Today it is important to develop a Specialized set of Scientific and Methodological support for long-term training of Veteran Judokas, which will ensure the formation of an effective Technical and Tactical Arsenal of wrestlers of the studied category (taking into account their individual-typological, psychophysical features) and promote their successful Competitive activities. The main Purpose of the study is to determine the effectiveness of the Experimental Program of Technical and Tactical training of Veteran Judokas in the System of their annual Training Cycle. During the Empirical Study, the following methods were used: abstraction, analysis and synthesis, induction and deduction, modeling, expert evaluation method, mathematical and statistical (correlation analysis, factor analysis, scaling), modern scientific tools and more. As a result of Research and Analytical work, members of the Research Group determined the effectiveness of the Experimental Program of Technical and Tactical training of Veteran Judokas in the System of their annual training Cycle. It is established that the gradual Formation of Technical and Tactical skills of Veteran Judokas (different age groups and weight categories) taking into account the peculiarities of the annual training Cycle provides an increase in their competitive activity, which indicates the high efficiency of the Experimental Program. Prospects for Further Research in the chosen direction of Scientific Intelligence include the development of a Pedagogical Model with technical means of teaching the Formation of Readiness of Veteran judokas (women) for competitive activities in the System of their long-term training.

According to the results of the analysis of the scientific and methodological, special and reference literature, the members of the research group established, that the issue of comparative analysis (analytical and statistical review) of the technical and tactical preparation of highly qualified judokas (men and women) – is dedicated to the insufficient number of scientific and methodological works, which requires further research and emphasizes the relevance and practical component of the chosen direction of scientific research. The main goal of the study is to conduct a comparative analysis of the technical and tactical arsenal of highly qualified judokas (men and women) of the finalists of the 2022 World Judo Championship (Tashkent, Uzbekistan). During the theoretical research, the following methods were used: axiomatic, idealization, historical and logical, descent from the concrete, formalization (mathematical and statistical), etc. As a result of a theoretical study by the members of the research group (according to the plan of the initiative scientific project "Championship Judo", 2022), a comparative analysis of the technical and tactical arsenal of highly qualified judokas (men and women) of the finalists of the 2022 World Judo Championship (Tashkent, Uzbekistan). In order to increase the effectiveness of the competitive activity of Ukrainian athletes (men and women) who specialize in judo at various stages of their long-term training, it is advisable to focus the attention of leading coaches on the development of appropriate training programs (pedagogical models) that provide: perfect mastery by judokas of the theoretical aspects of the current rules of judo; increasing the number and variety of attacking and defensive techniques; increasing the reliability coefficient of technical and tactical actions (combinations); development of tactile sensitivity and coordination; formation of high psychophysical readiness for long-term competitive activity (high training loads); the rational construction of a competitive fight taking into account the individual typological (psychophysical) features of the opponents; development of "explosive power", increasing the intensity of the training load; increasing the number of technical and tactical actions (combinations) per unit of time; development and improvement of special physical readiness, etc. Prospects for further research in the chosen field of scientific research include an analytical review of the technical and tactical preparedness of female athletes who specialize in sambo wrestling (champions and medalists of the 2022 World Championship).

The sorption of hydrogen isotopes by a composite nanostructured carbon material containing palladium clusters with an average size of 3–5 nm was studied in the temperature range of 8–290 K. The total amount of sorbed hydrogen strongly depends on the method of manufacturing the composite and is 2–4.5% of the sample mass. In the kinetics of hydrogen sorption and desorption by a composite, two processes with characteristic times differing by more than an order of magnitude are identified. The relatively fast process seems to be related to the filling of the cavities of the carbon matrix with hydrogen molecules, the longer one corresponded to the diffusion of hydrogen into the crystal lattice of palladium nanoclusters. Two temperature regions are found for the temperature dependences of the diffusion coefficients of hydrogen and deuterium in composite samples. Above 60 K, the diffusion activation energies in the sample containing palladium nanoclusters were more than twice the values obtained for the pure carbon matrix. Below 60 K, the diffusion coefficients of deuterium in the pure carbon matrix weakly depended on temperature. In the case of diffusion of hydrogen and deuterium into palladium nanoclusters, a change in the character of the temperature dependence was observed at a lower temperature (∼30 K). Below this temperature the activation energy decreased by approximately an order of magnitude.
