It is widely assumed that wrestling is a sport posing high requirements as regards one’s physical qualities strength and endurance. A lot of specialists, however, point out the necessity of harmonious and balanced development of all motor qualities, including flexibility. This research is aimed at wrestlers’ physical preparation and more specifically the dynamics in the physical quality flexibility. We attempted to find out whether altitude influences the manifestation of the physical quality flexibility and to what extent. The research was done among 13 wrestlers from Bulgarian National team, Greco-Roman style, men. We measured the flexibility of the spinal cord and coxofemoral joint during training camps held at low and high altitude. The tests used (Т1, Т2, Т3 and Т4) are easy to be applied. The results were processed statistically and further discussed. It is clear that there were statistically significant differences only along T2, and there was no reliable difference in the results along the rest of the tests - Т1, Т3 and Т4 at a low and high altitude.

На сегодняшний день имеет место противоречие между большим объемом эмпирического и статистического материала по достижениям чувашских спортсменов в крупнейших международных соревнованиях и недостаточно глубоким их анализом, лежащим в основе выявления закономерностей и перспектив развития спорта в республике. Целью исследования является выявление динамики и закономерностей участия спортсменов Чувашской Республики в составе сборной команды страны на Олимпийских играх 1952-2016 гг. Методы исследования: теоретический анализ исторической и справочной литературы по теме исследования, анализ документальных материалов, методы математической статистики. В советский период наибольшее число участников Олимпийских игр среди спортсменов Чувашской Республики (по 4 человека) приходится на игры 1972 и 1976 гг. Самыми успешными можно признать выступления спортсменов Чувашской Республики на Олимпийских играх 1968, 1976 и 1980 гг. Наиболее высокое среднее место приходится на бокс, фехтование, командную велогонку, борьбу классическую. В постсоветский период представительство спортсменов Чувашской Республики в составе Олимпийской сборной России заметно увеличилось и составило по 10 человек на играх в 2000 и 2004 гг., 9 человек на играх в 2008 г. Можно выделить 20-летний период успешного выступления спортсменов Чувашской Республики на Олимпийских играх - с 1992 по 2012 гг. Наиболее высокое среднее место приходится на спортивную гимнастику, бег 3000 м с препятствиями. Today, there is a contradiction between a large volume of empirical and statistical material on the achievements of athletes of the Chuvash Republic in major international competitions and insufficient analysis, which is the basis for identifying the regularities and prospects for the development of sports in the republic. The aim of the study is to identify the dynamics and patterns of participation of athletes of the Chuvash Republic in the national team at the Olympic Games of 1952-2016. The research methods are theoretical analysis of historical and reference literature on the research topic, analysis of documentary materials, methods of mathematical statistics. In the Soviet period, the largest number of participants in the Olympic Games among athletes of the Chuvash Republic (4 people) was in the 1972 and 1976 Games. The performances of the Chuvash athletes at the Olympic Games of 1968, 1976 and 1980 can be considered the most successful. The most striking results were achieved in boxing, fencing, team cycling, and Greco-Roman wrestling. In the post-Soviet period, the representation of athletes of the Chuvash Republic in the Russian Olympic team has noticeably increased and amounted to 10 people at the games in 2000 and 2004, 9 people - at the games in 2008. A 20-year period from 1992 to 2012 can be considered most successful. The greatest results were achieved in gymnastics and steeplechase.

Located on the high altitude slopes in China's mountainous southwestern hinterlands, the Nuosu (Yi) have long been characterized by ethnologists in China as a slave society. In this essay I explore the appropriateness of the label with reference to the distinction, associated with the classicist Moses Finley in his studies of Greco-Roman society, between slave societies and societies with slaves (Finley 1983, 79–83). But my main purpose in focusing on Nuosu slavery, as we know it from the first half of the twentieth century, is to gain a better understanding of Nuosu identity. It makes sense to me that the process by which outsiders, that is, slaves brought in as captives, became insiders reveals a great deal about the constructs of the Nuosu ideology of common origins and identity and about how this transformation from alien to native worked in practice among people historically “remarkably resistant to acculturation,”with boundaries that remain to this day sharp, clear, and relatively impenetrable (Harrell 1995, 101, 104).

