Abstract

Intense physical work is characterized by activity of physiological mechanisms as interrelated components joint for physical exertion. Definition of a set of individual and typological patterns of the physiological mechanisms’ activity answers the questions related to improvement of the athlete’s potential realization efficiency, definition of the limiting components and body’s reserve capacity, training load management. The study was aimed to assess the relationship between the responses of physiological mechanisms associated with standardized physical exertion and the pre-start state parameters. The athlete was through the step incremental test with the treadmill involving recording of the gas exchange parameters and heart rate to study physiological patterns. The physiological response parameters were calculated relative to the key phases of the exercise test: pre-start state, aerobic and anaerobic thresholds, peak exertion, fast and slow recovery phases. The mathematical model “Horseshoe of Rest” characterizing the athlete’s pre-start state before performing the test was constructed using the T-SNE dimensionality reduction algorithms. The model enables estimation of the release of non-metabolic СО2 throughout the testing period (MIC — 0.29) and the exertion period (MIC — 0.35).
