Data indicate sprinting times with ingestion of 15, 30, and 60 g/h of 2:1 glucose: fructose (mean total repetitions ± SD) and %improvement in sprinting time [1st line: %improvement, 90 % confidence interval limits, and Cohen’s effect size (ES; in parentheses); 2nd line: chances (% and qualitative) of meaningful improvement (>0.5 % CV) and sample size needed for a magnitude-based inference about the practical significance of the observed changes in performance for a power of 80 % (in parentheses); 3rd line: exact P value from pairwise t-tests]
