The purpose of the study was to investigate the peculiarities of changes in the general functional condition of the brain of highly qualified female athletes specializing in karate, in terms of omega potential indicators and to assess the adaptive capability of the central nervous system during physical load. Materials and methods. The study involved 14 highly qualified female athletes aged 17-22 years – representatives of the Odessa Regional Karate Federation. Determination of the dynamics of infraslow bioelectrical processes of the brain, namely omegapotential, was carried out according to the method of O. G. Sychov et al. (1980) at rest, after performing a test in one squat, with dosed physical load in a closed cycle (with reverse) and during the recovery period after exercise. Results and discussion. According to the results of anthropometric and physiometric measurements, the height of the studied girls specializing in karate, on average, was 164.43±0.86 cm, and body weight – 56.36±2.23 kg. The thorax circumference at rest was 84.86±1.57 cm, at the inhale – 89.57±1.49 cm, at the exhale – 82.5±1.57 cm. The average value of vital capacity of the lungs was 3457.14±101.93 ml, wrist dynamometry – 23.36±1.02 kg, back dynamometry – 63.57±3.53 kg. The analysis of the results of the study of infraslow brain processes showed that in the initial state the omega potential value ranged from 10 to 59 mV, which indicated the optimal baseline level in most female athletes before exercise. In the state of relative rest, the average omega potential values (21-40 mV) were found in 79% of the surveyed girls, high (41-60 mV) and low (up to 20 mV) – in 14% and 7%, respectively. The results of study of omega potential dynamics when tested in one squat indicate isolated cases of adequate responses and optimal activation of adaptive systems of the body to the functional load. In most female athletes, the violation of chemo-metabolic, neurohumoral and hormonal processes were observed after performing the test of one squat. The peculiarities of omega-potential dynamics, which were noted during the performance of dosed physical load in a closed cycle (with reverse), indicate a gradual decrease in the studied indicators relative to the initial state during the performance of bicycle ergometric load, especially during the period of reverse (heart rate = 150-155 beats / min) and at the end of testing. At the same time, the depth of shifts also increased, which reflects the significant tension on the central nervous system and other body systems of female athletes in response to physical load. After performing exercise at the 2nd and 5th minutes of rest, no recovery of infraslow bioelectrical processes to the initial level was recorded, which indicates the development of overstrain of adaptive mechanisms. Conclusion. Testing of qualified female athletes specializing in karate, using a functional test conducted in one squat, according to the data of average group indicators of omega potential revealed a violation of chemo-metabolic, neurohumoral and hormonal processes. The study of individual data shows that in most of the surveyed there are various violations of these body systems. The dynamics of infraslow bioelectrical processes in the brain of female athletes during testing using bicycle ergometric load in a closed cycle (with reverse) is characterized by a steady decrease in omega potential throughout the test, which reflects the overstrain of regulatory mechanisms and deep mobilization of functional capabilities. The restoration of the level of omega potential to the initial level at the 5th minute of the post-exercise period does not occur

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.

Стрімка зміна умов життя сучасної людини, погіршення екологічної ситуації впливає на сталість показників, які отримуються емпіричним шляхом у лабораторних умовах під час дослідження різних представників рослинного світую. Для цього необхідні знання щодо класифікації пряно-ароматичних рослин, які не одне десятиліття широко застосовуються у повсякденному житті, відомостей стосовно біохімічного складу таособливостей їх використання. Тим самим відзначається необхідність підвищення зв’язку теоретичних знань із біології з їх практичним застосуванням. Знання основних біологічних особливостей рослин, зокрема, лікарських, їх біохімічних характеристик, уміння використовувати ці знання у практичній діяльності, а також здатність до прогнозування – один із елементів підґрунтя, на якому базується успішна майбутняпрофесійна діяльність. Дослідження спрямоване на пошук комплексу засобів і умов формування у студентів – майбутніх біологів – практичних навичок самостійного вирішення завдань стосовно вибору та використання біоматеріалу. Проблема полягає в тому, що не зважаючи на однакову методику навчання і лабораторні умови, результати досліджень майбутніх фахівців відрізняються. Встановлення достовірності результату передбачало визначення системності появи похибок, порушення вимог, схожості за внутрішніми та зовнішніми характеристиками біоматеріалу тощо. Вперше введені критерії оцінювання процесуальних дій під час проведення досліджень в лабораторних умовах навчання, що було взято за основу в розробленні нової методики. Представлено методику навчання, в якій відображено сутність творчого підходу до отримання власних наукових результатів під час освітнього процесу в закладі вищої освіти. Запропонована методика спрямована на розширення обсягу теоретичних знань, синтезу їх для втілення у процес цілеспрямованої практичної роботи, формування умінь визначати новизну, швидко виконувати процесуальні дії, розвивати творче самовиявлення.

Analyzing spatial, temporary, and strength characteristics of movements in 7-10-year-old children by using a graphoanalytical method during the reverse exercise test has indicated that overstrain occurs in all units of the structures that ensure formation and implementation of a transitional process. There are increases in regulation errors by 33%, regulation time by 21.5%, system variability by 16%, regulation stability by 19%. The variability of the system is beyond three fluctuations, which is an indicator of full transition of the movement control system in unreliability and instability. The investigations have demonstrated that the reverse exercise procedure is adequate to age-related features of children and may be useful in studying different functional systems. The graphoanalytical method of quantitative assessment of the functional status of the locomotor apparatus is of rather informative value and can be used in the professional activities of a teacher and trainer for personal assessment of the movement control system in children of different age.

Adaptative cardiovascular responses were examined in 15-16-year-old girls during exercises and higher motivation. The latter promotes the optimization, rationalization, and effectiveness of cardiac performance and the mobilization of the body's functional reserves.

Assessment of child's hand movement coordination was made with the help of Mir Lopets method. Movement reaction of three types was determined during exercise. Study results can be used for development of child's abilities.
