Aim: Is to study the role of water in the life of students and to investigate the impact of its quality on the health of students who did sports. Materials and Methods: The study was conducted at Polissya National University (Zhytomyr, Ukraine) in 2018-2020. Thus, 509 students between the ages of 17 and 23 who did not do sports and 317 student-athletes were surveyed. The level of students’ health was examined according to the methodology of G.L. Apanasenko. Results: It was found that the majority of students who did not do sport (97.5% of males and 96.7% of females) did not stick to the water consumption schedule, while 50.8% of males and 52.2% of females who did sport followed strict norms of the water consumption schedule to maintain water balance. According to most health indicators, students-athletes had better average values of the studied indicators than those students did not do sport. Conclusions: Water plays an important role in the lives of students and especially those students who do sport. High-quality water, sticking to water consumption schedule, especially during prolonged physical exercise and at high temperatures have a positive effect on the body and improve the health of students.

Funds collection zebranie funduszy SummaryBackground. The objective of the study was to explore the dynamics of the functional state of the central nervous system (CNS) and neurophysiological processes of girls 16-18 years old in the context of their transition to a new level of social organization. Material and methods. The functional state of the CNS was studied in girls 16-18 years old in a state of relative muscular rest through observation of visible motive reactions, Loskutova's method, and in the fifth minute of renewal after the physical loading with variable power. Results. We found that 17 year-old girls had the best functional CNS capabilities. The reduced adaptive capacity of the CNS in 16 year-old girls is due to their necessity for adaptive reorganization of regulatory mechanisms to new social conditions: examinations and university entry. After physical activity, 16 and 18 year-old girls registered stress reactions, indicating decreased CNS adaptation. Conclusions. 17 year-old girls were observed at rest to have better CNS functionality compared to the other age groups. Analysis of the dynamics of the functional CNS states of 16-18 year-old girls after exercise resulted in the identification of two main reaction types: 1) reduction of the basic criteria at high initial values; 2) increase of criteria of a general functional state of a brain at low raw data. StreszczenieWprowadzenie. Celem pracy było zbadanie zmian funkcjonowania ośrodkowego układu nerwowego oraz specyfiki procesów neurofizjologicznych u dziewcząt w wieku 16-18 lat w wyniku przejścia na nowy poziom organizacji społecznej. Materiał i metody. Stan funkcjonowania ośrodkowego układu nerwowego był badany u dziewcząt w wieku 16-18 lat na podstawie przestojów widocznych reakcji motywacyjnych metodą T. Loskutova w stanie relatywnego odpoczynku mięśniowego i w piątej minucie odnowy po obciążeniu fizycznym o zmiennej mocy. Wyniki. Wyniki badań wykazały, że dziewczęta w wieku 17 lat miały najlepsze możliwości funkcjonalne ośrodkowego układu nerwowego. Zmniejszenie zdolności adaptacyjnych ośrodkowego układu nerwowego u dziewcząt w wieku 16 lat wynika z konieczności reorganizacji i przystosowania mechanizmów regulacyjnych do nowych warunków społecznych: egzaminów i przyjęcia na uniwersytet. Po aktywności fizycznej u dziewcząt w wieku 16 i 18 lat zaobserwowano reakcję stresową, która wskazuje na obniżenie mechanizmów adaptacyjnych ośrodkowego układu nerwowego. Wnioski. U dziewcząt w wieku 17 lat w stanie odpoczynku zaobserwowano lepsze funkcjonowanie ośrodkowego układu nerwowego w porównaniu z innymi grupami wiekowymi. Analiza zmian w stanie funkcjonowania ośrodkowego układu nerwowego u dziewcząt w wieku 16-18 lat...
Purpose: to suggest and to evaluate the criterion score of the physical and psychophysiological condition of students. The basis of the score is the individual-directed pedagogical control at physical education. Material and methods: the study involved students (n = 75, age - 17-19 years). The physical condition was determined by applying anthropometry and motor skills testing. The psychophysiological condition was studied according to objective parameters of psychomotor qualities and functional capabilities of the cardio-respiratory system. Results: It was realized the criterion score of the individual degree of students’ adaptability to physical loads. It was determined the most significant interrelation between the indicators of motor qualities and psychomotor parameters of students. It was revealed the approaches of realization the complex individual-directed pedagogical control in the physical education of students. Conclusions: criteria of physical and psychophysiological capabilities of students are recommended for determining their adaptability to physical loads.
