PASSING MECHANICS > REVERSE-C

REVERSE-C

Reverse C refers to an excessive amount of extension occurring late in the turn and early in the acceleration phase of the throwing motion.  This is common to see in younger baseball pitchers.  The pelvis rotates forward (anterior) and is accompanied by hyperextension of the low back, with the chest drifting forward in front of the hips.

Why does it matter?

Reverse C may be an issue for some QBs because it corresponds to a more linear throwing motion that can place increased stress on both the low back and the throwing shoulder.  Efficient rotation at the pelvis and torso is important for transferring power from the hips to the ball. 

When pelvic and torso rotation is limited or not properly timed a quarterback may resort to more flexion-extension patterns to help generate force.  Over time, repetitive stresses created by an excessive flexion-extension pattern may lead to injury. 

Causes

The Reverse C characteristic is most commonly seen in quarterbacks who have difficulty controlling rotational movement of the pelvis.  Reverse C may be exaggerated by a lack of stability through the deep core stabilizer muscles.
