Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
6 week training program with a pressure threshold breathing device designed for a combination of inspiratory and expiratory muscle training. The device is a small handheld device which exerts a pressure against inspiration and expiration. The SHAM training (6 weeks) consisted of a training routine with resistance levels set at 15% of maximum inspiratory and expiratory pressures at baseline. 5 days a week a set of 40 breaths (4 times 10 breaths), two times daily, followed by 2 days of non activity. Inspiration to total lung capacity, exhalation to functional residual capacity. Adherence, time spend and exertion was monitored with a diary. This was followed immediately (no washout period) by a real training program (6 weeks) consisting of the same training routine, with resistance set at 60% of maximum inspiratory and maximum expiratory pressures measured after SHAM training.
