Re: Re: Re: Re: Re: Fastpitch hitting -- Linear vs Rotational

> > > > It is sort of ironic seeing Arizona players as an example against 'linear' hitting, as coach Candrea uses the words "negative" and "positive" quite often when describing swing mechanics. Those words seem to be taboo on this site. I don't think any coach really tries to train athletes to move their hands in a straight line. It is elliptical if anything, neither pure linear nor pure circular.

His emphasis on negative/positive movement applies to the preparation phase of the swing which takes place prior to the onset of rotation. N/P movement aids in balance, timing, loading, and weight transfer; all of which facilitate rotational hitting.

We also use the very good information available on this site to understand more of the technical side of what happens in the swing. Both sources are useful and compatible. We have had way too much success hitting some of the best pitchers our state has to offer and winning championships to think otherwise.

A properly hit inside strike will involve little forearm extension causing hand path to be more circular and transfer more energy. A properly hit outside strike will involve more forearm extension with the hand path being a little less circular (but never linear), transferring a little less energy.

As forearm extension is introduced the radius changes, resulting in an elliptical hand path that is controlled by the amount of and timing of the extension. To create a purely linear hand path one must create excessive extension and drift forward or lunge during core rotation.

JTW,

Well said, but I think I want to focus more on the path of the sweet spot, not the path of the hands.

In either case I think we agree that the path of the barrel becomes more linear and less circular for a portion of the swing due to as you stated: "more forearm extension with the hand path being a little less circular".

Is there a combination of the two principles (rotational/linear) in a quality swing?

I feel strongly that there is.

Thanks for the discussion.

Jimmy
