Abstract:	The purpose of this study was to investigate the effects of creatine monohydrate supplementation on anaerobic capacity. By means of 30-s Wingate anaerobic test, the peak anaerobic power (Peak-AnP), anaerobic capacity (AnC), mean anaerobic power (M-AnP) and fatigue index (FI) were measured to evaluate the effects of creatine monohydrate supplementation on anaerobic capacity. Twenty healthy men from college who were not taking regular exercise, were included, and randomly assigned to creatine group (n=10) or placebo group (n=10). The study was double-blind. The subjects were supplemented with a dose of 0.25g/kg creatine (creatine group) or maltodextrin (placebo group) three time per day within 6 subsequent days. Before and after the starting of the study, body weight and thickness of skin fold were measured, while the 30-s Wingate anaerobic test was performed to show the anaerobic capacity. Blood sample from ntecubital vein was also collected to measure GOT, GPT, BUN, creatinine, and the peak of postexercise blood lactic acid level. The experimental data is analyzed statistically by t-test and the results obtained are: (1) the supplement of Creatine monohydrate does not have significant effect on the body weight and the fat percentage; (2) the peak value of the blood lactic acid measured after exercising increased significantly (P＜.05) as compared with that of the prior measurement; (3) the Peak-AnP and AnC measured from the creatine monohydrate group after experiment increased significantly (P＜.05) as compared with that of the placebo group; (4) in creatine monohydrate group, the M-AnP after the experiment increased significantly (P＜.05) as compared with that before experiment; (5)after experiment, FI% in the creatine monohydrate group significantly increased as compared with that of the placebo group (P＜.05); and (6) the blood biochemical value was within the normal range before or after the experiment. This study reveals that, the supplement of creatine monohydrate does significantly increase the anaerobic capacity, but does not have significantly increasing effect on the consecutive of the anaerobic exercise. It could not make sure that the supplement of the creatine monohydrate has direct effect on the peak value of the blood lactic acid after taking exercise.
