Protein Supplementation to Enhance Exercise Capacity in COPD

Status Completed

Clinical Trial Summary

Chronic obstructive pulmonary disease (COPD) is a common smoking-related lung disease.

Pulmonary Rehabilitation (PR) is a six-week supervised group exercise and education class. PR is an effective intervention in COPD to reduce symptoms, improve exercise performance and prevent exacerbation. Exercise intolerance/limitation is one of the commonest issues with COPD patients and this may be compounded by reduced muscle mass and malnutrition. COPD patients lose body weight and skeletal muscle mass which leads to muscle weakness and dysfunction, thus impacting functional ability and quality of life. Muscle weakness is caused by a prolonged sedentary lifestyle and voluntary immobilization. Importantly, being under-weight is associated with an increased risk of mortality in COPD.

Nutritional supplementation have been used to overcome malnutrition in COPD patients. It has been shown that nutritional support integrated with exercise training can improve exercise activity, decreased the risk of mortality, and improve muscle strength in undernourished COPD patients. However, uptake of nutritional supplementation during pulmonary rehabilitation, where the potential benefit may be greatest, has been limited by the absence of rigorous evidence-based studies supporting use.

Investigators want to investigate the effect of a nutritional supplement during a PR program on exercise capacity in COPD patients. Investigators will collect demographic data, distribute questionnaires, measure exercise performance, and some additional measurements.
