Analysis of femoral morphometrical and mechanical properties using by MRI in Japanese top athletes

在日本顶级运动员中，使用MRI测量股骨中段的横截面形态测量和力学特性，以及骨生物标志物，以研究运动（对骨的影响水平）与成骨反应之间的关系。受试者被分为5组，根据每个性别的影响程度。因此，在两种性别中，与低撞击组相比，高撞击组具有显著更大的皮质面积、骨膜周长和骨强度。另一方面，骨标志物在各组之间没有变化。

The cross-sectional morphometrical and mechanical properties at mid-femur using MRI, and bone biomarkers were measured in Japanese top athletes, to investigate relationships between exercise(impact levels on bone) and osteogenic responses. The subjects were divided into 5 groups according to impact levels in each sex. As a result, higher impact groups had significantly greater cortical area, periosteal perimeter and bone strength compared to lower impact groups in both sexes. On the other hand, bone markers did not change among groups.
