Will an athlete perform at their highest level if they have experienced mental fatigue beforehand? Until recently, research seemed to conclude otherwise. However, recent studies challenge the idea that mental fatigue affects subsequent physical performance. Alongside the poor replicability of one of the most cited studies in the field, two review and meta-analytical studies indicate the lack of statistical power in previous studies along with significant publication bias. Therefore, as of today, the evidence does not allow us to conclude that mental fatigue negatively affects physical performance.
