[Results of respiratory muscle training in patients with chronic obstructive lung diseases with a moderately severe course].

The aim of the study was to testify the effectiveness and acceptance of combination of the resistive inspiratory muscle training and the following walking training in 26 stable COPD pts with FEVI%VC about 50%. Measurements of inspiratory (MIP cm H20) and expiratory (MEP cm H20) muscle strength and also spirometric examinations two times before the training and one time after every month of observation were done. During first 3 months of the training inspiratory resistor (Pflex) was used. Everyday 20 s MVV with smaller orifice of Pflex (strength training) and 30 min quiet breathing by medium orifice of Pflex 3 times a week (endurance training) were performed. In first 3 months of experiment 13 patients resigned of it. Other 13 pts (age 64 +/- 11.9. F-4 with medium FEVI%VC = 47.3 +/- 14.5, MIP = -54.1 +/- 11.4, MEP = = 99.8 +/- 40.5) were trained during 3 months. In 11 of them (FEVI%VC = 50.0 +/- 17.3) MIP improved by 33%. Values of other indices did not change at all. After 3 month of resistive training 11 pts (3-F) were qualified to walking training but only 5 (1-F) of them had finished it. After 5 month of exercises their MIP improved by 74% (p < 0.5) and MEP by 50% (p < 0.05). We conclude that our method of resistive breathing with Pflex is effective and well tolerated by stable COPD pts but accepted only by 50% of them. It may be used as the first step before conditioning training. Inspiratory muscle training is not alternative to pharmacological treatment but is valuable supplementation of it.
