Определение набора индивидуально-типологических паттернов активности физиологических механизмов отвечает на вопросы, связанные с повышением эффективности реализации потенциала спортсмена, определением лимитирующих звеньев и резервных возможностей организма, управлением тренировочной нагрузкой. Целью работы было изучение взаимосвязи реакции физиологических механизмов при выполнении стандартизированной физической нагрузки с показателями «предстартового» состояния. Для исследования физиологических закономерностей спортсмен выполнял ступенчато-возрастающий тест на беговой дорожке с фиксацией показателей газообмена, частоты сердечных сокращений. Расчет показателей физиологических реакций производили относительно ключевых фаз нагрузочного тестирования: «предстартового» состояния, аэробного и анаэробного порогов, пика нагрузки, фаз быстрого и медленного восстановления. С использованием алгоритмов понижения размерности T-SNE была разработана математическая модель «Подкова_покоя», характеризующая «предстартовое» состояние спортсмена перед выполнением теста. Модель позволяет оценить уровень выделения неметаболического СО2 за весь период тестирования (MIC — 0,29) и за период нагрузки (MIC — 0,35).</p></abstract><trans-abstract xml:lang="en"><p>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, rapid 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).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спортсмен</kwd><kwd>физическая нагрузка</kwd><kwd>«предстартовое» состояние</kwd><kwd>моделирование энергообеспечения</kwd><kwd>порог анаэробного обмена</kwd><kwd>физиологическая реакция</kwd><kwd>стандартизированная нагрузка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>athlete</kwd><kwd>physical activity</kwd><kwd>pre-start state</kwd><kwd>modeling of energy supply</kwd><kwd>threshold of anaerobic metabolism</kwd><kwd>physiological response</kwd><kwd>standardized load</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ожгибесова М.
