The better you concenrate, then, the better you seem to play. You become more alert to what is happening around you, because your attention is now undivided. Without concentration, coaches say, no athlete can be successful. In sports, concentration is the focusing of your attention on the task at hand, excluding anything not pertinent to the task. Concentration in sports is deliberate and controlled and done under pressure.
Pressure can cause anxiety, and anxiety is a distraction.
Therefore, concentration can be utilized best when you are relaxed. Rehearsing your moves mentally and physically will improve the quality of your performance. Mental Rehearsal or using Visualization gives you sufficient practice at imagining yourself making the play. Your muslces will subtly respond to your thoughts during a game and simulate the motions automatically without your being aware of it. Simply, translate the instructions you give yourself into images in which you body carries out in your mind.
