Well, I don't want to go into the weeds too much here [again twitter ain't the place for in depth shit!!], but here's something from Paul Nyman yrs. ago [which I read then] on elastic energy:

setpro.com/forums/showthr…
Within this he cites some research about elastic energy. The entire article is relevant/interesting. But there's one key phrase I have found to be VERY interesting [over the yrs since I saw this --around 2001]:
"Research has shown that by increasing the speed of the stretching phase and resisting the stretching movement by applying greater tension in the muscle(s) being stretched, there is an increase in the storage of elastic energy."
I think the key thing here is as regards the part saying..."RESISTING [my emphasis] the stretching movement."
Mel Siff referred to this kind of muscle action as "quasi-isometric/eccentric" muscle tension. Later, I ran across something I think is very similar to this kind of movement/muscle action potential.
Something the pretty well known biomechanist Stuart McGill referred to as "superstiffness." A concept he developed via analysis of emg firing patterns of elite level athletes.
Here's something he wrote about this concept:
backfitpro.com/pdf/Enhancing_…
And here's a short you tube clip providing a little insight into this concept:
What all of the above is hinting at, so to speak, is that an athletes ability to effectively REACT or respond to disequilibrium effects [caused by movement dynamics that disrupt equilibrium], is one of THE keys to creating optimal complex ballistic movements.
I would only add here that many of the kinds of exercises I have worked at for many yrs. developed specifically for throwing and swinging, are most certainly informed by the info I cited above!

Aw yes. J.R. Richards. I want to say a few things ---from personal experience ---about this remarkable athlete.
I first saw him in the lunch line in spring training [circa 1972 ]. I was right next to him in the line and my first impression was ..."DAMN look at the hip to shoulder ratio ...this guy --at 6'8"-- is built like a damn bodybuilder!"
As a 17 yr. old guy, who was pretty well recruited for college football I had been around some pretty decent physical specimens. But I had met NO ONE quite like J.R. in terms of physicality.

Here's a DAMN GOOD! ex. of the lead side functioning really well [lead leg/lead hip]:

[Also, this is a damn good ex. of a no-stride "twist/untwist" wherein the lead leg and back hip internally rotate to load].

Note the lead foot/knee landing "square" to the plate as the leg reverses the internal rotation. This alignment best approximates the "athletic position".
This leg posture facilitates greater stability [as opposed to opening --external rotation] of the femur/knee. It also creates greater potential RESISTENCE against the hip rotation.

Patrick asks a good question here. I want to try to explain some of the factors involved in his correct conclusion [as regards those having "an advantage."
Here's some of the factors involved in being able to create effective adjustments:
1] Your best swing is a function of very efficient loading/unloading, i.e., using my simple construct of a high level swing, you know how to create very good bat/body alignment ...
.....from initiation to contact. And you know how to create very good hip to shoulder rotation [this entails speed, magnitude, timing of this trunk rotation].

I recently had a DAMN GOOD! conversation with a pretty young guy 30 yr. old [relative to my age!!] Close to 2 hrs. Why do I think he is destined for a damn good future?

A few points about that: 1] He knew about Mel Siff and his books. To me, that was very impressive.
Mel Siff is arguably, THE finest sports scientists in the last 100 yrs.
2] I was talking about a book explaining body resistance exercise and he quickly cited it ["Overcoming Gravity"]. DAMN!! He knows Mel and this book!!

Well look, I ain't all up on why one loses followers on twitter. I do see that I lost about 8 people after I posted about a former NYT reporter talking about the assault on MERIT.
My response? Well, if you don't like me quoting a liberal talking about the ILLIBERAL aspects of degrading meritocracy, I say good riddance!!
And I would further add that if this is the reason you decided to "un follow" me then I would say that this is perfect proof that you lack the intelligence to really benefit from this twitter account!!

I briefly mentioned this book last yr ["Overcoming Gravity"]. This is a VERY good inquiry into the value of body weight exercises. VERY much relates to the kinds of exercises I have developed for hitters/pitchers over the last 20 yrs.
Here's the article I cited last yr:
stevenlow.org/the-fundamenta…
I want to highlight a few points from this article:
"Impressive levels of strength that can be built by using bodyweight strength training for the upper body as the progressions require excellent proprioception and kinesthetic control. "
