Effect None
Trial Design Double blind
Trial Length n/a
Number of Subjects 40
Gender n/a
Notes for this study:
Reduced fatigue rates were noted with 6g creatine monohydrate supplemented for 6 days, but no performance differences were noted from placebo.

Number of Subjects 16
Gender n/a
Notes for this study:
Double blind crossover design, results confounded with sodium bicarbonate usage.

20g creatine monohydrate daily for 6 days, with sodium bicarbonate at 0.3g/kg bodyweight on the 7th day before testing.

Low Dose Creatine Supplementation Enhances Sprint Phase Of 400 Meters Swimming Performance

Effect Increase
Trial Design Double blind
