SUMMARY

The investigation aimed to determine the effects of the two-week creatine monohydrate supplementation and specially designed training program on anaerobic power and body composition in judo athletes. A total of 12 athletes was divided into the creatine (C) and placebo (P) groups. During the first week, the C group subjects (n=6) were given a prepared aqueous solution of creatine monohydrate and dextrose four times a day. During the second week, subjects were given the prepared solutions once a day. The P group subjects (n=6) were involved in the same protocol and at the same time were given only a dextrose solution. All subjects were included into specially designed training program composed of strength training and perfecting of specific judo techniques. The investigation protocol consisted of Wingate test for the upper extremities, the assessment of body composition and special judo fitness test (SJFT). The comparison of results between the groups before and after the process of supplementation showed a significant difference only in relation to the values of anaerobic capacity. The results were analyzed for each group alone before and after supplementation. In the C group subjects, there is a significant difference in the values of anaerobic power and fat mass percentage observed during the Wingate test, whereas no significant difference was found in the values of SJFT. Obtained results show that the two- week creatine monohydrate supplementation and specially designed training program, although of shorter duration than those described in the literature, have a significant effect on anaerobic power and body composition.
