Impacto do exercício físico combinado na percepção do estado de saúde da pessoa com doença pulmonar obstrutiva crónica Impact of combined exercise on chronic obstructive pulmonary patients’ state of health
Abstract
Objectivo: O objectivo do estudo consistiu em avaliar a eficácia de um programa de treino combinado (exercícios aeróbios e exercícios de força muscular dinâmica) comparativamente com um programa de treino aeróbio, e de fisioterapia respiratória, ao nível do estado de saúde de indivíduos com DPOC, durante 10 semanas. Métodos: Cinquenta indivíduos com DPOC moderada e grave foram distribuídos aleatoriamente por dois grupos. Grupo CG (n=25) submetido a treino combinado, grupo AG (n=25) submetido a treino aeróbio, os quais foram comparados com cinquenta indivíduos com DPOC, que realizaram exercícios de reeducação respiratória e técnicas de desobstrução brônquica, grupo FR (n=50). Foi avaliado o estado de saúde através de Questionário do Hospital St.George na Doença Respiratória (SGRQ) e do Questionário SF-36 no início da intervenção e 10 semanas após. Resultados: O grupo CG apresentou diferenças (pAim: The aim of the study was to evaluate the effectiveness of a 10-week combined training programme (aerobic and strength exercise) compared to an aerobic training programme, and respiratory physiotherapy on COPD patients’ health. Methods: Fifty subjects with moderate to severe COPD were randomly assigned to two groups. Combined group (CG, n=25) who underwent combined training, and aerobic group (AG, n=25) who underwent aerobic training. These were compared with fifty COPD subjects who underwent respiratory physiotherapy, breathing control and bronchial clearance techniques (RP group, n = 50). We evaluated health state through two questionnaires, St.George’s Respiratory Questionnaire (SGRQ) and SF-36, at the beginning and at the end of the programme. Results: The CG group showed differences (p<0.0001) in modification rates in state of health compared to the AG and RP groups in the activity (64 ± 9%, 19 ± 7%, 1 ± 15%) , impact (35 ± 5%, 20 ± 18%, 1 ± 14%) and total (41 ± 9%, 26 ± 17%, 1 ± 15%) domains assessed by the SGRQ, and the physical function (109 ± 74%, 22 ± 12%, 0.1 ± 18%), physical role (52 ± 36%, 11 ± 15%, 1.3 ± 21%) and vitality (83 ± 39%, 14 ± 38%) domains assessed by SF-36. Conclusion: These results suggest that combined training in subjects with COPD appears to be a more effective method, with better clinical changes, and improvements in health state perception.
