Abstract

PURPOSE:  To do a prospective analysis between indirect methods of the corporal composition assessment and respiratory muscle strength and endurance in chronic Obstructive Pulmonary Disease (COPD) patients.

METHODS:  COPD patients in clinically stable condition were recruited, and for the control group normal subjects around the same age and biotype. All the subjects and patients were submitted to pulmonary function test (spirometry), maximal respiratory pressures (PImax and Pemax), respiratory muscles incremental endurance test, six-minute walk test (6MWT), skinfold and body mass index (BMI) measurements.

RESULTS:  A total of 30 subjects completed the study, 6 women and 24 men. They were divided between three different groups: Group A; moderate to severe COPD (n=11); Group B, mild COPD (n=10) and Group C, control group (n=9). The mean age was ( 69,54 ± 10,51years), ( 71,1 ± 8,13 years), ( 70,11 ± 5,86 years) and the mean values for the BMI was ( 24,00 ± 3,66 Kg/m2), ( 24,41 ± 0,58 Kg/m2) and (27,44 ± 1,33 Kg/m2) respectively . The results showed that the correlations were not statistically significant between the anthropometric variables measured and the strength and endurance of the respiratory muscles.

CONCLUSION:  It is a literature consensus that diminish nutritional state evidenced through the weight loss causes an impairment of the peripheral and the respiratory muscles. Our study did not showed correlations statistically significant between the nutritional variables and the strength and endurance of the respiratory muscles. Other studies are necessary with a bigger sample and with subjects with different degrees of nutritional impairment to have a better analysis of the correlation between the nutritional state and the respiratory muscles of the COPD patients.

CLINICAL IMPLICATIONS:  There is no correlation between indirect methods of the corporal composition assessment and muscle respiratory strength and endurance in copd patients with body mass index lower than 20 Kg/m2.
