How Can Swimmers Benefit From Visualization?

From the Swimming World website...

As many swimmers are currently in the throws of championship season, here is one way to rehearse a race without getting into the water.
Visualization is, quite simply, sitting yourself down, closing your eyes, and thinking (or rather, dreaming) about your swim. This mental rehearsal is a cognitive technique to mentally stimulate certain aspects of an athlete’s performance. It involves attempting to create clear images of desired outcomes and encompasses other elements such as executing skills, implementing strategy, and regulating emotions.
