The quiet time before a match I think players need to visualize and see how the game plan can possibly go. what they do is mentally go over the best things that they do ,like serve ,return approach and tactically prepare themselves for this match that they’re planning to play it’s important to Mentally get a good solid frame of mind before you attacking the match itself and I think players do that in the locker or before they warm up, so you set quiet time to reflect on your best skills to keep that positive attitude.
