Slider vs. Curve ?

Not shoudler.

well the day after you pitch i believe there should be some soreness, and i say some, on the fat part or extensors of your forearm and some tightness or soreness in your bicep. atleast that is with my experience. i threw a slider for about a year and quickly put it away because i started experiencing elbow pain, not an acceptable place to be sore. but if someone is to throw breaking pitches and fb.s, who is to say that their arm pain is not the result of bad fb mechanics?

Supination is likely to lead to elbow pain. The slider requires supination. Some pitchers also supinate on their curve (using incorrect mechanics).

Explain once again, to a pro audience, how you don't supinate on a curveball...

You also say a slider REQUIRES supination, shouldn't these be opposite?

After pooling ELEVEN pro pitchers, ELEVEN say... supinate curveball. (ie KARATE CHOP).

This poll was done under VERY scientific circumstances!!!

The curve should be thrown with the palm remaining in the same plane as both bones of the forearm. No twisting of the wrist (e.g., supination). Very straightforward.

The slider does require supination. That is what makes it a slider.

You misunderstand the definition of supination. A karate chop is not supination.

Supination: Rotation of the forearm and hand so that the palm is up, as opposed to pronation.

From the pitcher's perspective, for a RHP. The palm starts facing forward/down. The palm rotates clockwise, so the palm is now facing up.

With the "karate chop" (again, from the pitcher's perspective for a RHP), the palm is facing left (perpendicular to the ground) and remains facing left. It does not rotate clockwise or counterclockwise from the pitcher's perspective.

So well said Tex. Suppination on a curve can lead to forearm or elbow problems.

Well, technically, the hand/wrist must be in a supinated position to throw a curve. The key is to supinate before the arm starts forward such that there is no further supination while the arm is going forward. In other words, do like Ron Popeil says in one of his infomercials: "Set it and forget it".

The twisting and un-twisting under the force of acceleration and deceleration is what causes problems (along with simply throwing too many curves).

Isn't it practically impossible to throw a curve without any supination? When I think about how I throw my curve I guess I never really thought about what I do. Anybody got any good clips showin the right and wrong way to throw curves?

I don't get the point you're trying to make.

As long as we agree on karate chop.

The karate chop is one way to put it. As Roger has put it, set it and forget it. Suppination as a position of the arm, but never during accelaration of the arm.
