Past studies have mainly used Stroop tasks to induce mental fatigue in soccer.However, due to the non-sport-specificity of these tasks, their transferability to the real-life effects of mental fatigue in soccer have been questioned. To address this methodological issue, we developed two different versions of a soccer passing task via the so-called Footbonaut: a mentally more demanding decision-making and inhibition task in the experimental condition, and a mentally less demanding standard task of the Footbonaut in the control condition. The study's aim was to investigate the effects of the two different versions of the Footbonaut task on cognitive and soccer-specific performance. A randomised, counterbalanced experimental within-subjects design was employed (N = 27). Participants showed significantly worse soccer-specific performance in the experimental condition compared to the control condition. No corresponding effects were revealed in cognitive performance.Study limitations and mechanisms why cognitive performance was not negatively affected are being discussed.
