この研究の注釈：
In otherwise healthy men subject to sleep deprivation after 7 days of creatine loading, supplementation failed to have any effect when measured at 12-24 hours yet was able to improve executive functioning at 36 hours. Mood, cortisol, and memory were all still unaffected relative to placebo.

この研究の注釈：
A week of creatine loading prior to sleep deprivation appears to not influence cortisol or serum catecholamines, but was associated with less reports of fatigue and more vigor relative to placebo. Despite the improved mood state, cognition during the 24 hours of testing was not significantly altered
