to compare total work volume, number of repetitions and rate of perceived effort performed in two different sequences of circuit training sessions. Eleven recreationally trained men (24.0 ± 4.8 years, 76.1 ± 8.5 kg, 1.75 ± 0.06 m) performed two different sequences of circuit training sessions. All sessions consisted of eight stations (exercises) of three sets in circuit, performed to volitional fatigue, alternating upper and lower body exercises, with 1-minute rest interval between exercises. Sequence A began with multiple joint exercises and progressed to single joint exercises, whereas sequence B was performed with the opposite exercise order. Number of repetitions and rating of perceived exertion (RPE) were compared by repeated measures multivariate analysis of variance (repeated measures MANOVA). Total work volume (TWV) was compared by paired t-test. There were no differences between exercise order for TWV (p=0.47) and RPE of all exercises (p>0.05). For both sequences, number of repetitions was greater when exercise was performed first (p<0.05). These results indicate that during a circuit training session, exercises order influenced the number of repetition, but did not influence TWV and RPE. These findings may suggest that for those who aim overall muscular gains...

Most clinicians ask their patients to rate whether their health condition has improved or deteriorated over time and then use this information to guide management decisions. Many studies also use patient-rated change as an outcome measure to determine the efficacy of a particular treatment. Global rating of change (GRC) scales provide a method of obtaining this information in a manner that is quick, flexible, and efficient. As with any outcome measure, however, meaningful interpretation of results can only be undertaken with due consideration of the clinimetric properties, strengths, and weaknesses of the instrument. The purpose of this article is to summarize this information to assist appropriate interpretation of the GRC results and to provide evidence-informed advice to guide design and administration of GRC scales. These considerations are relevant and applicable to the use of GRC scales both in the clinic and in research.

The aim of the present study was to analyse the usefulness of the 6-20 rating of perceived exertion (RPE) scale for prescribing and self-regulating high-intensity interval training (HIT) in young individuals. Eight healthy young subjects (age = 27.5±6.7 years) performed maximal graded exercise testing to determine their maximal and reserve heart rate (HR). Subjects then performed two HIT sessions (20 min on a treadmill) prescribed and regulated by their HR (HR: 1 min at 50% alternated with 1 min at 85% of reserve HR) or RPE (RPE: 1 minute at the 9-11 level [very light-fairly light] alternated with 1 minute at the 15-17 level [hard-very hard]) in random order. HR response and walking/running speed during the 20 min of exercise were compared between sessions. No significant difference between sessions was observed in HR during low- (HR: 135±15 bpm; RPE: 138±20 bpm) and high-intensity intervals (HR: 168±15 bpm; RPE: 170±18 bpm). Walking/running speed during low- (HR: 5.7±1.2 km · h−1; RPE: 5.7±1.3 km · h−1) and high-intensity intervals (HR: 7.8±1.9 km · h−1; RPE: 8.2±1.7 km · h−1) was also not different between sessions. No significant differences were observed in HR response and walking/running speed between HIT sessions prescribed and regulated by HR or RPE. This finding suggests that the 6-20 RPE scale may be a useful tool for prescribing and self-regulating HIT in young subjects.

Sustained carrying could result in muscular fatigue of the upper limb. Ten male and ten female subjects were recruited for measurements of isometric arm strength before and during carrying a load for a period of 4 minutes. Two levels of load of carrying were tested for each of the male and female subjects. Exponential function based predictive equations for the isometric arm strength were established. The mean absolute deviations of these models in predicting the isometric arm strength were in the range of 3.24 to 17.34 N. Regression analyses between the subjective ratings of upper limb fatigue and force change index (FCI) for the carrying were also performed. The results indicated that the subjective rating of muscular fatigue may be estimated by multiplying the FCI with a constant. The FCI may, therefore, be adopted as an index to assess muscular fatigue for two-handed carrying tasks.

