Abstract
[Purpose] To clarify the relationship between motor imagery ability evaluated using 3 different methods and performance changes representing the effect of mental practice (MP). [Subjects and Methods] Twenty healthy students performed a motor task before and after MP to examine changes in their performance as an outcome of such practice, using the Movement Imagery Questionnaire-Revised Japanese Version (JMIQ-R), mental chronometry, and mental rotation for the evaluation of motor imagery ability. Subsequently, the relationship between performance changes and the effect of MP was examined. [Results] The students’ levels of performance markedly improved after MP, revealing a moderate correlation between mental chronometry results and the amount of change in performance. [Conclusion] Mental chronometry-based motor imagery ability may be associated with the effect of MP.
