Values are means ± SEMs. Sample sizes/group at baseline, 6 wk, and 12 wk, respectively—MDP: n = 17, 14, and 14; PB: n = 22, 22, and 21; and WP: n = 17, 15, and 14. Labeled means (at that time point) without a common superscript letter differ, P < 0.05. *Different from baseline, P < 0.05. MDP, maltodextrin placebo; PB, soy-dairy protein blend; WP, whey protein.
