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.
"Konnakol" is an EXPLICIT Indian method by which one learns rhythms via a type of counting method. Which Mohini is using here. Marco is keeping up, so to speak, due to the fact that he has spent thousands of hrs. practicing ----EXPLICITLY ---all kinds of sticking patterns.
In other words he has learned [and so has Mohini] EXPLICIT RULES as regards rhythms/movements. These explicit rules become internalized over time [implicit learning]. Such that he does NOT need to think [explicitly ]about the movements.
Thus, in this ex. he only needs external focus, i.e., reacting to and working with the rhythms/structure of this specific musical construct.
Said another way: He is expert at doing this kind of manipulation of mind/body in this context due to spending thousands of hrs. learning both explicit rules and internal focus [the latter amounting to knowing he needs to move EXACTLY LIKE THIS in time and space].
And developing precise feedback [audio and metronomic feedback] to check his precision.
ALL of what I said above, can be variously and creatively applied to learning how to develop better throwing/swinging. I know this not just theoretically but empirically [yes I have tried to apply these thoughts to teaching hitters/pitchers].
And for those who may not know I have variously practiced playing drums for over 50 yrs. Thousands of hrs. --both practicing and listening to many drummers over that time.
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.
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.
I want to make a few comments about "those who studied House [circa 2000]". I was most certainly around when Paul started critiquing some of House's info starting around 2001.
I bought Tom's bk. [1st ed.] on pitching mechanics. So, I am VERY aware of Tom's concepts such as "find the balance point" and "pause at the top." What struck me in these pgs. was an example of ---allegedly --- being ..."out of balance."
An ex., in other words of some type of inefficient postural/loading dynamics. The ex. he cited was Ron Guidry. Now, for the uninitiated Guidry was maybe 5'11" and 160 lbs. And he topped out at....98MHP!!
I've known Justin since he was about 14. I have worked with him via my website as well as a number of times in person. A VERY good student, i.e., very focused, willing to listen, highly motivated to improve, and works at it in smart ways.
"Very focused". I saw this the first time I worked him in person. Prior to actually hitting, he did a dynamic warm-up routine with the kind of seriousness, focus, and precision that you almost never see from athletes. I said to myself, "this guy's gonna be fun to work with!!"
Though not a big guy, he definitely was [and is] a guy who you know has the intent to swing hard. I worked with him over these yrs. to develop slightly more precision of movement and he has worked at this well I think.
