Abstract

Positive tendencies of arm-wrestling's expansion condition demand in its scientific study and determination of sportsmen's success factors. Such factors include strength of sportsman's forearm muscles' strength. The purpose of the research is comparative analysis of forearm movements' power characteristics of different qualification sportsmen and students, who do not practice arm-wrestling. Material and methods: in experiment 33 students of physical culture academy participated. The students were divided in two groups: experimental group-armwrestlers, (n=16, age 21.94±1.18 years), the second (control) group) (n=17, age 19.94±0.31 years)-students, who do not practice armwrestling. Depending on level of sportsmanship experimental group was divided into two subgroups: experienced sportsmen (n=5) and beginners (n=11). We used set of tests. In the tests we registered strength of flexing, extension, moving aside, forearm's pronation and supination by value of maximal weight in these movements. Results: higher strength of sportsmen, in comparison with control group, by all tested parameters has been confirmed (p<0,05). Especially greater sportsmen's strength is expressed with flexing of forearm. It reflects better physical fitness and illustrates specialized training in this kind of sports. Indices of strength's relation to mass improve visibility and permit to standardize the data for analysis and prognosis. Value of experienced sportsmen's flexing indices was more than 100%. It proves again importance of this movement for success in armwrestling. Analysis of correlation matrixes confirmed greater stability of sportsmen's condition. Reduction of functional tension happens at the account of 1.2-2.0 times increase of specific gravity of significant and confident correlations, as well as 2.48 times increase of synchronization indicators and 2 times increase of mean correlation coefficient. Conclusions: level of strength in flexing, extension, rotation and moving forearm aside is rather important for success in armwrestling. Usage of indices of strength-body mass relation is a promising way of selection and prognostication in armwrestling.

“…Our results supplement past data specific to the importance of development of motor abilities in adolescents (Khudolii, & Titarenko, 2010;Solianik, 2013); to obtaining new information with the help of simulation method (Khudolii, & Ivashchenko, 2014;Ivashchenko et al, 2016), and to guide theory of optimal teaching (Podrigalo et al, 2015a(Podrigalo et al, , 2015bBliznevsky et al, 2016;Iermakov et al, 2016aIermakov et al, , 2016b. Our results also supplemented past research findings concenring methodologic approaches to summarizing control of functional and motor fitness of adolescents (Ivashchenko et al, 2015a(Ivashchenko et al, , 2015b(Ivashchenko et al, , 2015cKhudolii et al, 2015a;.…”

“…These parameters characterize close associations with skill level, weight category and the level of athletes' special work capacity in the process of annual preparation cycle. Obtained data closely correlate with the results of studies of other authors (Mishchenko et al, 1999;Lisenko, 2003) as well as those of our earlier studies Podrigalo, Iermakov, Galashko, Galashko, & Dzhym, 2015;Podrigalo, Iermakov, Nosko, Galashko, & Galashko, 2015) with respect to the efficiency of current, operative and stage complex investigations of FF of highly skilled athletes in the dynamics of educational and training process.…”

“…The received results permitted to build mathematical models as well as to determine strength, orientation and form of the tested indicators. Podrigalo, Iermakov, Nosko, Galashko, and Galashko (2015) applied method of correlation structures for assessment of arm-wrestlers' condition. They proved that elite sportsmen's condition was more stable.…”
