Infographic - Creatine & Mental Fatigue

  • September 26, 2019
  • Creatine supplementation improved physical (strength endurance) and prolonged cognitive (Stroop accuracy) performance.
  • Creatine supplementation had no effect on short sport-specific psychomotor or cognitive (Flanker) performance, nor did it have any effect on the mental fatigue-induced reduction in performance on these tasks.
  • The improved prolonged cognitive performance indicates that creatine supplementation might be able to partially counteract the mental fatigue-induced reduction in performance. 
  • From a practical point of view, these results indicate that further research into the possible role of creatine supplementation in countering mental fatigue-induced performance reductions in long-term tasks (e.g. a 90-min football match) is warranted. 
  • From a mechanistic point of view, these results suggest a possible role for brain phosphocreatine in mental fatigue.
