According to the Results of monitoring of Internet resources, analysis of Scientific-Methodical, Special and reference literature, members of the Research Group established, that the issue of implementation (determination of effectiveness) of Modern Scientific tools, as well as Technical means of Training that provide a System of long-term training of athletes specializing in Martial Arts – is devoted to an insufficient number of Scientific and Methodological works. This requires Further Scientific Research and emphasizes the relevance and Practical component of the chosen area of Research. The main Purpose of Scientific Research is to determine the effectiveness of modern Scientific tools ("VKS Katsumoto" and "Visual 3D") in the System of long-term training of wrestlers (on the example of athletes who specialize in Sambo wrestling). In the process of Research and Analytical work, the following Research methods were used: abstraction, Analysis and Synthesis, induction and deduction, modeling, mathematical and statistical, etc. As a Result of Empirical Research, the effectiveness of modern Scientific tools has been determined "VKS Katsumoto" and "Visual 3D" in the System of long-term training of athletes specializing in Sambo (Sports and Combat direction). Prospects for Further Scientific Research in the chosen direction of Research include a comparative analysis of the performance of Ukrainian sambo wrestlers at the 2021 World Cup using modern Scientific tools (Technical Teaching Aids).
