TPB-based cadence exercise and breathing training for COPD patients
Official title: The Effects of a Theory of Planned Behavior-Based Intervention Incorporating Cadence Exercise and Breathing Training on Physiological Parameters and Quality of Life in Patients With Chronic Obstructive Pulmonary Disease
Run by Fu Jen Catholic University Hospital · NCT07860008 · Data updated 2026-11-12
A TPB-based program tests whether breathing training, cadence-guided walking, or both can improve lung function, exercise capacity, and quality of life in adults with COPD.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 40 or older with COPD who can consent and safely perform respiratory training and cadence-guided exercise.
✕Probably not a fit
Patients with unstable COPD, recent severe cardiac or musculoskeletal issues, or cognitive barriers that prevent participation may not benefit.

What this trial studies
This randomized trial compares four groups: breathing training, cadence-based walking, both interventions, and usual care over 12 weeks. Participants are adults 40 and older with COPD, assigned at random to one of the four arms, with assessments at baseline, week 8, and week 12. The study uses a Theory of Planned Behavior framework to address attitudes, social norms, and perceived control as they relate to adherence to the training. Primary outcomes include physiological parameters, exercise capacity, respiratory muscle strength, and quality of life. The aim is to determine if TPB-influenced interventions can enhance pulmonary rehabilitation outcomes in COPD.
Why it matters
Potential benefit: If successful, the interventions could improve physical function and life quality for COPD patients and support more effective pulmonary rehabilitation strategies.
How similar studies have gone: Prior behavioral and exercise-based COPD interventions have shown variable improvements; this TPB-based approach is novel in combining breathing and cadence exercise with a behavioral framework.
