Not enjoyed !!! But will contribute.
It should read:
The inverted “W” as witnessed at glove side foot plant increases the valgus stress on the MCL (UCL) later at the beginning of the forwards acceleration phase because of it’s timing issue and pronation of the forearm during the acceleration phase eliminates ballistic bone crash within the elbow.
When you finally understand this you will actually help youth pitchers eliminate the pathologies they produce with this mechanical timing and forearm action!
Understand that no forwards acceleration can start until the Humerus has reached outwards rotation to some degree and best at full range of motion and at length.
It pretty much has been Kinesiologically proven that by not performing outwards rotation of your Humerus during your pendulum swing phase to arrival to full range of motion or at least 50% of outwards rotation during this phase as does Kershaw and some others that you will then perform it much later and much more violently by leaving your forearm down (pronated) with hand on top. This action has you attain full range of outwards rotation of the Humerus during the separated rotational acceleration phase leaving your arm then intuitively off to the side and bouncing backwards Pliometrically and not allowing you to perform the forwards acceleration phase during much the rotational acceleration phase, negating much of it’s shoulder rotational length during drive.
This action later micro tears your MCL with each pitch until it finally gives way.
Notice, Wolforth as I did, calls you out on this because we know Kershaw passes through “w” and arrives with his Humerus in almost the right position partially outwardly rotated (shoulder external rotation) at glove side foot plant. You again with video now actually stop the video with Kershaws leg still up during drop in, just to prove your point. Try stopping the video when the foot firmly plants (not at the beginning of touch) and the walking response triggers when it counts in the principle. You can fool most with this technique but will not get away with it with me and some others.
So, repeating this false information means you do not learn or understand, I still have hope for you especially sinse I now know you are a dad also. When you see him intuitively supinate (if you recognize it) I guarantee you will do something about it.
Why don’t you tell us all what Nymans exact definition of the term means and when it is performed when weighing it against when the glove foot firmly plants since you or any others including Paul ever does this for clarification ?????? Please! Or have Paul do it because he runs from my posts if I ask him.
By posting the stills you did at many different foot plant timings leaves people thinking you know what you are talking about when you have no point of reference that shows you do and why you don’t really understand the controversy. Pitchers can actually pass through the inverted W and arrive with your forearm and Humerus also outwardly rotated at foot plant almost correctly to avoid hard Valgus bounce and drive from more directional length.
Do you understand range of motion? I think not. Do you believe in stills, I believe you do and why you continually get this wrong just like House and his followers.
Dr.Marshall’s argument has nothing to do with recovery phase “involuntary pronation snapback.” If you do not understand this why comment on it ?
Dr.Marshall wants forearm pronation from supination full range motion at the start of the forwards acceleration phase. This protects at 2 points of Kinesiological action. First it stops the elbow from crashing together from ballistic hyper extension from supination. Second it contracts the muscles of the flexor mass that pulls the ulna towards the radius relieving stress across the MCL during drive and start of drive.
This is reason enough to teach it to little Rex. Mother would if she knew the information!! Maybe you are incapable of this protection like most type “A” males?
Please explain to us all why you have dumped the anti-pronation article 3 and 4 by Paul Nyman? Don’t tell me he is afraid to go on record or actually learned the truth ? Maybe because O’Leary agrees with Dr.Marshall on this, he can’t? What a shame, I really would like to read his thoughts on this important principle. What are we all to think now?
The word you are misusing here is “forceful” although it is also forceful, the Kinesiological word is “Voluntary contraction” or just voluntary. It is just one of the many tenets. I know you know the right verbage but can’t bring yourself to use Kinesiological terminology taught to you by Dr.Marshall that is correct.
Who cares this is not the principle that is being explained! Only voluntary pronation of the forearm during the forwards acceleration phase eliminates drive pathologies. This is just more fog that does not pertain, you guys like to throw out. You and others contiually get the timeline confused and misunderstood.
To bad the sport psychologist Dr.House did not understand the same things all these other commenter’s like yourself need to understand before making misleading observations. You giving House any credit on this is laughable. Get it right!
Boy you take the cake for disinformation (apparently), like others who do not understand the information. I guess being the president of the Marshall haters club has it’s drawbacks?
The Kinesiologist Dr.Marshall only explains it’s mechanical actions in understandable detail, he also explains the opposite action (antagonist) supination during the acceleration phase and claims no ownership, how could you possibly get this wrong? Explanatory Kinesiological discovery within a particular mechanic is valid and has merit. Marshall is not talking about recovery pronation!!!!!!!!
Dr. Marshall did not throw a curveball of any kind, he was taught how to throw one and broke two ribs because of it months later by trying to “pull down the shade” and gave up on it early and long before his research. This injury is probably what drove him to the research along with other senarios. He was an all star Short stop most of his minor league career. He did invent the pronated curve while an NCAA head coach and professor of Kinesiology.
Why imagine? when he tells you and shows you right when he did the research at Michigan state in the late 60ies and early 70ies that proved it’s efficacy with the first of it’s kind High speed film (500 frames a second) that also employed the first strobe assist that is still used today by others like House. This makes him a pioneer in the field although he has to battle against the arrows in the back by you and others.
Thoughtfully or not he is wrong and so are you by repeating your acceptance of it.
Let me explain what you are actually seeing so you can finally understand what you are all missing. Lantz pay attention here if you really want to learn these mechanics as you say you want to at your site.
When viewing high speed video you can observe drive forearm rotational (non-injurious) pronation, nominal forearm position (injurious) and supinated forearm (injurious) rotation.
When you perform any of the 3 your forearm recovers in pronation because it has no other place to go and is involuntary. Involuntary means there was no conscious contraction to cause this.
When you intuitively (youth) or voluntarily (youth and adults) supinate your forewords acceleration phase (curves, Sliders, Cutters and some fastballs) your thumb flies up and your elbow goes forwards then down during the phase having your elbow run out of range of motion meaning it can go no further in it’s extension range of motion and slams the olecranon process into it’s Fossa on the epicondyle with ballistic force in hyper extension long before the witnessed and incorrectly explained next action. The very next action that you all mistake as voluntary pronation is actually “Involuntary pronation snap back” after release the other way after the injurious crash that we are trying to get you all to understand.
When you pronate your acceleration phase correctly you also maintain pronation and you will see the elbow pop up Like Lincecum and Kershaw at release and recovery. The elbow does not crash with this mechanic and can be produced with all pitch types if you learn them and are much more powerful and lengthy.
You have this right in that O’Leary a novice like Nyman e-mailed Dr.Marshall and had this explained to him in detail, just as Dr.Marshall explained in person to Nyman why this mechanic is problematic. O’Leary now had something to say while standing on his novice soap box and took full advantage of it to come back at Paul because Paul called him something derogatory in public, meaning this is just a feud between a novice and a rank novice on the subject and in the same way you e-mail Dr.Marshall with your very rude and always incorrect assumptions and he always answers you with class and dignity that really gets to you, so you write these negative comments when ever you get the chance.
Who does this remind you of think?
Who does this remind you of Paul?
O’Leary is your clone and probably got his enthusiasm by reading your non-sense. He is your creation. At least he gets it half right sometimes.
The same can be said of your sycophant frustration of Dr.Marshalls continual mechanics bashing of the admitted and original PED’S user Tom House (your guru) because of his very minus FB.
It’s very understandable for those of us who know the truth and have been around a while.
