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.
As regards ALL that I say .....uh, well, NO!!!
Here's a clip of Derek Lee:
englishbeyhitting.com/videoclips/dle…
Where's ANY of the above "theories" being realized?
And to those who might argue --somewhat logically--that this single example is not an ideal representation of what most MLB hitters do I will say this:
For every MLB example one can show that one thinks represents some of the above examples I provided, I can show at least 10 MLB hitters who basically approximates the kind of relatively "quiet" /non -dynamic loading that Lee exhibits.
Why do I say/argue this? Well, because I've spent 20 yrs. and well over 20K hours looking at elite level hitters!! Literally!

...."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.

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!!

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].

About 10 yrs. ago in my obsessive search for good info about "how the body works" in the context of swinging a bat, I ran across a retired physician named Jeff Mann. After retiring he turned his attention to trying to understand the golf swing.
The link to his site: perfectgolfswingreview.net
I'll quickly add a couple of points before going further: 1] I did then and do now now understand that there are some pretty clear DISTINCTIONS between a golf swing and a baseball swing.;2] I have never swung a golf club.
Growing up when and where I did [basically Pasadena Tx in the early 70's] ,if you were caught playing golf or soccer, you were likely to get your ass kicked!!

Those who are pretty familiar with "my stuff" know of my thoughts as regards how I think focusing on the lead arm/torso linkage is a potentially KEY method in overcoming many typical flaws, e.g., bat drag, back arm pushing tendencies, poor rotation, poor swing plane.
Here's a golfer swinging with just the lead arm:


He hits the ball about 300 yards. Note the alignment of the lead arm at the peak of the takeaway, initiation of the downswing, and at lag. It is tight along the shoulder line and perpendicular to the spine.
This kind of geometry [alignment] is VERY similar to MLB hitters! Why is this good?

I recently received a msg asking about a recent tweet as regards the back leg flexion action. An action, I argued CAN help facilitate ["free up" as I sometimes say] the hip rotation.

To the clips I showed already let me add 2 more:
As regards the action of the back leg ,both are similar in that both show a good deal of knee flexion AS the lead heel starts to go into foot plant.
