  1. † = Significant change (p < 0.05) within each group from each group’s respective baseline; Time Main effect for time; p probability level of making Type I error; 95% CI = 95% confidence intervals were computed on the observed changes from baseline between groups; ES = Effect size calculated as ([Week 10 Rice Protein – Week 2 Rice Protein] – [Week 10 Whey Protein – Week 2 Whey Protein]) / Pooled SD. Wingate power drop = Wingate maximum power – Wingate minimum power