Purpose: to analyze the performances of the national Greco-Roman wrestling team of Ukraine at cadet and junior competitions from 1993 to the present. Material and methods. The research used the following methods: analysis of scientific and methodological information and Internet sources; analysis of the official protocols of the competition; retrospective analysis; methods of mathematical statistics. The performances of the athletes of the Greco-Roman wrestling national team of Ukraine at the European and world championships among cadets and juniors from 1993 to the present are analyzed. The number of participants, the number of medals earned, and the number of gold medals were counted. Results: based on the analysis of scientific and methodological information and generalization of advanced practical experience, it was found that the problem of analyzing competitive activity in modern sports is one of the most urgent. During the period under review, 209 athletes of the Ukrainian national team took part in the European Championships, of which 13 (6,2 %) became winners of the competition, and 55 (26,3 %) wrestlers took prizes. While 199 wrestlers have taken part in the European Championships among juniors since 1993, 71 (35,7 %) medals were won, of which 19 (9,5 %) were gold. In the period under review, 136 athletes took part in the world championships among cadets, and 12 (8,8 %) gold medals were won. Making comparisons, 192 athletes of the Ukrainian national team took part in the world championships among juniors, 10 (5,2 %) gold and 41 (21,4 %) medals in general were won. The analysis of the results showed that the largest number of athletes took the second, the third and the fifth places (more than 30 wrestlers for each place) at international competitions among cadets. The largest number of Greco-Roman style junior wrestlers of the Ukrainian national team took the following places: the third place (46 wrestlers), the fifth place (40 wrestlers) and the second place (37 wrestlers). Conclusions. The athletes of the Ukrainian national team show good results and occupy high places, however, there is a negative trend towards a decrease in the number of awards over time. Keywords: Greco-Roman wrestling, competitive activity, cadets, juniors, analysis.

The article presents the analysis of the peculiarities of the selection systems for athletes-candidates to the Ukrainian national team for participation in the Olympic Games (on the example of combat sports). The urgency of the work is due to the need to develop and implement a modern model of Olympic training in combat sports, which would allow the athletes to compete successfully in the international arena. The purpose of the study was to determine the features of the current selection systems for athletes-candidates to the Ukrainian national team to participate in the Olympic Games (on the example of combat sports). Material and methods. Theoretical analysis, generalization of literature and Internet data, documentary method allowed to identify trends in modern Olympic combat sports and analyze the selection systems governing the inclusion of Ukrainian athletes in the starting lineup of participants in the Olympic Games in modern combat sports (fencing, boxing, Free and Greco-Roman wrestling, judo, taekwondo, karate). Results and discussion. Most of the provisions of the selection systems for athletes-candidates to the Ukrainian national team to participate in the Olympic Games are similar. In most combat sports, selection is based on an analysis of the performances of athletes in national and international competitions, competitiveness and the results of personal fights with major rivals who will participate in the Olympic Games. Selection for the starting lineup of the team at the main competitions of the season or four-year Olympic cycle consists of several stages, each of which determines a different number of athletes-candidates for the national team. As the year of the next Olympic Games approaches, the number of candidates is decreasing proportionally. The peculiarity of all systems of national selection in modern Olympic combat sports is that the athlete needs to realize his (her) potential in almost every competition during the annual macrocycle, as it depends on the prospect of his inclusion in the starting lineup of the national team at major competitions. Taking into account the fact that the body's adaptive capabilities are limited, it is important to determine the appropriateness of the athlete's performance in a particular tournament, taking into account his (her) position in national and world rankings, and other conditions governing its inclusion in the starting lineup. Conclusion. Differences in the selection systems are the mechanisms for determining the starting lineups of the team in the main competitions of the season or four-year Olympic cycle (demonstration of a certain result or winning a place in a particular tournament, position in the world rankings, obtaining an Olympic license)

