Effect of oral creatine supplementation on power output and fatigue during bicycle ergometry

S. Barnes. Effect of oral creatine supplementation on power output and fatigue during bicycle ergometry. J. Appl. PhysioZ. 78(2): 670-673, 1995.-Our purpose was to determine the effect of oral creatine supplementation on exercise perfor-mance during high-intensity short-duration bicycle sprint-ing. Power output was recorded for 12 healthy untrained males (age 24.08 t 0.53 yr, weight 81.22-+ 1.32 kg) before and after 5 days of creatine (n = 6) or placebo (n = 6) supple-mentation. A double-blind research design was employed. Subjects performed maximal sprints against a constant load (111.8 N) for 15 s. Each one-half pedal revolution was mag-netically counted, and subsequent measurements of peak power, time to peak power, total work, and the fatigue index were digitized and stored on disk. Mean values for peak power, time to peak power, total work, and fatigue index wer
