Over the past decade, the number of studies on cognitive performance in esports has increased in line with its popularity. Cognitive functions like task switching, information processing, attention, and memory have been identified as an integral part of cognitive performance. In parallel, different types of training, ranging from physical to a combination of cognitive and motor tasks, have emerged as promising strategies to improve cognitive function and thus performance of esports players. However, only acute high-intensity interval training was studied in esports players and exclusively in recreational players. Due to the lack of specialized training programs for esports coaches, the small number of professional esports players and the relative youth of professional esports practice, there is a large gap in the literature regarding cognitive performance training methods to improve the cognitive performance of professional esports players. Based on these results, the present invited commentary encourages further studies to be conducted among professional esports players. Indeed, research perspectives are necessary to develop training protocols and optimal training schedules to improve professional esports players’ performance. In addition, this commentary supports the collaboration between academic and professional esports organizations. Finally, we provide recommendations to allow a win-win condition for both researchers and professional esports players in the future.
