Buteyko-based breathing technique training
Brief summary
The purpose of this study is to investigate the effects of a Buteyko-based breathing technique on physiological and psychological parameters in adults with asthma
Detailed description
The investigators explore the effects of a Buteyko-based breathing technique training using a treatment group vs. control group design and a repeated measures design with follow-up measurements 3 and 6 months after the intervention. The sample size calculation was made for an effect of d = .20 with repeated measures, a power of 1- β = .80 and α = .05. Additionally the investigators plan to take measurements (only once) from healthy volunteers matching them (age and gender) with the asthma patients.
Interventions
Patients are trained in various exercises aiming at breath reduction and breath control as introduced by Dr. K. Buteyko
