Abstract

Rationale: The effects of a 9 months inspiratory muscle training in addition to an outpatient exercise training program on lung and respiratory muscle function indices, exercise capacity and quality of life were evaluated in patients with COPD.
Methods: 40 patients with moderate COPD were randomly assigned into a treatment group (TG) and a control group (CG), 31 patients completed the follow up. TG (n = 16; mean age, 64.4 yrs; FEV₁, 64.3 % pred) and CG (n = 15; mean age, 62.8 yrs, FEV₁, 63.2 % pred) received a 9 months training program under outpatient conditions, mainly consisting of endurance and strength training. TG additionally underwent training of strength and endurance of the inspiratory muscles with the Respifit S on three days per week.
Results: Both groups showed a significant increase in peak VO₂ (TG: 18%; p=0.0001 and CG: 17%; p=0.0001), in work rate at the ventilatory anaerobic treshold (TG: 25%; p=0.0001 and CG: 24%; p=0.0001), in hand grip strength (TG: 8%; p=0.0001 and CG: 9%; p=0.0001), 6 MWD (TG: 118m; p=0.0001 and CG: 123m; p=0.0001) and in Pimax (TG: 17%; p=0.0005 and CG: 7%; p=0.036). There were no statistically significant differences between the groups. The QOL obtained by use of the SF36-questionnaire showed intergroup differences: Physical health index score improved in TG (p=0.004) but not in CG (p=0.17). Mental health index score improved in CG (p=0.004) but not in TG (p=0.22). The total score of the SGRQ decreased significant in both groups.
Conclusion: The exercise training program improved physical fitness and quality of life. Additional inspiratory muscle training did not lead to substantial further benefits.
