In Figures 46 through 48 the attacker has completed the punch before his body motion has stopped. Beginning in the left front stance (Fig. 46), he steps forward to begin a lunge punch, but his hand is fully extended in the punch before his body movement stops (Fig. 47). In the last photo (Fig. 48), the attacker has completed the step, but it has not been coordinated with the punch, and the combined power of body movement and hand movement has not been achieved.
Figures 49 and 50 demonstrate the correct method of utilizing hand and body power. The attacker begins in the left front stance (Fig. 49) and then steps forward with his right foot to execute a right lunge punch (Fig. 50). Note that his foot has advanced, but his hand has not begun the punch. This is necessary, since hand movement is much quicker than body movement. In Figure 51 we see the completion of the punch. Maximum force has been developed, since the hand and foot have reached their terminal position at the same time.
This coordination of body movement is possible in both forward and backward movements. The key to developing power in both directions is to make sure that the hand and foot stop at the same time.
Hip Movement and Centrifugal Force
A basic understanding of the physical forces that affect karate movements is necessary in order to achieve maximum power in techniques. Many karate practitioners fail to understand them and thus do not reach their full potential in regard to the amount of force that they generate. One such physical force is centrifugal force.
As demonstrated in previous sections, reaction force is generated in a kick, punch, or block by withdrawing the opposite arm or leg. This sharp movement usually causes some rotation movement in the hip. However, if a rotating movement is initiated by the hip as the punch is executed, then centrifugal force will be added to the reaction force, producing the strongest possible punch. An easy comparison is the swing of a batter as he attempts to hit the ball. Although coordination of the batter’s swing has been discussed above, it should also be noted that a batter who does not rotate his hips and body into the swing of the bat will have a very weak swing. Baseball fans can observe this easily, and recognize that the same principle applies to many other athletic movements, including karate punches, kicks, and blocks.
