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.
Thus, from my vantage point, these metrics may well be measuring/quantifying SOMETHING, but it is not at all clear to me that it is measuring the kinds of functional characteristics I consider highly relevant.
And it was --based on these you tube ex. and numerous others who advocate for the Blast Motion that I have elsewhere seen---blatantly obvious to me that these instructors really do NOT understand a high level swing or how to teach it.
And of course I will add that anyone who wants to challenge these assertions on my part should feel free to do do so. I think most should know that I welcome rational discourse/arguments/challenges!
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.
Let me add here as to the dubiousness of the concept of "riding the back leg" the fact that I have been talking about "cues vs. reality" for over 15 yrs.
The quote of "cues vs. reality" comes from Paul Nyman around 2001. That's about when I first ran across his website. He caught my attention with 2 articles. One was entitled: "Momentum is the most misunderstood thing in all of sports." And: "Cues vs. Reality."
In which he argued that the cues that many instructors use do NOT really describe what hitters/pitchers are ACTUALLY doing, i.e., the cues do NOT describe the actual "underlying realities" that actually create high level movement.
A few yrs. back I was working with a young hitting instructor in the context of trying to help him become a more effective instructor. He was working with a hitter and he kept saying to this hitter..."you need to sit more."
I stopped the instruction and ask the hitter: "Do you actually know what he means?" And the hitter said: "No, I really don't." I then ask the instructor to SHOW the player what he meant.
And what the instructor showed him--from my vantage point of someone who was THE guy who originally defined this term yrs. ago in detail [based on empirical observation AND thousands of hrs. of personally practicing movements],was NOT an accurate description of "sitting."
