In the past century, numerous articles have explored enhancing sports performance, primarily focusing on aspects such as physical training, fatigue, and physiological parameters. Nevertheless, in recent decades, there has been a notable recognition of the pivotal role played by cognitive parameters in achieving superior results. Over the last decade, the volume of articles specifically addressing mental fatigue has surged into the thousands. Consequently, various strategies aimed at mitigating its adverse effects have emerged in the literature. These strategies encompass cognitive training and the use of substances such as caffeine. Furthermore, it has been observed that these interventions may not only alleviate the negative impact of mental fatigue but also enhance performance concerning baseline values. Despite these advancements, a comprehensive understanding of these phenomena remains elusive, and there is a pressing need for the development of a substantial body of evidence to unravel the intricacies involved.
