NERYO-CHAGI KINEMATIC CHARACTERISTICS EVALUATION IN IMPACT SINGLE COMBATS BY EXAMPLE OF WTF TAEKWONDO VIA FEEDBACK TECHNOLOGIES
This article is dedicated to topical issues related to feedback information technologies. As of now, there is not enough research on the topic of studying the kinematic characteristics of athletes in full-contact martial arts using tracking feedback systems. Research methodology: To test the hypothesis concerning the practicability of modern information technologies application, there was held an experiment with WTF taekwondo martial arts athletes. The researchers examined 4 athletes: 2 highly qualified athletes (elite) and 2 sub-elite athletes. The GPS/LPS RealTrack System by Wimu Pro Spain, was chosen to record the motion parameters. Neryo-Chagi was randomly chosen to assess the kinematic characteristics (exploratory study). Neryo-Chagi was considered as an integral motor action, which consists of two types of movement: 1) swing and 2) shock movement (strike). Research results: At the moment of Neryo-Chagi strike, there is a linear increase in the angular velocity (degrees/sec) from low to maximum. When performing a swing and a shock movement (strike), the angular velocity (deg / s) is different. The maximum angular speed during the swing is observed when strikes the way they are in a fight are compared to the maximum, medium and slow intensity. Swing time (s) with elite athletes is higher compared to sub-elite ones, while the time to perform a strike movement does not differ. Elite athletes have higher maximum angular velocity during the swing and strike movement. Evaluation of the main motor actions of athletes, classified by kinematic characteristics, allows a new assessment of their effectiveness. Article visualizations
APPLICATION OF MODERN INFORMATION TECHNOLOGIES OF FEEDBACK IN IMPACT MARTIAL ARTS ON THE EXAMPLE OF TAEKWONDO WTF
The article deals with topical issues related to the use of feedback information technologies. Since there are not so many studies on this topic, the review includes information on the example of other sports where research is already being carried out, as well as preliminary own research obtained on the example of athletes of percussion martial arts, taekwondo WTF. The study examines the main parameters of the kinematics of the movement of athletes, the study of which allows us to evaluate their effectiveness, and the magnitude of the impact, primarily when assessing the external side of the load. Feedback information technologies for continuous monitoring of motor activity are currently informative, reliable tools in the work of coaches, the information from which helps to plan the training process and carry out the continuous process of training an athlete both in different periods of the annual cycle and during the recovery period. Article visualizations
