Quantitative assessment of the functional support of sports activities, as a reflection of the systematic approach, allows to identify the features of the body of athletes, to plan the training process and possible deviations in the action of multiple exogenous and endogenous factors. In accordance with the methodology of artificial intelligence and machine learning, the most informative indicators were determined, which determine the success of sports activities. This made it possible to determine the peculiarities of the functioning of the cardiovascular system of elite biathletes, which provides and limits physical performance. As a result of the research, functional models of high-, medium-and low-skilled biathletes have been built that will improve the training process.

Резюме. В результате анализа публикаций в украинских профессиональных изданиях с 2006 по 2011 г. установлено уменьшение количества статей, посвященых проблемам детей раннего и дошкольного возраста, что составляет лишь 3 % всех публикаций, у 58 % из них расскрываются вопросы оптимизации процесса физического воспитания в дошкольных образовательных учреждениях. Среди публикаций зарубежных авторов 36 % посвящены проблемам организации физического воспитания и физической подготовлености, развития и здоровья детей. В изданиях «Молодая спортивная наука Украины» и «Педагогика, психология и медико-биологические проблемы физической культуры и спорта» содержится большинство публикаций, посвященных вопросам здоровья детей дошкольного возраста и их физического воспитания. Ключевые слова: дети раннего дошкольного возраста, физическое воспитание, физическое состояние, научные исследования. Summary. This study analyzes publications in Ukrainian professional editions from 2006 to 2011 years and shows visible decline in the number of articles dedicated to the problems of preschool children. They represent only 3 % of all publications. The 58 % of these articles concern optimization of physical education in preschool educational institutions. The 36 % of foreign publications dedicated to the physical education organization and the same proportion covers the topic of motor competence, physical development and health in children. The professional editions "Young Sports Science of Ukraine" and "Pedagogics, psychology, medical-biological problems of physical training and sports" contain the majority of the publications dedicated to the preschool children health and physical education.

Introduction. Adaptation of the athlete's organism with auditory deprivation to training and competitive activity is ensured by the active participation of the central nervous system, sensory systems, among which the important role is played by visual, vestibular, kinesthetic, tactile-vibration analyzers, which ensure the quality of movement. In this regard, studying the activity of sensorimotor systems of healthy athletes and hearing impaired will determine the ways of correction of the motor activity of the latter. The objective - study and comparative analysis of physiological features of sensorimotor systems of qualified hammer throwers (healthy and hearing impaired). Materials and methods. Research methods: analysis, generalization and systematization of data scientific and methodological literature; psychophysiological methods (simple visual-motor reaction; reaction to a moving object; tepping test; choice and discrimination reaction; critical part of light flickering; attention assessment); methods of mathematical statistics. Nine female athletes specializing in hammer throwing participated in the study: 7 of them are masters of sports of Ukraine, 2 - masters of sports of international class (5 female athletes have hearing impairments, 4 are healthy). The studies were conducted in October-November 2019 at the Donetsk Regional Children's and Youth Sports School for Persons with Disabilities (Mariupol). Results. The studies suggest that the thrower hammer with hearing problems (especially in persons with bilateral sensorineural deafness), in most cases there is a lack of speed of receiving and processing visual information, poor concentration and stability of attention, increasing the number of errors compared to almost healthy athletes. It should also be noted in hammer throwers with hearing impairment that there is an imbalance of nerve processes with a predominance of inhibition, their weakness and inertia. Conclusions. The data obtained confirm the need for the development of a training program, the basis of which is a deliberate impact on visual and vestibular analyzers in order to correct existing abnormalities and compensate for hearing impairment by further improving the functioning of the motor analyzer. Key words: sensorimotor systems, functional state, hammer throwers, hearing defects.
