Effectiveness of motor imagery on performance and sport success is mutually affected by individual ability to form mental images. The aim of the present study was determining the effect of imagining the play strategies in comparison with imagining the skills on performance during a sport competition course. Participants were 30 (19 men, 11 women) karate-kas who were evaluated upper than moderate in terms of performance level. In the beginning, participants' ability and past experiments in motor imagery were assessed. Then, they took part in a semi-experimental design at the one of three strategic imagery, movement imagery or control groups. Each person immediately after combatting with an opponent performed the asked action depending on the group and finally competed against the same pervious opponent, again. The results showed that karate-kas had excellent imagery ability, especially in preserving the movement temporal characteristics, and at the past competitions, specifically prior to their matches, they had used both cognitive-general and cognitive-specific imagery. Also, nonparametric analysis demonstrated that in the semi-experimental design, strategic imagery group gained higher point difference during posttest, though skill imagery or control group did not differ significantly. Indeed, the research findings revealed that strategic imagery has more advantages compared with skill imagery, suggesting that imagining the strategies of play can be used between the matches as an effective factor on sport success.
