Aroldis Chapman vs. Normal Humans

And the main reasons he throws so hard are that he's extremely closed at foot plant and has very long arms.

The release out front is because he throws pretty close to sidearm and has to release out front to throw strikes. The stride length is probably because he has long legs relative to his height.

Sultanofswat,

I see very little sports science being done here and since they went to Tom House for their information makes this a slam dunk.

Chapman throws fast because he has a high percentage of fast twitch muscle fibers compared to the percentage of slow twitch muscle fibers period. Did they mention this?
The fastest man ever was 5’9” tall, Steve Dalkowski.

When House started talking about the point where the ball actually goes forwards ironically he stopped the video right at this point , the acceleration phase starting at maximal outwards rotation of the Humerus (maximum forearm acceleration position) showed that all contractions before this had nothing to do with his velocity but they believe it does even though an acceleration graph proves them wrong.
They tried to portray his over early rotation of 30 degrees and his early separation as a contributing factor when none of this early rotation and separation happens during the acceleration phase and is used up during the transition from having his Humerus inwardly rotated moving to outwardly rotated. All pitchers accelerate with very little separation between the shoulders and hips, this is a fact House does not recognize.
When will House get up to speed on this information? I think because he had the pitching motion so wrongly diagnosed in the past that he is unwilling to admit his errors and keeps repeating them.

After all those great media graphics why do they not show a side view of Chapman to prove their contention that he releases 12 inches in front of his foot, I’m not saying he does not but nobody has shown this yet, while they still say it.

No, because this is gibberish. I have asked you before if anyone has (edit: MLB pitchers have) ever had their fast twitch fibers measured. I'm pretty sure the answer is no.

More gibberish. First, Dalkowski was 5'11", and he never measured faster than 93.5 mph - at Aberdeen Proving Grounds in 1958 (he said he was "tired"). My grandma can throw faster.

Sounds reasonable. Actually, I looked at 2 videos (but these were not using high frame rates) and it looked like he was releasing near his front foot.

People have had their percentage of fast twitch fibers measured. It requires a biopsy and is expensive and painful.

There is a very high probability that Chapman has a higher percentage of fast twitch fibers than most people including other hard throwing pitchers.

Man, you just can't post anything here anymore wthout someone getting trashed (in this case it was House).

Genetic Freak

TPM,

I’m pretty sure you are OK with the disinformation that the traditional pitching coaches bring around because you have to deal with it without the possibility of the good information being used by yours, but I’m not. This madness needs to be stomped out once and for good and Mr. House is one of the worst perpetrators of the injurious information. He needs to quit talking and selling his trash like he knows what he is talking about and proves it publicly often.

Sulty,

Nobody needs to be biopsied now to know how this physiological tenet works because the biopsies have already been done and studied to give us human performance answers.
It’s a fact no matter how hard you wish to disbelieve it.

YB, while you make lots of great points, you consistantly complain about being attacked, while you do it so often yourself here. The bottom line is, I see no reason to attack and insult another's philosophy, you did it on another post and now getting into Tom House.

No one else here has that priveledge of continuing to do so and remain.

I don't get it.

Yardbird- I don't like the way you say things. I don't appreciate the condescending tone you take in your posts or the complete lack of regard for anyone else's opinion. You are not the only person in this world that is right. You need to understand that.

At the same time, I do think that you know a decent amount about pitching. I can't decipher very much of what you say because most of it is ridiculous gibberish but the things that I can interpret actually do make sense to me. My best advice to you is this: Get off your high horse. If you disagree with someone, speak out in a way that makes you seem less Napoleonic and more like everyone else on these forums. If you disagree with a philosophy, rather than tearing it apart, why don't you actually give yours for once? 95% of your posts are badmouthing someone else, but you never provide any evidence as to why they are wrong and what you believe they should do differently.

Until you do that, I will never take your advice for anything more than used-up bandwith. It's nothing but hogwash and a waste of my time.

Are you saying the hips do not lead the shoulders, and there is no correlation between hip shoulder separation and velocity?

You can't attribute someones incredible velocity to one attribute. The fact that the kid is tall and lanky, probably extremely flexible, has an enormous stride, probably has more fast twitch fibers than your average joe, and uses mechanics that work WITH his body is why he throws so hard. If he was missing anyone of those features I guarantee he would not be throwing 105.

I actually have proof of Aroldis Chapman's release point, it's actually above his foot, not 12 inches in front.

I assume you mean you have proof that he has, indeed, at some point thrown a pitch released over his foot. I have several where he clearly releases well in front of the landing foot. I also have clips where he releases over the foot. Those are generally breaking pitches.
