Purpose: to develop a methodology for improving the technical preparedness of athletes during the transition to pankration from another sport. Materials and methods. The following generally accepted methods were used in the work: analysis of scientific and methodological literature and Internet sources, surveys of qualified specialists - trainers in pankration. Results: based on the analysis of scientific and methodological literature and Internet sources, it was found that pankration includes the technique of various types of martial arts (boxing, kickboxing, Thai boxing, freestyle wrestling, sambo, judo), equally combining wrestling and percussion techniques. Today in our country there is a low level of scientific and methodological support of the training process for modern pankration, while the growing popularity of this sport requires further improvement of methods of training. At the same time, today, as a rule, qualified and highly qualified athletes in pankration are formed from athletes who have moved from another type of martial arts and had different levels of training. With the help of a survey of qualified specialists - coaches, the aspects of the preparation of athletes of other sports during the transition to pankration were revealed. The main features in the preparation of athletes of other sports during the transition to pankration are highlighted: the implementation of protective actions to other sports; performing attacking actions, which allows you to get an early victory in a duel; performing counterattacking actions while performing attacking actions in other sports. Conclusions. Pankration includes techniques of various types of combat sports (boxing, kickboxing, Thai boxing, freestyle wrestling, sambo, judo), equally combining wrestling and impact sports techniques. The developed methods provided for the implementation of exercises of various technical orientation (impact sports and wrestling) in two blocks of exercises. The main means of our methodology for athletes with basic sports, wrestling, were: stances, movements, strikes, running exercises, flexibility exercises and breathing exercises. For athletes whose basic sport was shock, the following exercises were proposed: wrestling stance, movements, throws, sweeps, holds, wrestling in the clinch, wrestling on the ground, passes to the legs, painful holds, suffocation. Keywords: pankration, methods, technique, improvement, various types of martial arts

Mouthrinses have been used for centuries for medicinal and cosmetic purposes, but it is only in recent years that the rationale behind the use of the ingredients has been subject to scientific research and clinical trials. Although Listerine held its position formany years in the vanguard of the anti-plaque agents, the advent of mouthrinses containing chlorhexidine was a major breakthrough in the research for a chemical means to prevent disease. Since that time, and especially in the past ten years, the number of formulations that claim to have anti-plaque, anti-calculus, and anti-caries activity has increased, and much emphasis has been placed on such substances as an adjunct to, or indeed to replace, conventional toothbrushing techniques. This review covers the literature on mouthrinses over the past five years, concentrating more on the anti-plaque, anti-gingivitis, and anti-calculus formulations. In the first section, the methods of conducting clinical trials of mouthrinses are discussed, and a plea is made for a greater degree of standardization of methodology with agreed acceptable levels of clinical benefit. Trials of established mouthrinses are considered, and the advantages and disadvantages of several newer formulations discussed. From the review, it appears that chlorhexidine has no equal in its effects on reduction of plaque and gingivitis, but major drawbacks lie in the taste and stain-producing problems. The pre-brushing rinse, Plax, does not have unqualified success in all trials, though the more recent European formulation may have promise. Newer rinses which inhibit bacterial adhesion to tooth surfaces also appear promising, and it is suggested that more work on combinations of active ingredients is necessary.

The relevance of the research is that current trends in the development of Olympic combat sports require a constant search for ways to improve the tactical skills of athletes of different ages and qualifications. The purpose of the study is to identify and characterize the technologies of tactical training in modern combat sports. Research methods and material. Theoretical analysis, documentary method, generalization of literature data and the Internet allowed us to identify the problematic field of tactical training in martial arts and formulate a research hypothesis. Later, an expert assessment was conducted with the involvement of forty experts in modern Olympic combat sports to determine their attitude to the implementation of tactical training of athletes at various stages of long-term improvement. The generalization of the experts' answers allowed us to determine the tactical training technologies used in the training process of athletes of different experience. Research results. Technologies of tactical training of athletes that can be applied at different levels (general pedagogical, stage and local) have been identified. The most sought after in modern Olympic martial arts is pattern technology with elements of modification using a variety of tools – 55.00% of experts (n=40) supported its use. Other technologies are applied by a narrower circle of specialists: variant, with various tools – 30.00% of specialists; template with modification elements with limited range of tools – 7.50%; template, without modification, with limited range of tools – 2.50%; template-variant, with various tools – 5.00%. Conclusions. The universal technology of athletes’ tactical training, relevant for modern martial arts, is a template with modifying elements, which provides the use of various tools. Other technologies (variable, template without modification, template and variable) are in demand for a narrow circle of specialists. Keywords: combat sports, tactics, skills, stages, methods.

