Análise da Força, Qualidade de Vida e Tolerância ao Exercício na Doença Pulmonar Crônica

Abstract

The present study had the objective of analyzing the use of the strength test (1RM) in patients with Chronic Obstructive Pulmonary Disease (COPD) and correlating to functional capacity and quality of life in a pulmonary rehabilitation program (PRP). This retrospective cohort type observational study of correlation with consecutive sample in patients with COPD pre e post PRP, using the following tools: the 1RM test, the six minute walk test (6'MW), and the Saint George's Respiratory Questionnaire (QQVSG). The initial hypothesis was that there was a correlation between the 1 RM test and the 6´MW test and the QQVSG. 112 patients of both genders were included, 61.6% male and 38.39% female with an average age of 64.23 ± 8.74 years, with VEF1 (42.96 ± 19.02% of predicted). The 1RM tests with the greatest load increase were: pulldown (36.61±10.61 vs. 47.25±15.47; ∆=10.64kg), leg extension (33.91±11.51 vs. 44.57±14.98; ∆=10.66kg), and Bench Press (38.5±13.53 vs. 48.74±15.68; ∆=10.24kg), these differences were statistically significant. In the 6'MW, the pre and post PRP means were, respectively, 399.98 ± 98.37m vs. 453.42± 93.25m ∆=53.44 meters. Regarding quality of life we obtained the following results in the domains of the QQVSG: pre and post symptoms (48.38 ±20.21 vs. 33.48 ± 18.12; ∆=14.9), Activity (67.42 ± 21.88 vs. 52.11 ± 21.11; ∆=15.31), Impact (34.94 ± 17.39 vs. 21.98 ± 18.99; ∆=12.96), and Total (47.76 ± 15.74 vs. 32.67 ± 16.13; ∆=15.09). Regarding correlation, it was only obtained in the abdominal exercise with the QQVSG (r = 0.226 p = 0.017), in the other variables there was no correlation. It can be observed that the assessment and evolution of the program of physical exercises with the 1RM test was effective in the pulmonary rehabilitation program, associating with the results obtained in the QQVSG and 6'MW respectively.
