Effects Of Creatine Supplementation On Oxidative Stress And Inflammatory Markers After Repeated-sprint Exercise In Humans

Effect Decrease
Trial Design Double blind
Trial Length 1-7 Days
Number of Subjects 25
Sex Male
Age Range 13-17, 18-29
Body Types Trained, Average
Notes for this study:
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.
