creatine-fatigue

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

この研究の注釈：

In youth, 300 mg/kg/day for 1 week was able to improve performance on a repeated sprint test (35-m sprints, repeated six times with 10-s rests) relative to placebo, but this was not associated with any change in fatigue (assessed via fatigue index) or in biomarkers of oxidative stress, although inflammation was attenuated.

There were unclear effects on muscle damage, since creatine kinase increased while LDH (lactate dehydrogenase, a liver enzyme) decreased.

この研究の注釈：

Supplementation of 5g of creatine with orange juice (7g carbohydrate) twice daily for a week appears to enhance swimming performance in the 400m sprint by selectively increasing the final 50m stretch, and there was also increased performance on a Wingate test (anaerobic capacity and power output) and the fatigue associated with the Wingate test.

400 mg/kg/day was given for 6 months to children and adolescents who suffered from traumatic brain injury. The number of individuals who reported dizziness was reduced by half, while the frequency of symptoms of fatigue and headache was reduced from around 90% to near 10%.

この研究の注釈：

10 g/day for 3 months in individuals with myotonic dystrophy type II (DM2 or PROMM) failed to alter power output but significantly improved subjective well-being relative to placebo (mainly less exhaustion following physical exercise).

この研究の注釈：

5 g/day for 9 months (following 10 g/day for five days) failed to benefit well-being, functional capacity, lung function, or muscular capacity as assessed by Maximal Voluntary Isometric Contraction (MVIC). The treatment proved safe, however, and the risk of death was nonsignificantly reduced.

8 g/day (2 g four times a day) for 5 five days reduced the mental fatigue of subjects who repeatedly performed simple mathematical calculations, as their brains saw an increase in oxygen utilization.
