Question

Does a jockey have any control over how well a horse jumps out of the barriers?

Answer 1

Sure. It is the jockeys job to make sure the horse is focused and on his toes for a good break from the gate.

Answer 2

Of course they do!  One of the jockey's responsibilities is to help the horse get out of the gate in stride and in the position the jock wants.  A jock on a frontrunner will try to key the horse up and make sure he's paying attention so that when the gates crack the horse is ready to go.  A jock who doesn't want to be on the lead will try to keep his/her mount calm in the gate.  A jock is also instrumental in helping correct the horse if it encounters trouble (either falls or makes contact with another runner) leaving the gate.
