The purpose of this study is to analysis and present descriptions of Wrist hitting motion of Gumdo. This study was carried out three dimentional kinematic analysis on wrist hitting motion of the two skilled and unskilled for instructing to novice. 1. There was no difference in AP or RFT during hitting wrist between the skilled and the unskilled, but the difference in the angle of the left wrist during impact between the skilled and the unskilled was significant(skilled; 152.64±1.32 and unskilled; 131.46±6.82). Therefore, it shows not only that the intensity and speed of hitting is better in the skilled than those in the unskilled but also the skilled reached at maximum angle of the left wrist while the unskilled didn`t. 2. Significant difference was not found in the algle of the left elbow at the event of AP, RFT and IP between the skilled and the unskilled(skilled; AP; 146.76±3.74, RFT; 114.66±2.31, IP; 163.11±5.62 and unskilled; AP; 137.97±0.70, RFT; 113.73±6.74, IP; 148.78±1.22). 3. There was difference in the angle of the left shoulder joint with the right foot taking off between the skilled and the unskilled(skilled; 123.67 ˚ and unskilled; 100.89 ˚). It shows that the skilled`s hitting was more efficient than that of the unskilled. 4. Significant difference was not found in the torque of the left wrist joint at the event of AP and RFT between the skilled and the unskilled. However, the torque of the left wrist joint was different significantly between the skilled and the unskilled(skilled; 31.06radian/sec and unskilled; 13.86 radian/sec). 5. In the IP, Despite of using the wrist joint, the unskilled was didn`t therefore, the unskilled was unefficient 6. There was difference in the torque of the left shoulder joint at the position of RFT between the skilled and the unskilled(skilled; -10,1±0.75 and unskilled;-6.57±6.29).
