EFFECT OF COFFEE CONSUMPTION ON ANAEROBIC PERFORMANCE

The purpose of this study was to determine the effect of coffee ingestion on anaerobic performance of coffee drinkers. Wingate bicycle tests were applied before and after 10 days coffee consumption. In a randomized and double blind design, one group of subjects consumed coffee (3 mg caffeine/kg/day) and other group of subjects consumed decaf coffee for ten days between two Wingate tests. Wilcoxon Signed Ranks Test test were applied between pre and post-tests of the group. Effect size (ES) was calculated using Cohen’s delta to evaluate the size of mean differences. Results of this study indicated that peak power increased in just caffeinated coffee group when compared to baseline (p<0.05). As a conclusion it can be said that long time coffee with caffeine ingestion has a positive effect on anaerobic performance.
