Exercise Limitation in Trained Heart and Kidney Transplant Recipients: Central and Peripheral Limitations

Despite regular training, the decreased mechanical efficiency reflected by an increased Vo2/treadmill speed relationship suggests a peripheral limitation in both heart and kidney transplant patients. Furthermore, exercise limitations in HTRs likely arose from both central and peripheral factors, in view of their specific HRR reduction. These factors probably contributed to the decreased speed and Vo2 observed in the HTR group.
