These cognitive processes prepare the brain for success. Imagery strives on establishing a specific goal, in volleyball this can be imagining the flight of the ball to a specific player of part of the court. This may not seem achievable to begin with because any small discrepancies in the angle or speed of the hand will change the flight of the ball. Eventually, the serve will go where it was imagined to go, the brain then builds links between the action and imagery.
This makes performing the serve far easier if it was precedented by imagery. A world champion golfer, Jack Nicklaus says “I never hit a shot, not even in practice, without having a very sharp in-focus picture of it in my head.” The fact that professional sportsmen are using imagery reinforces the validity that imagery can drastically help one’s performance in sport. MethodImagery was used in an attempt to increase performance while overhead serving in volley. Imagery is visualising a movement before performing, this mentally prepares you to execute the move correctly.
To test the influence of imagery I performed 10 serves without any mental preparation and 10 serves using imagery.
