O objetivo deste estudo foi avaliar a eficácia de um protocolo de recondicionamento aeróbico para a melhora da capacidade funcional e dispnéia de pacientes pneumopatas crônicos, tendo como referência o teste de caminhada de 6 minutos (6MWD) para determinação da carga de treinamento. Metodologia: foram selecionados 10 pacientes pneumopatas crônicos (9 M e 1 F) com média de idade de 61,5 ± 10,6 anos, apresentando estabilidade clínica e sem contra-indicações para a prática de exercício aeróbico. O protocolo foi realizado em esteira ergométrica, com freqüência semanal de 3 sessões, durante 8 semanas. A velocidade de caminhada na esteira foi estipulada em 85% da velocidade média obtida no 6MWD. A capacidade funcional e a dispnéia foram avaliadas no inicio e ao término do treinamento. Para análise estatística foram utilizados os testes t-pareado e Wilcoxon, conforme as características das variáveis. As diferenças foram consideradas estatisticamente significativas quando p < 0,05. Resultados: Foi observada melhora da capacidade funcional através de aumento da distância percorrida no 6MWD (média = 445,7 ± 175 m vs 565,8 ± 174 m; p < 0,01) assim como redução da dispnéia pela MMRC [mediana = 3 (2 – 4) vs 1 (0 - 3); p < 0,05]. Conclusão: A velocidade média do 6MWD é um parâmetro eficaz para determinação da carga de treinamento em programas de recondicionamento aeróbico para pacientes pneumopatas crônicos.
