Objective of the study was to investigate the application potential of the method of tissue spectroscopy in the system of integrated assessment of athletes' aerobic endurance. The subjects of the experiment were elite cyclists, who were subject to standardized laboratory tests. The relationship of hemoglobin oxygen saturation was determined in the working and non-working muscles using the InSpectra StO2 tissue spectrometer. It has been found that the degree of muscle hemoglobin oxygen saturation of athletes is closely related with the aerobic metabolism at the general body level. Two threshold points can be clearly observed in a graded load test in the load curve of the muscle hemoglobin oxygenation. The first one coincides with the onset of the anaerobic threshold (AnT), and the second one - with the point of respiratory compensation.

Keywords: aerobic endurance, oxygen, hemoglobin, metabolic state, anaerobic threshold, maximal oxygen consumption test.
