Flow chart of the subject selection process. Out of 294 subjects who were screened, 114 subjects were included in the study. These subjects were randomly allocated to whey peptide (n = 57) and placebo (n = 57) groups. Three subjects in the whey peptide group and one subject in the placebo group dropped out of the study during the intervention. Three subjects in the whey peptide group and three in the placebo group were excluded from analysis, leaving 51 and 53 subjects in whey peptide and placebo groups, respectively, for analysis.
