Why do archers use recurve bow instead of traditional bows?

First of all, you should know the difference between backward flexion and straight pull (forward flexion)

The so-called backward flexion means that the arch tip has a forward bending shape, which is called backward flexion because it is opposite to the opening direction.

This curved shape makes the deformation of the tip of the bow more intense under the same deformation of the bow (the same as that of the straight rabbi).

Therefore, the rebound speed at the moment of deployment is much higher than that of the forward curve, the energy conversion efficiency of the bow is higher, and the initial velocity of the arrow is higher.

So recurve bow, with the same pulling force, can shoot faster than a straight bow.

With the same strength, who wouldn't choose a weapon that can shoot farther and more powerfully?
