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.
