Abstract
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.
