As I have written about in some detail on my website over the yrs., the notion that elite hitters are creating "lateral trunk tilt" or "bend" [flexion along the frontal plane] so as to create "adjustability" is largely incorrect.
From my vantage point, this is a misinterpretation of what is ACTUALLY happening. Now I should hasten to add that there are many joint/muscle combinations that can be and are utilized to move the body to swing a bat.
BUT. My frame of reference here is that of thinking in terms of optimal efficiency and the maximal transfer of momentum from body to bat. Regardless of location.

The following may seem off topic [to this site] but I think otherwise. Over the yrs. there has been some discussion of implicit vs. explicit learning in the context of swinging/throwing.
Though not exactly synonymous with this bifurcation [but related] is the notion of internal vs. external focus.
Wulf et al argue that an internal focus is superior to external focus. I disagree. Simply put...."it depends" [a Mel Siff quote that does apply in this context I think]
The following ex. ---that comes from drummer Marco Minnemann and bassist Mohini Dey---is an example of a learning process which COMBINES implicit/explicit learning and internal/external focus.

As most know twitter can be a cesspool of idiocy and viciousness. On the other hand, in trying to find info on the virus and the politics thereof, I have been very impressed with numerous people. I recently ran across one such person.
The context is the growing empirical info as regards athletes [especially male it appears] and the vaccinations. This info has now reached to a level of concern among some doctors/researchers.
"George the Puppy" has spent of good deal of time objectively looking at this info.
The link:



I have read thru a number of these. Including the link to Dr. Campbell [British dr.] who explains this potential problem well as he does with other aspects of the virus. In totality these links make a pretty strong argument for some concern.

And let me add to today's entry one more heretical notion. Some yrs. back someone asked Paul Nyman as to what he thought about the newfound interest in quantitative analysis applied to baseball player development.
His reply was along the lines of ....it's kinda like giving the nuclear bomb to Eskimos.
In this context, last night I spent some time looking at various instructors citing the great value of the Blast Motion metrics/analysis. But. From my vantage point, here was the problem:
Not a SINGLE hitter I saw being cited as greatly benefitting from this analysis conformed to Paul Nyman's "building code" of HIS description of a high level swing, i.e., good posture, connection, rotation [PCR or PCRW]. THE standard I know well and utilize to analyze hitters.

I have stated MANY times over the yrs. [starting about circa 2002] had hitting instructors spent as many hrs. as I did [thousands of hrs.] looking at and coming to REALLY understand the info from Paul Nyman at Setpro, the "culture of instruction" [my term] would be more advanced.
As an ex. of this, I'll cite this attempt to analyze Griffey's swing:

Now I should hasten to add that this explanation is not a horrible analysis. The author does seem to understand somewhat, the kind of of postural dynamics Griffey creates.

Within this it says that ..."the value of the extension torque is quite small." IF you have an understanding/appreciation of the the complexities of ballistic/dynamic THIS statement is VERY revealing.
Here on twitter [and on my cite in much greater detail] I have talked about the very important concept of "interaction or motion dependent torques" wherein joint actions at joint A or being driven by joint actions that are NOT anatomically connected.
Understanding this is, I think, one of THE most important considerations that one needs to understand in terms of REALLY being able to accurately assess and ultimately effectively TEACHING movement development.
