Abstract

âº Young, female gymnasts vs. non-gymnasts: radius and femoral neck DXA-derived indices. âº Two-factor ANCOVA tested for gymnastic exposure and maturity: effects, interactions. âº Gymnastics: greater geometry and strength benefits at radius than femoral neck. âº Gymnastics: larger cortices at both sites, wider radii vs. narrower femoral necks. âº Gymnasts gain skeletal strength via maturity- and site-specific geometric adaptation.
