Study purpose. Determination of the peculiarities of the manifestation of strength in competitive exercises of highly qualified armwrestlers with different strength abilities.
Materials and methods. ...The study involved the 4 best armwrestlers in the world weighing from 80 to 100 kg (m = 87.50 ± 2.47 kg) in 2017–2020. Four power test exercises have been identified that ensure the performance of a competitive action in armwrestling: flexion of the fingers, stretch with a hammer, hook and bending the hand. Strength indicators in all test exercises were measured with an FL1K 0.5N, 1000N electric strain gauge dynamometer, Kern & Sohn GmbH (China), fixed on the armwrestling table using an author’s block device.
Results. The results of the correlation analysis of the relationships between the studied indicators confirm the presence of a difference in the direction and strength of the relationships between the strength and time characteristics of the efforts of athletes with different strength and speed-strength abilities. Thus, out of 36 correlation indicators, the data of armwrestlers 1 and 2 have 11 modules with very high connection strength (r = 0.926–0.999), of which 7 modules are with time and 4 modules are with force characteristics of efforts. Athletes 3 and 4 also have 3 modules with very strong connections (r = 0.916–0.948) and 8 modules with strong connections (r = 0.739–0.886), of which 7 modules are with strength indicators and 4 modules are related to time characteristics. But the other correlation indicators have very weak (r < 0.29) and weak (r = 0.3–0.5) levels of relationships.
Conclusions. Analysis of the time and force characteristics of the manifestation of force in the process of achieving boundary resistance allows us to clearly establish the genetically determined speed and strength abilities of the explosive, fast and slow force of armwrestlers.
Purpose: determination of the main components of power capabilities that ensure the success of the competitive exercise of armwrestlers weighing 80-100 kg. Material and Methods. The study involved 4 ...best armwrestlers in the world weighing from 80 to 100 kg (m = 87.50 ± 2.47 kg) in 2017–2020: athlete 1 is a multiple world champion weighing 90 kg (Ukraine), athlete 2 is a multiple champion world champion weighing 82 kg (Ukraine), athlete 3 - multiple world champion weighing 93 kg (Ukraine), athlete 4 - multiple winner of international competitions weighing 85 kg (USA). During the study, strength indicators were determined in 4 competitive exercises. Strength indices in all test exercises were measured in a static mode by an FB5k series electrical tenzodynamometer (Poland) with an accuracy class of up to 100 g, which was mounted on a special armwrestling table using a specially made block device. The created design was called the “ARM1 Device” (patent 43082). During the 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), gradient of the total strength of four exercises (t0,5F), strength index in the first 100 ms and 500 ms, speed-strength index in the first 500 ms (F500/t500), hour of reaching a force of 1 kg (t0,5F/(0,5×F); Pearson correlation analysis. Results. As a result of the study, the main data on the speed-strength indicators of armwrestlers were obtained and analyzed. In the process of testing, according to the indicators of time periods and given efforts of dynamic strength, the features of the manifestation of the explosive, fast and slow strength of arm wrestlers 80-100 kg were established. Conclusions. 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. This makes it possible to determine the natural ability to manifest dynamic strength, as well as to select and predict the performance of promising athletes, to specify the direction and content of the training process, and to clarify the program of participation in competitions.
