この研究の注釈：

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
