Wasnt real sure where to post this…

I was reading this article about the Concept 1 shoes:

and came across this paragraph:

In fact, when it comes to jumping higher, you can usually do it merely by learning proper technique. Dan Barto, a player development specialist at IMG Academies in Bradenton, Fla., who works with a number of NBA players, says when he work with athletes he begins by aligning their bodies on takeoff. “We look at the imbalances and strengths,” says Barto. “Some players are god's gift and their calves fire perfectly and their quads fire perfectly and on up. But usually our strength coaches, if they spend one hour teaching alignment, can probably increase a vertical by three inches or so.”

What does this mean? Is it true? And how can I find out more on how to do it?
