Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable lung disease. People with COPD must work harder to breathe, which can lead to shortness of breath and/or feeling tired. Early in the disease, people with COPD may feel short of breath when they exercise. As the disease progresses, it can be hard to breathe out (exhale) or even breathe in (inhale). A person with COPD may have obstructive bronchiolitis emphysema, or a combination of both conditions. There is variety of treatment like breathing exercises, inspiratory muscle training exercises, resistance training and aerobic exercise to improve lung function as well as to decrease the chances of cardiopulmonary complications. the purpose of this study it to observe the effects of hand gripping isometric exercises on pulmonary functions in COPD patients. Study design will be randomized clinical trial in which experiment group will receive isometric training with resistance training and other group will only receive resistance training . Total forty eight participates will recruited with convince sampling, after that we will use simple random sampling to divide the patient into both equal groups. Digital spirometry will be used to document the pulmonary function also to observe the difference in post treatment.Data analysis will be done using SPSS version 25.
