상지 움직임이 태권도 발차기 총 수행시간에 미치는 영향

Abstract

In this study, 18 Taekwondo players are required to perform kicks such as Dollyeo-chagi, Balbutyeo-chagi, Dwi-chagi, Dwi Huryeo-chagi, Dolgae-chagi in the upper limb fixed state and the upper limb free state. To determine how the mean difference of total performance time of kicking is different, independent t verification was conducted and analyzed. As a result, the following conclusions were drawn. First, the upper limbs fixation was shown to increase the speed of kicking by limiting the movement of the shoulder joint and flexion of the elbow joint, thereby increasing the total performance time of kicking. Second, Dollyeo-chagi, Balbutyeo-chagi, Dwi-chagi and Dwi Huryeo-chagi had all statistically significant differences. However, in this study, the characteristic kick was Dolgae-chagi, which showed that the upper limb movement had a significant impact on the total performance time compared to other kicks. To sum up these conclusions, according to the upper limb movement, the mean difference in the total performance time of Taekwondo kicks is shown, which is consistent with prior research in other sports. Besides, the characteristic of kicking in the upper limb free state contributed to the flexion of the hip joint can be wider, and the kick of the straight line movement was carried out quickly, it is believed that the sequence of muscles required for kicking can be activated sequentially. Therefore, in Taekwondo training, which is a high proportion of lower limbs training, if we conduct both the upper and lower limbs training to increase coordination, it is judged that the total performance time of kicks will be reduced, and it will contribute to the improvement of the competition skill.
