Although currently moderate and high intensity concurrent physical exercise is prescribed in populations with special needs due to its greater effect on physical condition and health‐related quality of life (HRQOL), there are no data in the liver transplantation (LT) setting. The aim of this study is to evaluate changes in maximal strength, aerobic capacity, body composition, liver function, and HRQOL in LT patients after a moderate‐to‐high intensity combined resistance‐endurance training. Six months after LT, 54 patients were randomized into 2 groups: intervention group (IG) and control group (CG). A total of 50 patients completed the study with repeat testing at 6 and 12 months after LT. The IG completed a 6‐month exercise training program, consisting of exercising 2 days for 24 weeks in the hospital facilities, whereas the CG followed usual care recommendations. Patients completed a 5‐multijoint exercise circuit with elastic bands involving the major muscle groups. The effects of the concurrent training program on maximal oxygen consumption, overall and regional maximal strength, body composition, liver function, and HRQOL were analyzed. The IG showed a significant improvement (P < 0.05) in outcome measurements compared with the CG in aerobic capacity, hip extension, elbow flexion, overall maximal strength, physical functioning, and vitality of HRQOL, whereas no changes were observed in body composition and liver function tests. In conclusion, this is the first study that combines supervised resistance and aerobic training performed at moderate‐to‐high intensity in LT recipients. It results in significant improvements in aerobic capacity, maximal strength, and HRQOL. Liver Transplantation 23 1273–1281 2017 AASLD.
