The performance of MVPA for a minimum of 60 min per week can have a beneficial effect, both on lung volumes and on expiratory flow, and led to an achievement of the LLN in FEV.

The clinical course of lung transplantation (LT) is diverse: some patients present chronic lung allograft dysfunction (CLAD) and progressive decline in pulmonary function, but others maintain normal spirometric values and active lives.ObjectivesThe aim of this study was to elucidate whether long-term LT survivors with normal spirometry achieve normal exercise capacity, and to identify predictive factors of exercise capacity.MethodsThis was a cross-sectional multicentre study, where bilateral LT recipients who survived at least 10 years after LT, with normal spirometry, no diagnosis of CLAD and modified Medical Research Council dyspnoea degree ≤2 underwent cardiopulmonary exercise testing (CPET).Results28 LT recipients were included with a mean±sd age of 48.7±13.6 years. Oxygen uptake (V′O2) had a mean±sd value of 21.49±6.68 mL·kg−1·min−1 (75.24±15.6%) and the anaerobic threshold was reached at 48.6±10.1% of the V′O2max predicted. The mean±sd heart rate reserve at peak exercise was 17.56±13.6%. The oxygen pulse increased during exercise and was within normal values at 90.5±19.4%. The respiratory exchange ratio exceeded 1.19 at maximum exercise. The median (25–75th percentile) EuroQol-5D score was 1 (0.95–1), indicating a good quality of life. The median (25–75th percentile) International Physical Activity Questionnaire score was 5497 (4007–9832) MET-min·week−1 with 89% of patients reporting more than 1500 MET-min·week−1. In the multivariate regression models, age, sex and diffusing capacity of the lung for carbon monoxide remained significantly associated with V′O2max (mL·kg−1·min−1); haemoglobin and forced expiratory volume in 1 s were significantly associated with maximum work rate (watts), after adjusting for confounders.ConclusionWe report for the first time near-normal peak V′O2 values during CPET and normal exercise capacity in long-term LT recipients without CLAD.
