Little is known about the influence of body adiposity and the acute response of the cardiovascular system during whole the 6-minute walk test (6mWT). Objective: To evaluate the effect of anthropometric measures (BMI and WHR waist-to-hip ratio), the effort heart and inactivity in ability to walk the morbidly obese. Materials and Methods: a total 36 morbidly obese (36.23 + 11.82 years old, BMI 49.16 kg/m2) were recruited from outpatient department of treatment of obesity and bariatric surgery in University Hospital Onofre Lopes and anthropometric measurements of obesity (BMI and WHR), pulmonary function, pattern habitual physical activity (Baecke Questionnaire) and walking capacity (6mWT). The patient was checking to measure: heart rate (HR), breathing frequency (BF), peripheral oxygen saturation, level of perceived exertion, systemic arterial pressure and duplo-produto (DP), moreover the average speed development and total distance walking. The data were analysed between gender and pattern of body adiposity, measuring the behavior minute by minute of walking. The Pearson and Spearmam correlation coefficients were calculated, and stepwise multiple Regression examined the predictors of walking capacity. All analyses were performed en software Statistic 6.0. Results: 20 obese patients had abdominal adiposity (WHR = 1.01), waist circumference was 135.8 cm in women (25) and 139.8 cm in men (10). Walked to the end of 6mWT 412.43 m, with no differences between gender and adiposity. The total distance walked by obesity alone was explained by BMI (45%), HR in the sixth minute (43%), the Baecke (24%) and fatigue (-23%). 88.6% of obese (31) performed the test above 60% of maximal HR, while the peak HR achieved at 5-minute of 6mWT. Systemic arterial pressure and DP rised after walking, but with no differences between gender and adiposity. Conclusion: The walk of obese didn?t suffers influence of gender or the pattern of body adiposity. The final distance walked is attributed to excess body weight, stress heart, the feeling of effort required by physical activity and level of sedentary to obese. With a minute of walking, the obeses achieved a range of intensity cardiovascular trainning / Introdu??o: A capacidade de caminhar dos obesos ? prejudicada pelo ?ndice de Massa Corporal (IMC), dores osteomioarticulares e n?vel de sedentarismo. Pouco se sabe sobre a influ?ncia do perfil da adiposidade corporal, do g?nero e da resposta aguda do sistema cardiovascular sobre a capacidade de caminhada do obeso. Objetivo: Avaliar o efeito de medidas antropom?tricas (IMC e WHR, waist-to-hip ratio), esfor?o card?aco e sedentarismo sobre a capacidade de caminhada de portadores de obesidade m?rbida. Materiais e M?todos: Entre setembro de 2007 e setembro de 2008, 36 obesos m?rbidos (idade 36,23 + 11,82; IMC 49,16 kg/m2) foram recrutados no ambulat?rio de tratamento da obesidade e cirurgia bari?trica do Hospital Universit?rio Onofre Lopes e avaliados quanto marcadores antropom?tricos de obesidade, fun??o pulmonar, n?vel de atividade f?sica habitual (Question?rio de Baecke) e capacidade de caminhar (TC6M). O paciente era monitorado para verificar: freq??ncia card?aca (FC) e respirat?ria (FR), satura??o perif?rica de oxig?nio, n?vel de esfor?o percebido, press?o arterial sist?mica (PA) e duplo-produto (DP). Durante a caminhada, ainda mensurava-se a velocidade m?dia desenvolvida e dist?ncia total percorrida pelos portadores de obesidade m?rbida. Os dados foram analisados entre os g?neros e o tipo de distribui??o de gordura corporal, avaliando o comportamento das vari?veis a cada minuto caminhado. As correla??es de Pearson e Spearmam foram analisadas. A Regress?o M?ltipla buscou preditores da capacidade de caminhada. Foi utilizado o software Statistic 6.0 para an?lise estat?stica. Resultados: 20 obesos tinham adiposidade abdominal (WHR = 1,01), circunfer?ncia da cintura de 135,8 cm nas mulheres (25) e de 139,8 cm nos homens (10). Durante TC6M, foi caminhada uma dist?ncia de 412,43 m, sem diferen?as entre g?nero ou adiposidade. Essa dist?ncia total percorrida foi explicada isoladamente pelo IMC (45%), FC no sexto minuto (43%), Baecke (24%) e fadiga (-23%). 88,6% dos obesos (31) realizaram o teste acima de 60% da FCM?xima, sendo o pico de FC atingido aos 5 minutos de caminhada. PA e DP aumentaram significativamente com a caminhada, mas sem diferen?as entre g?nero ou adiposidade. Conclus?o: A acaminhada dos obesos m?rbidos n?o sofre influ?ncia do g?nero ou do perfil de adiposidade corporal. A dist?ncia final percorrida ? atribu?da ao excesso de peso corporal, estress card?aco, sensa??o de esfor?o imposta pela caminhada e ao n?vel de sedentarismo pr?vio do obeso. Dentro de 1 minuto de caminhada, os obesos atingem uma zona de treinamento cardiovascular
