Изучение функционального состояния организма подростков при  когнитивной деятельности с  использованием электронных устройств приобретает большое значение из-за  внедрения в  образовательный процесс информационно-компьютерных технологий. Выявление особенностей реактивности организма обучающихся при  выполнении когнитивной деятельности в  цифровой среде будет способствовать как оптимизации обучения, так и здоровьесбережению.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Изучить вегетативную регуляцию сердечного ритма, электродермальную активность, мозговое кровообращение и уровень кортизола в  слюне при  выполнении подростками когнитивного теста на электронных устройствах (планшет, ноутбук) и бумажном носителе.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Методами анализа вариабельности сердечного ритма, электродермальной активности, реоэнцефалографии и  иммуноферментного определения кортизола в слюне обследовано 48 подростков при выполнении когнитивной нагрузки на электронных устройствах.</p></sec><sec><title>Результаты</title><p>Результаты. При  выполнении подростками когнитивной нагрузки на электронных устройствах происходит изменение показателей вариабельности сердечного ритма, электродермальной активности и мозгового кровообращения. Когнитивная деятельность в цифровой среде вызывает рост симпатических влияний на сердечный ритм при снижении парасимпатической активности, увеличение интегративного показателя кожногальванической реакции, повышение тонуса сосудов и снижение интенсивности мозгового кровотока. Каждый четвёртый подросток испытывает упреждающее возбуждение эндокринной системы перед выполнением когнитивного теста. Корреляционный анализ выявил большое количество корреляционных связей между изучаемыми показателями как  в  исходном состоянии, так и в ходе когнитивной деятельности.</p></sec><sec><title>Заключение</title><p>Заключение. Большое количество корреляционных связей как в исходном состоянии, так и при выполнении когнитивного теста между показателями вариабельности сердечного ритма и  концентрацией кортизола, параметрами мозгового кровообращения свидетельствует о сохранении жёсткой системы нейровегетативной и гуморальной регуляции сердечного ритма при использовании электронных устройств по сравнению с бумажным носителем.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Studying the functional state of the body of adolescents when they preform cognitive activity using electronic devices is of great importance due to the introduction of information and computer technologies into the educational process. Identifying the characteristics of the reactivity of students’ bodies when performing cognitive activities in  a  digital environment will contribute to  both optimization of learning and health protection.</p></sec><sec><title>The aim</title><p>The aim. To study the autonomic regulation of heart rate, electrodermal activity, cerebral circulation and the level of cortisol in saliva when adolescents performed a cognitive test on electronic devices (tablet, laptop) and on paper.</p></sec><sec><title>Materials and  methods</title><p>Materials and  methods. Using analysis of heart rate variability, electrodermal activity, rheoencephalography and enzyme-linked immunosorbent determination of cortisol in saliva, цe examined 48 adolescents while performing a cognitive activity on electronic devices.</p></sec><sec><title>Results</title><p>Results. When adolescents perform cognitive activity using electronic devices, we can register changes in heart rate variability, electrodermal activity and cerebral circulation. Cognitive activity in a digital environment causes an increase in sympathetic effect ontheheart rate with adecrease inparasympathetic activity, anincrease inthe integrative indicator ofgalvanic skin response, invascular tone and adecrease in the cerebral blood flow intensity. One in four adolescents experiences anticipatory stimulation of the endocrine system before taking a cognitive test. Correlation analysis revealed alarge number of correlations between the studied indicators both in the initial state and during cognitive activity.</p></sec><sec><title>Conclusion</title><p>Conclusion. A large number of correlations, both in the initial state and during the cognitive test, between heart rate variability and cortisol concentration, cerebral circulation parameters indicate the preservation of a rigid system of neurovegetative and humoral regulation of heart rate when using electronic devices compared to paper-based media.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>подростки</kwd><kwd>когнитивная нагрузка</kwd><kwd>вариабельность сердечного ритма</kwd><kwd>электродермальная активность</kwd><kwd>мозговое кровообращение</kwd><kwd>кортизол</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adolescents</kwd><kwd>cognitive load</kwd><kwd>heart rate variability</kwd><kwd>electrodermal activity</kwd><kwd>cerebral circulation</kwd><kwd>cortisol</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">Прудникова Т.А., Поскакалова Т.А.
