Using the permitted athletic supplementations in recent years has become one of the most important parts of an athlete’s preparation for participating in competitions. The purpose of this study is to investigate the effect of plyometric exercises with creatine supplementation on the active academic athlete’s fitness factors. Hence, for operating such a research, 60 student athletes were selected randomly in four groups, each group with 15 athletes, and the groups were studied as follows: 1: Plyometric exercise with creatine supplementation 2: Plyometric exercise with placebo consumption, 3: Plyometric exercise without supplementation consumption And 4: Control. For measuring the maximum power of lower body organs the leg press test, for measuring the muscular power in lower body organs, the Sargent Jump Test and for measuring the speed the 60-meter sprint were used. After getting the subjects’ records in the pre-test stage, the subjects of the three experimental groups, did the plyometric exercises with a similar plan, for six weeks; four sessions a week. With this difference that the first group subjects received creatine supplementation, the second group were given placebo, the third group subjects did not receive any supplementation and the fourth group subjects continued their daily activities. In order to analyze the data, the descriptive statistics, the statistical test of one-way analysis of variance (F) and Tukey's Post Hoc Test (P<0.05) were used. The results showed that in the posttest period, there is a meaningful difference between the data related to lower body organs’ muscular power and the muscular groups of the four groups’ subjects which illustrates the improvement of the measured factors after the exercise period’s activities andcreatine supplementation consumption. Considering the research’s findings, it is suggested that in designing the exercise plans for athletic fields which need speed performance similar to 60- meter sprint, the plyometric exercises and creatine supplementation feeding be used.
