Abstract: The objective of the present study was to investigate the impact of eight weeks of creatine monohydrate (Crm) supplementation on the anaerobic performance of young trained adults. Twenty-six healthy male physical education students were randomly divided in creatine group (CrG, n = 13; 22.5 ± 2.7 years; 74.9 ± 6.8 kg; 178.5 ± 4.8 cm) and placebo group (PlG, n = 13; 22.9 ± 3.2 years; 71.9 ± 11.3 kg; 178.6 ± 4.0 cm). The subjects received in a double-blind system a Crm or placebo-maltodextrin dose (20 g.d-1 for 5 days and 3 g.d-1 for 51 subsequent days). Both groups had their eating habits and levels of physical fitness previously controlled. The Wingate anaerobic test (WT) was used to evaluate the anaerobic performance before and after the ingestion period of Crm or placebo. The performance indexes assessed were: relative peak power (RPP), relative mean power (RMP), relative total work (RTW) and index of fatigue (IF). ANOVA followed by Tukey post hoc test were used when P<0.05 for statistical treatment. No significant difference in RPP, RMP, RTW or IF was observed after the period of supplementation of Crm (P>0.05). The results of the present study suggest that Crm supplementation does not seem to be an efficient ergogenic resource in high-intensity and short-duration efforts involving a single set.
