The aim was to investigate the effect of caffeine on anaerobic power intermittently trained cyclists. Ten athletes underwent two experimental sessions in a model randomized double-blind study. In each session, subjects ingested a random capsule caffeine (6 mg / kg) or placebo. One hour after, two tests Wingate were carried (T1, T2) for determining the anaerobic performance with 4 min of rest between each exercise bout. Statistical analysis used ANOVA for repeated measures revealed no significant differences between the caffeine and placebo trials. In comparing intra-tests was significantly reduced only to Mean Power (W) between sessions with caffeine (T1c: 673.6 ± 59.5 vs. T2c: 589.0 ± 58.8). The acute oral intake of caffeine did not contribute to the increase in intermittent anaerobic performance, however, the reduction in average power with the use of caffeine, may suggest a preference for fatty acid metabolism, which would be disadvantageous during intermittent maximal efforts.
