Relationship between the level of manifestation of sensorimotor reactions with indicators of physical fitness in young taekwondo practitioners

Purpose: to determine the relationship between the level of sensorimotor reactions and indicators of physical fitness in young taekwondo fighters. Material and methods. The following methods were used in the study: analysis of scientific and methodological information, Internet sources and generalization of best practices, psychophysiological research methods, methods of mathematical statistics. The study involved 16 young taekwondo fighters, aged 8-9 years. The pedagogical research was conducted in three stages. The first stage was devoted to the assessment of sensorimotor reactions, the second to the assessment of physical fitness of young taekwondo fighters, and the third stage was a correlation analysis between the indicators of sensorimotor reactions and indicators of physical fitness. Results: Based on the analysis of scientific and methodological information, Internet sources and generalization of best practices, it was found that one of the many tasks that coaches solve in the training process of young taekwondo fighters is to identify opportunities and inclinations to achieve high sports results in the future. The results of the study indicate the homogeneity of simple and complex reactions (from 5,20 % to 10,79 %), in addition to the index of complex response to a moving object, which has a high coefficient of variation (38,6 %). Indicators in tests that reflect specific perceptions also have a high coefficient of variation (from 16,5 % to 38,7 %). This can be explained by the fact that this type of reaction is of great importance in martial arts and the best results in these tests may indicate certain abilities of some athletes. Analysis of the results of physical fitness showed that in almost all tests there is a large variability of values (from 13,89 % to 96,02 %). The lowest value of the coefficient of variation was noted in the test «Shuttle running 3×6 meters» (V=7,77 %). Conclusions. Correlation analysis of the relationship between the level of manifestation of sensorimotor reactions with indicators of physical fitness showed that the values obtained by performing the test «Simple visual-motor reaction» have statistically significant relationships with the test «Shuttle running 3×6 meters» (r=0,51), and the values (test «Simple motility») statistically significantly interact with the values shown by young athletes in the test «Complex relay 15 meters» (r=-0,51). Other tests showed a weak level of correlation (r<0,5). The study of the relationship between the level of manifestation of sensorimotor reactions and physical fitness allowed to determine the level of interaction of the mechanisms of movement control of young taekwondo fighters and to form directions for improving the quality of the training process.
