초록

This research is for providing taekwondo masters and learners with statistical basic data by analyzing mechanically the movement of arae makki, which is very basic defensive skill.
To meet the purpose of this research, with 6 taekwondo masters, I analyzed the time required, the shift of physical center, speed, the range and speed of left fist, the angle and speed of the joint of left arm, angle of body twisting, and the repulsive force of floor. Through these, I could conclude like following.
The first, the average required time for arae makki was 0.68±0.11 s, and it was shorter than for Preliminary motion.
The second, the shift of physical center was not big in horizontal and vertical direction, however was big in back and forth direction. The speed of the shift was the fastest when the fist reached the highest.
The third, the range of fist moved from the right to the left, from up to down, and from inside to outside of body. The highest speed was 6.80 m/s.
The fourth, the change of the angle of arm was the biggest in elbow joint. bending was shown in preparing moves, and extension was shown in defending moves. The angle speed was the highest when checking the offense.
The fifth, the angle of body twisting was the biggest when the left fist was in the highest. At the moment of checking the offense, the twisted body recovered and the checking moves were completed. The repulsive force was 0.857±0.154 %BW.
