Abstract:
The problem of biorhythms is one of the most important problems of our time, since the violation of the rhythmic activity of both the body as a whole and its individual organs and systems is of great importance not only for physiology, medicine and valeology, but also for other social and economic processes in modern society. The purpose of the study: to improve the methodology for planning the training process for powerlifting athletes, taking into account their biorhythms. Research methods: analysis of scientific and methodological literature, determination of biorhythms using a computer version, testing taking into account biorhythms, pedagogical experiment and methods of mathematical statistics. The experiment involved 16 qualified athletes aged 16–17 years. As a result of the study, it was revealed that the athletes of the experimental group, who used biorhythm calculations in planning the training load, improved strength indicators by 7,2%, in contrast to the control group, who trained without taking into account the calculation of biorhythms and improved strength results - by 4,6%. Athletes have also been found to exhibit biorhythmic addiction to a greater or lesser extent. It has been established that planning the training process taking into account biorhythms has a positive effect on the result to a greater extent than planning the same load without taking biorhythms into account. The analysis of literary sources showed that the use of biorhythmology data and the use of biological rhythms in planning training loads is not widely used in sports practice today. In the course of the statistical analysis of experimental data, it was found that planning the training process taking into account biorhythms positively affects the result to a greater extent than planning the same load without taking into account biorhythms (р<0,05).

Abstract:
The state of temporal organization of hemostasis system (HS) and microcirculation (MC) was studied in 72 rats of Wistar line weighted 200-250 gr. They were in 8 groups: intact rats, rats with physiologic pregnancy; with experimental gestosis; prophylactic and treatment-and-prophylactic injections of complex phytoadaptogens – phytococktails “Biorhythm-E” and “Biorhythm-RG”. The analysis of coagulation and microcirculation indices was performed on the 21-st day of gestation. The biorhythms were estimated with the help of “cosinor-analysis” programmer. The reliable ultradian biorhythms prevailed in the intact rats, among which there were rhythms (5%) with high and middle amplitude, with the period of 5-7 hours. The chronic intersystemic pathologic desynchronosis developed while the experimental gestosis. The usage of phytococktail “Biorhythm-E” was more effective while the architectonics of temporal organization impairment at the expense of the part of the reliable circadian rhythms increase while the treatment-and-prophylactic administration. The usage of complex phytoadaptogens promoted the increase of HS and MC adaptation resources, normalizing the impaired architectonics of biological rhythms.

Abstract:
Aim: To analyze the relationship between daily blood pressure biorhythms and left ventricular myocardial hypertrophy in working-age men with arterial hypertension. Materials and Methods: Fifty-seven men with AH (mean age: 44.6±1.3 years) underwent Echo-CG and daily ABPM. Non-dipper and night-peaker patterns indicated BP biorhythm disturbances, while normal dipper and over-dipper patterns indicated undisturbed BP biorhythms. LVH was defined as LMMI > 115 g/m^2. Results: About 60% of participants exhibited diurnal BP rhythm disorders, with a higher prevalence of LVH in this group compared to those with normal BP biorhythms (32% vs. 22%, p>0,05). Patients with normal daily BP biorhythms had significantly higher circadian indices of HR, systolic and diastolic BP, and double product compared to those with disturbed BP rhythms. Conclusions: In young men with “non-dipper” and “night-peaker” patterns, LVH appears to be more pronounced than in those with normal daily BP biorhythms. This approach may optimize the timing of antihypertensive drug administration.

Abstract:
Biorhythm or circadian rhythm represents a biological process through which the human body adopts a rhythmicity, which can be measured once every 24 hours. An analytical analysis of human biorhythms and their interaction in the synergy of psychomotor capabilities of lawn tennis players was performed. The reliability of performances in official competitions is conditioned by the integral preparation of the athlete, the components of which are optimal technical and tactical, physical, functional and mental training, taking into account the manifestation of his biorhythms. Biorhythmology is currently of great theoretical and practical importance in sports training. However, certain principles and provisions of biorhythmology in sports are insufficiently highlighted and scientifically justified, but, without a doubt, research in this direction gives the expected practical result. A series of aspects of psychophysiology are highlighted, the solution of which largely depends on the success of using biorhythms to increase the efficiency of sports activities. The dynamics of the circadian rhythms of the psychophysiological functions are reflected in the volume and intensity of the applied training and competition tasks, as well as in the physical recovery after their performance. In order to identify the relationship between biorhythms and sports and psychomotor performances of athletes, we analyzed the results obtained in competitions by tennis students (the best and worst of the season). The analysis of the obtained results showed that the best sports and test results are presented by tennis players during the optimal phases of the biorhythm, and the worst - during critical periods. It is necessary to take into account the characteristics of the biorhythm when predicting and analyzing the performances of athletes in certain competitions and the test parameters that characterize their psychomotor capabilities as determining factors of sports and tactical abilities. It has been established that psychomotor indices and sports performance of tennis players are interconnected with the periods of biorhythms. In the negative period and on the critical days, the greatest decrease in the reactions to the moving object (RMO) was observed, the decrease in the state-impact force, which provides the force of the deep (postural) muscles of the trunk, involved in maintaining both statodynamic and dynamic, one of the factors of motor-coordinating qualities of tennis players.

