INTRODUCTION
RESULTS I.
The Hungarian Transplant Team (with 46 participants)
won 89 medals at the World Transplant Games in
Göteborg, 2011 .
The low availability of donor organs put a claim on the
long-term successful transplantations. The physical
capability is a useful method to measure the quality of
life.
The cardiorespiratory capacity provides background
for the metabolic changes.
The maximal oxygen uptake (VO2max) is an optional
measurement to assess liver or renal transplant
patients.1 Also, it provides an objective tool for the
measurement of the functional capacity of
posttransplant patients. Exercise limitation and loss of
aerobic capacity are common among patients with
chronic illness or with end-stage liver disease.2
Cardiopulmonary exercise testing (CPET) has become
an important clinical tool to evaluate exercise capacity
and predict outcome in patients with heart failure and
other cardiac conditions. The peak oxygen uptake
(VO2max) and the oxygen pulse (O2p) could be predictive
in the long-term graft survival.3-4
Our aim was to determine the cardiorespiratory
capacity of the athletes participating in the 2011 World
Transplant Games in the aspects of the athletic
performance.

METHODS
Twenty-five liver and kidney transplant athletes (11
women, 14 men; age: 39.3±15) were examined. Maximal
cardiorespiratory capacity was measured with a vita
maxima test, using modified Bruce protocol on treadmill
(Schiller AT-104).
Before the exercise test echocardiography, 12-lead
ECG, graft-specified venous blood test were performed.
Static and dinamic spiroergometric parameters were
recorded at rest. During the ergospirometry test we
continually registered heart rate (HR) with a 12-lead ECG
system, and used a breath-by-breath gas analyzer
(Ganshorn PowerCube-Ergo system) to measure
respiration parameters (VO2, VCO2, VE, RQ). Anaerobic
threshold (AT) was also registered. In the restitution
phase, heart rate and blood pressure were documented.

Aerob capacity, sport performance and quality of life are highly related to each other. Good graft function after
successful solid organ transplantation provides the base for cardiopulmonary exercise capacity.

High cardiorespiratory capacity providing proper graft oxygenation is an important factor in long-term graft
survival. Cardiorespiratory capacity is highly connected to physical activity and strongly related to sport performance.

The excellent spiroergometric performance of the athletes contributed to their outstanding sport results in the
2011 World Transplant Games. Objective, functional data (VO2max, O2p) from the spiroergometry test might be used in
the prediction of long-term graft survival and used for sport program recommendation for transplanted patients.
However, this requires further studies.

CONCLUSION
The lack of long-term longitudinal studies of transplanted athletes compared to non-athletes complicate to
estimate the impact of regular physical exercise on the graft survival range.
