學球的過程中，鮮少看到直臂正拍，我的球友徐x儒是我見到的第一位。由於他非muscle型選手，所以見不到力量的爆發，只覺得打球穩健。這是一個極強大的槓桿作用，維基百科對此解釋這種技術，如下:
Here is what Wikipedia has to say about the power of this technique:
| The stiff-arm fend is particularly effective because its force is applied down the length of a straight arm, directly into the shoulder. This puts the arm bones exclusively under compressive axial stress, the stress to which bone is strongest, and; ensures that minimal torque is applied to the shoulder joint. As such, the force that can be applied by a stiff-arm fend can easily repel or topple an oncoming defender. The same techniques are practised by martial artists when striking or punching; by ensuring that the direction of the force is directly down a locked, straight arm, martial artists can punch through bricks and tiles without damaging their arms. |