Abstract:
Individual linear growth rates were studied in freshwater pearl mussels Margaritifera margaritifera from the Livojoki River. Growth deceleration coefficients were shown to vary widely and differ significantly among individuals. The average value of the growth deceleration coefficient for the population is 0.060. The growth of mussels in the Livojoki River is accompanied by two regular biorhythms. These biorhythm periods were roughly constant both through an individual's ontogeny and among mussels, their average periods were 7.16 and 4.09 years. We discuss the possibility that these biorhythms are of thermodynamic nature.

Abstract:
This study aimed to implement the researcher's biorhythm graph using a programing language called Python in relation to trigonometric functions. The etymology of biorhythm is a combination of two Greek words, Bio, which means life, and Rhythm, which means regular and accurate rhythm, and means the rules of human life rhythm. In other words, the biorhythm is a theory that everyone is governed by three rhythm curves called physical rhythm, emotional rhythm, and intellectual rhythm that start inside the body from birth to death. During this study, biorhythm and trigonometric functions were studied, and biorhythm graphs were implemented with trigonometric functions when the researcher's date of birth was entered through Python. A biorhythm graph was implemented based on Python, the most used programming language. The Python syntax used in the algorithm is typically a sympy function, a datetime function, arrange function, and a function. The value obtained after implementing the algorithm using this grammar is as follows. This is the result of implementing a biorhythm graph using the algorithm implemented by the two researchers. This paper can be used in various fields related to the relationship between biorhythms and trigonometric functions.

Abstract:
Zusammenfassung Hintergrund und Zielsetzung Viele Arbeitszeitregelungen greifen in den Biorhythmus der Beschäftigten ein und wirken sich negativ auf Konzentration und Schlafqualität aus. Schichtarbeitende leiden doppelt so häufig an Schlafstörungen wie andere Erwerbstätige. Schlafmangel und gestörter Schlaf erhöhen das Unfallrisiko. In dieser Studie wurde untersucht, ob die Schlafdauer von der Lage der Arbeitszeit und vom individuellen Chronotyp beeinflusst wird. Methode In einer Querschnittsuntersuchung wurden 374 Beschäftigte mit meldepflichtigem Arbeitsunfall zu ihrem Chronotyp und ihren üblichen Schlafenszeiten befragt. Zur Chronotypermittlung wurde die Composite Scale of Morningness (CSM) in der deutschsprachigen Version verwendet. Die Effekte von Schichtarbeit, Chronotyp und Alter auf die Schlafdauer wurden mittels multivariabler linearer bzw. logistischer Regression untersucht. Ergebnisse Ohne Schichtarbeit (Tagarbeitszeiten [TA]) betrug die durchschnittliche Schlafdauer an Arbeitstagen 7,2 h (SD 0,9). Vor einer Frühschicht (FS) war die Schlafdauer verkürzt auf 6,4 h (SD 0,6). Ein früher Arbeitsbeginn ist ein Risikofaktor für eine kurze Schlafdauer (<7 h) vor FS Odds Ratio (OR) = 13,8 (95 % Konfidenzintervall [KI] 3,38–56,25) im Vergleich zu einem späten Arbeitsbeginn (Spätschicht). Ein später Chronotyp erhöht ebenfalls das Risiko für kurze Schlafdauer an Arbeitstagen OR = 2,7 (95 % KI 0,97–7,67). An arbeitsfreien Tagen haben Frühtypen eine signifikant kürzere Schlafdauer als Intermediärtypen OR = 2,2 (95 % KI 1,16–4,31). Diskussion Ein späterer und flexibler Arbeitsbeginn unter Einbeziehung des Chronotyps sowie Maßnahmen für gesundheitsförderlichen Schlaf könnten dazu beitragen, müdigkeitsbedingte Arbeitsunfälle zu verhindern.

