Combination Effect

 

What is Combination Effect?

Combination Effect is not a swing method. It’s a method of identifying and correcting a swing based on player’s current state of ability. C-Effect is based on a simple formula that can apply to any type of swings and it can reason as to why certain elements or movements can work for some but not for others.

The general idea of Combination Effect is that every swing is to follow combination of two swing elements. 

The main focus of Combination Effect is to develop player’s ball striking ability. Improvement in distance is secondary and only a subsequent effect to this theory.

Theory of Combination Effect

  • For every action, there has to be a counter action on the opposing movement group

In other words, it's not enough to focus on one movement group. There has to a counter action on opposing side of movement group to negate the first move for such movement to be effective.

For example, a shoulder turn has to be negated or countered by hip rotation for such swing to be effective.

  • For every non-action, there has to be a corresponding non-action on the opposing movement group

In other word, if there is an immobile or inactive movement group, opposing movement group cannot be active as well.


For example, if a player lacks shoulder turn then the player must inactivate hip rotation as well. This is not a “good” swing by any means yet it can immediately nullify the inactive shoulder and the result can be a better ball striking. The reasons are to follow in the next sections.

Movement Group

Opposing Movement Group

Why is this important?

If a player has a mobility issue and wants to progress one's swing without improvements to one’s fitness, this method of teaching can identify and correct or at least provide immediate solution to negate one's false or non-action.
