cognitive and psychomotor challenges, fatigue
Video gaming and esports have become an increasingly popular, highly competitive, and multibillion-dollar industry [An emerging area of performance enhancement is identifying nutritional strategies to help individuals improve and/or maintain cognitive function during work and/or competition. Several studies have evaluated the effects of nutritional supplementation on cognitive function and/or video game performance. For example, Cereda and coworkers [Regarding gaming performance, Kalman et al. [Present findings are consistent with our previous findings [Nutritional strategies intended to enhance cognitive function have focused on increasing blood flow [The strengths of this study were that it evaluated the effects of low and high-dose supplementation with Limitations included assessing the performance of several different game versions and play modes, which made the interpretation of performance more difficult, given the differences among games and their scoring parameters. There also could have been differences in energy, mental focus, cognitive and psychomotor challenges, and fatigue associated with playing different games. These differences may have increased variability among participants in cognitive function assessments. Furthermore, despite practicing the cognitive function tests, normal variability in performing cognitive function tests may have increased type II error. Assessing a cohort primarily comprised of men was also a limitation.Future research should select one game to evaluate or simulate an esport tournament and consider monitoring weekly adaptations during gaming practice sessions on performance adaptations. Additional research should also assess the effects of acute and chronic
