There were no significant differences between EXP and CON groups of pre-PHV and post-PHV maturity groups (all p=0.081-0.451). Post-PHV boys in the EXP group were chronologically older, taller and heavier than their counterparts in the pre-PHV EXP group (all p<0.001), and post-PHV boys in the CON group were chronologically older, taller and heavier than their counterparts in the pre-PHV CON group (all p<0.001-0.001).
