Summary

The study will evaluate the effect of positive airway expiratory pressure (EPAP) on patients with chronic obstructive pulmonary disease (COPD) during submaximal upper limb exercise.

Conditions

  • Pulmonary Disease, Chronic Obstructive

Interventions

DIAGNOSTIC_TEST

Endurance test for upper limbs

Subjects will initially perform maximal incremental cardiopulmnar test of upper limbs to assess the suggestion of dynamic hyperinflation (DH). After that, it will be randomized, for those who presented DH, to perform the endurance test with and without the use of positive expiratory pressure mask.

DIAGNOSTIC_TEST

Functional test

The 6-min pegboard and ring test (6PBRT) will be performed under usual breathing and during application of the EPAP mask. In this condition will be evaluated the presence of dynamic hyperinflation, perception of effort and dipnea, in addition to exercise capacity.
