This randomized controlled trial investigated the effects of progressive inspiratory muscle training (IMT) on lung volume and respiratory strength in 30 patients with pre-dialysis chronic kidney disease (CKD). Results indicated significant increases in thoracic cavity volumes and inspiratory muscle strength in both the experimental and control groups, with the experimental group showing a notable increase in pulmonary thoracic cavity volume (F=3.698; p=0.042).
Key findings
- All thoracic cavity volumes significantly increased after 8 weeks of training.
- Inspiratory muscle strength improved from 73.88 to 90.35 cmH2O in the experimental group.
- Expiratory muscle strength increased from 97.71 to 108.53 cmH2O in the experimental group.
- Progressive-load IMT was not superior to minimal-load training.
Why it matters
The findings highlight the potential benefits of inspiratory muscle training in enhancing respiratory function in patients with chronic kidney disease, which may improve their overall health status and quality of life.
