Resumo: The purpose of this study was to investigate the physiological and perceptual responses of sedentary women while walking at a self-selected pace. The sample was made up of forty-one women with a median age of 32.6 ± 8.6 years. Subjects underwent an incremental test until exhaustion on a treadmill in order to determine their maximum physiological and perceptual responses. The subjects then a 20-minute walking test at their self-selected pace to determine physiological and perceptual responses. Descriptive analysis was in the form of measures of central tendency, variability and relative frequency. Mean exercise intensity during the walking bout was 57.3 ± 12.1% of peak oxygen consumption (VO2peak) and 74.4 ± 9.3% of peak heart rate (HRpeak), corresponding to 88.4 ± 19.8% and 85.6 ± 21.6% of the fi gures obtained at ventilatory threshold (VT), respectively. Nevertheless, the rating of perceived effort (RPE) and affective valence (AV) during the walking session returned mean values of 11.9 ± 2.1 and 2.4 ± 2.0, which correspond to 100.7 ± 20.0% and 96.0 ± 2.0% of the fi gures obtained at VT, respectively. In conclusion, the exercise intensity that was self-selected by this group of sedentary women meets current recommendations for moderate intensity exercise and was associated with increased pleasure.

Foram investigados 41 sujeitos (idade 32,6 ± 8,6 anos), os quais realizaram, inicialmente, um teste de esteira incremental até a exaustão para a determinação de respostas fi siológicas e perceptivas máximas e, posteriormente, um teste de caminhada em esteira por 20 minutos em uma intensidade auto-selecionada, no qual parâmetros fi siológicos e perceptivos foram obtidos. Medidas de tendência central e variabilidade foram empregadas para a análise descritiva das variáveis investigadas nesse estudo. Em relação às respostas fi siológicas, verifi cou-se que os sujeitos preferem exercitar-se em uma intensidade média de 57,3 ± 12,1% do consumo de oxigênio pico (VO2pico) e 74,4 ± 9,3% da frequência cardíaca pico (FCpico), correspondente à 88,4 ± 19,8% e 85,6 ± 21,6% dos valores obtidos no limiar ventilatório (LV). Por sua vez, as respostas perceptivas de sensação subjetiva de esforço (SSE) e valência afetiva (VA) determinadas durante a caminhada, apresentaram valores médios de 11.9 ± 2,1 e 2,4 ± 2,0, equivalentes a 100,7 ± 20,0% e 96,0 ± 2,0% dos valores de LV, respectivamente. Desse modo, pode-se concluir que mulheres adultas previamente sedentárias auto-selecionam uma intensidade de caminhada perceptivamente agradável e capaz de proporcionar a ocorrência de signifi cativas adaptações cardiorrespiratórias.Universidade Federal de Santa Catarina.
