How often do you see Mixed Martial Artists chamber their knee before kicks (especially before a roundhouse)? From Wikipedia: "The taekwondo roundhouse kick, is performed by first drawing the knee straight up in a "chamber" position. This chamber, identical to the chamber of many taekwondo kicks (front kick, side kick, etc.) is utilized so that the opponent cannot guess which kick will be thrown. This differentiates it from Muay Thai and other roundhouse kicks, which tend to incorporate rotation before or during the rising of the knee. The knee is then rotated so that it is nearly parallel to the ground (counterclockwise for the right leg roundhouse) and the kicking hip is simultaneously rotated towards the opponent. The rotation of the hip, combined with the snapping of the leg forward, gives the kick its power. The striking surface is the instep or the ball of the foot. This is also called an "off the line" or "rear leg" roundhouse kick." While some might argue that chambering the knee before the kick comes at the expense of power, I feel that the speed of the kick and the fact that the kick remains "hidden" more than compensates for the "lack" of power.
