MECHANISMS BY WHICH EXERCISE TRAINING BENEFITS PATIENTS WITH COPD MECANISMOS PELO QUAL O TREINAMENTO DE EXERCÍCIO BENEFICIA PACIENTES COM DPOC RUNNING TITLE: EXERCISE TRAINING

The clinical consequences of chronic obstructive pulmonary disease (COPD) include fatigue, dyspnea and progressive impairment of exercise capacity. It also produces significant systemic consequences such as nutritional depletion, physical deconditioning, systemic inflammation, and structural and functional changes in the respiratory and locomotor muscles. Regular exercise provides improvements in the health of patients with stable COPD and can relieve the symptoms, increasing the exercise capacity and improving the quality of life, while also reducing hospitalization and, to some extent, the risk of morbidity and mortality. Training with progressive exercises is associated with metabolic and neurohumoral adaptations, heart rate variability, with adaptations in the pulmonary and skeletal muscles, as well as the inflammatory, cardiovascular and respiratory systems. This review will focus on current knowledge of the mechanisms by which physical training can provide beneficial effects in COPD patients. Results: After analyzing the titles, abstracts and content, out of 500 articles found, 489 were excluded, leaving 11 articles. Studies have shown the beneficial effect of aerobic training on COPD. Conclusion: Physical training should be considered a therapeutic option in patients with COPD, regardless of being terrestrial or aquatic, as it can have beneficial effects on the systems.
