Документ Analysis and evaluation of the features of the manifestation of dynamic power in leaders of the world armwrestling(National Pedagogical Dragomanov University, 2023) Bezkorovainyi, D.; Kamayev, O.; Mulyk, K.; Litovtsev, Y.; Zvyagintseva, I.; Plotnytskyi, L.; Glyadya, S.; Kravchuk, Y.The article reveals the definition of the features of the manifestation of the dynamic strength of the world's leading armwrestlers. The study involved 3 of the world's best armwrestlers weighing from 62 to 74 kg: athlete 1 – multiple world champion (m = 62 kg); athlete 2 – multiple US champion, winner of international competitions (m = 62 kg); athlete 3 – champion of Ukraine, winner of international competitions (m = 74 kg). Four power test exercises have been identified that ensure the performance of a competitive action in arm wrestling: flexion of the fingers, stretch with a hammer, hook and bending the hand. These exercises were performed with the left and right hands. Strength indices in all test exercises were measured with an FB5k series electrical tenzodynamometer (Poland) with an accuracy class of up to 100 g, fixed on a specialized armwrestling table using a specially made block device – “ARM1 Device” (patent #43082). In the course of statistical analysis, the following parameters were calculated: maximum and relative strength, total strength index in four strength exercises (F), time to reach maximum strength (t), speed-strength index (F / t), average strength index of four exercises (F / 4), the gradient of the total strength of the four exercises (t0.5F), the strength index in the first 100 ms and 500 ms, the speed-strength index in the first 500 ms (F500 / t500), the time to reach a force of 1 kg (t0.5F / (0.5×F)); Pearson correlation analysis. The study made it possible to establish indicators of the speed-strength index, strength gradient, the ability to manifest dynamic strength in the first 500 ms, clearly characterizing the speed-strength capabilities of armwrestlers and allowing to determine the features and nature of the manifestation of their dynamic strength. These indicators make it possible to determine the natural ability to manifest one or another type of dynamic force; clarify the direction and content of the training process; to conduct an effective selection of armwrestlers at different stages of a long-term training process; predict the expected sports result; determine the tactics of competitive activity of each athlete.Документ Methodological techniques for injury prevention during classes and competitions in armwrestling(National Pedagogical Dragomanov University, 2022) Bezkorovainyi, D.; Kamayev, O.; Zvyagintseva, I.; Glyadya, S.; Kravchuk, Y.; Kulakov, D.The article identifies the causes of injuries and developed methodical techniques for their prevention in arm wrestling. During the study, the protocols of 92 (n = 92) arm wrestling competitions of various levels, from club to international, were analyzed, and 156 (n = 156) competitive movements of athletes were analyzed when performing arm wrestling techniques. In the course of the study, the protocols of 92 (n = 92) different level armwrestling competitions, from the club to the international competition were analyzed, 156 (n = 156) competitive movements were analyzed for athletes when armwrestling performing techniques. The data obtained indicate that, along with the increasing number of competitions, the number of injuries gradually and significantly decreases. So, at the first stage, during 24 competitions, athletes received 50 injuries, which on average annually amounted to 6.250±0.701 cases; at the second stage, during 28 competitions, 15 injuries were received (1.875±0.441 cases annually); at the third stage, out of 40 competitions, there were only 4 injuries (0.500±0.267 cases annually). A clear and reliable dynamics in the reduction of injuries (P < 0.01–0.001) indicates that the development and spread of armwrestling has a positive impact on the professional development of coaches, referees and athletes. Significant dynamics of injury reduction indicates that preventive measures to prevent the causes of injury have a positive impact on the training of coaches, referees and athletes. The annual seminars with the involvement of qualified athletes made it possible to significantly improve the technique of performing competitive exercises, improve the means of preventing injuries, and increase the qualification level of judges. In addition, in recent years, the material and technical base for training athletes has been improved, the Rules for holding competitions have been adjusted, as well as the methodology for strength training of armwrestlers of various qualifications.
