Data are expressed as means ± SD. Between-group comparisons of pre-intervention values were performed using ANOVA. Between-group comparisons of post-intervention values and variations were performed using ANCOVA, with the pre-intervention value as a factor. (*, p < 0.05; **, p < 0.01; Placebo vs. SNK-L; Placebo vs. SNK-H).
