The study analyzes the dynamics of exercise tolerance indicators in patients with chronic obstructive pulmonary disease (COPD) during the course of respiratory rehabilitation. The research focuses on evaluating the effectiveness of different rehabilitation methods aimed at improving patients’ physical performance, reducing dyspnea, and enhancing overall quality of life. Results demonstrate a significant increase in exercise tolerance, improved respiratory function, and reduced symptoms of fatigue after completing the rehabilitation program. The findings highlight the importance of individualized respiratory therapy and regular physical training as key components of comprehensive COPD management.
