1 Values presented as mean ± SEM; 2 Labeled values with different lowercase letters on the same row are significantly different between trials, p < 0.05. CHO: high-carbohydrate breakfast trial; CHO + WP: high-carbohydrate breakfast with added whey protein trial; iAUC: net incremental area under the curve; NB: no breakfast trial.
