The Effect of Type of Task and Body Fatigue on the Ability to Mentally Imagery Skilled Athletes

The purpose of this study was to investigate the effect of one type physical fatigue on the mental imagery ability in skill athletes with emphasis on duration of movement. Thirty skilled athletes were randomly assigned into two groups of fatigue and control. Pre-test and post-test measures included internal vision external and motor vision. The experimental group performed the exercise protocol for fatigue (running at 70% of maximum heart-rate until fatigue), while the control group did not do any physical activity. The results revealed that one-part fatigue significantly reduced the accuracy of imaging. In both tasks, the accuracy of external visual imagery was higher than that of the internal visual imagery, and the accuracy of internal visual imagery was higher than that of the motion. Also, fatigue did not have a significant effect on clarity of short and long task mental imagery. Finally, fatigue had no significant effect on controllability of short and long task mental imagery.