RESUMEN: El principal objetivo de este trabajo ha sido el análisis de la fatiga en 15 jugadores de balonmano durante 3 semanas con 4 entrenamientos semanales para conocer su evolución y la capacidad de recuperación de los deportistas, y la relación entre medidas subjetivas y objetivas de fatiga. Para ello hemos utilizado tres herramientas, para analizar la fatiga objetiva se ha utilizado un single hop for distance, realizado por los deportistas antes y después de cada sesión, por otro lado, para conocer la fatiga subjetiva de los deportistas se ha incluido la escala de Hooper previa al entrenamiento y para medir la intensidad de la sesión se ha utilizado la escala de percepción subjetiva del esfuerzo. Se ha observado una relación directa entre la valoración subjetiva de la intensidad del entrenamiento tanto con los resultados objetivos de fatiga en el hop test (dominante (r=0.480; p˂0.01) y no dominante (r=0.465; p˂0.01).) como con la escala de Hooper previa al entrenamiento (r=0.644; p˂0.01). En cuanto a la fatiga objetiva analizada se ha hallado una correlación significativa entre ambas extremidades (r=0.835; p˂0.01). Respecto a las diferencias entre sesiones, únicamente se ha encontrado una diferencia significativa (F=3.287;p˂0.05) en la segunda semana respecto al resto de sesiones de la misma en el caso de la fatiga objetiva...

This research studies the success of Hispanic midshipmen at the Naval Academy. Specifically, graduation, senior leadership positions during first class (senior) year, military performance grades, and cumulative academic Quality Point Rating (college GPA) are examined as the measures of success. A host of pre entry variables are used to control any affect they might have that would otherwise be confounded with midshipmen's ethnic, racial, or gender identification. Midshipmen from the classes of 1999 to 2004 compose the dataset for regression analysis. Hispanic midshipmen cannot be studied in a vacuum, and therefore, this research generates information on a number of different groups. But, the performance of Hispanic midshipmen at the Naval Academy is of primary focus throughout. Of the four measures of success, this study shows that Hispanic midshipmen are likely to have a lower cumulative academic QPR; but, are proportionately represented in terms of graduation, senior leadership positions, and military performance grades.

The study focused on the teacher as an adult learner rather than an instructor. A sample of three hundred and three elementary school teachers completed a two-part Likert survey questionnaire. The instrument was developed by the researcher in an attempt to operationalize Mezirow's Theory of Perspective Transformation. The four sub-scales collected information about teachers as they perceived themselves as adult learners and the way they conceptualize critical SelfReflection, Meaning perspectives and New Insights (Mezirow, 1978, 1981, 1989, 1990) within a framework of Mezirow's concept of Transformative Learning. Survey research methodology was used. Frequency distributions, means, and standard deviation were calculated. Reliability analysis and Pearson 'r' correlations established the internal consistency of items It Cross tabulations to describe differences in responses across demographic valuables were computed. The survey results indicated that teachers perceived themselves as self-directed learners. The findings support the need for a better understanding of the teacher as an adult learner so that teacher inservice programs and teacher supervision and evaluation can provide a viable learning alternative to the existing models used in practice.

Purpose: The aim of this study was to verify the influence of aerobic fitness (VO(2)max) on internal training loads, as measured by the session rating of perceived exertion (session-RPE) method. Methods: Nine male professional outfield futsal players were monitored for 4 wk of the in-season period with regards to the weekly accumulated session-RPE, while participating in the same training sessions. Single-session-RPE was obtained from the product of a 10-point RPE scale and the duration of exercise. Maximal oxygen consumption was determined during an incremental treadmill test. Results: The average training load throughout the 4 wk period varied between 2,876 and 5,035 arbitrary units. Technical-tactical sessions were the predominant source of loading. There was a significant correlation between VO(2)max (59.6 +/- 2.5 mL.kg(-1).min(-1)) and overall training load accumulated over the total period (r = -0.75). Conclusions: The VO(2)max plays a key role in determining the magnitude of an individual's perceived exertion during futsal training sessions.

