The development of a mental strategy (simulating elements of an impending performance) via mental imagery can be very helpful in promoting an athlete's best performance state both before and during a performance. Properly practicing the necessary mental skills can aid in triggering a network of neuronal encoded programs that enhance the brain's nerve pathways that regulate the proper implementation of the skill.  Before an athlete's event or competition, gathering imagery of past successful feats might help keep confidence levels up and help reduce nervousness before the performance. It is important to encourage athletes to construct vivid mental images by using all of their senses. When it's feasible, this can also involve physical movement to connect what's being pictured to the motions needed to execute the skill.
