ABSTRACT
Introduction:
With the gradual improvement of the theoretical system of sports biomechanics and the high requirements of Taekwondo development, the scientific research of Taekwondo is no longer restricted to a monothematic perspective; sports biomechanics is a combination of the complex forms of movement and body changes in the sport, a discipline that combines the principles of mechanics and biology for research. This discipline, allied to the study of sport, contributes to the correct understanding, training, and mastery of movement techniques.
Objective:
Apply a technical analysis of the taekwondo kick through a sports biomechanics approach.
Methods:
Using a three-dimensional kinematic motion capture system, volunteers of 58kg, 68kg, 80kg, and three other weight classes, in a total of 30 athletes, participated in this research. The movements included technical kicks and the collection of motion trajectories when hitting the target.
Results:
There were significant differences in the angle, angular velocity, torque, action time, displacement, and velocity of the lower limb joints of the three weight classes (P<0.05).
Conclusion:
The higher the athlete’s weight, the lower the body agility; although the striking distance is relatively long, the impact on movement speed is relatively minor. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
