Who could benefit from this research

Could help

Ideal candidates are adults who are listed for lung transplantation and show signs of physical frailty, low strength, or low activity.

Less likely to help

People who are not on a lung transplant list, are not physically frail, or who cannot safely participate in exercise because of unstable medical conditions may not benefit from this program.

What this research studies

You would be offered a personalized exercise and lifestyle program adapted from geriatric and pulmonary rehabilitation approaches to address weakness, muscle loss, inflammation, and low activity. The team at UCSF working with geriatrics, pulmonary rehab, and exercise physiologists would tailor supervised sessions and home-based exercises to your needs. Researchers will collect measures like strength, body composition, activity levels, and blood markers before and after the program to track change. The intervention is designed specifically for people listed for lung transplant to try to improve function before and after surgery.

Why it matters

Potential benefit: If successful, this program could improve strength and fitness, reduce complications around transplant, and increase chances of surviving and recovering after transplant.

How similar studies have gone: Exercise and lifestyle programs have improved frailty and physical function in older adults, but applying these interventions specifically to lung transplant candidates is a novel approach that has not yet been proven.
