Background: The effects of inspiratory muscle training are widely investigated. Positive effects in healthy humans are established (Hart et al., 2011). Beckerman et al. (2005) attested an increase of PImax, distance of 6 minute walking test and Borg Scale data in COPD patients. Petrovic et al. (2012) also tested COPD patients (Gold Standard II & III). 8 weeks after inspiratory muscle training an increase of PImax and endurance time was discovered. The main objective of this study was to determine the optimal intensity and frequency of IMT in outpatient rehabilitation and long term compliance after rehabilitation finish.

Methods: 42 patients were randomized in a training group (with IMT) and control group (no IMT). The patients started with a low load (20 – 30% of PImax) which they increased during the 20 training sessions till they received a maximum of 70% of Pimax. They startet twice a week with 30 deep breathes supervised by a sport scientist followed by a training at home every other day. After 20 sessions the additional test was done. To figure out the long term compliance, we called the patients once a month after rehabilitation was finished.

Results: There was statistically high significant increase in Pi-Max (p = 0,000) and COPD assesment test (p = 0,001) in experimental but not in control group. 8 out of 10 patients continued training every other day.

Conclusions: The findings of this study show that the outcome of IMT every other day is positive in different parameters. The goal of the outpatient rehabilitation is to prepare the patients for the home routine training. Additional to endurance, weight and coordination training, IMT is recommended. We will do further investigation to find out the optimal intensity of each training session.