Abstract:
The article is devoted to the study of ways to optimize the training process for student basketball, volleyball and futsal teams, taking into account the individual biorhythmic properties of female athletes. The study determines the importance of individualizing training and preparation, in particular, taking into account circadian rhythms and other biorhythmic aspects that determine physiological and psychological changes in female athletes during the day. The tasks of the study included testing the biological rhythms of female athletes to improve the training process. 36 sportswomen (14 basketball players, 12 volleyball players, 10 soccer players) of the teams of the National University of Life and Environmental Sciences of Ukraine took part in the study. The analysis of the biological rhythms of female athletes included various indicators that help to understand their physiological reactions and determine the optimal schedule of training and rest. Among them were taken: heart rate, rhythmic changes in body temperature (measurement of body temperature during the day to determine the circadian rhythm of heat exchange), rhythmic changes in blood pressure (observation of changes in blood pressure during the day to determine the circadian rhythm of cardiovascular activity), indicators of activity and sleep (determination of activity and sleep mode, including time of awakening, time of falling asleep and duration of sleep), hand strength (hand dynamometry), standing long jump. The article examines the results of the study, which include an analysis of the optimal time for training, fatigue and recovery management, adaptation of training programs to biorhythms, and the impact on psychological readiness. The conclusions drawn indicate that an individual approach to training, based on biorhythmic properties and psychomotor qualities, can improve the performance of sportswomen in the aforementioned teams. This article is aimed at coaches, scientists and physical training specialists interested in innovative methods of training female athletes aimed at taking into account their individual biorhythms to achieve optimal results in basketball, volleyball and futsal.

Abstract:
Differences in Drosophila courtship song components are considered to play an important role in species sexual isolation, because of the observed lack of variation within individuals of a species, and the relatively large differences between closely related species. When a male courts a female, a song is produced, usually consisting of a hum song and trains of pulses. Song recordings from the 8 members of the D. melanogaster subgroup, as well as from several types of interspecific hybrid crosses reveal that the Interpulse Intervals (IPIs) oscillate rhythmically about their mean, in a species-specific fashion, as courtship progresses. Various other song components, such as Intrapulse Frequency (IPF), Sine Song Frequency (SSF), Cycles per Pulses (CPP), Mean Burst Duration (MBD), and Mean Interburst Interval (MIBI) which are also thought to contribute to the maintenance of species-specific differences, thus sustaining species barriers were also studied in different species. Hybridisation between species gave evidence for possible X-linked factors in song rhythms, but generally, autosomal factors appear to be involved in controlling the other song characters. Another behavioural trait that may contribute to the species isolation of the members of the melanogaster subgroup are the circadian locomotor activity patterns. Locomotor activity profiles in constant darkness conditions revealed species-specific differences between the species in the period of their circadian oscillator, while locomotor activity profiles in light/dark cycles demonstrated phenotypic differences between the various species of the melanogaster subgroup. Hybridisations were used to assess the relative contribution of maternal and paternal factors. The overall species pattern of activity appeared to be determined by the sex-chromosomes, whereas other characteristics were primarily autosomally controlled. The implication of these findings on song and circadian behavioural cycles with respect to the current molecular analysis of circadian clock genes is discussed.

Abstract:
Background. Fibromyalgia (FM) is a chronic syndrome, characterized by lasting and diffuse chronic musculoskeletal pain. It is defined as a “central sensitization syndrome”, characterized by an increased sensitivity in the central nervous system to several stimuli. Some psychological factors worse or facilitate the adaptation and pain management in FM. In order to provide a rationale to implement further psychological and psycho-educational interventions to reduce FM impact, improving pain severity and quality of life (QOL), the aims of the present study was: 1) to verify the role of high alexithymia and low sense of coherence (SOC) as determinants (risk factors) for a severe FM impact, severe pain (current and in the last week), severe pain impact and poor QOL; 2) to evaluate the associations between the dysregulation of biological and social rhythms (eating, sleeping, daily life and social activities), FM impact, pain severity (current and in the last week), pain impact and QOL. Methods: Correlational, case-control study. 50 women with FM were assessed with FIQ (FM impact), FIQ “pain” item (pain severity in the last week), (VAS (current pain severity), TAS-20 (alexithymia), SOC (sense of coherence), SF-12 (QOL), SF-12 “pain” item (pain impact), BRIAN (biological rhythms). Results: FM impact, related pain and QOL were negatively correlated with SOC (p<0.01), positively with alexithymia (p<0.05) and dysregulation of biorhythms (p<0.01). Furthermore, subject with high alexithymia and low sense of coherence (risk factors) were more likely to have severe FM impact, severe pain in the last week and poor QOL (p<0.05) after controlling for potential confounders such as age, marital status, education level, occupation. Conclusions: psychological factors, such as alexithymia and sense of coherence, as well as behavioral factors, such as those implied in the regulation of biological and social rhythm,s play a significant role in FM impact, pain perception and QOL. Further studies are needed to point out the efficacy of psychological interventions on pain management and QOL of people with FM.

