Outcome Measures

Primary Outcomes (2)

  • Cognitive performance - change in accuracy (%) during a 90-min cognitive task (i.e. Stroop task)

    Accuracy (in %) will be assessed during a cognitive task, this cognitive task will be completed after both 7-day supplementation protocols (i.e. placebo and creatine)

    During both lab visits (i.e. after both 7-day supplementation protocols); Accuracy (%) will be assessed during both lab visits with a 90-min cognitive task; Accuracy during the 90-min task will be reported as mean accuracy during 8 blocks of 11min15sec

  • Cognitive performance - change in reaction time (milliseconds) during a 90-min cognitive task (i.e. Stroop task)

    Reaction time (in milliseconds) will be assessed during a cognitive task, this cognitive task will be completed after both 7-day supplementation protocols (i.e. placebo and creatine)

    During both lab visits (i.e. after both 7-day supplementation protocols); Reaction time (RT) will be assessed during both lab visits with a 90-min cognitive task; RT during the 90-min task will be reported as mean RT during 8 blocks of 11min15sec

Secondary Outcomes (1)

  • Physical performance - reaction time (milliseconds) during a 7-min visuomotor reaction time task

    During both lab visits (i.e. after both 7-day supplementation protocols); visuomotor reaction time will be assessed during both lab visits with a 7-min visuomotor reaction time task.
