영문 초록

The purpose of this study is to analyze the characteristics of the spin kick moves in Taekwondo and provide necessary information to the university athletes in correcting their moves. It is also a goal of this study to quantify the forms of the kicks in training to maximize the efficiency. Four national varsity players of Taekwondo and four beginners with no award histories from K Univ. were given 6 weeks of training and motor mechanic analysis have been performed with the spin kicks. The conclusions of this study are as follows. 1. The total elapsed time of performing a spin kick move in each group differed significantly. The beginner group's elapsed time for a spin kick was an average of 0.415±0.158, while the national varsity group's spin kick took only 0.283±0.044. Therefore, the national varsity group turned out to show much more speed in spin kicks. Also, the procedures within individual moves of the varsity group appeared to shorten the entire elapsed time of a move compared to those of the beginner group. 2. In performing Step-and-Spin kicks, the two groups showed significant differences in the angles of joints such as the coxa, knee, and ankle. In case of the beginners, they failed to reduce the angle of the coxa joints, and the knee joint were not fully stretched out in the associated movement of Step-and-Spin kicks. Also at the impact, the dorsification of the ankle joint denied that accurate hits on the desired positions. But, as the training went on, the beginners showed improvements in narrowing down the angles. 3. The angular velocity of the coxa joints in both groups while performing a Step-and-Spin kick move, the angular velocities of each joint turned out to be rather higher. Such an outcome with the beginner group might be due to the lack of practices and thereby failure in controlling effective distances while associating each phase of the Step-and-Spin kick. 4. The surface recoil of the beginner group appeared to increase in its value as the training progressed in comparison with the national varsity group. Such a result was found to allow bigger motions when stamping, adding to the force directed upward from the ground. It can contribute to make faster and wider expansion angle movement. 5. In this study, while the Step phase in a Step-and-Spin kick is a precedent but a very important movement before the spin kick is performed, the beginners were found to fail in utilizing this phase efficiently due to lack of techniques.
