Background and Study Aim. Predicting the results of martial arts competitions is an important task that attracts the attention of both sports analysts and fans of these sports. The objective of this study is to perform an analytical examination of publications on martial arts prediction, with the aim of identifying the primary research directions in this field. Materials and Methods. the bibliometric analysis of PubMed database data was used to create a sample of studies at 18.05.2023. The keywords "prediction", "martial arts" were used for the search. A total of 151 publications were found. The first publication was dated 1983. VOSviewer 1.6.19 program was used: keyword analysis method and direct citation analysis with the construction of bibliometric maps, the visualization of cluster density, weights – citations. Results. 51 journals from 21 countries were identified. The unconditional leader among the countries is the United States (16 journals). Between 1983 and May 18, 2023, 741 scientific works were found. The analysis involved 67 authors whose link strength was more than 0. Eight clusters were identified. They were characterized by the presence of 271 links with total link strength of 276. The number of items in the clusters did not have a significant difference; this can be explained by the popularity of all directions in the research. The authors of the seventh and eighth clusters had the most publications. To visualize the network 63 items (keywords) were selected. They were grouped into 4 clusters. The network includes 951 links; the total link strength is 4027. The most popular studies are highlighted. These studies include the following keywords: "humans", "martial arts", "female", "male", "athletes", "young adult", "middle aged". Conclusions. The analysis of the bibliometric maps revealed the tendencies of scientific research and highlighted the priority areas. The relevance of the problem of prediction in martial arts is confirmed. An increase in the number of publications in PubMed database over the past decade has been observed. The main areas of research include martial arts, health, sports training, and humans. Most publications focus on utilizing artificial intelligence and machine learning techniques for predicting competition outcomes. Additionally, they explore the application of analytical tools to uncover patterns in data and identify critical factors that impact competition results. Modern technologies and the availability of big data open up new possibilities for predicting competitive success in martial arts.

PROGNOSTICATION OF SUCCESSFULNESS IN ARM-WRESTLING ON THE BASE OF MORPHOLOGICAL FUNCTIONAL INDICATORS’ ANALYSIS

Background and Study Aim. The importance of psychophysiological features in optimizing the functional state of athletes is beyond doubt. The aim of this study was a comparative analysis of the psychophysiological features of taekwondo athletes of different age groups. Material and Methods. The study involved 42 taekwondo athletes, skill level 2 Gup – 1 Dan. The participants were divided into groups of 14 people. Group 1 – (7.50±0.14) years, Group 2 – (10.07±0.22) years, Group 3 – (13.36±0.27) years. A special computer program for devices with the iOS operating system was used. The Apple iPad, 4th generation with a screen diagonal of 9.7 inches was used. The following tests were used: reaction choice (RC), reaction to a moving object (RMO) and size test (ST). The results of the groups were compared using the nonparametric Rosenbaum test (Q), and the Pearson correlation coefficient (r) was determined. Results. RMO test results in group 2 were significantly better than those in group 1 (Q=12, p<0.01). A similar correlation was determined for RC (Q=14, p<0.01) and ST (Q=15, p<0.01). When analyzing the frequency of incorrect reactions in RMO, it was found that athletes in the 1st group lagged behind more often (Q=6, p<0.05). A comparison of groups 2 and 3 confirmed that senior athletes had better results in RC (Q=11, p<0.01). For all tests used, the best results of group 3 compared with group 1 was determined: for RMO Q=16, (p<0.01), for RC Q=22, (p<0.01), for ST Q=20, (p<0.01). Senior athletes often had an anticipatory reaction in RMO, (Q=7, p<0.05). Significant correlations (p<0.05) were determined in group 1 between age and frequencies of anticipatory (r=-0.57) and lagging reactions (r=0.57), RMO and RC (r=0.63), RC and frequencies of anticipatory reactions (r=0.57) and lagging reactions (r=-0.57). In group 3, significant correlations were determined between age and RC (r=-0.59), RMO and RC (r=0.76), age and ST (r=-0.53), RMO and ST (r=0.65), RC and ST (r =0.79). Conclusions. A change in the speed of reaction to various stimuli of taekwondo athletes of different ages has been confirmed. An increase in age and training experience improves the reaction rate. This dependence is most pronounced when comparing junior and senior athletes. The determined correlations between all tests used also reflect the improvement in the psychophysiological state of the athletes with increasing age. The tests used are characterized by accessibility, specificity, informativeness and financial feasibility. The results obtained allow for recommending their use in monitoring the state of martial arts athletes.

Background and Study Aim. The increase in the popularity of sports dances recently has been confirmed. Dancing combines sports and aesthetic components. Dances are used for sports, recreational and rehabilitation purposes. The study aim is an analytical analysis of publications devoted to sports dances and the determination of priority scientific areas in this field. Material and Methods. The bibliometric database Web of Science Core Collection (WoS) is analyzed. For the primary analysis, 618 sources were selected which met the search criteria for 2018–2022. We used bibliometric methods for processing the information received in the context of sports dances for 173 sources. The VOSviewer 1.6.18 program was used: keyword analysis method and direct citation analysis with the construction of bibliometric maps, visualization of cluster density, weights – citations. Results. The constructed bibliometric maps made it possible to identify the leading thematic areas of research, current areas of research in this field. They can be divided into sports, recreational, medical and rehabilitation areas. The sports context is aimed at studying the performance of technical elements, the development of the physical qualities of athletes, the assessment of physical fitness, the dynamics of the morphofunctional state. Psychophysiological studies are aimed at analyzing balance and equilibrium. Publications of a recreational orientation study the health-improving use of dances, their impact on health. The medical and rehabilitation direction explores the features of sports injuries in dancing, injury prevention and the possibility of using dances in the complex rehabilitation. The use of the VOSviewer program, version 1.6.18, made it possible to conduct a comprehensive analysis of the problem, to determine the priority scientific directions in this area. Conclusions. The conducted bibliometric analysis of publications confirms the relevance of the problem of sports dances. A constant research interest in this problem has been determined. Research in this area has a pronounced sports and medical focus. Bibliometric analysis of publications allows identification the three following areas: sports, recreation and rehabilitation. Dancing is being explored as a sport, a form of physical activity, and a form of rehabilitation. A fairly high level of sports injuries has led to interest in the analysis of the prevalence and prevention of injuries. Its characteristic feature is the intersection of these directions. The study of athletes’ state confirmed the lack of works devoted to a comprehensive study of athletes, predicting success and skill growth. There are not enough works studying the physical state of sports dancers. There are practically no studies aimed at studying the psychophysiological state. These types of studies should be assessed as relevant.
