Values are means (95% CIs). Sample sizes/group at 3, 6, 9, and 12 wk, respectively—MDP: n = 20, 17, 16, and 16; PB: n = 23, 23, 23, and 22; and WP: n = 20, 20, 19, and 18. MDP, maltodextrin placebo; PB, soy-dairy protein blend; WP, whey protein; 1-RM, 1 repetition maximum; ∆, change.

The mean represents the mean 1-RM increase from all of the exercises used in training.
