Methods: Ninety asthma patients were randomly assigned to either conventional respiratory movement group (BTE; 2 sessions/week; 25 min/session) or inspiratory muscle training group (IMT; 5 days/week, 2 sessions/day, 30 breaths/session, and intensity set at 50% PImax). Outcome measurements were performed before and after the intervention, including international physical activity questionnaire (IPAQ), three-day physical activity log (3-D PAL), asthma control test (ACT), asthma control questionnaire, ACQ), pulmonary function tests, and six-minute walk test (6MWT). Results: After 12 weeks of breathing exercise or inspiratory muscle training intervention, the six-minute walking distance increased by 25 m in the BTE group and 37 m in the IMT group, but there was no difference between the two groups. In the IMT group, the FVC progressed by 4.25% (79.38±13.26 vs 83.63±11.54) and the FEV1 improved by 1.61% (79.12±15.84 vs 80.73±12.55), whereas these indicators did not change in the BTE group. The PImax increased by 14.3 cmH2O (71.83±31.29 cmH2O vs 86.13±32.92 cmH2O, p<.05) in the BTE group and by 25.77 cmH2O (62.17±25.37 cmH2O vs 87.93±24.8 cmH2O, P<.05) in the IMT group, but there was no difference between the two groups. Similarly, PEmax, ACT and ACQ were significantly different before and after intervention, but there was no difference between the two groups. Conclusion: After 12 weeks of breathing exercise or inspiratory muscle training intervention, inspiratory muscle training is more effective in promoting the improvement of cardiopulmonary function, asthma control test and respiratory muscle strength than breathing exercise, but the same effect between the two groups.
