Aim of this research was investigating of the effect of transcranial direct current stimulation on the working memory in athletes and nonathletes. To this end, 48 persons (18-30 years) purposefully was selected and was equally assigned into two athletes and nonathletes groups. Then, each group was randomly divided to tow actual and artificial stimulation sub-groups. The actual and sham stimulation presented with 2 mA electric current intensity for 20 minutes within three sessions. N-back computer task was used to measure working memory. The results showed the athlete's group rather than nonathlete and the actual stimulation group compared to the Sham group had better performance. The athlete group progressed in the actual stimulation in the post-test. Direct electrical stimulation of the brain so that anodal stimulation on left dorsolateral prefrontal cortex and catodal stimulation on right dorsolateral prefrontal cortex improve of working memory in athlete.
