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

摘要: Our purpose was to determine the effect of oral creatine supplementation on exercise performance during high-intensity short-duration bicycle sprinting. Power output recorded for 12 healthy untrained males (age 24.08 +/- 0.53 yr, weight 81.22 1.32 kg) before and after 5 days (n = 6) or placebo supplementation. A double-blind research design employed. Subjects performed maximal sprints against a constant load (111.8 N) 15 s. Each one-half pedal revolution magnetically counted, subsequent measurements peak power, time total work, fatigue index were digitized stored disk. Mean values 958.01 40.66 W, 4.09 0.82 s, 11.28 0.46 kJ, 32.1 1.58% decline from respectively. No significant differences observed within between groups any mechanical parameters measured (P > 0.05). These findings suggest that does not positively affect power continuous in men.