Mixed martial arts - a sport, which is a combination of many techniques, schools and direction of combat sports. Nowadays, mixed martial arts are the most popular and spectacular sport of all combat sports. Analysis of competitions performances is an important aspect of training athletes. The quantitative characteristics of competitive activity make it possible to model the training process at different stages of fighters. Aim of the research – to analyze the quantitative characteristics of competitive activity of high ranked fighters. All matches of Mixed martial arts Russian Cup in 2018 were analyzed: 84 preliminary and 8 final fights (for 1 place) in all weight categories.  The following quantitative characteristics of the competitive activities of high ranked fighters were analyzed in the study: average fight time; average fight time in the standing and ground positions; distribution of fights by types of victory; activity, defense and reliability performing takedowns for each weight category. Also, a comparative analysis was carried out with the competitive activity characteristics of the top athletes from the Ultimate Fighting Championship rating for each weight group. These data can be used as model when planning the training process of both young and qualified athletes.

No other talent process has been the subject of such great debate and emotion as performance management (PM). For decades, different strategies have been tried to improve PM processes, yielding an endless cycle of reform to capture the next “flavor-of-the-day” PM trend. The past 5 years, however, have brought novel thinking that is different from past trends. Companies are reducing their formal processes, driving performance-based cultures, and embedding effective PM behavior into daily work rather than relying on annual reviews to drive these. Through case studies provided from leading organizations, this book illustrates the range of PM processes that companies are using today. These show a shift away from adopting someone else’s best practice; instead, companies are designing bespoke PM processes that fit their specific strategy, climate, and needs. Leading PM thought leaders offer their views about the state of PM today, what we have learned and where we need to focus future efforts, including provocative new research that shows what matters most in driving high performance. This book is a call to action for talent management professionals to go beyond traditional best practice and provide thought leadership in designing PM processes and systems that will enhance both individual and organizational performance.

Aim: boys of the second childhood period at the initial stage of martial arts to study the age characteristics of Mashkov’s diamond and the depth of the vertebral pole lordosis at the cervical and lumbar level as indicators of posture. Material and methods. 28 boys of the second childhood period (8-12 years) engaged in martial arts on the basis of JUSS No. 3 by V. G. Khromin of Tyumen were examined. The evaluation of Mashkov’s diamond was carried out according to the conventional method. The depth of the vertebral column lordosis at the cervical and lumbar level as an indicator of posture was assessed with the help of the device proposed by us (Russian Patent for useful model No. 30253). Results. The age-old size of Mashkov’s diamond sides increased as the boys grew up and did not indicate scoliotic spinal column disease. The “jumps” of its increase in the period of 11-12 years have been revealed. The age-related increase in the depth of lordosis at the cervical and lumbar level of the spinal column, more pronounced in the lumbar department, has been noted. Conclusion. According to Мashkov’s diamond, boys of the second childhood period have no abnormalities on the part of the spinal column. The depth of the vertebral pole lordosis at the lumbar level exceeds the depth of the cervical lordosis, which should be taken into account when dosing physical activity in physical education classes in the secondary school and during the training process in JUSH.

The Relationship

Introduction: the influence of the material branches of law on the content and development of procedural branches has long been substantiated in the legal literature. At the same time, civil law scholars, limited by the scope of the nomenclature of scientific specialties in legal sciences, do not have the opportunity to conduct dissertation research aimed at identifying the influence of procedural branches on the norms of substantive law. With regard to scientific research, the study of such an impact is currently permissible only within the specialty 12.00.15. Reforming the nomenclature of scientific specialties towards its enlargement creates the basis for the development of the scientific theory of intersectoral relations, developed by M.Iu. Chelyshev. An in-depth study of the intersectoral interaction of civil law and civil procedure will contribute not only to the development of scientific knowledge, but also will allow solving practical problems at a different methodological level. Purpose: to analyze the stages of the formation of scientific specialties in the context of the relationship between civil law and procedure, to identify the advantages and disadvantages of uniting and dividing civil law and procedure in scientific research, to analyze dissertations in different periods of development of the science of civil law and the science of civil procedure, to formulate ways to improve directions of research to bridge the gap between the science of civil law and procedure. Methods: empirical methods of description, interpretation; theoretical methods of formal and dialectical logic. The legal-dogmatic private scientific method was used. Results: identified the main views on the ratio of material and procedural branches in legal science; it is illustrated that the intersectoral approach is currently admissible only for dissertations in the specialty 12.00.15, which led to an almost complete absence of scientific research on this topic in civil science; substantiated the need to establish the bilateral nature of the relationship and interaction of material and procedural block. Conclusions: reforming the nomenclature of scientific specialties by right in the direction of their enlargement should have a positive effect on bridging the gap that has developed between works on civil law and civil law procedure in the last years of their separate existence. This is especially true of civil science, which developed its own scientific theories in isolation from the possibilities of their implementation within the framework of procedural law. The methodological basis for solving these problems has already been formed – this is an intersectoral method, the application of which is justified and demonstrated in the works of M.Iu. Chelyshev.
