“…However, such an enhancement of power due to CM may differ between jumps and squats, depending on demands on the utilization of elastic energy during athlete performance (Zemková et al, 2017c ). While this potentiating effect is greater during jumps than squats in high jumpers and volleyball players, opposite is true for rock & roll competitors in acrobatics and dancing.…”

Neuromuscular training in young athletes improves performance and decreases the risk of injuries during sports activities. These effects are primarily ascribed to the enhancement of muscle strength and power but also balance, speed and agility. However, most studies have failed to demonstrate significant improvement in these abilities. This is probably due to the fact that traditional tests do not reflect training methods (e.g., plyometric training vs. isometric or isokinetic strength testing, dynamic balance training vs. static balance testing). The protocols utilized in laboratories only partially fulfill the current needs for testing under sport-specific conditions. Moreover, laboratory testing usually requires skilled staff and a well equipped and costly infrastructure. Nevertheless, experience demonstrates that high-technology and expensive testing is not the only way to proceed. A number of physical fitness field tests are available today. However, the low reliability and limited number of parameters retrieved from simple equipment used also limit their application in competitive sports. Thus, there is a need to develop and validate a functional assessment platform based on portable computerized systems. Variables obtained should be directly linked to specific features of particular sports and capture their complexity. This is essential for revealing weak and strong components of athlete performance and design of individually-tailored exercise programs. Therefore, identifying the drawbacks associated with the assessment of athlete performance under sport-specific conditions would provide a basis for the formation of an innovative approach to their long-term systematic testing. This study aims (i) to review the testing methods used for the evaluation of the effect of neuromuscular training on sport-specific performance in young athletes, (ii) to introduce stages within the Sport Longlife Diagnostic Model, and (iii) to propose future research in this topic. Analysis of the literature identified gaps in the current standard testing methods in terms of their low sensitivity in discriminating between athletes of varied ages and performance levels, insufficent tailoring to athlete performance level and individual needs, a lack of specificity to the requirements of particular sports and also in revealing the effect of training. In order to partly fill in these gaps, the Sport Longlife Diagnostic Model was proposed.

“…The ability to perform the following technical actions better than the previous ones leads to a significant reserve to improve the effectiveness of the game in general [35][36][37][38][39][40]. Other authors [41][42][43] emphasize the development of accuracy through strength exercises. Such approaches of the authors indicate the need to find new approaches in the training of elite volleyball players [44][45][46].…”

Background and Study Aim. Aim is to determine the influence of the components of special physical training on the effectiveness of certain elements of the game technique during the competitive activities of beach volleyball athletes. Material and methods. The study involved athletes (n = 20, age - 17-21 years, experience - 8-9 years), who are engaged in beach volleyball (Kherson, Ukraine). Experts (n = 5, work experience - over 20 years) from among the leading volleyball specialists were involved. Training sessions were conducted according to the author’s structure and content of special physical training (preparatory period of the annual cycle). The author's program was to increase the volume of athletic work by 10% (selective classes and integrated work) and 17% (complex classes). The classes used a developed special training device. The device is designed to practice practical game skills. The load at the first stage was 70-80% of the maximum. The load in the second stage was 80-90% of the maximum. Results. Significant (p <0.05) development of explosive power, speed and agility was revealed. There is a significant (p <0,05) increase: in the number of jump serve and spike; improving the quality/number of serve and attack; improving the quality of passing and the number of blocks. Conclusions. The proposed structure and content of special physical training and exercises on a special simulator have significantly increased the level of development of physical qualities. The athlete training program helped to improve the effectiveness of certain technical actions during competitive activities.

“…The authors propose creating a database that can be used to identify trends for training stages. Prospects for creating models of behavior of athletes and areas of technical training are presented in the studies of Gea et al [3] and Zemkova et al [4]. Similar opinions about the need to identify promising areas of research can be traced in the works of other authors [5][6][7]: model of orientation towards success; forms of partnership between two athletes that will help in achieving success; approaches to creating a familiar training environment for athletes.…”

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.
