Investigation of the relationship between the levels of manifestation of complex sensorimotor reactions of taekwondo athletes

Abstract

Purpose: to establish and analyze the relationship between the levels of manifestation of complex sensorimotor reactions of taekwondo players. Materials and methods. To achieve the purpose of the study, the following methods were used: analysis of scientific and methodological information and Internet sources; method of psychophysiological measurements; methods of mathematical statistics. Results: It is established, that the reaction time of a choice at highly skilled taekwondoists of the senior age is lower (better), than at taekwondoists-juniors from group 2 on 9,86% (p<0,05). Highly skilled taekwondoists have the smallest range of variation, which indicates more stable or consistent results. A higher median level and a larger range of values were observed in the group of junior taekwondoists, which indicates a greater variability of data in this group. The analysis of the average time of reaction of a choice at each stage separately showed that at highly skilled taekwondoists of the senior age this index increases on average on 88,12 ms, at taekwondoists-juniors - on 78,04 ms. The moderate inverse correlation by the criterion of Pearson between age and reaction time in group 2 (r=-0,52; p<0,05) is revealed, in group 1 such connection is not observed (r=0,07; p>0,05). The statistically significant positive relation according to Spearman's criterion between the time of choice reaction and the time of reaction to a moving object in both groups of sportsmen was established (for group 1: r=0,92; p<0,05. For group 2: r=0,50; p<0,05). It is established that the offered tests are an adequate and informative tool and can be used for monitoring of a functional condition of sportsmen in martial arts, in particular taekwon-do. Conclusions. The results of the comparative analysis of the manifestation of the choice reaction showed that highly skilled taekwondoists of the older age have it developed better than taekwondoists-juniors (p<0,05). Also the indicators of taekwondo juniors have a greater variability. The results of the analysis of interconnections between complex sensorimotor reactions confirmed that highly skilled sportsmen of older age have better developed abilities to quick and exact reaction than taekwondo juniors.
