PURPOSE The purpose of this study was to investigate the difference between the performance level and working memory of athletes through behavioral response measurements and hemodynamic measurements of the prefrontal cortex. METHODS The study included 12 higher-level athletes, 12 athletes, and 12 non-athletes. The study task was to perform auditory-Spatial working memory tasks according to difficulty (1 back, 2 back). Reaction times and hemodynamic changes in the cerebral prefrontal cortex were measured using the NIRSIT instrument during task performance. RESULTS Behavioral response measurements of the superior players showed faster reaction times in the 1-back and 2-back tasks compared to the other two groups, and the functional connectivity of the cerebral prefrontal cortex showed strong activation in the 2-back task. CONCLUSIONS In the case of higher-level athletes, it is suggested that working memory ability and motor performance are significant, and that working memory ability can be an important variable in sports situations.
