...."centrifugal force-induced elbow extension motion"..
This statement very much relates to what I have talked about MANY times as regards the concept of "interaction" or "motion dependent" torques.
Meaning that from a CAUSAL perspective, joint actions you see ---and THINK --are a direct result of that joint, are, in fact, THE RESULT of OTHER joint actions [typically happening at a more proximal region to the hips or trunk].
From both an analytical and teaching perspective, this understanding is vital in terms of understanding how the body actually works in the context of swinging/throwing.

Over the yrs. I have had the great fortune of meeting dads who really wanted to learn how to help their sons or daughters reach their hitting potential. One such individual is Stu Byrne.
An engineer by profession, he did a remarkable job of using his engineering eye to learn "my stuff." He had a remarkable way of taking my words and creating DAMN GOOD! visual interpretations.
He created MANY clips--including quite a few still sequence clips which many on my site really liked:

Here's a Bonds ex.[I hope this shows up well]

A good example of one of the 4 basic ways to create what I refer to as EFFECTIVE loading [hip flexion/"dead lift-like" loading [my term]:

englishbeyhitting.com/forums/index.p…
Note that at set-up the head is behind the knees. But by foot plant, the head moved away from the knees [and towards the plate]. Like what happens in a stiff-legged dead lift ,ie., hips are pushed back/head and upper trunk react by going the opposite direction.
This, of course, starts to set-up the swing plane and it serves to create eccentric/isometric tension in the posterior chain [hips, erectors--lower back--and back leg musculature].

Most familiar with my teaching, know that I emphasize --and have numerous drills/exercises forcing this--keeping the upper lead arm very tight to the body. The reasons for this mandate are both biomechanical/physiological and empirical [observing elite hitters].
An example of the latter is this clip of Prince Fielder:

Go to 12:22 [and slow it down even further via .25 setting]

This is a terrific example of what I refer to as keeping the upper lead arm very "tight" to the body.

I grew up with 2 hitting idols: Williams and Aaron. I heard back then that Aaron had quick and powerful wrists. Thus I did I shit load of wrists curls starting when I was about 9yrs. old [I used a small wooden bar with a rope and weights attached].
I will say that, as a result of this, to this day my forearm musculature is pretty damn impressive!
But. As it turns out --as I learned yrs. later [and unfortunately after the fact ,i.e., dammit Paul Nyman why the hell could you not have been born yrs earlier!!]
the wrist strength ain't got much to do with how Aaron did what he did!!

Over the yrs. I have heard from many that one needs to create alot of dynamic loading to create a high level swing. These arguments have taken many forms over the yrs. e.g., "one needs to create "the move" [really amounts to simply creating some degree of eccentric --twisting
..of the hips]. Or, one HAS to create a "running start" of the bat [what ever that means exactly!!] Or, that one needs a dynamic leg kick [ok...I see...lifting--flexing- the lead leg will, ipso facto, create a high loading/high level unloading.
Or, a high level swing is primarily a function of variously manipulating the back arm ["top hand torque", proper "slotting", some kind of ill -defined "snapping" of the back arm]...etc,etc., ad infinitum.

Years ago, I ran across a quote from the great sports scientist Mel Siff that I think is a very simple but effective analogy explaining complex ballistic activities like throwing/swinging.

He said: "Complex ballistic sporting activities are like a symphony of muscle actions."
The implications of this are at least 2-fold.
It implies that complex sporting behavior of movements and muscle action create a kind of synergy that is greater than the sum of the parts.
BUT. It also implies that if even one of the components are "off" in some way [think of a tuba going off ill-timed for ex.] the overall sound of the will suffer [potentially quite a bit].
