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.

Summary
Brief summary
Purpose of the current investigation is to determine if a 6 week training program with a respiratory threshold loaded breathing device increases maximum inspiratory and expiratory pressure, increases peak inspiratory and expiratory flow, lung volumes, changes flow use during saxophone performance, sound and playing comfort in healthy saxophone players.
