Imagery is useful for refining or improving your present physical skills. Repeating the performance of a skill mentally stimulates and refines the nerve pathways used in that skill's execution.
Imagery is an ideal way to learn and practice strategies for an upcoming competition.
Visualizing every game situation is the kind of mental practice that provides you with extra practice in preparing your upcoming strategy. This is especially useful in preparing for situations which you may not be able to simulate in practice due to lack of time or lack of facilities. Imagery allows you to accelerate the healing and recovery process, helping the body repair both the minor damage sustained in daily training and the more serious trauma experienced during injury. By creating and maintaining a mental image of the body in perfect health ,or of an injured limb regaining its strength and range of motion, you direct the immune and circulatory systems to produce that outcome. Imagery can be used to develop the confidence necessary to break through to new levels of performance.
