“…A decrease in working capacity can be considered a sign of deterioration in the functional state [ 38 ]. The working capacity dynamics allow one to see at what psycho-physiological “cost” a particular result of an activity is achieved and, in general, to assess whether an activity corresponds to a specialist’s capabilities [ 39 ].…”

(1) Background: The vitamin D level in blood is one of the markers of the functional reserves of the human body and can contribute to more successful adaptation in the Arctic. (2) Methods: The study involved 38 participants in the project “Arctic Floating University—2021”. The determination of vitamin D content was carried out at the beginning of the expedition. A dynamic study was carried out for 20 days in the morning and in the evening. The functional state parameters of the participants were assessed using psychophysiological and questionnaire methods. Statistical methods: Mann–Whitney U-test and correlation analysis. (3) Results: It was found that at the beginning of the expedition, the functional state of participants with more severe vitamin D deficiency is characterized by a shorter average duration of RR intervals (p = 0.050) and reduced SDNN values (p = 0.015). The higher the content of vitamin D, the greater increase in speed (r = 0.510), the higher the increase in projective performance (r = 0.485), and the smaller the increase in projective stress (r = −0.334). Significant relationships between the subjective characteristics of functional states and the vitamin D of participants have not been established. (4) Conclusion: With an increase in the severity of vitamin D deficiency in the blood, the adaptive capabilities of participants decrease during an expedition to the Arctic.

(1) Background: The issue of human adaptation to the Arctic environmental factors is relevant. The adaptation can be assessed through dynamic monitoring of the functional state of a person during his/her stay there. The vitamin D level in blood is one of the markers of the functional reserves of the human body and can contribute to more successful adaptation in the Arctic. (2) Methods: The study involved 38 participants in the scientific and educational expeditionary project "Arctic Floating University-2021". Blood collection for determination of vitamin D content was carried out at the beginning of the expedition. A dynamic study was carried out for 20 days in the morning and in the evening during a marine scientific expedition to the Arctic. The main parameters of the functional state of the participants were assessed using instrumental psychophysiological, projective and questionnaire methods. Statistical methods: Mann-Whitney U-test, correlation analysis using the Spearman coefficient. (3) Results: It was found that at the beginning of the expedition, the functional state of participants with severe vitamin D deficiency is characterized by a shorter average duration of RR intervals and reduced SDNN values, which may indicate a higher level of regulatory mechanisms tension. The pronounced differences in the nature of the dynamic series of objective and projective working capacity parameters were manifested most clearly. According to the subjective questionnaire characteristics of well-being, activity and mood, no significant features of the participants with vitamin D deficiency were revealed. (4) Conclusion: The participants with vitamin D deficiency in blood are characterized by a reduced adaptive capacity during the expedition to the Arctic.

“…Нейродинамические показатели отражают ФС центральной нервной системы, являются чувствительными индикаторами изменений, которые происходят в организме и значимо влияют на ф изиологические и психические характеристики человека. Устойчивая когнитивная работоспособность, внимание, нервно-психическая выносливость, обусловленные индивидуальным профилем свойств НС индивида, во многом являются определяющими факторами эффективной адаптации детей к процессу обучения в школе [8,9].…”

В статье проведен анализ динамики нейродинамических показателей сенсомоторного реагирования детей младшего школьного возраста с ортофорией и гетеротропией после курса консервативного лечения. Проведено обследование 42 детей (84 глаза) в возрасте от 6 до 11 лет, из которых сформированы две группы. В 1-ю группу вошли 14 детей (28 глаз) с ортофорией на фоне гиперметропии средней степени Hm 4,1 (0,75; 9,75) дптр, 2-ю группу составили дети с содружественным сходящимся косоглазием на фоне гиперметропии средней степени Hm 4,6 (0,75; 10,25) дптр – 28 пациентов (56 глаз). Для изучения свойств нервной системы (НС) использовался аппаратно-программный комплекс «НС-Психотест». Были определены нейродинамические показатели сенсомоторного реагирования по методикам «Простая зрительно-моторная реакция» (ПЗМР), «Реакция различения» (РР), «Реакция выбора» (РВ), «Реакция на движущийся объект» (РДО), «Критическая частота слияния мельканий» (КЧСМ). Нейродинамические показатели сенсомоторного реагирования являются объективными критериями текущего функционального состояния нервной системы детей младшего школьного возраста: наличие содружественного косоглазия у детей 2-й группы достоверно приводит к увеличению времени ПЗМР, РР и РВ на 84,8 мс, 49,2 и 58,1 мс соответственно (р<0,05), а также является причиной изменения зрительной экстраполяции (положительное значение показателя времени РДО Ме 117 [79; 212] мс) (р<0,05) и достоверного уменьшения средних показателей теста КЧСМ (Ме 32,2 [31,4; 34] Гц). После курса консервативного лечения нейродинамические показатели ПЗМР, РВ и РДО в 1-й группе детей достоверно улучшились (р<0,05) (на 18%, 10%, 74% соответственно), во 2-й группе детей достоверно значимое улучшение показателей было следующим: ПЗМР на 33% (р<0,05), РР − 24% (р<0,05), РВ − 19% (р<0,05), РДО − 113% (р<0,05) и КЧСМ на 18% от исходного (р<0,05). In the article, we analyzed the dynamics of neurodynamic parameters of sensorimotor response in children of primary school age with orthophoria and heterotropia after a course of conservative treatment. We examined 42 children (84 eyes), aged 6 to 11 years, of which 2 groups were formed. Group 1 included 14 children (28 eyes) with orthophoria against the background of moderate hypermetropia Hm 4.1 (0.75; 9.75) Dptr, the 2nd group consisted of children with concomitant convergent strabismus against the background of moderate hypermetropia Hm 4.6 (0.75; 10.25) Diopter – 28 patients (56 eyes). To study the properties of the nervous system (NS), we used the NS-Psychotest hardware and software complex. Neurodynamic indicators of sensorimotor response were determined according to the methods "Simple visual-motor reaction" (SVMR), "Discrimination reaction" (RD), "Choice reaction" (CR), "Reaction to a moving object" (RMO), "Critical flicker fusion frequency "(CFF). After a course of conservative treatment, the neurodynamic parameters of SVMR, CR and RMO in the 1st group of children significantly improved (p<0.05) (by 18%, 10%, 74%, respectively), in the 2nd group of children, a significantly significant improvement in the parameters was as follows: 33% (p<0.05), RD – 24% (p<0.05), CR – 19% (p<0.05), RMO – 113% (p<0.05) and CFF by 18% from the original (p<0.05).
