Aerobic versus high-intensity interval exercise for people awaiting lung transplant
Comparison of the Effects of Continuous Aerobic Exercise Training and High-Intensity Interval Exercise Training on ICF-Based Assessments in Lung Transplant Candidates
This trial tests whether short bursts of high-intensity interval training or longer moderate aerobic sessions better improve walking distance and daily function for people with interstitial lung disease who are on the lung transplant waiting list.

What this trial studies
This is a randomized, prospective trial that will assign lung transplant candidates with interstitial lung disease to either low-volume high-intensity interval training (LV-HIIT) or moderate-intensity continuous training (MICT) over an 8-week supervised program using an ergometer cycle. The trial plans to enroll about 34 participants (17 per group) and will compare changes in exercise capacity (6-minute walk test), pulmonary function (FEV1, FVC, DLCO), comorbidity burden, activities of daily living, and quality of life before and after the intervention. Training intensity and duration differ between groups (30-second high-intensity intervals versus longer-duration moderate efforts), but total program length and supervision are matched. Outcomes include functional measures aligned with ICF domains to capture changes in activity and participation relevant to transplant candidates.
Who should consider this trial
Good fit: Adults (18+) with interstitial lung disease who are listed for lung transplantation, have dyspnea of ≥2 on the mMRC scale, can ambulate, and are willing and able to attend regular supervised exercise sessions (including those on long-term oxygen) are ideal candidates.
Not a fit: People experiencing an acute exacerbation, with a history of exertional syncope, with excluded diagnoses such as sarcoidosis, or who are non-ambulatory or medically unstable are unlikely to benefit or be eligible for this program.
Why it matters
Potential benefit: If successful, the preferred training approach could increase pre-transplant exercise capacity and functional status, which may lower risk and improve outcomes before and after transplantation.
How similar studies have performed: Pulmonary rehabilitation, including both HIIT and moderate continuous aerobic training, has improved exercise capacity in COPD and some ILD populations, but direct randomized comparisons specifically in lung transplant candidates are limited.
