Heart transplantation is the long-term treatment for children and adults with advanced heart failure. Post-transplant outcomes have improved over time, such that 50% of pediatric heart transplant recipients (HTR) remain alive with a need for re-transplantation 17-years following the initial transplant. With improved short- and medium-term outcomes, focus has shifted towards optimizing long-term survival and reducing transplant-associated morbidities. This includes strategies aimed at optimizing cardiorespiratory fitness and physical activity levels. Pediatric and adult HTRs have reduced exercise capacity compared with the general population. Previous groups have shown gradual improvements in heart rate response to exercise and exercise capacity in pediatric HTRs. However, after an initial improvement, exercise capacity appears to plateau, or even decline in pediatric HTRs, and remains s
