  1. aIndicates an increase in peak torque across the 28 days of supplementation that exceeded the minimal important difference (pooled pre-supplementation S.D. × 0.5 effect size = 13.29 N·m). b Indicates a significantly (p < 0.05) greater proportion of individual subjects that exceeded the minimal important difference than the placebo group as determined by χ2 analyses
