The aim of this study was to compare geometric indices of hip bone strength in female football players and controls.
18 adult female football players and 18 adult sedentary females participated in this study. The two groups were paired for age, weight and body mass index (BMI). Daily calcium intake (DCI) and daily protein intake (DPI) were evaluated by questionnaires. Total hip bone mineral density (BMD) and femoral neck BMD were measured by DXA. Cross-sectional area (CSA), an index of axial compression strength, section modulus (Z), an index of bending strength and cortical thickness (CT) were evaluated at the femoral neck (FN), the intertrochanteric (IT) and the femoral shaft (FS) regions by the hip structure analysis (HSA) program.
Age, weight, height, BMI, DCI and DPI were not different between the two groups. TH BMD, FN BMD, FN CSA, FN Z, FN CT, IT CSA, IT Z, IT CT, FS CSA and FS Z were significantly higher in football players compared to controls (crude percentage differences between the two groups varied between 8 and 19%; P<0.05). After adjusting for body weight using a one-way analysis of covariance (ANCOVA), TH BMD, FN BMD, FN CSA, FN Z, FN CT, IT CSA, IT Z, IT CT, FS CSA and FS Z remained significantly higher in football players compared to controls (adjusted percentage differences between the two groups varied between 7 and 17%; P<0.05).
This study suggests that, in adult females, football practice is associated with greater geometric indices of hip bone strength.
本研究旨在比较女性足球运动员与对照组的髋部骨强度几何指标。
18名成年女性足球运动员和18名成年久坐女性参与了本研究。两组在年龄、体重和体重指数（BMI）方面进行了配对。通过问卷调查评估每日钙摄入量（DCI）和每日蛋白质摄入量（DPI）。采用双能X线吸收法（DXA）测量全髋骨密度（BMD）和股骨颈BMD。通过髋部结构分析（HSA）程序在股骨颈（FN）、转子间（IT）和股骨干（FS）区域评估轴向抗压强度指标横截面积（CSA）、抗弯强度指标截面模量（Z）和皮质厚度（CT）。
两组之间的年龄、体重、身高、BMI、DCI和DPI无差异。与对照组相比，足球运动员的全髋BMD、股骨颈BMD、股骨颈CSA、股骨颈Z、股骨颈CT、转子间CSA、转子间Z、转子间CT、股骨干CSA和股骨干Z显著更高（两组之间的原始百分比差异在8%至19%之间；P<0.05）。使用单因素协方差分析（ANCOVA）对体重进行校正后，与对照组相比，足球运动员的全髋BMD、股骨颈BMD、股骨颈CSA、股骨颈Z、股骨颈CT、转子间CSA、转子间Z、转子间CT、股骨干CSA和股骨干Z仍然显著更高（两组之间的校正百分比差异在7%至17%之间；P<0.05）。
本研究表明，在成年女性中，进行足球运动与更大的髋部骨强度几何指标相关。
