I agree with most of what jdfromfla says below, except his ultimate answer of "No." I think the correct answer is Maybe. J-bands, flexible tubing, the Throwers Ten and similar programs can, in some cases, increase velocity. As jd points out, there are many factors involved in velocity. IF, I repeat IF, a pitcher has weakness in the shoulder, or any other part of the kinetic chain, conditioning of that area may increase velocity. You're only as strong as your weakest link.
Bottom line is you ought to be on some sort of shoulder program, whether it helps your velocity or not.

No but they will condition your arm and shoulder so that when you do increase velo you won't injure yourself...or at least have the arm in the best possible shape for the increase.
Velocity increase is a holistic thing..better mechs, more strength, improved conditioning, positive mental attitude, desire, determination all play a part, the bands have a place within that.
This is all after your growth spurt..many guys increase velo by just getting older..passing puberty and becoming more of a man than a boy.
