Effect of exercise rehabilitation on breath muscles in COPD patients

This study aimed to determine the effect of exercise rehabilitation on the breathing muscles of Chronic Obstructive Pulmonary Disease (COPD) patients. Thirty patients (age 52 ± 0.66 years; body mass 66.15 ± 0.75 kg; height 176.17 ± 2.45 cm) with COPD were included in the study. The study used the experimental method by designing a three-month exercise rehabilitation program and using specific exercises to help patients reduce shortness of breath and strengthen their inspiratory and expiratory muscles. The current study was conducted at Babylon's pulmonary rehabilitation center. The Forced Expiratory Volume in the first second (FEV1), the Maximum Inspiratory Pressure (PImax), the maximum expiratory pressure (PEmax), and shortness of breath were all measured. The result shows that the difference in the shortness of breath (Borg Scale) between the pre and post-tests is insignificant at the error rate (5%). Furthermore, the value of calculated T (1.66) is smaller than the value of tabular T (2.57), indicating that there has been no improvement in the level of shortness of breath for the control group. The difference in the level of shortness of breath shown in the table is significant at the error rate (5%). Furthermore, the pre- and post-tests are calculated as T(3.24), greater than the value of tabular T (2.57). Exercise rehabilitation altered FEV1, PImax, PEmax, and shortness of breath in COPD patients in the experimental group, pre-and post-tests supporting the experimental community, suggesting that physical activity affected FEV1, PImax, PEmax, and shortness of breath. According to our study, physical exercise improves COPD patients' respiratory muscles. This study concluded that patients expressed a desire to continue the exercise.
