High-intensity breathing exercises for asthma patients

High-intensity Inspiratory Muscle Training in Patients With Asthma

Not applicable Interventional Istanbul Medipol University Hospital · NCT06516848

This study is testing whether high-intensity breathing exercises can help people with severe asthma breathe better and improve their overall quality of life compared to low-intensity exercises.

What this trial studies

This study investigates the effects of high-intensity and low-intensity inspiratory muscle training combined with standard pulmonary rehabilitation on patients with asthma. Participants diagnosed with severe persistent asthma will be randomized into two groups to receive either high or low intensity training over an 8-week period. The training includes a structured program of inspiratory muscle exercises, breathing exercises, and walking training, with sessions conducted online and supervised by a physiotherapist. The aim is to assess improvements in respiratory muscle function, exercise capacity, and overall quality of life.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with severe persistent, non-allergic asthma under treatment and control.

Not a fit: Patients with recent respiratory infections, significant smoking history, or high body mass index may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance respiratory function and quality of life for asthma patients.

How similar studies have performed: Previous studies have shown positive outcomes with inspiratory muscle training in respiratory conditions, suggesting potential success for this approach.

* Being between the ages of 18-65 years
* Having been diagnosed with severe persistent, non-allergic asthma by a pulmonologist in accordance with the Global Initiative for Asthma (GINA) guideline criteria,
* Patients with type 2 inflammation markers. According to accepted standards; peripheral eosinophils \<150/µL and/or negative skin prick test and/or total IgE \<30 kU/L

* Those who were diagnosed at least 6 months ago and are under follow-up and treatment, and/or patients whose asthma is under control

Exclusion Criteria:

* Having recently had a respiratory tract infection recently (within the last month),
* Having a smoking history of more than 10 pack-years or having a history of smoking within 6 months after quitting smoking
