Abstract

PURPOSE:  The objective of this study was to correlate the respiratory muscles strengh(RMS) and respiratory muscles incremental test (RMIT)with six minutes walk distance (6MWD)in COPD patients.

METHODS:  COPD patients in clinically stable condition between 59 and 80 years of age were selected if they met following criteria: mild to severe airflow obstruction according to Global Initiative for Chronic Obstructive Lung Disease. All patients were submited to lung function test, respiratory muscles strength, assessed by maximal inspiratory mouth pressure and maximal expiratory mouth pressure (PImax and PEmax), respiratory muscles incremental test (RMIT) and 6MWT.

RESULTS:  21 patients were studied (3 women and 18 mens). The mean age was 71,66± 14,78 years. The results showed the positive correlation between Inspiratory endurance time assessed by RMIT and 6MWD (r = +0,607 P= 0,004), maximal inspiratory and expiratory load evaluated through RMIT with 6MWD (r = +0,0598 P = 0,004) and (r = +0,442 P = 0,004)respectively. PImax and PEmax were not statistically significant.

CONCLUSION:  The results of the present study demonstrate a moderate and positive correlation between respiratory muscles incremental test and six minutes walk distance.

CLINICAL IMPLICATIONS:  The respiratory muscles endurance training might contribute to exercise performance evaluated by six minutes walk distance in patients with chronic airflow limitation.
