Effects of TPB-Based Cadence Exercise and Breathing Training on Physiological Parameters and Quality of Life in Patients With COPD (COPD)
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
This randomized controlled trial aims to evaluate the effects of a Theory of Planned Behavior (TPB)-based intervention incorporating cadence exercise and breathing training on physiological parameters and quality of life in patients with chronic obstructive pulmonary disease (COPD). Eligible participants will be randomly assigned to receive breathing training, cadence exercise, a combined intervention of breathing training and cadence exercise, or usual care. The intervention will be conducted for 12 weeks, with assessments at baseline, Week 8, and Week 12. The study will evaluate changes in physiological parameters, exercise capacity, respiratory muscle strength, and quality of life. The findings may provide evidence for developing behavioral interventions to support pulmonary rehabilitation and improve health outcomes in people with COPD.

Descrição detalhada
Chronic obstructive pulmonary disease (COPD) is a chronic respiratory condition that can cause persistent respiratory symptoms, reduced exercise capacity, impaired respiratory muscle function, and decreased quality of life. Pulmonary rehabilitation and regular physical activity are important components of COPD management; however, adherence to exercise and respiratory training may be affected by individual behavioral factors.
This randomized controlled trial is designed based on the Theory of Planned Behavior (TPB), which proposes that attitudes, subjective norms, and perceived behavioral control influence behavioral intention and subsequent health behaviors. The study aims to evaluate whether a TPB-based intervention incorporating cadence exercise and breathing training can improve physiological parameters and quality of life in patients with COPD.
Eligible participants will be randomly assigned to one of four groups: a breathing training group, a cadence exercise group, a combined breathing training and cadence exercise group, or a usual-care control group. Participants in the breathing training group will perform respiratory muscle training using an adjustable respiratory muscle training device. Participants in the cadence exercise group will perform walking exercise guided by a metronome at a predetermined cadence. Participants in the combined intervention group will receive both breathing training and cadence exercise. The usual-care group will receive routine clinical care.
The intervention period will be 12 weeks. Participants will be assessed at baseline (T0), Week 8 (T1), and Week 12 (T2). Outcome assessments will include physiological parameters, respiratory muscle strength, pulmonary function, exercise capacity, dyspnea, and health-related quality of life. Physiological and functional outcomes will include oxygen saturation, heart rate, respiratory rate, maximal inspiratory pressure, maximal expiratory pressur and the six-minute walk test. Quality of life and COPD-related symptoms will be assessed using validated instruments.
The study will also assess TPB-related constructs, including attitude, subjective norm, perceived behavioral control, and behavioral intention, to explore behavioral factors associated with adherence to the intervention. The study findings are expected to provide evidence regarding the effectiveness of cadence exercise and breathing training, individually and in combination, and to contribute to the development of behaviorally informed pulmonary rehabilitation strategies for patients with COPD.
