—The PPO of the lower body in the WP (n = 11) and CP (n = 11) groups before and after the 10-week RT program. The box plot shows the median (line) and mean (+), interquartile range (box), and the maximum and minimum values (whiskers). ap < .05 compared with pretraining values for both groups (ANOVA; time effect). There were no significant differences between groups (ANOVA; Group × Time interaction, p > .05). CP = collagen peptides; WP = whey protein; ANOVA = analysis of variance; RT = resistance training; PPO = peak power output.
