Femur 3D-DXA Assessment in Female Football Players, Swimmers, and Sedentary Controls
Int J Sports Med DOI: 10.1055/a-1928-9824Cortical and trabecular volumetric bone mineral density (vBMD), cortical
thickness and surface BMD (sBMD, density-to-thickness ratio) were analyzed in
the proximal femur of elite female football players and artistic swimmers using
three-dimensional dual-energy X-ray absorptiometry (3D-DXA) software and
compared to sedentary controls. Football players had significantly higher
(p<0.05) vBMD (mg/cm3) in the trabecular
(263±44) and cortical femur (886±69) than artistic swimmers
(224±43 and 844±89) and sedentary controls (215±51 and
841±85). Football players had also higher (p<0.05) cortical
thickness (2.12±0.19 mm) and sBMD
(188±22 mg/cm2) compared to artistic
swimmers (1.85±0.15 and 156±21) and sedentary controls
(1.87±0.16 and 158±23). Artistic swimmers did not show
significant differences in any parameter analyzed for 3D-DXA when compared to
sedentary controls. The 3D-DXA modeling revealed statistical differences in
cortical thickness and vBMD between female athletes engaged in weight-bearing
(football) and non-weight bearing (swimming) sports and did not show differences
between the non-weight bearing sport and the sedentary controls. 3D-DXA modeling
could provide insight into bone remodeling in the sports field, allowing