Дисертація присвячена розв'язанню актуальній проблеми сучасної патологічної фізіології – особливостям синтезу епіфізарного та екстрапінеального мелатоніну та обґрунтуванню його ролі в гормональних та імунних механізмах виразкової хвороби шлунка у щурів різної статі та віку. Встановлено циркануальний ритм секреції мелатоніну в щурів обох статей різного віку та циркануальний ритм секреції тестостерону в щурів-самців усіх вікових групах. Визначено, що на тлі світлового десинхронозу, виразкового ураження шлунка та поєднанні десинхронозу та виразкового ураження шлунка, відбувається достовірне зниження вмісту мелатоніну в сироватці крові щурів обох статей усіх вікових груп, а особливо у щурів-самців віком 9 міс. Під впливом різних патологічних станів рівень тестостерону в крові навпаки підвищується у щурів усіх вікових груп різної статі при максимальному рівні тестостерону в щурів-самців віком 9 та 15 міс щодо інтактного контролю. Найсильніший негативний зворотній кореляційний зв’язок між рівнями мелатоніну і тестостерону виявлено у 9- та 15-місячних самців в осінній період та при всіх патологічних станах. Визначено, що мелатонін-продукуючи клітини шлунка морфологічно представлені трьома типами клітин та переважно знаходяться у фундальному відділі органа. Незалежно від статі їхня кількість восени менша, ніж узимку, при цьому у самців їх значно менше, ніж у самок в обидва сезони. Десинхроноз, виразкове ураження шлунка та їх поєднання призводить до статистично достовірного зменшення загальної кількості мелатонін-продукуючих клітин як у самців, так і у самок. Найбільше зниження цього показника виявили у групах самців 9- та 15-місячного віку. Проведено дослідження показників імунної системі та окислювального гемостазу при пошкодженні різних джерел синтезу мелатоніну та обґрунтована схема лікування виразкової хвороби з додаванням до стандартної терапії екзогенного мелатоніну.
Диссертация посвящена решению актуальной проблемы современной патологической физиологии – особенностям синтеза эпифизарного и экстрапинеального мелатонина и обоснованию его роли в гормональных и иммунных механизмах язвенной болезни желудка у крыс разного пола и возраста. Установлен цирканнуальний ритм секреции мелатонина у крыс разного пола и возраста и цирканнуальний ритм секреции тестостерона у крыс-самцов во всех возрастных группах. Определено, что на фоне светового десинхроноза, язвенного поражения желудка и сочетании десинхроноза и язвенного поражения желудка, происходит достоверное снижение мелатонина в сыворотке крови крыс обоего пола всех возрастов, а особенно, у крыс-самцов в возрасте 9 мес. Под влиянием различных патологических состояний уровень тестостерона в крови наоборот повышается у крыс всех возрастных групп разного пола при максимальном уровне тестостерона у крыс-самцов в возрасте 9 и 15 мес по отношению к интактному контролю. Очень сильная обратная корреляционная связь между уровнями мелатонина и тестостерона определена у 9- и 15-месячных самцов в осенний период и при всех патологических состояниях. Установлено, что мелатонин-продуцирующие клетки желудка морфологично представлены тремя типами клеток и преимущественно находятся в фундальном отделе органа. Независимо от пола их количество осенью меньше, чем зимой, при этом у самцов значительно меньше, чем у самок в оба сезона. Десинхроноз, язвенное поражение желудка и их сочетание приводят к статистически достоверному уменьшению общего количества мелатонин-продуцирующих клеток как у самцов, так и у самок. Наибольшее снижение этого показателя определено в группах самцов 9- и 15-месячного возраста. Проведено исследование показателей иммунной системы и окислительного гемостаза при повреждении различных источников синтеза мелатонина и обоснована схема лечения язвенной болезни с добавлением к стандартной терапии экзогенного мелатонина.
The thesis is devoted to the solution of the actual problem of modern pathological physiology – the peculiarities of the synthesis of epiphyseal and ekstrapineal melatonin and substantiation of its role in the hormonal and immune mechanisms of gastric ulcer in rats of different sex and age. By the results of the study the circannual rhythms of secretion of melatonin in rats of both sexes and all ages with the lowest levels of melatonin in the blood in autumn and spring and the highest content in summer and winter were determined. In all age groups studied the highest level of melatonin in the blood of both males and females in all seasons was determined at age of 3 months, the lowest level was in rats at the age of 20 months. At the same time, the decrease in the content of melatonin was observed in the male active reproductive age of 9 months – 127.28±5.11 pmol/L. It was found that on the background of light desynchronosis there was a significant reduction of the melatonin content in the blood serum in rats of both sexes and all ages. The maximum decrease of melatonin in desynchronosis was found in male rats aged 9 