The results of a study of the autonomous regulation of the heart rate in elite wrestlers with different dominance of the cerebral hemispheres were present in the manuscript 23 elite wrestlers. Were examined members of the National Team of Ukraine in Greco-Roman wrestling, aged 22-34 years-old. A body composition monitor "Omron BF511" and a computer electrocardiograph "Fazagraf" were used. It was revealed that elite wrestlers with a dominance of the right hemisphere have more intense regulation of the heart rhythm compared to wrestlers with a dominance of the left hemisphere of the brain. With an increase in the tension of the system of autonomous regulation of the heart rhythm in wrestlers with the dominance of the right hemisphere of the brain, the activation of the central and sympathetic division of regulation occurs. For the purpose of a more effective preparation process and in the development of individual training programs for elite wrestlers, it is necessary to determine the dominance of the cerebral hemispheres.

Abstract Background Acute mountain sickness (AMS) is a cluster of symptoms that commonly occur in those ascending to high altitudes. Symptoms can include headaches, nausea, insomnia and fatigue. Exposure to high altitude can also lead to high-altitude cerebral oedema (HACE), which is a potential cause of death whilst mountaineering. Generally, AMS precedes the development of HACE. Historical studies have demonstrated the effectiveness of regular dexamethasone administration in reducing the symptoms of AMS. However, the mechanism by which dexamethasone works to reduce symptoms AMS remains poorly understood. Further studies, simulating altitude using hypoxic tents, have characterised the effect of prolonged exposure to normobaric hypoxia on cerebral oedema and blood flow using MRI. This randomised trial assesses the effect of dexamethasone on hypoxia-induced cerebral oedema in healthy adult volunteers. Methods/design D4H is a double-blind placebo-controlled randomised trial assessing the effect of dexamethasone on hypoxia-induced cerebral oedema. In total, 20 volunteers were randomised in pairs to receive either 8.25 mg dexamethasone or normal saline placebo intravenously after 8 h of hypoxia with an FiO2 of 12%. Serial MRI images of the brain and spinal cord were obtained at hours 0, 7, 11, 22 and 26 of the study along with serum and urinary markers to correlate with the severity of cerebral oedema and the effect of the intervention. Discussion MRI has been used to identify changes in cerebral vasculature in the development of AMS and HACE. Dexamethasone is effective at reducing the symptoms of AMS; however, the mechanism of this effect is unknown. If this study demonstrates a clear objective benefit of dexamethasone in this setting, future studies may be able to demonstrate that dexamethasone is an effective therapy for oedema associated with brain and spinal cord ischaemia beyond AMS.

Technical-tactical and physiological demand analyses of wrestling combats are important because they reveal essential information for the development of contextual training and specific physical preparation of wrestlers. Therefore, the aim of this review is to describe the characteristics of wrestling combats in freestyle, female and Greco-roman styles. The time-motion analysis presented in this article is the main component to carry out inferences on intensity and effort: pause ratio of combat actions. After rules modification in 2013, wrestling combats showed quicker and more diversified actions, especially in the lighter categories. For Greco-roman wrestling, most studies showed <em>takedowns</em> as the most effective techniques in World competitions for the period 2009-2011. For the same period, foot/leg techniques were the most effective in female and freestyle wrestling, followed by <em>takedown</em> attacks. Recent analyses, developed after 2013 rules modification, showed that the decisive offensive actions were applied on foot and in <em>par terre</em> situations – especially <em>gutwrenches</em> techniques and derivatives of <em>suplex</em> movements. The knowledge on the determinant and predominant actions of wrestling combats can be applied in future research, as well as can be used practically for training, physical preparation and assessments of similar combat actions. It also allows interventions to prevent injuries resulting from technical and tactical wrestling actions.
