The aim of the present study was to investigate the effect of auditory focus with high and low cognitive load on adolescent sports performance and working memory. The present study was conducted quasi-experimentally and Its statistical population included adolescent primary and secondary school students in Koohnani. The statistical sample was 20 students with an age range of 11-13 years. Participants were randomly divided into two groups of auditory attention focus with high and low cognitive load and in the pre-test performed working memory task with N-BACK software and 6 football chip hits towards the target. The acquisition stage was performed in 4 days.. 7 days after the final acquisition session, N-BACK working memory test, delay retention and transfer test  were taken from the participants. The results of combined analysis of variance test with repeated measures showed that the effect of auditory focus with high cognitive load on sports performance and working memory was significant (p <0.05) and the other group showed improvement only in working memory (p <0.05). Based on the results of the present, cognitive load manipulation affects work memory and athletic performance.