months – by 31 % (p≤0.05), as well as in rats of both sexes aged 20 months – by 23 % in males and 24 % in females (p≤0.05) compared to the intact control. In ulcerative lesions the melatonin levels in the blood serum of all age groups decreased in male rats by 22–43 %, and in female rats by 21–23 % compared to the control (p≤0.05). The greatest reduction of the melatonin level was revealed in male rats aged 9 and 20 months – by 39 % and 43 %, respectively (p≤0.05). The combination of ulcerative lesions of the mucous membrane of the stomach with desynchronosis led to the reduction of the melatonin content in the blood serum in rats of all age groups rats compared to the intact animals, animals with desynchronosis and animals with ulcerative lesions of the gastric mucosa, especially in male rats aged 9 and 15 months. The circannual rhythm of secretion of testosterone in male rats was high in autumn and low in winter in all age groups. In male rats the highest testosterone level was determined in animals aged 9 and 15 months in autumn (7.57±0.53 nmol/l and 6.77±0.48 nmol/l) corresponding to the period of physiological desynchronosis. In light desynchronosis and ulcerative lesions of the gastric mucosa there was a significant increase in the testosterone content in rats of all age groups and sexes at the maximum level of testosterone in male rats aged 9 and 15 months (desynchronosis – 4.81±0.37 nmol/l and 5.09±0.33 nmol/l; ulcerative lesions 5.95±0.76 nmol/l and 5.81±0.40 nmol/l, respectively) (p≤0.05) compared to the intact control. The study of extrapineal source of the melatonin synthesis – melatonin-producing cells of the gastric mucosa – was conducted in rats of different sex and age. It was found that melatonin-positive-labeled cells were located in the basal and middle sections of tubular glands of the gastric mucosa, they were presented by three types of cells and were mainly in the fundic part rather than in the pyloric one. In desynchronosis, ulcerative lesions of the stomach and their simultaneous effects there was a significant reduction in the total amount of melatonin-positive-labeled cells in different parts of the gastric mucosa in rats of different sex and age, the greatest reduction of these cells was observed in the groups of males aged 9 and 15 months. It was found that desynchronosis was a significant factor in the oxidative homeostasis disorder in rats of different age and sex as a result of oxidative stress, especially in male rats aged 9 months. In desynchronosis the levels of TBA-reagents (by 1.3 times) increased reducing the activity of SOD and catalase in the blood (by 1.6 times). Desynchronosis led to changes in the immunological reactivity of the organism, and it was confirmed by the decrease of the percentage of T-lymphocytes in the blood due to T-suppressors (by 1.3 times), and the increase of the level of B-lymphocytes (by 1.2 times). It may indicate intensification of the humoral immune response to antigens of different nature. In ulcerative lesions of the stomach the indicators characterizing subpopulations of blood lymphocytes had the opposite direction: in the total decrease of T-lymphocytes there was an increase of T-suppressors (by 1.2 times) with a decrease in T-helpers (by 1.9 times) and B-lymphocytes (by 2 times), indicating a disorder of both cellular and humoral immunity in the experimental animals. Based on the results of the studies the scheme has been proposed for the relationship between melatonin and testosterone, which explains the pathogenesis of peptic ulcer disease in men aged 29-40 years, and the scheme for treating peptic ulcer with addition of exogenous melatonin to the standard therapy has been substantiated.

Abstract:
This dissertation focuses on monitoring a one year body weight change among adolescent males (15 20 years old) depending on their chronological type. Probands filled in a questionnaire and were divided in two groups ("early birds" and "night owls). Night owls get up later and are more active in the afternoon and in the evening. By contrast, early birds get up earlier and their activity during the afternoon and evening is gradually fading. Theoretical part clarifies key words of study. Practical part explains methods, procedures and aims but mainly results and practical recommendations of the whole dissertation.

Abstract:
Timothy grass began to be used as a fodder crop in the north of the Non-Chernozem zone of Russia more than 400 years ago, most often it was sown together with meadow clover. These two species have quite similar biorhythms of development. Then this culture began to spread widely, first in Europe, and then around the world. The main advantages of Timothy grass are high ecological plasticity, good adaptability to heavy soils, and longevity. Modern varieties are characterized by good resistance to diseases, adverse weather conditions and relatively good quality indicators of the resulting feed.
