Physical Capacity of Patients With Chronic Obstructive Pulmonary Disease With and Without Supplementation of Whey

A randomized clinical study will be carried out with 62 patients (31 patients per group) with chronic obstructive pulmonary disease who came from specialized departments of the Pulmonology Service of the Hospital de Clínicas of Porto Alegre and were referred to the pulmonary rehabilitation program of this institution. Patients will be evaluated in relation to anthropometry, body composition, blood biochemistry, phase angle, dietary intake, physical capacity, muscle strength and lung function. The data will be processed in the statistical program SPSS version 17.0 and for statistical analysis they will be tested for their normality by the Kolmogorov-Smirnoff test and after this definition will be applied specific tests for parametric or non-parametric data, being they presented in the form of mean and standard deviation or median, minimum and maximum, according to their distribution. The differences will be considered significant for values of p \<0.05.
