In the general result of this study, the effect of one- two straight in 3-segmentation of 3 types to which wheel and axle is applied shows average difference in type with respect to time, right hand speed, acceleration and angle of elbow, it does not show statistically significant difference. The central displacement, speed of left hand and angle of left/right shoulder joint shows significant difference as per existence/inexistence of pronation of forearm (p<.05). In the angular velocity of elbow joint, the type 1/3 show DM 4.84°/s (p<.05) in phase 1, type 1/2 show DM 12.95°/s in phase 2 and type 1/3 show 11.72°/s, which is significant difference(p<.001). As pronation movement shows faster angular velocity than non-pronation movement in the left/fight elbow angular velocity in each type, it can be considered as the cause that increases linear velocity of hand. Furthermore, the pronation movement of forearm of main joint shows time and velocity in type 2/3 which is faster than that of type 1 in phase 2. The displacement is also large in shoulder joint depending on existence/inexistence of pronation. Thus, it was concluded that type 1 is proper to fast punch in short distance, type 2 to fast and strong punch in medium distance and type 3 to counter punch in long distance. If utilizing and using the most proper distance and space in 3 types on the basis of conclusion of this study, the ideal and effective technique can be exercised.