O objetivo deste estudo foi analisar o comportamento de variáveis fisiológicas e do Índice de Percepção de Esforço (IPE) durante os diferentes momentos da aula de hidroginástica. Foram estudadas 17 mulheres, universitárias (idade 23,06±2,05 anos) investigadas em duas etapas: 1) teste de esforço máximo na esteira (VO2pico e FCmáx); e 2) avaliação da composição corporal e realização da aula de hidroginástica (FC, VO2, [lac] e IPE). Utilizaram-se a estatística descritiva e ANOVA medidas repetidas, com o teste post hoc Student-Newman-Keuls (p< 0,05). Os resultados mostraram que tanto a FC, quanto o VO2 apresentaram valores estatisticamente diferentes (p=0,000) nos três períodos da aula. Os valores de lactato sanguíneo apresentaram-se diferentes estatisticamente (p=0,001), somente quando foram comparados os valores obtidos no período inicial (1,55 mM) e principal (3,58 mM). O IPE médio foi de 11 e o gasto calórico total foi de 262,10 kcal. Conclui-se que as variáveis fisiológicas estudadas e o IPE apresentam uma variação significativa em função das três fases da aula de hidroginástica. Além disso, as intensidades de esforço (FC, VO2, [lac]) obtidas no período principal estão dentro dos padrões estabelecidos pela literatura para exercícios aeróbios. Dessa forma...

The objective of this study was to report and analyze the internal training load in a macrocycle of futsal using the session rating of perceived exer­tion (session-RPE) method. The sample consisted of 13 athletes of the National League. We calculated the total weekly training load (TWTL), monotony and strain over 37 weeks. Using the paired Student’s t Test, the preparation period (PP) showed higher TWTL, strain and monotony than the competitive period (CP). The ANOVA test of repeated measures, followed by the Bonferroni post-hoc test showed significant differences in the TWTL among the mesocycles: 1 > 2, 4, 5, 6, 8, 9; 7 > 4, 5, 8, 9; 2, 3 and 6 > 5, 8, 9; 4 > 5; 8 > 5 (p<0.05). The training loads (TL) were higher in the PP with reduction in the CP, with cycles of high load being required during the CP.

http://dx.doi.org/10.5007/1980-0037.2009v11n4p435The objective of this study was to determine the acute effect of passive rest intervals and static stretching between resistance exercise sets on the number of maximal repetitions (RM), rating of perceived exertion (RPE), and cumulative number of repetitions in multiple sets with a workload adjusted by the 8RM test. Fourteen trained male subjects (24.4 ± 2.1 years; 79.1 ± 7.1 kg; 175.4 ± 5.6 cm) were studied. On the first two visits, the subjects were submitted to the test and 8RM re-test using chest press (CP) and squat (SQ) exercises. On the two subsequent visits, all subjects were randomly assigned to two experimental situations: a) 8RM test with a passive rest interval (PI); b) 8RM test with static stretching (SS). The subjects performed three sets of CP and SQ, intercalated with 2 minutes of passive rest or 30 seconds of static stretching. ANOVA revealed a significant decrease (p < 0.05) in the second (PI = 6 ± 0.8 x SS = 5.2 ± 1.0 repetitions) and third (PI = 4.1 ± 0.8 X SS = 3.3 ± 0.6 repetitions) sets for CP and only in the third set (PI = 4.9 ± 0.8 X SS = 4.2 ± 1.0 repetitions) for SQ. For RPE, the Wilcoxon test showed significant differences (p < 0.05) between all sets for CP and SQ. For the cumulative number of repetitions...

Sequence A began with multiple joint exercises and progressed to single joint exercises, whereas sequence B was performed with the opposite exercise order. Number of repetitions and rating of perceived exertion (RPE) were compared by repeated measures multivariate analysis of variance (repeated measures MANOVA). Total work volume (TWV) was compared by paired t-test. There were no differences between exercise order for TWV (p=0.47) and RPE of all exercises (p>0.05). For both sequences, number of repetitions was greater when exercise was performed first (p<0.05). These results indicate that during a circuit training session, exercises order influenced the number of repetition...
