Circuit and Resistance Training in COPD

Chronic Obstructive Pulmonary Disease (COPD) is characterized by a combination of pulmonary and extra-pulmonary manifestations that directly contribute to the increase in exercise intolerance and dyspnea, especially in more advanced stages of the disease, leading to physical inactivity and consequent worsening of these signs and symptoms. COPD is a preventable and treatable lung disease. Solid evidence shows that physical training, the most important component of a Pulmonary Rehabilitation program (PR), reduces dyspnea and fatigue, increases exercise performance, and improves peripheral muscle strength, functional capacity, control of emotional function and quality of life of these patients\' lives. Multicomponent physical training (MPT) proposes the performance of 3 or more components or physical training modalities within the same session and has demonstrated its benefits in several studies involving the elderly population. The main objective of the study will be to determine the effects of circuit training and resistive exercises on pulmonary function and physical parameters in population with COPD. The study will be a randomized clinical trial and conducted for a duration of 09 months after the approval of synopsis. Data will be collected with Non-Probability Convenience Sampling Technique. A sample of 48 COPD patients will be recruited from DHQ Muzaffargarh. This will be a double blinded study with patients and assessor blinded to the intervention. COPD patients will be divided into two groups with group 1 treated with circuit training and group 2 treated with resistance exercise for duration of 10 weeks. Baseline values for Respiratory parameters and physical parameters will be collected and after 5 weeks and 10 weeks of treatment. Data will be analyzed using SPSS v 26. For within the group analysis Repeated Measure ANOVA will be used. For across the group analysis, independent sample T test will be used to compare the mean differences.
