The effects of combined respiratory muscle and exercise training in children with bronchial asthma

Abstract

Abstract Objective:To investigate the effects of combined respiratory muscle and exercise training on inspiratory muscle strength, exercise capacity, lung function, asthma control the quality-of-life in children with asthma. Design：randomisd trail Methods:Fifty children with asthma, who were treated in XX hospital in Chongqing between May and December 2021, were selected and randomly divided into a rehabilitation group and a control group by using a random number table. The control group was given routine drug treatment and health education while the rehabilitation group received a combination of respiratory muscle and exercise training. Results:After three months of treatment, the maximum inspiratory pressure, level of asthma control and quality-of-life in the rehabilitation group were significantly improved when compared with those in the control group (P＜0.05); there were no significant differences in the 6-minute walking test and lung function (P＞0.05). After three months of treatment, all outcome indicators in the rehabilitation group were significantly improved when compared to those before treatment (P＜0.05). The mean maximum inspiratory pressure and some indices of pulmonary function in the control group were significantly improved when compared to those before treatment (P＜0.05). Conclusion: Combining respiratory muscle and exercise training significantly improved inspiratory muscle strength, the level of asthma control and the quality-of-life in children with asthma. More research is needed to explore its role in asthma in the future.
