From: Effects of post exercise protein supplementation on markers of bone turnover in adolescent swimmers
Relative changes in serum concentrations (mean ± SEM) of carboxy-terminal collagen crosslinks (CTXI) following the two post-exercise supplement beverages (i.e., 8 h and 24 h from baseline) in adolescent female and male swimmers, where baseline values are taken as 100%. There was a significant main effect for time (F = 11.48, p = 0.001, ηp2 = 0.18) and a significant time-by-group interaction (F = 4.88, p = 0.001, ηp2 = 0.16), reflecting a significant decrease (*p = 0.04) from 8 h to 24 h in the protein group only
