From: Effects of post exercise protein supplementation on markers of bone turnover in adolescent swimmers
Relative serum concentrations (mean ± SEM) of procollagen type 1 intact N-terminal propeptide (PINP) 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%. No significant main effects were observed for time, group or sex, and no significant interactions
