Summary
Intensive endurance training improved exercise capacity in patients with chronic obstructive pulmonary disease (COPD), but health-related quality of life did not change. The benefits on exercise capacity lasted for one year.
Area of Science:
- Pulmonary Rehabilitation
- Exercise Physiology
- Chronic Obstructive Pulmonary Disease (COPD) Management
Background:
- Chronic obstructive pulmonary disease (COPD) significantly impacts exercise capacity and quality of life.
- Optimizing exercise interventions is crucial for managing COPD symptoms and functional decline.
Purpose of the Study:
- To compare the effects of endurance training versus resistance training and callisthenics on exercise capacity and health-related quality of life (HRQoL) in COPD patients.
- To investigate if COPD severity influences training response and the long-term effects of these interventions.
Main Methods:
- Stratified randomization of 63 COPD patients into endurance (Group A) or resistance/callisthenics (Group B) training groups, twice weekly for 8 weeks.
- Assessment of peak exercise capacity, 12-minute walking distance (12MWD), spirometry, blood gas analysis, and HRQoL before and after training, with follow-ups at 6 and 12 months.
- Training response was analyzed based on COPD severity (moderate vs. severe).
Main Results:
- Peak exercise capacity and 12MWD significantly improved in the endurance group (Group A), but not in the resistance group (Group B).
- No significant changes in HRQoL were observed in either group.
- Training response was comparable between patients with moderate and severe COPD.
- In Group A, 12MWD returned to pre-training levels after one year; in Group B, it fell below pre-training levels.
Conclusions:
- Intensive endurance training for 8 weeks can improve exercise capacity in COPD patients, though the improvement is modest.
- Health-related quality of life did not show significant improvement.
- COPD severity did not impact the response to training.
- Endurance training demonstrated a potential to slow the decline in functional exercise capacity for up to one year post-intervention.
