Sixteen patients with COPD (GOLD I) with mild and moderate (GOLD II) severity aged 51 - 80 years old who visited at the outpatient examination room, Phramongkutklao Hospital divided into 2 groups; diaphragmatic breathing group (DB; n=8) and Farinelli's breathing group (FB; n=8). Participants in each group were administered to complete breathing exercise 5 times per week for 8 weeks. Physiological data and pulmonary function (FVC, FEV1, PEF, FEV1/FVC, FEF25-75%, MVV, VC, TV, IRV, ERV and IC), respiratory muscle strength (MIP and MEP), aerobic capacity (6-MWD and VO2max), impact of COPD questionnaire (mMRC and CAT), cytokine (TNF-α and IL-6), and oxidative stress (MDA) were analyzed during Pre- and Post-test.
This study was to investigate the effect of Farinelli's breathing exercise on pulmonary function, respiratory muscle strength, aerobic capacity, impact of COPD questionnaires, cytokines, and oxidative stress in patients with Chronic Obstructive Pulmonary Disease (COPD).
