Most players focus on running to the ball quickly when practicing movement. Being a fast runner is helpful on the court. However, recovering and anticipating the next shot will be much more effective than relying on your speed running to the ball.
Immediately after the follow through, you should regain your balance and move in the direction of the open court. Most players at all levels will hit the next ball towards the opening three out of four times. If you show your opponent that you can cover the open court, it forces them to either hit the shot better (higher risk) or try to hit the ball behind you. This will be frustrating for your opponent and should result in more errors.
In addition, this idea will allow you to get to most of the balls sooner on your end, and usually result in your shots being more effective. Covering the opening and anticipating your opponent's next shot are the keys to efficient movement on the court.
