Punch Mechanics

Power Generation
The rear hand punch can effectively be broken into 3 primary contributors to punching force: (a) the contribution from the arm musculature into the target, (b) the rotation of the trunk, and (c) the drive off the ground by the legs.(1)

-Arm velocity

-Trunk rotation

-Leg driving off the ground

Importance of Leg Drive

There is some conflict in current research as to whether leg drive or preimpact hand velocity is the greater contributor to punching power. Investigating other sports, which follow roughly similar movement patterns, the importance of the contribution of the lower body is seen throughout the literature. These findings indirectly support the conclusions about the importance of leg drive to develop punching forces.

Strikes with Footwork

There are two main elements to striking with footwork. They are 1) the type of step taken and 2) how the step is coordinated with the striking arm.

1) Type of step
There are essentially two types of steps used when striking: shuffling and shifting
a. shuffling involves taking small steps. The idea is to move without sacrificing your stance.
b. shifting is when you take a full step while punching. This allows for a great deal of movement but is also risky in that you are less balanced while moving.

2) Coordinating steps with the striking arm
There are two ways you can coordinate your step with the striking arm. Same side stepping and opposite side stepping.
a. Same Side Stepping is when you step with the same side as the striking arm.
b. Opposite Side Stepping is when you step with the foot opposite the striking arm.

Example: In this video the striker uses shuffling steps with same side stepping while moving forward and opposite side footwork while moving backward.
