abstract = {The inverse effects of creatine supplementation and sleep
deprivation on high energy phosphates, neural creatine, and
cognitive performances suggest that creatine is a suitable
candidate for reducing the negative effects of sleep
deprivation. With this, the main obstacle is the limited
exogenous uptake by the central nervous system (CNS), making
creatine only effective over a long-term diet of weeks. Thus
far, only repeated dosing of creatine over weeks has been
studied, yielding detectable changes in CNS levels. Based on
the hypothesis that a high extracellular creatine
availability and increased intracellular energy consumption
will temporarily increase the central creatine uptake,
subjects were orally administered a high single dose of
creatinemonohydrate (0.35 g/kg) while performing cognitive
tests during sleep deprivation. Two consecutive 31P-MRS
scans, 1H-MRS, and cognitive tests were performed each at
evening baseline, 3, 5.5, and 7.5 h after single dose
creatine (0.35 g/kg) or placebo during sub-total 21 h sleep
deprivation (SD). Our results show that creatine induces
changes in PCr/Pi, ATP, tCr/tNAA, prevents a drop in pH
level, and improves cognitive performance and processing
speed. These outcomes suggest that a high single dose of
creatine can partially reverse metabolic alterations and
fatigue-related cognitive deterioration.},
