Motor imagery is a type of mental stimulation that involves focussing and imagining motor actions (movements). The technique of motor imagery is used in athletic training programs in order to aid the athletes to visualise the motor skills they are required to use for their given sport. The theory behind motor imagery is that the mental planning and anticipation before an event work to mentally prepare an athlete, both mentally and physically. Motor imagery induces physiological responses in the autonomic nervous system including release of adrenaline, elevation of heart rate and blood pressure.
