Study on the Influence of High Intensity Inspiratory Muscle Resistance Training on Airway Mucus Secretion and Exercise Endurance of Patients with Bronchiectasis
Objective:To investigate the influence of high intensity inspiratory muscle resistance training on airway mucus secretion and exercise endurance of patients with bronchiectasis.Method:A total of 100 patients with bronchiectasis in Zhangzhou Hospital of Fujian Province from March 2021 to March 2023 were divided into two groups with 50 cases in each group according to the method of random number table.The control group was treated with routine treatment and intervention for bronchiectasis,the observation group was treated with high intensity inspiratory muscle resistance training on the treatment and intervention of control group.Then the total effective rates,sputum excretion volume,airway mucus secretion indexes(dry/wet weight and viscosity of sputum),exercise endurance[6-minute walk test(6MWT)and heart rate(HR)]and life quality[St George's respiratory questionnaire(SGRQ questionnaire)]before and after the intervention of two groups were compared.Result:The total effective rate for bronchiectasis of observation group was significantly higher than that of control group(P<0.05),the sputum excretion volume,airway mucus secretion indexes,exercise endurance and SGRQ questionnaire of two groups before the intervention were compared,the differences were not statistically significant(P>0.05),the sputum excretion volume of observation group at third day and first week after the intervention were significantly more than those of control group,the sputum excretion volume of observation group at second week after the intervention was significantly less than that of control group,after 1 week and 2 weeks of intervention,the airway mucus secretion indexes were significantly lower than those of control group,the 6MWT of observation group at first and second week after the intervention were significantly longer than those of control group,the HR and SGRQ questionnaire were significantly lower than those of control group(P<0.05).Conclusion:The application effect of high intensity inspiratory muscle resistance training in patients with bronchiectasis is better,it can significantly improve the airway mucus secretion and exercise endurance of patients,so its application value in the patients with bronchiectasis is relatively higher.
