Related scholars have proposed a very classic graph structure algorithm [14]. e author uses a collection of multiple parts to express the human body, and there are certain spatial constraints between these parts.…”

Serving is one of the most crucial techniques in volleyball. Serving is a method that does not require team interaction and is difficult for the opponent to immediately interfere with. The feature migration module with a fixed offset is suggested in this work. This module can be thought of as a cross-channel dilated convolution approximation of dilated convolution. The reason cross-channel dilated convolution is not worse than standard dilated convolution with few parameters is discussed in this article. An improved random forest model is put forth to address the issue of the human pose estimation system’s high memory consumption when utilizing random forest as the classifier. This model presents the Poisson process and incorporates it with the depth data to create a filter before using Bootstrap sampling. In order to optimize and reconstruct the training dataset, a portion of the feature sample points that do not contribute positively to subsequent classification is removed from the original training dataset. This allows the training dataset to better account for the repeated sampling of the random forest during the sampling process. Resampling has some drawbacks, but they are not very representative. The effectiveness of the optimization model, which significantly lowers the system’s time and space complexity and increases the system’s applicability, is demonstrated by experiments.

Background and Study Aim. The physical fitness of students is characterized by the level of their abilities development to perform movements of varying complexity. One of the important components in the system of movements is coordination skills. The aim of the study is to identify the level of special and general coordination of students majoring in "Choreography" and provide recommendations for the development of coordination skills in the process of studying modern-jazz dance. Material and Methods. The study involved students of the first and second year of study (n = 10, at the beginning of the study (1 year) age - 17.4 ± 0.7 years) majoring in "Choreography". Tests were used to determine the level of development of general and special coordination skills. The level of coordination readiness at the beginning of training and after three semesters of training was determined. The study was conducted over three semesters (September 2019 - December 2020). Curricula for students’ training do not include the discipline "Physical Education". The development of physical qualities is the task of special subjects in the course of professional training: 16 hours per week. The workload of students in modern-jazz dance was 2 hours a week. Forms of study for a certain period - full-time (70%), online learning (10%), mixed (20%). In September 2019 and in December 2020, the same students passed selected tests. Results. The following significant changes in increasing the coordination level of the abilities were determined: to control temporal and spatial factors of movements; coordination of movements in combination; vestibular stability; musical-rhythmic coordination (p <0.01). The proposed technique assumes that at the first stage of studying modern jazz dance two, three, four centers are coordinated in simultaneous parallel movement. Conclusions. The need to improve the curriculum of modern jazz dance, the introduction of additional courses to the educational program in the major "Choreography". The technical and lexical base of modern jazz dance in combination with special physical training provides opportunities for the coordination skills development in choreographers.

“…The authors believe that serve (standing serve, jump serve, float jump serve) and spike have different performance profiles based on technique, player role, and age. Other studies consider: tactics of team actions [10]; attack tactics [11,12]; competitive activity [13,14]. In general, the WoS database presents a fairly wide range of research areas in beach volleyball.…”

Background and Study Aim. The inclusion of beach volleyball in the program of the Olympic Games gave some impetus to the development of scientific research on various problems of training athletes. Most of the research results are presented in journals included in the Web of Science Core Collection. However, the publication of research results in journals from national databases remains outside the scope of this database. The aim of this study is to systematically review the scientific literature on various beach volleyball issues in Russian-language scientific resources. Material and Methods. The sources of information were the authoritative database Web of Science Core Collection, Russian Science Citation Index, Scientific Electronic Library eLIBRARY.RU (Russia), National Repositary of Academic Texts (Ukraine). Data extraction from these databases was carried out using the keywords “volleyball” / “beach”. A total of 1,875 documents were found for the keyword “volleyball”. Of these, the keyword “beach” - 273 documents. Further analysis was carried out on 273 documents. The search query results were recorded in the form of tables and a special text file, which were processed in the VOSviewer 1.6.17 program. Results. The most significant and more popular subject categories, journals, authors, articles, keywords have been identified. The relationship between keywords and individual groups of publications has been established. A method for extracting data from the Scientific Electronic Library eLIBRARY.RU in a semiautomatic mode is presented. The trends in the development of beach volleyball in various aspects of the training of elite athletes and the sports reserve, the health-improving function of beach volleyball for youth are shown. Conclusions. Differences in the content of research between Russian-language and English-language resources are a good complement to each other. This fact may contribute to solving the problems of beach volleyball and international cooperation of researchers.
