Objective of the study was to conduct a comparative analysis of the kinematic characteristics of various strikes performed by WTF taekwondo athletes.
Methods and structure of the study. To achieve this goal, 12 highly qualified athletes were examined under the conditions of the training process: Candidate Master of Sports and Master of Sports. The athletes’ age is 21.0±1.7 years, height – 167.7±9.0, weight – 61.0±8.2 kg. The Wimu Pro system, Spain, was chosen as the system for recording motion parameters. To standardize the speed of strikes for athletes, a protocol with a task was developed. Each athlete had to perform blows: nerio chagi, ap chagi, dolio chagi, yop chagi with different intensity, determined by sensations - slow, medium, fast. The significance of differences between statistical data was determined using one-way analysis of variance in the Statistica program.
Results and conclusions. The results of the study made it possible to determine the kinematic characteristics for the main blows in WTF taekwondo: yop chagi and lobe chagi, as well as for ap chagi and nerio chagi. Each blow consists of a swing and a striking movement. The duration of the impact and the maximum angular velocity during the impact are indicators of the external load that must be taken into account when planning the training process in WTF taekwondo.

Keywords: speed, swing, kick, striking movement, athletes, taekwondo.
