I have many times talked about the motor learning concept of....the "action-perception gap" [or differential] regarding what athletes THINK they are doing. As opposed to what they ACTUALLY do.
Aside from the VERY starkly drawn "differential" between Sammy Sosa's on deck swings [wherein he JUST moved the arms/bat in an almost straight down trajectory] as contrasted with his ACTUAL game swings....
....there may be no better ex. than the comparison of Pense's on deck vs actual game swings. Here's a clip of the on deck swing:
[Slow it down to see how "unreal ", so to speak, it actually is ....compared to this:
I will not bother to try to qualify the stark contrast here. I think the differences should be quite obvious. The more interesting question is: How does one explain this stark difference?
Now, one argument that I have seen as regards such differences is along the lines of..."well, this warm-up somehow helps him do the right thing, so to speak, in real time."
But my standard reply ---one of 'em--to this line of thinking is: "If you saw a 12 yr. old warming up this way would you not be at least a little concerned?" Of COURSE you would!!
And you would very likely say this based on your empirical experience of seeing many hitters creating relatively poor warm-up or practice swings ...that pretty much MATCHED their ACTUAL game swings.
Which then returns us to the issue of trying to explain/understand as to how Pence can practice an utterly AWFUL swing...yet create a swing in actual performance that has yielded him millions of dollars!?
The following, I think, is the key. Based on research from academics like Howard Gardner ["Multiple Intelligences"], as well as my own personal and teaching experience I will say this:
SOME people have a GREATER genetic predisposition towards what can be understood as kinesthetic awareness [kinesthetic "intelligence" if you will]. Meaning that they have--at birth-- a much more refined POTENTIAL to discern movements.
Meaning that, compared to most, they can better discern thru "feel", what is good vs. not so good movement. In this context, it is CRITICAL to understand that this kind of "heightened" or sensitive feedback loop is almost ENTIRLEY ...TACIT....meaning non-verbal and not explicit.
The understanding [accepting] that this kind of genetic and tacit kinesthetic intelligence BEST explains the Pence differential [practice/explicit thoughts vs actual game swings/implicitly derived actions] really NEEDS to be fully considered.
Now, having said that, in effect, the Pence differential is best explained by largely genetic factors, does this mean that ALL elite level performance is simply a function of superior genetics?
Well, simply put....OF COURSE NOT! One of my all time favorite quotes [from a geneticist] as regards the basic genetic vs. environment question is: " Well I can guarantee you that performance is 100% genetics ...and 100% environment."
Meaning of course that there is this VERY complex interaction of genetic and environmental components that combines to create outcomes.
And thus, from my vantage point, as trainer/teacher, I see ALL potential development as something that CAN --via what I call " smart training"--be enhanced/optimized. Genetic factors, though important, are not the ONLY factors. MUCH depends on many OTHER factors.
And from my vantage point as a teacher very dedicated to the charge of developing true potential, my essential charge is to variously maintain the "high standard" that is almost entirely a function of a MERIT BASED mindset/approach.
Which means----and I DO want to emphasize this is this age of judging people by their immutable traits of gender/skin color----that I do not give a FLYING FUCK as regards your immutable traits!!!
My simple question is this: Do you REALLY want to engage in the relatively arduous process of learning how to move much effectively over time?
Do you REALLY want to engage in the process of doing what it takes to reach your true potential ?
THESE are my questions for you---as opposed to the kinds of utterly BULLSHIT nonsense that I all too often see writ large in the culture.
I can still remember [circa the 1970's] seeing the uncontrollable sobbing of some Latin guys getting released at the end of spring training. Never saw any Americans react this way. Why?
Because growing up where they did, they fully well knew the very stark contrast between the opportunities they might have here, vs. where they had been and now had to return to.
In a somewhat relative context, some of my most favorite guys to talk to about this country are cab drivers in big cities like New York. Asking them what they think about this country almost always yields an interesting insight.
As some likely know, I recently talked about some aspects of Ohtani's hip action e.g., hip displacement via eccentric [twisting action] loading causing a "forward by turning," Actions synonymous with "Paul's "pelvic loading." I want to add to what he says here.
I think he is certainly empirically correct in saying that for most elite level hitters, the degree of "separation" between the hip and shoulder rotation [unload] is minimal.
To say it another way, the differential between the hips starting to rotate and the shoulders starting to rotate is minimal. [I will add here that, yes, there is some degree of variability among hitters as regards this differential, e.g, Harper opens the hips more than Trout].
Last night I searched in vain [about 2 hrs. on my website] for an academic meta-analysis on implicit vs. explicit learning. I'm going to keep looking. But in the meantime here's a pretty good article about this [from a practical/teaching perspective].
An excerpt: "On the other side of the spectrum many self-taught athletes will often attempt to learn everything implicitly. The issue here is that without constructive feedback on the initial stages of learning bad habits will become permanent patterns in an athletes movement."
And: " Since you don’t know what you don’t know, you won’t be able to make the minor corrections necessary to continue to make improvements over the long term."
In a recent thread post I talked about Jim McClean's [golf instructor] concept of the "hip rise."
Here's a good slo-mo clip of Prince Fielder showing this [further slow it down via the .25 settings]:
Note the hip line change from relatively horizontal to the ground to much more DIAGAONAL to the ground from lead heel up to foot plant.
Also note---and this is very important---that though the lead shoulder "dips" [due to lead side lateral flexion] at heel up, by foot plant the shoulder line is more symmetrical [the "dip" is not there so to speak].
Go to about 2:31 of this clip of Ohtani:
[and slow it down to .25 using the settings]:
There are a number of functional parameters I want to emphasize.
1] Note the lead leg/knee "cocking" [internal rotation] at set-up [heel up]. Note that the FIRST movement from that point is the HIP action. The hips are counter-rotating [eccentric "twisting"].
I'm sure quite a few here have seen this overhead clip of Pete Rose done quite a few yrs back by Jack Mankin:
I consider this to be one of THE greatest clips ever that really helps to clarify what a high level swing actually looks like. Why? Well, one needs to understand the historical context of this clip.
Going back to around circa 2001 or thereabouts, aside from Paul Nyman's lead arm swing models, NO one had really shown this kind of clip of the relatively circular path of the knob from initiation to contact.
