| Research Abstract |
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.
