Abstract：Objective To explore the application effect of exercise and breathing training in the rehabilitation of chronic obstructive pulmonary disease. Methods A total of 100 patients with chronic obstructive pulmonary disease admitted to Yunyang District People′s Hospital of Shiyan City from February 2020 to February 2021 were selected as the research objects, and they were divided into the control group and the study group according to the random number table method, with 50 cases in each group. The control group was treated with routine rehabilitation, while the study group was treated with exercise and breathing training on the basis of the control group. The scores of modified British medical research council (mMRC), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC) and generic quality of life inventory-74 (GQOL-74) before and after treatment were compared between the two groups. Results Before treatment, there was no significant difference in the mMRC score between the two groups (P>0.05). After treatment, the mMRC scores of the two groups were lower than those before treatment, and the mMRC score of the study group was lower than that of the control group, the differences were statistically significant (P<0.05). Before treatment, there were no significant differences in FEV1 and FVC between the two groups (P>0.05). After treatment, FEV1 and FVC of the two groups were higher than those before treatment, and FEV1 and FVC of the study group were higher than those of the control group, the differences were statistically significant (P<0.05). Before treatment, there was no significant difference in GQOL-74 scores between the two groups (P>0.05). After treatment, GQOL-74 scores of the two groups were higher than those before treatment, and GQOL-74 score of the study group was higher than that of the control group, the differences were statistically significant (P<0.05). Conclusion The effect of exercise and breathing training in the rehabilitation treatment of patients with chronic obstructive pulmonary disease is remarkable. It can effectively alleviate the symptoms of dyspnea, improve the pulmonary function and the quality of life of patients. It is worthy of clinical promotion.
