Research of indicators of competitive activity of karateka

Purpose. to conduct a comparative analysis of the indicators of competitive activity of karateka of different ages. Material and methods. The following methods were used in the research: analysis of scientific and methodological information, Internet sources and generalization of best practices; video computer analysis; methods of mathematical statistics. Results: the research revealed that biomechanical indicators have an impact on the course of a fight. Taking these indicators into account allows you to build a fight to achieve victory. The research obtained the time characteristics of karateka's technical and tactical actions. They demonstrate that adult, highly qualified karateka perform technical actions faster than junior karateka due to a high level of technical training, speed and power abilities and the level of psychological preparedness. The percentage value of the difference in time characteristics was also determined, which is equal to 13,6 %±9. However, junior karate fighters perform the Gyaku dzuki kick 2,9 % faster than adult, highly qualified athletes due to the high level of physical fitness and technical level of this technique and the frequency of its application. The research observed differences in the technical arsenal of martial artists. Adult, highly qualified athletes perform a much smaller number of types of technical techniques, but more attempts to perform actions from the individual arsenal than junior karateka. Thus, the technical techniques of highly qualified athletes are more effective. The research obtained numerical indicators of the accuracy of karateka's technical actions, which are higher in adult, highly qualified karateka.43,7 % of the technical actions of adult qualified athletes fall into the scoring zone, and 24,3 % of technical actions of junior karateka. The experience and high level of training of martial artists allows adult, highly qualified karateka to hit the scoring zone more often and to carry out technical and tactical actions faster in constantly changing situations. Checking the obtained results for normality of distribution showed that there is a difference in the duration of technical actions of junior karateka and adult, highly qualified karateka and it is reliable (p<0,05). Conclusions. The higher level of technical and tactical, psychological preparedness, the greater competitive experience allow adult, highly qualified karateka to perform technical actions faster and more precisely. Highly qualified adult athletes perform techniques 13,6% faster than junior karateka. Adult highly qualified karateka hit the scoring zone when performing 43,7 % of technical actions, and junior karateka – 24,3 %. Checking the indicators of the duration of technical actions showed that highly qualified karateka perform technical actions statistically faster (p<0,05) than junior karateka. The application of the Mann-Whitney criterion showed that there is a difference between the duration of technical actions performed by adult highly qualified karateka and junior karateka, which can be considered statistically significant.
