Abstract in different language: Cardiac output can be accurately estimated from VO2 (oxygen consumption) during exercise in normal subjects and in patients with heart failure by measuring the LAT (lactate acidosis threshold) or VO2peak (peak oxygen consumption) during bicycle ergometer test. Hence, during step-vice increased workload on bicycle ergometer with continuous measurement of oxygen consumption changes in cardiac output and stroke volume (SV) can be calculated. Our measurement documented usefulness of this method in subjects of different performance level, both men and women. Non-invasive evaluation of cardiac output and stroke volume during spiroergometric stress test enables to extent the information about the health status of the subject and about the functional reserve of his circulatory apparatus. The examples presented in this study prove the applicability of this method in evaluation of fitness level in healthy male and female subjects of different age. The data of cardiac output and stroke volume will be added into the software program of final protocol of complex sports medical examination. This method can enrich the scale of parameters testifying the functional capacity of the subjects.
