IDO MOVEMENT FOR CULTURE

Background. Power and speed are decisive abilities for success in taekwondo. Elite competitors in taekwondo perform better in all power variables than the sub-elite.
Problem and Aim. The ability to exert large forces in a short amount of time is essential to achieving a high level of athletic performance in taekwondo. The aim of the study is to determine whether and to what extent power variables influence the kick speed in young taekwondo competitors.
Material and Methods. The sample formed of 28 participants aged 14 to 17 years (13 cadets and 15 juniors). Data of power variables were collected using tests in which maximal vertical jumps were performed. The optical system was used for the measurement. The speed of kicks was diagnosed using an electronic sparring system.
Results. A significant correlation between power and speed variables was proven only in the group of juniors who had higher values in all power variables. The age groups did not differ significantly in the speed of taekwondo kick execution. With the increase in the power value, the correlation coefficients between the variables also increase. The reactive power index was recorded as the variable that was most associated with the kick speed. Body dimensions did not affect the speed of taekwondo kicks.
Conclusion. The results obtained confirmed the current theoretical views on the positive influence of power on the movement speed in taekwondo. The nervous system plays a more important role in the motor control than the maximum muscle force.
