Summary

The aim of our study is to investigate the effect of high-intensity interval exercise (HIIE) on the symptoms of bronchiectasis in patients with the disease. The main questions it aims to answer are:

1. Does HIIE improve respiratory function in patients with bronchiectasis?
2. Does HIIE increase functional capacity, peripheral muscle strength, and quality of life in patients with bronchiectasis?
3. Does HIIE reduce the severity of dyspnea, cough symptoms, and fatigue in patients with bronchiectasis?

The study was designed as a randomized controlled trial. Participants were divided into two groups: intervention and control.

Participants will:

The intervention group will receive HIIE training three days a week along with airway clearance techniques.

The control group would receive only airway clearance techniques. Airway clearance techniques will be provided clinically (three days a week) and at home, according to the needs of the individuals each day of the week.

Conditions

  • Bronchiectasis, Non-Cystic Fibrosis
  • High Intensity Interval Exercise

Interventions

OTHER

high-intensity interval exercise

The high-intensity interval exercise (HIIE) protocol (4×4 model: 4 minutes at 85-95% maximum heart rate, with 3 minutes of active recovery at 60-70% in between), will be applied 3 days a week for 8 weeks using a treadmill or cycle ergometer, taking into account the participants' physical characteristics and safety requirements.

OTHER

Airway clearance tecniques

Among the airway clearance techniques, the active cycle of breathing techniques (ACBT) and manual techniques will be applied. Additionally, the autogenic drainage technique will be taught to patients for them to practice at home. Airway clearance techniques will be demonstrated to the patients practically and they will be asked to perform them daily (3 days a week in the clinic) as needed.
